Research in the UK suggests that multi-componential interventions focusing on language and pre-literacy skills can improve children's reading and language skills. However, simple translations of such programmes may not produce equivalent effects in diverse communities. The reasons for this are multi-faceted and include factors beyond the rationale and content of the intervention programmes themselves. Understanding these factors is critical for creating programmes that will generalise across settings. In this review, we reflect upon challenges encountered in two reading and language intervention programmes in South America to identify community and cultural contextual factors that can influence the implementation and scalability of educational programmes. We use our findings to develop an education-specific framework to guide the development and implementation of high-quality evidence-based approaches to language and literacy intervention. Our model guides implementation practices in diverse contexts and stresses the importance of the evidence-base and communication.

This paper analyzes the activities, members, and effects of an inter-American expert network for the diffusion of psychometric knowledge, specifically of standardized aptitude testing for university admission in Latin America during the 1960s and 1970s. Within the framework of educational transfer studies, the role of international, nongovernmental, and philanthropic organizations is examined. It is argued that circulation of psychometric knowledge and technologies led to a new governing regime for learning and learners. The paper discusses the effect of convergence and Americanization, in the context of US-promoted "Alliance for Progress," but also of divergence and resistance.

This article synthesises findings from two systematic reviews that examined evidence of the link between large-scale assessments (LSAs) and education policy in economically developing countries and in countries of the Asia-Pacific. Analyses summarise evidence of assessment characteristics and policy goals of LSAs that influence education policy, when LSAs are used in the policy-making cycle and types of education policies impacted, and factors that influence the use of LSAs in policy-making. Results show national assessments conducted at both primary and secondary school levels to have an impact on education policy. LSAs are used more often for monitoring education quality and equity purposes followed by accountability purposes. International assessments are more often used to leverage policy priorities than other assessment types. LSAs feature mainly at the monitoring and evaluation stage of the policy cycle. The education policies impacted by LSAs relate considerably more to curricular reforms and performance standards as well as assessment bodies and activities and far less to resource allocation and teaching and learning policies. Finally, whereas the quality of assessment programmes facilitate impact, financial constraints and uncertainty as well as weak assessment bodies hinder the impact of LSAs on education policy.

Chile is one of the worst countries in Latin America in terms of urban air pollution. This situation negatively affects the health and well-being of Chileans. This paper uses a non-traditional valuation method, based on life satisfaction perception, to estimate citizens' willingness to pay (WTP) for the reduction of air pollution in Chilean cities. We consider the annual average of PM10 and PM2.5 for 70 municipalities, including the main urban areas. An objective measure of air pollution is linked to a subjective measure of life satisfaction by using the main survey of households in Chile for cross-sectional socioeconomic data. According to our knowledge, this is the first study of its kind in Latin American and, in the case of PM2.5 reductions, one of the first cases at the world level. We found that our estimation of WTP for reducing PM10 and PM2.5 emissions are significantly lower in Chilean cities than in most of the results found in the literature in other countries. However, when comparing this paper results to the ones from other Chilean studies, perspectives vary, e.g., our estimation of WTP for reducing MP10 is higher than one obtained when using the damage function approach but comparable to another obtained with the hedonic prices approach.

In the introduction to this special issue on Latin American housing policies, we address the common elements evident in this collection of papers with the aim of enabling a better knowledge exchange between the 'global North' and the 'global South' on potentially common issues. These include the changing relationship between state and capital, with special emphasis on the new role adopted by the State as a facilitator for financial private capital in an increasingly privatised housing sector; the need to address precarious housing conditions among vast sectors of the population, including international migrants; and the various innovative roles played by civil society in housing provision. Notwithstanding these similarities between world regions, our editorial introduction highlights a number of particularities in housing research in the Latin American region, underscoring the need to reflect critically on the applicability of concepts and models created in different geographical contexts with different historical, social and political realities. Within this editorial, we also introduce the main themes discussed in the specific articles and attempt to place them within the more general scope of earlier research on housing policies in the region. We conclude by acknowledging that a solution to long lasting housing inequality in Latin America remains an unfulfilled promise. [ABSTRACT FROM AUTHOR]

