Despite the growth of adaptation plans and action by municipalities, there are limited examples of opportunities for effectively mainstreaming climate adaptation into policy and practice in local government. This paper uses the experiment of co-producing an adaptation plan for a small municipality in the Western Cape Province, South Africa, to illustrate how opportunities were leveraged. The findings suggest that a shift from strengthening the science–policy interface to the knowledge–policy interface might be more appropriate in the context of adaptation planning that requires an understanding of the local context as well as of global science. In order to align adaptation plans with developmental priorities and to secure support from actors at multiple levels, the integration of multiple knowledge forms, including climate science, should be prioritized. Such a task could be strengthened if co-production is prioritized. Building on these opportunities is critical to scaling up adaptation in local government and building on its transformative potential. [ABSTRACT FROM AUTHOR]

The Global Polio Eradication Initiative (GPEI) was launched in 1988 with the aim of completely clearing wild polio viruses by 2000. More than three decades later, the goal has not been achieved, although spectacular advances have been made, with wild polio virus reported in only 2 countries in 2019. In spite of such progress, novel challenges have been added to the equation, most importantly outbreaks of vaccine-derived polio cases resulting from reversion to neurovirulence of attenuated vaccine virus, and insufficient coverage of vaccination. In the context of the latest discussions on malaria eradication, the GPEI experience provides more than a few lessons to the malaria field when considering a coordinated eradication campaign. The WHO Strategic Advisory Committee on Malaria Eradication (SAGme) stated in 2020 that in the context of more than 200 million malaria cases reported, eradication was far from reach in the near future and, therefore, efforts should remain focused on getting back on track to achieve the objectives set by the Global Technical Strategy against Malaria (2016–2030). Acknowledging the deep differences between both diseases and the stages they are in their path towards eradication, this paper draws from the history of GPEI and highlights relevant insights into what it takes to eradicate a pathogen in fields as varied as priority setting, global governance, strategy, community engagement, surveillance systems, and research. Above all, it shows the critical need for openness to change and adaptation as the biological, social and political contexts vary throughout the time an eradication campaign is ongoing.

Forest biomass allocation is a direct manifestation of biological adaptation to environmental changes. Studying the distribution patterns of forest biomass along elevational gradients is ecologically significant for understanding the specific impacts of global change on plant resource allocation strategies. While aboveground biomass has been extensively studied, research on belowground biomass remains relatively limited. Furthermore, the patterns and driving factors of the belowground biomass proportion (BGBP) along elevational gradients are still unclear. In this study, we investigated the specific influences of climatic factors, soil nutrients, and key leaf traits on the elevational pattern of BGBP using data from 926 forests at 94 sites across China. In this study, BGBP data were calculated from the root biomass to the depth of 50 cm. Our findings indicate considerable variability in forest BGBP at a macro scale, showing a significant increasing trend along elevational gradients (p < 0.01). BGBP significantly decreases with increasing temperature and precipitation and increases with annual mean evapotranspiration (MAE) (p < 0.01). It decreases significantly with increasing soil phosphorus content and increases with soil pH (p < 0.01). Key leaf traits (leaf nitrogen (LN) and leaf phosphorus (LP)) are positively correlated with BGBP. Climatic factors (R2 = 0.46) have the strongest explanatory power for the variation in BGBP along elevations, while soil factors (R2 = 0.10) and key leaf traits (R2 = 0.08) also play significant roles. Elevation impacts BGBP directly and also indirectly through influencing such as climate conditions, soil nutrient availability, and key leaf traits, with direct effects being more pronounced than indirect effects. This study reveals the patterns and controlling factors of forests' BGBP along elevational gradients, providing vital ecological insights into the impact of global change on plant resource allocation strategies and offering scientific guidance for ecosystem management and conservation.

Nighttime object detection is challenging due to dim, uneven lighting. The IIHS research conducted in 2022 shows that pedestrian anti-collision systems are less effective at night. Common solutions utilize costly sensors, such as thermal imaging and LiDAR, aiming for highly accurate detection. Conversely, this study employs a low-cost 2D image approach to address the problem by drawing inspiration from biological dark adaptation mechanisms, simulating functions like pupils and photoreceptor cells. Instead of relying on extensive machine learning with day-to-night image conversions, it focuses on image fusion and gamma correction to train deep neural networks for dark adaptation. This research also involves creating a simulated environment ranging from 0 lux to high brightness, testing the limits of object detection, and offering a high dynamic range testing method. Results indicate that the dark adaptation model developed in this study improves the mean average precision (mAP) by 1.5−6% compared to traditional models. Our model is capable of functioning in both twilight and night, showcasing academic novelty. Future developments could include using virtual light in specific image areas or integrating with smart car lighting to enhance detection accuracy, thereby improving safety for pedestrians and drivers.

Although growing urbanization has direct negative consequences for local biodiversity, several native species have been observed maintaining populations in urban environments. Understanding which factors influence the ability of native species to persist in urban environments is crucial, both for the study of biological adaptation and of urban planning. The quantification of the proportion of juvenile individuals can be a good proxy for assessing the long-term persistence of urban populations. We present comparative data about spatial and temporal variations in the age-class structure in two suburban and two forest populations of the Cuban endemic lizard Anolis homolechis, obtained during a 20-month survey. We found a four-fold lower proportion of juveniles in the suburban habitat compared to the forest one. There was, however, no evidence for differential female fecundity between the two habitats, as assessed by the proportion of gravid females. Conversely, the rate of tail autotomy (an antipredator behavior) was significantly higher in the suburban juveniles compared to the forest ones, possibly reflecting a higher exposure to predators and, particularly, inter- and intraspecific cannibalism. However, tail loss at initial capture or habitat type had no effect on the probability of recapture of juveniles. We discuss the potential causes and consequences of a modified age-class structure in urbanized environments. [ABSTRACT FROM AUTHOR]

Expanding from remote areas of Mexico to a worldwide scale, the ten-striped insect, the Colorado potato beetle (CPB, Leptinotarsa decemlineata Say), has risen from being an innocuous beetle to a prominent global pest. A diverse life cycle, phenotypic plasticity, adaptation to adverse conditions, and capability to detoxify or tolerate toxins make this insect appear to be virtually "indestructible". With increasing advances in molecular biology, tools of biotechnological warfare were deployed to combat CPB. In the last three decades, genetically modified potato has created a new challenge for the beetle. After reviewing hundreds of scientific papers dealing with CPB control, it became clear that even biotechnological means of control, if used alone, would not defeat the Colorado potato beetle. This control measure once again appears to be provoking the potato beetle to exhibit its remarkable adaptability. Nonetheless, the potential for adaptation to these techniques has increased our knowledge of this pest and thus opened possibilities for devising more sustainable CPB management programs.