Inclusive recycling is the inspiring slogan of a project relying on a cross-sector (public–private–civil society) partnership implemented in Latin America with the objective to improve the socioeconomic conditions of recyclers. Through a qualitative study in Santiago de Chile, this paper seeks to understand how inclusive inclusive recycling is, by assessing how organised recyclers perceive the goals, the process, and the outcomes of this project. The main findings converge in observing a general low inclusion of recyclers, but they also enable to decompose the notion of inclusion into three dimensions: “inclusive goals” refers to the extent to which the goals of the recyclers are taken into account when designing the collaboration project; “inclusive process” refers to the extent to which recyclers are involved in the process of implementing the project; and “inclusive outcomes” refers to the capacity of the partnership to acknowledge the achievements of recyclers organisations before (and during) the project and to take into account the ongoing local dynamics when evaluating the project. These findings contribute to better understand the position and challenges of recyclers in this type of partnership and more generally to shed light on the potential power imbalance in waste management cross-sector partnerships.

The research objective is to explore Chile's entrepreneurial landscape by assessing individual characteristics and institutional factors through a 'pillars' framework and compare it against Colombia, and Brazil; to identify socioeconomic, individual, and institutional differences using the Global Entrepreneurship Index (GEI); to apply bottleneck approach to highlight areas requiring policy intervention. GEI features individual and institutional stage variables in a method where every variable collaboratively interacts, incorporating 14 foundational elements and three sub - indexes: attitudes, abilities, and aspirations. Ranking 18th on the GEI globally and the best in Latin America, Chile excels in key entrepreneurial pillars, showcasing strengths in innovation and a robust entrepreneurial culture. Brazil closely rivals Chile in competition and networking, emphasizing political and economic influence. Colombia surpasses Chile in internationalization and growth-stimulating policies but faces challenges like historical conflicts and wealth distribution. This study identified areas where immediate policy intervention may be necessary by examining Chiles's entrepreneurial ecosystem. The Penalty for Bottleneck (PFB) technique identif ied the weakest pillars highlighting process innovation, competition, and internationalization. The primary component identified as a bottleneck for resource allocation is Process Innovation, accounting for 73% of the allocation, followed by Competition at 23%. The findings show that allocating more resources to process innovation may improve greatly the overall GEI score. [ABSTRACT FROM AUTHOR]

While scholars and policy practitioners often advocate for science and technology transfer as a motor for economic growth, many in Latin America have long warned of the pitfalls of such top-down, North-South transfers. To many in Latin America, scientific aid or cooperation from the North has often reproduced hierarchies that perpetuate dependency. Large astronomy observatories located in Chile - with a high price tag, cutting-edge technology, and seen to answer seemingly arcane research questions - seem ripe for reproducing precisely these kinds of hierarchical relationships. Using data from documents, interviews, and a site visit to Gemini South, one of several large telescopes in Chile, this paper takes a historical perspective to examine how resilient these hierarchical relationships are. Over forty years, astronomy in Chile grew thanks to new policies that fostered cooperation among universities and gave locals privileged access to the telescopes. But the community also grew in ways that reproduced dependency: foreign science benefits significantly, the Chilean state operates in top-down ways, and its support for science leaves it blind to the benefits high-tech telescopes deliver to Chile, which are not linked to export-led growth. The state appears as both an obstacle and an enabler to the growth of a national scientific community. [ABSTRACT FROM AUTHOR]

Abstract Coastal tourism developed along the Valparaíso region of Chile is being threatened by a very particular issue: scenery degradation related to extreme urbanization and collateral effects. This paper presents the results of scenic evaluation of 96 sites along this region. The scenic evaluation assesses values from a checklist of 18 physical and 8 human parameters, and permits calculation of a scenic evaluation index (D Value), which classifies coastal sites into five classes: Class I, usually natural areas of top scenic characteristics, to Class V, poor scenic natural areas with a higher impact of human interventions. In summary, 14 sites (15%) appeared in Class I; 7 (7%) in Class II; 9 (9%) in Class III; 17 (18%) in Class IV and 49 sites (51%) in Class V. This evaluation provides a complete scenic assessment overview of the Valparaiso Region, allowing implementation of an adequate management strategy based on knowledge of coastal scenery for the maintenance and preservation of scenic quality. Highlights • The Valparaíso Region's coastline region is a popular crescent destination for many national and international tourists. • The Valparaíso region of Chile is being threatened by a very particular issue: scenery degradation. • Scenic assessment of 96 coastal sites located along the Valparaíso Region coastline (continental and insular). • Scenic evaluation assesses values from a checklist of 18 physical and 8 human parameters. • Urbanization, port development, shoreline retreat, and litter pollution are of particular note in the Valparaíso Region.