Although evidence is increasing that climate shocks influence human migration, it is unclear exactly when people migrate after a climate shock. A climate shock might be followed by an immediate migration response. Alternatively, migration, as an adaptive strategy of last resort, might be delayed and employed only after available in situ (in-place) adaptive strategies are exhausted. In this paper, we explore the temporally lagged association between a climate shock and future migration. Using multilevel event-history models, we analyze the risk of Mexico-US migration over a seven-year period after a climate shock. Consistent with a delayed response pattern, we find that the risk of migration is low immediately after a climate shock and increases as households pursue and cycle through in situ adaptive strategies available to them. However, about 3 years after the climate shock, the risk of migration decreases, suggesting that households are eventually successful in adapting in situ. [ABSTRACT FROM AUTHOR]

Human languages are extraordinarily complex adaptive systems. They feature intricate hierarchical sound structures, are able to express elaborate meanings and use sophisticated syntactic and semantic structures to relate sound to meaning. What are the cognitive mechanisms that speakers and listeners need to create and sustain such a remarkable system? What is the collective evolutionary dynamics that allows a language to self-organize, become more complex and adapt to changing challenges in expressive power? This paper focuses on grammar. It presents a basic cycle observed in the historical language record, whereby meanings move from lexical to syntactic and then to a morphological mode of expression before returning to a lexical mode, and discusses how we can discover and validate mechanisms that can cause these shifts using agent-based models. This article is part of the themed issue 'The major synthetic evolutionary transitions'. [ABSTRACT FROM AUTHOR]

Vulnerability to the health impacts of climate change will be shaped by the existing burden of ill- health and is expected to be highest in poor and socio-economically marginalized populations. Sub-Saharan Africa, in particular, is considered a highly vulnerable region. This paper analyses the vulnerability and adaptive capacity of rural Bakiga communities in southwestern Uganda to climate-sensitive health risks. The objectives were threefold: i) identify key climate-sensitive, community-identified health priorities; ii) describe and characterize determinants of sensitivity to these health priorities at the individual, community and regional levels; and iii) assess the adaptive capacity of Bakiga. Data collection employed a combination of individual and key informant interviews, biographies, future storylines, and Photovoice. Three key health risks were identified by the study communities (malaria, food insecurity, and gastrointestinal illnesses) - all affected by local climatic and environmental conditions, livelihoods, land use changes, and socio-economic conditions. Adaptation within these communities is dependent on their capacity to reduce sensitivities to identified health challenges among the potential of increasing exposures. Crop diversification, reducing deforestation, expanding of livestock rearing, transfer of traditional knowledge, and access to affordable health services are among potential strategies identified. We demonstrate significant existing vulnerabilities to present day climate-related health risks and highlight the importance of non-climatic processes and local conditions in creating sensitivity to health risks. Our place-based understanding is useful to inform interventions or policies aimed to reduce exposure and sensitivity and support adaptive capacity as the conditions these communities face are consistent with many other sub-Saharan African countries.

Transboundary river basins face significant threats from climate change, with the need for adaptation widely noted. In this paper we develop a theoretically-rooted indicator-based evaluation framework to identify transboundary river basins where the need for adaptation support is pronounced and prioritize where attention is best placed. The framework combines indicators which capture the broad level potential to adapt (adaptive capacity) and the actual preparedness for adaptation (adaptation readiness) at the level of transboundary institutions. Adaptive capacity and adaptation readiness have not previously been evaluated and compared within a single framework, and by combining them we gain a more comprehensive and nuanced basis for characterising and evaluating the adaptation landscape and diagnosing opportunities and constraints for adaptation. We apply the framework to 42 transboundary basins in Mediterranean Europe, the Middle East, North Africa and sub-Saharan Africa, which account for 15 % of global transboundary river basins, are home to over 550 million people, and cover 8 % of Earth's total land area. We find: 1) There is widespread need for improving national and transboundary institutional support for adaptation spanning basins of various economic, physical, and demographic characteristics; 2) Many transboundary basins in Africa have low adaptive capacity, but were found to have high readiness to begin adapting if resources were available; and 3) Improved coverage of River Basin Organisations and treaties with mandates to recognise and respond actively to climate change would underpin adaptation efforts across basins.

There is increasing interest in transformational adaptation to climate change in agriculture, i.e. adaptation that involves large-scale, novel responses to reduce vulnerability to climate risks. Transformational adaptation is less well understood than incremental adaptation, since there are few studies of agricultural enterprises making transformative changes in response to climatic change. This paper is an in-depth study of an agricultural company's attempt to implement transformational adaptation in response to climate change. We document the Peanut Company of Australia's (PCA) response to predicted climatic change by expanding its operations into Katherine, Northern Territory, after decades of below-average rainfall in their traditional production region in south-east Queensland. Our research question was: what conditions and processes influenced the outcome of the company's response? We conducted 37 semi-structured interviews with company, government and community representatives to examine diverse perspectives on PCA's expansion into Katherine and its subsequent strategic retreat. To reveal insights into why, when and how this attempted transformational adaptation occurred we reviewed the literature and identified Park et al.'s () Adaptation Action Cycles (AAC) framework and aspects from the organisational adaptation literature as useful for our analysis. Based on our findings, we revised the AAC framework to better reflect the way that incremental adaptation in situ can occur simultaneously with transformational adaptation at a new location. Our study illustrates that transformational adaptation in agriculture is difficult, complex, risky and costly and sometimes unsuccessful, revealing some of the challenges of and barriers to organisational adaptation in agriculture, especially when moving to a new location.