The tribe Astereae (Asteraceae) displays an American Amphitropical Disjunction. To understand the eco-evolutionary dynamics associated with a long-distance dispersal event and subsequent colonization of extratropical South America, we compared the climatic and geographic distributions of South American species with their closest North American relatives, focusing on the diverse South American Astereae genus, Haplopappus. Phylogenetic analysis revealed that two South American genera are closely related to seven North American genera. The climatic niche overlap (D = 0.5) between South and North America exhibits high stability (0.89), low expansion (0.12), and very low unfilling (0.04). The distribution of the North American species predicted the climatic and geographic space occupied by the South American species. In central Chile, Haplopappus showed a non-random latitudinal gradient in species richness, with Mediterranean climate variables mainly explaining the variation. Altitudinal patterns indicated peak richness at 600 m, declining at lower and higher elevations. These findings support climatic niche conservatism in shaping Haplopappus species distribution and diversity. Two major endemism zones were identified in central Chile and the southern region, with a transitional zone between Mediterranean and Temperate macro-bioclimates. Our results indicate strong niche conservatism following long-distance dispersal and slight niche expansion due to unique climatic variables in each hemisphere. [ABSTRACT FROM AUTHOR]

Simple Summary: Natural pearls of Diplodon chilensis, a freshwater clam native to southern South America, are reported and characterized for the first time. The finding also constitutes the first record of pearls in a species of the genus Diplodon. The pearls have different shapes and sizes, and were found in both, male and female specimens. The microstructure and chemical composition of pearls is consistent with those reported in other bivalve species. The capability to produce pearls is widespread in the phylum Mollusca, including bivalves of the superfamily Unionoidea. Here, we identified and characterized natural pearls formed by Diplodon chilensis, a freshwater clam native to southern South America, using samples obtained from two lakes located in the Chilean Patagonia. Pearls were studied using light and scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), Fourier transform infrared spectroscopy (FTIR), and Raman spectroscopy. Naturally formed pearls were found in both male and female D. chilensis specimens. Pearls are produced in different shapes, including spherical, ellipsoidal, buttoned, and bumpy, ranging in size from 200 µm to 1.9 mm. The internal microstructure is composed of irregular polygonal tablets, about 0.40 to 0.55 μm in thickness. EDX analysis showed that pearls are composed of calcium carbonate. FTIR and Raman spectra recorded several peaks attributable to the aragonite in pearls of this species, as has been shown in other mollusks. In addition to these results, pearls of different colors are illustrated. [ABSTRACT FROM AUTHOR]

This paper assesses the impact of the El Niño Southern Oscillation (ENSO) on the wind speed, energy production, as well as its impact on the value of potential wind projects at different sites across Chile. The study applies cyclostationary empirical orthogonal function (CSEOF) analysis to isolate the ENSO influence on the wind speed, and therefore on the energy output of nearly all current and potential wind farms in Chile. Finally, a review of techno-economical parameters is made to assess the economic impact of an ENSO event occurring at different years in the lifetime of a wind energy project. The main contribution of this work is to establish the locations in Chile where this climatic oscillation is important for the system planning, the energy forecasting and the risk assessment.

Since the mid‐20th century, the so‐called Great Acceleration (sensu Steffen et al., 2007, https://doi.org/10.1579/0044-7447(2007)36[614:TAAHNO]2.0.CO;2) has amplified processes of ecosystem degradation, extinction of biological species, displacement of local peoples, losses of languages, and cultural diversity. These losses are still underperceived by the academic community, and by a global society that is disconnected from biocultural diversity. To reconnect society with biocultural diversity, we integrate temporal and spatial dimensions of seasonal cycles, by combining two conceptual frameworks: ecological calendars and the "3Hs" model of the biocultural ethic (sensu Rozzi, 2012, https://doi.org/10.5840/enviroethics20123414). The latter values the vital links between human and other‐than‐human co‐inhabitants, their life habits (e.g., cultural practices of humans or life cycles of other‐than‐human species), and the structure and processes of their shared habitats. This integration enhances an understanding of links between cultural practices and the life cycles of biocultural keystone species. As a synthesis, we use the term biocultural calendars to emphasize their co‐constitutive nature that result from interactions between dynamic biophysical and cultural processes embedded in specific ecosystems and cultures. These calendars link astronomical, biological, and cultural seasonal cycles that sustain life and enhance the integration of Indigenous and scientific knowledge to confront challenges of climate change faced from local to global scales. To illustrate this integration, we examine cultural practices and socio‐environmental changes across four contrasting ethnolinguistic communities in southwestern South America, from southern to northern Chile along a marked climatic gradient to show the broad application of the concept of biocultural calendars. Plain Language Summary: We combine ecological calendars and the biocultural ethic. The first refers to natural or seasonal calendars and focuses on the temporal scale of life cycles and other ecological phenomena observed at a given place. The second emphasizes the vital links among human and non‐human co‐inhabitants, their habits (e.g., cultural practices of humans or life cycles of other‐than‐human species) in shared habitats (the "3Hs" of the biocultural ethic). Close observation of biological and cultural diversity, and their interrelationships (in short, biocultural diversity), synchronizes cultural practices with natural processes at specific places. This synchrony is particularly relevant in the context of climate change because by being locally attuned, communities enhance their capacity to adapt their activities to the variability of temperature, rainfall, and other climatic events. In this article we use the term biocultural calendars to more closely understand the links between different life habits in contrasting habitats and annual seasons. In this way, biocultural calendars provide an understanding of biological and cultural heterogeneity in different seasons and regions of the world that can help us adapt to a rapidly changing world. Key Points: Biocultural calendars are co‐constitutively generated through interactions between dynamic biophysical and cultural processesThe biocultural ethic's 3Hs model values the vital links among human and other‐than‐human co‐inhabitants, their habits, and shared habitatsBiocultural calendars are based on seasonal cycles of keystone species that are part of communities of co‐inhabitants [ABSTRACT FROM AUTHOR]

Simple Summary: Triatomines are hemimetabolous and hematophagous insect vectors of Trypanosoma cruzi, the parasite that causes Chagas disease. The life cycle of triatomines is composed of five nymphal stages and an adult stage. The wild kissing bug Mepraia spinolai is distributed in a vast area of the semiarid Mediterranean ecosystem of South America, characterized by strongly marked seasons. The population structure of this vector changes during the different seasons, suggesting its development is controlled under natural conditions. In this study, we performed a biological assay to study this vector development after two laboratory feedings. We collected nymphs, first to fourth instars, in eight M. spinolai populations during the transition of late fall to winter (cooling period) and spring (warming period) of three consecutive years. The gathered information with vectors molting twice suggests that development is differentially controlled in nymphs from first and fourth instars depending on the climatic period of collection. Additionally, T. cruzi infection changes development forward only in nymphs of second and fourth instars of the warming period. Our findings suggest that the effect of the climatic period and T. cruzi infection on the development of this vector species is a stage-dependent phenomenon. In this study, we evaluated the effect of the climatic season and infection by Trypanosoma cruzi, etiological agent of Chagas disease, on the molting capacity of the triatomine vector Mepraia spinolai endemic to Chile. We used wild-caught first-to-fourth instar nymphs during cooling (fall and winter) and warming (spring) periods. After capturing, nymphs were fed at the laboratory, and maintained under optimal rearing conditions. Feeding was repeated 40 days later. We followed-up the molting events on 709 nymphs, recording one, two or the absence of molts after two feeding opportunities. Within the same climatic period, only infected second- and fourth-instar nymphs from the warming period showed a larger proportion of double molting compared to uninfected nymphs. Regarding the climatic period, infected and uninfected first- and fourth-instar nymphs exhibited a larger proportion of double molting in the warming and cooling periods, respectively. The pattern of non-molting nymph occurrence suggests they probably reach diapause by environmental stochasticity. The effect of the climatic period and T. cruzi infection on the development of M. spinolai is an instar-dependent phenomenon, highlighting the occurrence of finely synchronized processes at different moments of the life cycle of such an hemimetabolous insect as triatomines.