This paper presents conclusions and recommendations that emerged from the 7th World Recreational Fishing Conference ( WRFC) held in Campinas, Brazil in September 2014. Based on the recognition of the immense social and economic importance of recreational fisheries coupled with weaknesses in robust information about these fisheries in many areas of the world, particularly in many economies in transition, it is recommended to increase effort to build effective governance arrangements and improve monitoring and assessment frameworks in data-poor situations. Moreover, there is a need to increase interdisciplinary studies that will foster a systematic understanding of recreational fisheries as complex adaptive social-ecological systems. To promote sustainable recreational fisheries on a global scale, it is recommended the detailed suggestions for governance and management outlined in the United Nations Food and Agricultural Organization Technical Guidelines for Responsible Fisheries: Recreational Fisheries are followed.

Small islands are among regions most affected by the impacts of global climate change. They are regarded as particularly vulnerable, but from a different point of view, island societies also feature a particular sociocultural resilience, which distinguishes them from continental societies. How do social structures increase the adaptive capacity of small islands towards sea-level rise? I consider the concept of social capital as applicable in order to understand the role of communities and collective action in a context of vulnerability and resilience. In this paper, I present results from a case study on the Isles of Scilly, UK. A mixed methods qualitative approach has been applied to analyse the various roles of social capital for the adaptation to climate change impacts on this small archipelago, which is representative of European small islands in an economically advanced, but isolated context. The Isles of Scilly are among the most vulnerable island regions in Europe. The results of the research contribute to the general discussion on social capital and the relevance of collective action for the adaptation to global climate change. How useful is the concept? And how relevant is it for small islands, such as the Isles of Scilly? [ABSTRACT FROM AUTHOR]

Symptoms of illness provide information about an organism's underlying state. This notion has inspired a burgeoning body of research on organisms' adaptations for detecting and changing behavior toward ill individuals. However, little attention has been paid to a likely outcome of these dynamics. Once an organism's fitness is affected by others' responses to symptoms of illness, natural selection can favor individuals who alter symptom expression to influence the behavior of others. That is, many symptoms may originate as cues, but will evolve into signals. In this paper, I develop the hypothesis that symptoms of illness serve signaling functions, and provide a comprehensive review of relevant evidence from diverse disciplines. I also develop novel empirical predictions generated by this hypothesis and discuss its implications for public health. Signaling provides an ultimate explanation for otherwise opaque aspects of symptom expression, such as why symptoms fluctuate in social contexts, and can exist without underlying pathology, and why individuals deliberately generate symptoms of illness. This analysis suggests that signaling theory is a major organizing framework for understanding symptom etiology. [ABSTRACT FROM AUTHOR]

For decades, many Australian coastal communities have been changing, in varying degrees, from traditional "fishing towns" to "mining", "tourism", or "retirement" towns. However, environmental changes, such as climate change, have increased the vulnerability of these communities and their capacity to continue to successfully adapt is unknown. A framework for the assessment of socio-ecological vulnerability is used to provide information on the response to change in Geraldton, Western Australia. Geraldton has traditionally been a port and fishing town and has recently become a hub for the expanding mining industry. An innovative historical assessment of adaptive capacity using sustainable livelihoods analysis with indicators of social, economic, human, financial, physical, and natural capital is used to calculate socio-ecological vulnerability over time. The framework integrates adaptive capacity with environmental change, resource dependence, and the socio-economic importance of the fished species during four census years: 1921, 1954, 1981, and 2011. The earlier years are characterized by high adaptive capacity and low socio-ecological vulnerability in keeping with strong economic growth and low unemployment rates following the First and Second WorldWars. The years 1981 and 2011 showed markedly higher socio-ecological vulnerability and lower adaptive capacities. This result was due to progressively greater exposure to climate change and the high socio-economic importance of fished species, as well as relatively poor physical, social, and natural capital. With continuing environmental and economic change, the fishing industry and the broader Geraldton population is likely to become increasingly vulnerable. Proactive rather than passive adaptation mayspeed the recovery and reduce a decline in the fishing industry and local economies. The paper briefly discusses potential adaptation in Geraldton which may be useful as a guideline for other coastal communities. [ABSTRACT FROM AUTHOR]

Adaptation, as a strategy to respond to climate change, has limits: there are conditions under which adaptation strategies fail to alleviate impacts from climate change. Research has primarily focused on identifying absolute bio-physical limits. This paper contributes empirical insight to an emerging literature on the social limits to adaptation. Such limits arise from the ways in which societies perceive, experience and respond to climate change. Using qualitative data from multi-stakeholder workshops and key-informant interviews with representatives of the fisheries and tourism sectors of the Great Barrier Reef region, we identify psycho-social and structural limits associated with key adaptation strategies, and examine how these are perceived as more or less absolute across levels of organisation. We find that actors experience social limits to adaptation when: i) the effort of pursuing a strategy exceeds the benefits of desired adaptation outcomes; ii) the particular strategy does not address the actual source of vulnerability, and; iii) the benefits derived from adaptation are undermined by external factors. We also find that social limits are not necessarily more absolute at higher levels of organisation: respondents perceived considerable opportunities to address some psycho-social limits at the national-international interface, while they considered some social limits at the local and regional levels to be effectively absolute.

Adaptation pathways are increasingly being used as a foresight tool to help guide the implementation of climate change adaptation and deliberate transformation. This paper applies a pathways lens as a hindsight tool to provide new understanding about past change and adaptation relevant for improving future adaptation pathways approaches. Four case studies of past adaptations to change are examined: Solomon Islands Communities, Canadian forest-dependent communities, a Transylvanian village, and responses to climate adaptation policies in Australia. The results highlight that responses to change in these diverse case studies involve complex transitions that gradually create new conditions and trajectories; manifest as multiple but inter-related pathways of change and response at different social or spatial scales (e.g. different paths for different households or communities); have legacies and continuities across time that affect future pathways of change; are affected by power in complex ways; and can create further change and need for adaptation. Analyses also highlight that when working with prospective adaptation approaches as a response to climate change there is a need to consider: (1) underlying assumptions, values and principles associated with the future; (2) the existence of inter-connected multiple pathways and their implications for reinforcing existing social inequalities; and (3) how understanding past change provides inspiration for new and transformative futures. Overall, the paper concludes that shifts towards analyses for change rather than simply about change, such as adaptation pathways, will require more careful consideration of underlying ontological assumptions about the relationships between past, present and future.

This paper explores vulnerability and adaptive capacity of rural communities in Southern Laos, where households are highly dependent on climate-sensitive natural resources and vulnerable to seasonal weather fluctuations. The speed and magnitude of climate-induced changes may seriously challenge their ability to adapt. Participatory group discussions and 271 household surveys in three villages highlight the current level of vulnerability and adaptive capacity towards climatic variability and risks. This paper visualizes three dimensions of the vulnerability framework at two levels using the Community Climate Vulnerability Index and household climate vulnerability cube. Results show that not only poor households are most at risk from climate change challenges, but also those better-off households highly dependent on specialized agricultural production are locally exposed to climate change risks. The majority of vulnerable households are characterized by low adaptive capacity. Floods and drought regularly put the poor under stress, which has led to various coping mechanisms; but capability of applying long-term adaptive strategies remains low among all households. The outcome of the participatory consultation underlines local community preference for an integrated approach to mainstream climate change adaptation into community natural resource management and livelihood improvement that may lead to better adaptive capacity building.

The Trent-Severn Waterway in central Ontario, Canada, is a large inland water system. It is managed for a broad range of stakeholders with different needs and expectations, creating a complex management context. Although variations in water levels occur, extreme low water-level events may increase in the future due to climate change, challenging management practices, in addition to requiring adaptation to reduce impacts. A modified policy Delphi was used to generate and evaluate ideas related to historical and future water-level impacts and adaptations. The paper presents the perspectives of three groups-cottagers and homeowners (CH), government (G), and industry and business (IB)-on their experiences with historic low water-levels, as well as their perspectives on future impacts and adaptations using two water-level scenarios: a moderate decrease of 25 cm and a more severe 50 cm decline. Shared impacts and adaptations (individual and collective) were identified along with those that were unique to a group. The likelihood of and consensus on potential impacts and most adaptations increased with the severity of water-level reduction. All groups indicated a higher likelihood of using collective rather than individual adaptations with the severe scenario, and in some cases, their contacts for assistance with adaptation broadened. While the modified policy Delphi requires significant effort by the analyst and respondents, it provides a useful framework for generating and analyzing perceptions and preferences of diverse stakeholders.

The present paper provides a reflection on threats to integrated management of the Thau coastal lagoon due to climate change and the multi-scalar water scarcity adaptation strategy. This study proposes first to depict the Thau water governance assessed through a water use and social network analysis and its capacity to manage water quality. Next, this paper provides a downscaled study on the climate change impacts on the hydrological budget of the entire Thau catchment in 2041–2070 compared with the 1971–2000 reference period, a methodology developed during the CLIMB EU research program. Following local climate change impacts, the importation of a new water resource to secure water uses is presented in regards to the capacity of local water governance to maintain coherence between integrated land planning and integrated water management planning based on water quality issues of the Thau coastal lagoon. The study underlines that although the water uses are currently secured thanks to the regional transfer of water, they are not coherent with local water management and create new vulnerabilities in the context of climate change. Moreover, the regional decision to end financial support for the more efficient, existing network for the water quality survey of regional coastal lagoons breaks up the local water governance. This paper demonstrates why keeping this network would have been absolutely necessary for encouraging a governance capable of proposing sustainable solutions to water quality challenges induced by climate change.

Vulnerability assessments (VAs) have been widely used to understand the risks posed by climate change and identify opportunities for adaptation. Few studies, however, have evaluated VAs from the perspective of intended knowledge users or with reference to established best practices. In this paper, we identify and evaluate VAs focusing on the built environment in northern Canada. We document 16 completed VAs, which range from engineering-based studies of the vulnerability of specific infrastructural assets (e.g. building foundations, roads) to community-based assessments characterizing the vulnerability of the built environment in general in specific communities. We then evaluate projects based on the extent to which they incorporate best practices for vulnerability assessment, informed by a review of the scholarship and interviews with practitioners and knowledge users in the north ( n = 21). While completed VAs have increased our understanding of the risks posed by climate change, none perform well across all evaluation criteria, and interviewees identified the need for improvement to VAs to inform decision making. Specifically, there is a need for greater emphasis on stakeholder engagement and effective communication of research findings, and interdisciplinary collaboration to capture the multiple drivers of vulnerability, cost impacts, and examine the performance of infrastructural assets under different climate scenarios.

This paper presents results from case studies in which we investigate the interrelations between changes in ecosystem services (ESs) and adaptive capacity among small-scale users of multi-use forest or outfields resources in northern Sweden and Norway. The study presents a framework that utilizes scenarios for changes in ESs under climate change in combination with qualitative interviews with outfield resource users in order to assess their adaptive capacity to the projected changes. The study illustrates that ESs may change significantly under climate change, and in particular affect winter snow and ice conditions, for instance increasing the duration of the growing season but with consequences for pasture quality. We find that given structural constraints, the key factors that influence the selected resource users’ adaptive capacity at an individual level include motivation and entrepreneurial inclinations, which are related to the lifestyle choice of making a livelihood based on small-scale and multi-use occupations.