Purpose: This empirical study examines the drivers of consumer intention to adopt wearable technology for healthcare in a South American country. Specifically, it proposes and tests a model of nonuser consumer intention to adopt fitness trackers for healthcare purpose in Chile. Design/methodology/approach: This study draws on the technology acceptance framework UTAUT2 to develop and test a conceptual model of wearable technology adoption. Data were collected through an online survey applied to 470 nonusers of wearable technology in Santiago, Chile. Findings: Findings indicate that hedonic motivation, social influence and perceived usefulness have the strongest influence on intention to adopt fitness trackers in Chile for healthcare. In addition, health motivation is an indirect predictor of consumer's intention to adopt wearable technology through its effect on perceived usefulness. Practical implications: The study contributes to a better understanding of consumer intention to adopt wearable technology for healthcare objectives in a less developed country in South America. Findings are useful for wearable technology managers, retail business and public policymakers. Originality/value: Despite the vast growth and importance of wearable technology for healthcare purposes, academic research considering less developed countries is scarce, especially the South American region. The proposed model and findings can extend this research gap. Theoretical and managerial implications are discussed as well as implications for public policy. [ABSTRACT FROM AUTHOR]

The fossil record of marine mammals from the upper Pliocene of the western coast of South America is poorly known, hindering our knowledge about how and when marine mammal faunas attained their modern distribution in the area. Here, we describe a new marine mammal assemblage from the Horcón Formation (upper Pliocene), located in the Valparaíso Region of central Chile. The material reported comprises postcranial remains of an indeterminate seal (Phocidae), Delphinoidea vertebrae, and mysticete elements (still in the field). The Phocidae remains constitute the youngest pre-Pleistocene record of this family in South America, providing new information regarding the timing for the establishment of the modern diversity and distribution of pinnipeds in the Southern Hemisphere. Furthermore, the pinniped and cetacean remains reported indicate that the marine mammal assemblage from the upper Pliocene along central Chile was composed of a mixture of modern and extinct taxa.

Azorella is a genus with 26 species of Azorelloideae (Apiaceae) that grow from Costa Rica to the subantartic islands, being distintive and dominant in different environments of the Andean Cordilleras from Venezuela to Patagonia. The species of Azorella that grow in Argentina have been revised taxonomically in a previous study. However, knowledge of the remaining species is fragmentary and uneven. The aim of this paper is to update and standardize the information of the 11 species of Azorella absent in Argentina and present in Bolivia, Chile, Colombia, Ecuador, Peru and/or Venezuela. We provide descriptions for those species and update distributional maps, and we solve nomenclatural and typification problems for 41 names, designating 2 type species, 16 lectotypes and 1 neotype. In addition, we provide 10 new illustrations, and an identification key for all the species of the genus. [ABSTRACT FROM AUTHOR]

The previously successful British merchant houses on the west coast of South America faced significant problems between the two world wars. Earlier historians have referred to difficulties such as the volatility of commodity prices, the organisation and structure of the firms, and changes in patterns of trade. This paper, instead, compares their different experiences on the basis of archives from the merchants and their banks, concluding that their response to crisis differed, depending on the manner and extent of diversification, their core expertise, the quality of their management, and the support of their banks. The outcomes varied from outright failure to continued growth, with the two largest firms struggling to survive and adapt to the new business environment. [ABSTRACT FROM AUTHOR]

In this paper, we analyze the role of engineering and research in the environmental licensing process in the light of institutional changes made in Chile since 2010: the creation of the Ministry of Environment and the Environmental Assessment Service. To do this, we will show the challenges posed by these new institutions, the opportunities identified and the work undertaken to address those changes. Finally, the results will be presented taking the Punta Alcalde project as a model. [ABSTRACT FROM AUTHOR]

This article analyzes the role of exploitable nature in the International Exhibition held in Chile in 1875. Based on documentation from the organization and development of the even such as letters, catalogs, newspapers and visitor reports the article examines first, the ways in which the countries' exploitable nature related to agriculture and mining was represented in this event. This paper looks to examine the base upon which objectives and models were exhibited, and at the same time examines how the representation of this nature could imply its denaturalization, by strictly presenting it as rational and almost artificial. Second the article analyzes how some parts of nature represented in the exhibition could have been appropriated, at least provisionally, within national criteria in the Chilean case. In relation to the aforementioned, the article focuses on problems such as the agricultural dimension of the country, the centralization of knowledge about nature and the construction and contrast of "national nature" during the Exhibition.