Species often encounter, and adapt to, many patches of similar environmental conditions across their range. Such adaptation can occur through convergent evolution if different alleles arise in different patches, or through the spread of shared alleles by migration acting to synchronize adaptation across the species. The tension between the two reflects the constraint imposed on evolution by the underlying genetic architecture versus how effectively selection and geographic isolation act to inhibit the geographic spread of locally adapted alleles. This paper studies the balance between these two routes to adaptation in a model of continuous environments with patchy selection pressures. We address the following questions: How long does it take for a novel allele to appear in a patch where it is locally adapted through mutation? Or, through migration from another, already adapted patch? Which is more likely to occur, as a function of distance between the patches? What population genetic signal is left by the spread of migrant alleles? To answer these questions we examine the family structure underlying migration–selection equilibrium surrounding an already adapted patch, treating those rare families that reach new patches as spatial branching processes. A main result is that patches further apart than a critical distance will likely evolve independent locally adapted alleles; this distance is proportional to the spatial scale of selection (, where σ is the dispersal distance and sm is the selective disadvantage of these alleles between patches), and depends linearly on log(sm/μ), where μ is the mutation rate. This provides a way to understand the role of geographic separation between patches in promoting convergent adaptation and the genomic signals it leaves behind. We illustrate these ideas using the convergent evolution of cryptic coloration in the rock pocket mouse, Chaetodipus intermedius, as an empirical example. [ABSTRACT FROM AUTHOR]

Extreme sea levels and floods are a widespread threat to coastal communities, and sea-level rise is increasing the probability of such events. This paper describes how inundation modelling was used to engage local stakeholders about climate change and adaptation, for a town (Yarmouth) on the UK south coast. This included a participatory visualisation exercise using three extreme sea level scenarios, informed by a recent flood event. Further analysis, informed by the repeated floods during the 2013/14 storm surge season, placed these scenarios in a broader perspective across a range of events. Results indicate that coastal flooding may become a significant issue during this century due to sea-level rise, unless there is adaptation. These methods engaged the interest of the community, and this paper presents practical considerations for future studies. A similar approach could be applied widely at the community level and form an important component of coastal flood management, including planning responses to sea-level rise. [ABSTRACT FROM AUTHOR]

Dispersal through space or time (via dormancy) determines gene flow and influences demography. Because of their functional similarities, a covariation between dispersal and dormancy is expected. Dispersal and dormancy are anatomically linked in plants, because they both depend on attributes of the seed, albeit this anatomical association is rarely considered when analyzing interactions between dispersal and dormancy. In this paper, we investigate the extent to which dispersal and dormancy can be expected to correlate and how each might influence adaptation to novel environments such as those brought on by climate change. We review the theoretical and empirical literature on the subject with a focus on seed plants. We find that although a negative correlation between dispersal and dormancy has been theoretically anticipated, several models predict deviations from this expectation under scenarios of environmental heterogeneity. The empirical evidence does not support any specific covariation pattern, likely because the interaction between dispersal and dormancy is affected by multiple environmental and developmental constraints. From a climate change perspective, the effects of dispersal and dormancy on population structure are not equivalent: dormancy-mediated gene flow is intrinsically asymmetric (from the past towards the future) whereas spatial dispersal is not necessarily directional. As a result, selection on traits linked to dormancy and dispersal might differ qualitatively. In particular, gene flow through dormancy can only be adaptive if future environmental conditions are similar to those of the past, or if it contributes to novel allelic combinations. We conclude that, in spite of a long tradition of research, we are unable to anticipate a universal relationship between dispersal and dormancy. More work is needed to predict the relative contributions of spatial dispersal and dormancy to gene flow and adaptation to novel environments. [ABSTRACT FROM AUTHOR]

Fifty years after Ehrlich and Raven's seminal paper, the idea of co-evolution continues to grow as a key concept in our understanding of organic evolution. This concept has not only provided a compelling synthesis between evolutionary biology and community ecology, but has also inspired research that extends beyond its original scope. In this article, we identify unresolved questions about the co-evolutionary process and advocate for the integration of co-evolutionary research from molecular to interspecific interactions. We address two basic questions: (i) What is co-evolution and how common is it? (ii) What is the unit of co-evolution? Both questions aim to explore the heart of the co-evolutionary process. Despite the claim that co-evolution is ubiquitous, we argue that there is in fact little evidence to support the view that reciprocal natural selection and coadaptation are common in nature. We also challenge the traditional view that co-evolution only occurs between traits of interacting species. Co-evolution has the potential to explain evolutionary processes and patterns that result from intra- and intermolecular biochemical interactions within cells, intergenomic interactions (e.g. nuclear-cytoplasmic) within species, as well as intergenomic interactions mediated by phenotypic traits between species. Research that bridges across these levels of organization will help to advance our understanding of the importance of the co-evolutionary processes in shaping the diversity of life on Earth.

Pathways of adapting the built assets for future risk reduction are highly uncertain because of changes in socio-economic trends and climate. To provide solid foundation for better adaptation planning, this paper presents a statistical approach to investigate the future direct damage loss and the benefit of adaptation through elevating building floors of residential and commercial buildings affected by storm-tide hazard and sea-level rise in South East Queensland, Australia, particularly the implication of different extents of adaptation to policies. Because of projected socio-economic growth, it was found that, if considered separately, building stock growth causes twice as large as sea-level rise does to the potential damage loss. Adaptation by elevating new buildings alone is more cost-effective and socially acceptable than by elevating both new and old buildings. It is concluded that even with limited adaptation, immediate but less long-term net benefits could be achieved by focusing adaptation on the most vulnerable coastal housing. Somewhat pre-emptive adaptation that lifts more coastal housing in wider coastal area in the immediate term to accommodate future storm tides gives longer-term net benefits, though incurs higher adaptation costs. However, too much over-adapting may be undesirable as it incurs unreasonably high initial and on-going costs while the benefits of it could only be reaped over unrealistically long time. Geographical extent of asset adaptation should be decided in accordance with the planning time horizon to avoid either under- or over-adaptation. [ABSTRACT FROM AUTHOR]

Institutional responses to climate change stresses through planning will require new and amended forms of governance. Institutional framing of change imperatives can significantly condition associated governance responses. This paper builds on scholarly conversations concerning the conceptual role of ‘storylines’ in shaping institutional responses to climate change through governance. I draw on conceptual perspectives of climate change as a ‘transformative stressor’, which can compel institutional transformation within planning. The concepts of storylines and transformative stressors are conceptually linked. The conceptual approach is applied to an empirical enquiry focused on the regional planning regime of South East Queensland (SEQ), Australia. In this paper I report on and examine three institutional storylines of responding to climate change through planning governance in SEQ. I conclude that the manifestation of climate change as a transformative stressor in SEQ prompted institutional transformation, leading to a dominant storyline focused on climate adaptation as an important facet of regional planning governance.

For over two decades, municipal climate progress has been inventoried and analysed using a common reporting framework. While useful for highlighting the extent of municipal engagement in greenhouse gas mitigation efforts, we know little about how comprehensive this reporting framework is. Are municipal governments engaging in mitigation activities outside this framework? And what about climate adaptation activity for which no long-standing milestone reporting framework has existed? Based on results from a national survey of municipal governments in Canada, the paper reveals that municipal governments are engaged in many climate activities and processes that common inventories and reporting systems do not capture. The paper argues that these ‘in between activities’ – the not-yet counted climate actions that take place between and outside of milestone initiation and completion – have practical importance for future climate action and theoretical importance by complementing growing evidence about the nature of municipal climate activities and climate governance.

Climate change will result in large challenges that require societies to adapt to and manage increased risks. Regional practices of climate adaptation often take shape within multilevel governance networks in which representatives of different levels of government, policy sectors, public and private parties may discuss and negotiate potential measures. This paper aims to explore the role of leadership in enhancing the adaptive capacity of multilevel governance networks and in supporting regional practices of climate adaptation. The paper reviews two initiatives toward climate adaptation, the WaalWeelde initiative in the Netherlands and the Manhood Peninsula Partnership in the UK, based on policy documentation and analysis of in total 17 semistructured interviews with public and private actors. The study illustrates both the large differences in organization of water management, spatial planning, and flood risk policies, as well as strong similarities in the way in which leadership may contribute to the development of initiatives.

Climate change adaptation is one of the many development challenges impacting livelihoods in developing countries. Scenario approaches are useful in adaptation planning by putting together projected climate change and socioeconomic trends with broader development needs when identifying associated priorities-and using them to develop appropriate strategies, plans and initiatives. To date, explorative scenario approaches have been largely adopted in adaptation planning. In this paper, we determine the benefits of using normative scenario approaches. They include a process known as 'backcasting,' which is particularly useful for areas where adaptation planning and actions are strongly intertwined with development planning, and considerable efforts are needed to improve the well-being of the people living in those areas. We show the relevance of backcasting by presenting three case study applications in the following developing countries: Ghana, Honduras and Tajikistan. The results of these case studies indicate that backcasting has specific relevance for adaptation planning, including capacity building and awareness raising to contextualize information on climate impacts with stakeholders' development needs. Our results also indicate that the developed scenarios provided benefits in promoting horizontal and vertical integration, thus bringing together diverse sectorial and sub-national priorities-adaptation options can thereby be aligned with these needs. Finally, use of the scenarios advances countries' participation in national and multi-country adaptation projects by targeting actions that provide multiple benefits. [ABSTRACT FROM AUTHOR]

Dexterous action, as conceptualized by Bernstein in his influential ecological analysis of human behavior, is revealed in the ability to flexibly generate behaviors that are adaptively tailored to the demands of the context in which they are embedded. Conceived as complex adaptive behavior, dexterity depends upon the qualities of robustness and degeneracy, and is supported by the functional complexity of the agent-environment system. Using Bernstein's and Gibson's ecological analyses of behavior situated in natural environments as conceptual touchstones, we consider the hypothesis that complex adaptive behavior capitalizes upon general principles of self-organization. Here, we outline a perspective in which the complex interactivity of nervous-system, body, and environment is revealed as an essential resource for adaptive behavior. From this perspective, we consider the implications for interpreting the functionality and dysfunctionality of human behavior. This paper demonstrates that, optimal variability, the topic of this special issue, is a logical consequence of interpreting the functionality of human behavior as complex adaptive behavior.

Enzymatic reactions of post-synthetic modification of macromolecules occur in the cells of all organisms. These reactions, which can be designated as epibiochemical, are of a special type and, as discriminated from reactions with low molecular weight substrates, occur on the level of biopolymers, causing their covalent modification. The majority of epibiochemical modifications of proteins, DNA, and RNA are reversible and are carried out by modification transferases and demodification enzymes, respectively. Epibiochemical, i.e. those located above the low molecular weight metabolites, modifications of proteins and nucleic acids perform various functions, including participation in molecular mechanisms of adaptive epigenetic heredity. This paper presents an overview of some adaptive epibiochemical modifications of macromolecules and the adaptive epigenetic processes on their basis. The features of epigenetic inheritance of acquired characteristics and the limits of biological evolution are discussed. [ABSTRACT FROM AUTHOR]

Where power lies and how it is conceived in studies of governance and institutions is often not discussed. This is due to the ubiquitous nature of the topic. Power is shaped by a variety of institutional factors, including the architecture of governing structures, questions of scale and level, and access to key resources including knowledge and capital, among other factors. To date, there are relatively few tools available that allow policy makers, researchers, and development practitioners to render these power dynamics explicit and thus take steps to mitigate the potentially deleterious effects of power orientations. This paper proposes a methodology, multi-level stakeholder influence mapping (MSIM), for elucidating power dynamics between actors in complex system regimes. MSIM departs from existing power mapping techniques in that it relies on individual interviews conducted across multiple actor levels and utilizes a participatory mapping process for shared system boundary critique. MSIM was piloted in Nepal's agricultural climate change adaptation regime with actors from the central, regional, and local operational levels. The results suggest that without proper consideration of the role of power in agricultural adaptation regimes, the resulting interventions will likely be insufficient in catalyzing adaptation pathways and moderating the negative impacts of climate change. Furthermore, power analyses produced from the perspective of a single actor level or respondent type can risk sub optimization of adaptation outcomes and can misdirect the lobbying efforts of those agencies utilizing mapping outputs.