Climate change represents one of the biggest threats to agriculture today. The aim of this paper is to analyze the decision and intensity of adaptation to this phenomenon among farmers in Central Chile and to identify the factors that influence the adoption of adaptation measures. The list of adaptation practices was created with the assistance of a panel of experts. A two-part hurdle model was used to identify the adoption and intensity of adoption. The decision to adapt is strongly influenced by land tenure security and access to weather information, which increase the probability of adaptation by 13% and 30%, respectively. The intensity of adaptation is highly influenced by affiliation to a farm organization or association, which tends to boost intensity by 72.2%. Land tenure also increases intensity by 44.5%. Years of experience in agriculture and the income obtained from crops in the previous season also have a positive impact. Empirical results reveal that the most effective way to reduce barriers to adaptation is to improve access to information, while a highly relevant mode to increase the intensity of adaptation is to encourage social networking.

South America sustains an important part of the world's terrestrial biodiversity and its population is highly urbanized. Global syntheses have revealed a paucity of urban ecological research in the region; however, local research might be overlooked due to language barriers. As a contribution to disseminating local knowledge, we conducted a synthesis of Spanish-language literature on bird species richness in the Southern Cone of South America - an area of high diversity, endemism, and more than half of the world's terrestrial biome types. In this systematic review, we identified patterns and trends in the literature, and the variables that influence bird species richness. Research has focused on national capital cities and green areas (large urban parks). Most studies covered short periods of time (1 year or less) and involved one season only (reproductive). The most studied biomes were temperate grasslands, savannas and shrublands, and Mediterranean and temperate forests, and no studies were found in mountains or deserts. Bird species richness in cities from the Southern Cone was positively influenced by vegetation cover and plant and habitat diversity; whereas variables associated with urban cover and disturbance exhibited negative effects. Important gaps in knowledge include: research in small and medium size cities, in overlooked biomes (deserts, xeric shrublands, and montane grasslands and shrublands), long-term research comprising different seasons, the inclusion of green spaces other than urban parks, and interdisciplinary studies that consider environmental, social, and economic components of urban ecosystems. By filling these key knowledge gaps, researchers from South America can contribute to the development of science-based actions to preserve nature in an urbanizing world. [ABSTRACT FROM AUTHOR]

Global commitments prioritize protection of wildlife and improvements to human wellbeing. Local disconnects in these commitments are rarely acknowledged—or their implications assessed—preventing the development of effective solutions. National and international efforts to protect marine mammals along South America's west coast have contributed to species recovery, but also to conflict between sea lions and small‐scale fisheries. To understand the concerns ultimately motivating this conflict, we assessed how 301 coastal small‐scale fishers perceive their interactions with South American sea lions (Otaria flavescens). We then reviewed the terrestrial human–wildlife literature to identify potential management solutions to resolve the conflict. We find that fishers are chiefly concerned with increases in sea lion populations, perceive that sea lion interactions have significantly increased over the past 80 years, and report sea lion‐driven catch and income losses of ≥26%. We propose solutions to manage conflict that are sensitive to heterogeneity among fisher groups. [ABSTRACT FROM AUTHOR]

The centre–periphery hypothesis (CPH) postulates that populations close to the centre of a species distribution will exhibit higher genetic diversity and lower genetic differentiation than populations located at the edge of the distribution. The centre of a species' distribution might represent an optimum for the environmental factors influencing the species absolute fitness and, therefore, genetic diversity. In species with wide distribution, the geographical variation of biotic and abiotic variables is crucial to understand the underlying mechanisms of the CPH. We evaluated the CPH and specifically tested which environmental variables better explained the patterns of genetic diversity in the kissing bug Mepraia spinolai, one of the main wild vectors of Chagas disease in southern South America, distributed across three Mediterranean climatic ecoregions in Chile. We analysed 2380 neutral single nucleotide polymorphisms to estimate genetic diversity. Mean winter temperature, mean summer temperature, vegetation cover, population abundance, proportion of winged individuals and female abdomen area were measured for each kissing bug population to construct a model. Lower genetic diversity was detected in populations at the edge of the distribution compared to those in the centre. However, genetic differentiation was not higher in the periphery. Genetic diversity was related to climatic and biological variables; there was a positive relationship with mean winter temperature and a negative association with mean summer temperature and body size. These results partially support the CPH and identify biotic (abdomen area) and abiotic (winter/summer temperatures) factors that would affect genetic diversity in this restricted‐dispersal species of epidemiological relevance.