This paper describes an interdisciplinary approach towards a framework for personalized, game-based training programs for elderly and handicapped people. Adaptation and personalization are proposed as a way to increase the physiological training effects of game-based training programs (exergames). Hereby, the diversity of users and a broad range of physiological handicaps are considered. The framework is based on scientific training programs enhanced by technical methods and concepts for personalized exergames. This includes an authoring environment (StoryTec) which supports game designers and domain experts (sport scientists, medical doctors, therapists, etc.) in the development process and the (personalized) configuration of such exergames. Two prototypically implemented applications (ErgoActive and BalanceFit) demonstrate the usability and adaptation of the underlying training and game concepts for different user groups and provide indicators of the effectiveness and efficiency of the generic framework for particular user groups. For instance, ErgoActive is applicable for people of all ages and both trained and untrained users by being able to provide personalized training levels to improve endurance. Similarly, BalanceFit is useful both for wheelchair and walking frame users in order to maintain and possibly even increase their balance, strength and muscular coordination. [ABSTRACT FROM AUTHOR]

Clinical trial adaptation refers to any adjustment of the trial protocol after the onset of the trial. Such adjustment may take on various forms, including the change in the dose of administered medicines, the frequency of administering an intervention, the number of trial participants, or the duration of the trial, to name just some possibilities. The main goal is to make the process of introducing new medical interventions to patients more efficient, either by reducing the cost or the time associated with evaluating their safety and efficacy. The principal challenge, which is an outstanding research problem, is to be found in the question of how adaptation should be performed so as to minimize the chance of distorting the outcome of the trial. In this paper we propose a novel method for achieving this. Unlike most of the previously published work, our approach focuses on trial adaptation by sample size adjustment i.e. by reducing the number of trial participants in a statistically informed manner. We adopt a stratification framework recently proposed for the analysis of trial outcomes in the presence of imperfect blinding and based on the administration of a generic auxiliary questionnaire that allows the participants to express their belief concerning the assigned intervention (treatment or control). We show that this data, together with the primary measured variables, can be used to make the probabilistically optimal choice of the particular sub-group a participant should be removed from if trial size reduction is desired. Extensive experiments on a series of simulated trials are used to illustrate the effectiveness of our method. [ABSTRACT FROM AUTHOR]

This paper studies morphometric parameters (body weight, weight of internal organs, body size, etc.) in 170 elk of various sex and age obtained in the Vyatka taiga area in winter. A number of physiological parameters (specific metabolism and thermal conductivity, heat loss rate, etc.) characterizing the metabolic rate and energy balance in the body were calculated for model animals (calf, male, and female). It is noted that in the transition from the first to the second half of winter the specific metabolism in model animals decreased from 20.6, 16.9, and 15.9 to 18.7, 15.4, and 14.5 kcal/(kg day), respectively. It is shown that changes in the rhythm of motor activity of elk are synchronized with the daily air temperature and the maximum flight distance depends on the amount of energy received by the body with food.

Increases in atmospheric CO2 concentration have exerted significant impacts on plant growth. Numerous studies have reported positive effects of elevated CO2 on plant growth and adaptation to various environmental stresses in many plant species. The mechanisms by which CO2 enrichment regulates plant growth and stress adaptation are not completely understood. There have been some recent exciting advances in elucidating the cellular, metabolic, and molecular basis for increased growth under elevated CO2. At the cellular level, cell growth involving both cell division and cell expansion is stimulated by increasing CO2, which has been associated with increased photosynthetic activities and carbohydrate availability, and also with the expression of genes controlling cell division, cycling, and cell expansion. Proteomic profiling studies identified CO2-regulated proteins mainly involved in photosynthesis, carbon metabolism, energy pathways, molecular chaperones, and antioxidant proteins. Transcriptomic analyses identified several hundreds of genes responsive to elevated CO2 levels, which play roles in cell wall loosening, photosynthesis, respiration, water use, and protein synthesis, as well as stress defense. This paper reviews recent progress in the mechanistic understanding of CO2 regulation of plant growth and stress adaptation at the cellular, metabolic, and molecular levels, and addresses research gaps and future research perspective areas.

Combining evolutionary games with adaptive networks, an entangled model between strategy evolution and structure adaptation is researched in this paper. We consider a large population of cooperators C and defectors D placed in the networks, playing the repeated prisoner׳s dilemma (PD) games. Because of the conflicts between social welfare and personal rationality, both strategy and structure are allowed to change. In this paper, the dynamics of strategy originates form the partner imitation based on social learning and the dynamics of structure is driven by the active linking and neighbourhood reaction. Notably, the neighbourhood reaction is investigated considering the changes of interfaces between cooperators and defectors, where some neighbours may get away from the interface once the focal agent changes to different strategy. A rich landscape is demonstrated by changing various embedding parameters, which sheds light upon that reacting promptly to the shifted neighbour will promote the prevalence of cooperation. Our model encapsulates the dynamics of strategy, reaction and structure into the evolutionary games, which manifests some intriguing principles in the competition between two groups in natural populations, artificial systems and even human societies.

The Development & Climate Days held at the United Nations Framework Convention on Climate Change (UNFCCC) Conference of Parties (COP) 19 in Warsaw, Poland (16–17 November 2013) continued its tradition of bringing together a diverse range of experts for intensely participatory learning, dialogue and networking. This event convened over 200 negotiators, policy-makers, scientists, funding agencies and development practitioners. The highly interactive, out-of-the-box programme featured ‘Lightning Talks’, a new experiential learning game about loss and damage, and a session on ‘Challenges and Innovations from the Field’. Each of these sessions aimed to foster an environment of collaboration among participants and inject serious fun into the climate and development dialogue processes. This paper introduces some of the participatory tools and methods applied by the Global Environment Facility and the Climate Centre during the Day 1 programme and considers their effectiveness in serving the purpose of the event. The paper identifies key success factors and limitations with a view to informing the design of future events that may seek to apply new methods for eliciting dialogue and promoting peer-to-peer learning between diverse stakeholders.

Evolutionary psychology is among the various evolutionary and cognitive perspectives that have been used to account for the origins of art. It sets out to explain modern human psychology by means of the evolutionary history of the species, and by determining why and how our extant cognitive machinery evolved as adaptations to past environmental surroundings or by-products of such adaptations. In the case of art, evolutionary psychologists seek to track down its cognitive foundations and establish its evolutionary rationale, for instance by determining which function artistic behaviour as a whole might have performed. However, several methodological issues and gaps currently impede evolutionary psychological research on art: empirical support is often lacking, adaptationist claims are not adequately substantiated, and the definition and scope of basic aspects of evolutionary psychology often remain underspecified. This paper reviews the central themes that evolutionary psychology currently advances to account for the emergence of visual arts, music and fiction, addresses the most relevant methodological issues, and provides some suggestions that might help to develop evolutionary research on art.

Whether music was an evolutionary adaptation that conferred survival advantages or a cultural creation has generated much debate. Consistent with an evolutionary hypothesis, music is unique to humans, emerges early in development and is universal across societies. However, the adaptive benefit of music is far from obvious. Music is highly flexible, generative and changes rapidly over time, consistent with a cultural creation hypothesis. In this paper, it is proposed that much of musical pitch and timing structure adapted to preexisting features of auditory processing that evolved for auditory scene analysis (ASA). Thus, music may have emerged initially as a cultural creation made possible by preexisting adaptations for ASA. However, some aspects of music, such as its emotional and social power, may have subsequently proved beneficial for survival and led to adaptations that enhanced musical behaviour. Ontogenetic and phylogenetic evidence is considered in this regard. In particular, enhanced auditory-motor pathways in humans that enable movement entrainment to music and consequent increases in social cohesion, and pathways enabling music to affect reward centres in the brain should be investigated as possible musical adaptations. It is concluded that the origins of music are complex and probably involved exaptation, cultural creation and evolutionary adaptation. [ABSTRACT FROM AUTHOR]

Climate change will further exacerbate wetland deterioration, especially in the Mediterranean region. On the one side, it will accelerate the decline in the populations and species of plants and animals, this resulting in an impoverishment of biological abundance. On the other one, it will also promote biotic homogenization, resulting in a loss of species' diversity. In this context, different climate change adaptation policies can be designed: those oriented to recovering species' abundance and those aimed at restoring species' diversity. Based on the awareness that knowledge about visitors' preferences is crucial to better inform policy makers and secure wetlands' public use and conservation, this paper assesses the recreational benefits of different adaptation options through a choice experiment study carried out in S'Albufera wetland (Mallorca). Results show that visitors display positive preferences for an increase in both species' abundance and diversity, although they assign a higher value to the latter, thus suggesting a higher social acceptability of policies pursuing wetlands' differentiation. This finding acquires special relevance not only for adaptation management in wetlands but also for tourism planning, as most visitors to S'Albufera are tourists. Thus, given the growing competition to attract visitors and the increasing demand for high environmental quality and unique experiences, promoting wetlands' differentiation could be a good strategy to gain competitive advantage over other wetland areas and tourism destinations.

In this paper, we propose a game adaptation technique that seeks to improve the training outcomes of stroke patients during a therapeutic session. This technique involves the generation of customized game levels, which difficulty is dynamically adjusted to the patients' abilities and performance. Our goal was to evaluate the effect of this adaptation strategy on the training outcomes of post-stroke patients during a therapeutic session. We hypothesized that a dynamic difficulty adaptation strategy would have a more positive effect on the training outcomes of patients than two control strategies, incremental difficulty adaptation and random difficulty adaptation. To test these strategies, we developed three versions of PRehab, a serious game for upper-limb rehabilitation. Seven stroke patients and three therapists participated in the experiment, and played all three versions of the game on a graphics tablet. The results of the experiment show that our dynamic adaptation technique increases movement amplitude during a therapeutic session. This finding may serve as a basis to improve patient recovery.

This paper applies a systematic approach to measuring adaptation actions being undertaken by 117 parties to the United Nations Framework Convention on Climate Change (UNFCCC) with the goal of establishing a baseline of global trends in adaptation. Data are systematically collected from National Communications prepared by Parties to the Convention and submitted periodically to the Secretariat. 4,104 discrete adaptation initiatives are identified and analyzed. Our findings indicate that while progress is being made on conducting impact and vulnerability assessments and adaptation research in nearly every country in the sample, translation of this knowledge into tangible adaptation initiatives is still limited. The largest number of reported adaptations falls under the category of infrastructure, technology, and innovation. Some types of vulnerability were more frequently reported across initiatives, including floods, drought, food and water safety and security, rainfall, infectious disease, and terrestrial ecosystem health. Notably, reporting on the inclusion of vulnerable sub-populations is low across all actions. Diffusion of adaptation across sectors remains underdeveloped, with the environment, water, and agricultural sectors emerging as the most active adaptors. Our analysis indicates that national communications provide a valuable source of information for global-scale adaptation tracking, but important gaps exist in the consistency of reporting that should be addressed, as these documents could greatly enhance efforts to monitor and evaluate adaptation progress.