The changing composition of the atmosphere, driven by anthropogenic emissions, is the cause of anthropogenic climate change as well as deteriorating air quality. Emission inventories are essential to understand the contribution of various human activities, model and predict the changing atmospheric composition, and design cost-effective mitigation measures. At present, national emission inventories in South America (SA) focus on Greenhouse Gases (GHG) as part of their obligation to the United Nations Framework Convention for Climate Change (UNFCC) within the framework of their national communications. Emission inventories other than GHG in SA focus mainly on growing urban areas and megacities. Therefore, studies examining air quality at national, regional or continental scales in SA depend on (down-scaled) global emission inventories. This paper examines the emission estimates of air pollutants from various global inventories for five SA countries, namely Argentina, Brazil, Chile, Colombia and Peru. A more detailed analysis is conducted for the EDGAR and ECLIPSE emission inventories, in particular comparing local city-scale inventories of a major city in each country. Although total emissions between down-scaled global inventories and local city inventories are often comparable, large discrepancies exist between the sectoral contributions. This is critical, as the mitigation of poor air quality will depend on addressing the right sources. Potential sources of discrepancies between global and local inventories include the spatial distribution proxies, difference in emission factors used and/or the use of generic statistical country data when estimating emissions. This highlights the importance of using local information when generating national emission inventories, especially for air quality modeling and development of effective mitigation measures. This study represents the first step towards an increased understanding of the strengths and weaknesses of emissions information in SA. • Emissions from various inventories for 5 South American (SA) countries are examined. • Downscaled Global & city emissions present large discrepancies for the same domain. • Global emission inventory to derive city emission for AQ modeling is not suggested. • Increasing the understanding of strengths and weaknesses of emissions data for SA.

This study evaluates hindcast simulations performed with a regional climate model (RCM, RegCM4) driven by reanalysis data (ERA-Interim) over the Pacific coast and Andes Cordillera of extratropical South America. A nested domain configuration at 0. 44 ∘ (∼ 50 km) and 0. 09 ∘ (∼ 10 km) spatial resolutions is used for the simulations. RegCM4 is also driven by a global climate model (GCM, MPI-ESM-MR) on the same domain configuration to asses the added values for temperature and precipitation (historical simulations). Overall, both 10 km hindcast and historical simulation results are promising and exhibit a better representation of near-surface air temperature and precipitation variability compared to the 50 km simulations. High-resolution simulations suppress an overestimation of precipitation over the Andes Cordillera of northern Chile found with the 50 km simulations. The simulated daily temperature and precipitation extreme indices from 10 km hindcast simulation show a closer estimation of the observed fields. A persistent warm bias ( ∼ + 4 ∘ C ) over the Atacama Desert in 10 km hindcast simulation reveals the complexity in representing land surface and radiative processes over the desert. Difficulties in capturing the temperature trend in northern Chile are notable for both hindcast simulations. Both resolutions exhibit added values for temperature and precipitation over large parts of Chile, in particular, the 10 km resolves the coastal-valley Andes transitions over central Chile. Our results highlight that resolutions coarser than 50 km (e.g., GCMs and reanalysis) miss important climate gradients imposed by complex topography. Given that the highest spatial resolution of the current regional simulations over the South America is about 50 km, higher resolutions are important to improve our understanding of the dynamical processes that determine climate over complex terrain and extreme environments.

Denture marking (DM) helps identify edentulous people with different methods. Analyzing perceptions and attitudes of denture wearers would enable understanding of the practical aspects, an analysis still absent in South America. Fifty‐three individual candidates for removable dentures were instructed on disaster victim identification (DVI) and the usefulness of DM for this purpose. They were physically shown eight DM systems and a questionnaire to which they responded by highlighting preferences in those systems. Although 98.11% did not know that dentures could be marked, only 9.43% denied interest in some type of DM. The 90.57% would mark their dentures with some system, preferring the inclusion of QR codes or a micro SIM card. The proven weaknesses of DVI and propensity for disaster mean this community in Chile is an opportunity to implement DM systems. Obstacles may come not from patients but from their dentists, educational institutions, or a lack of public policies. [ABSTRACT FROM AUTHOR]

Ecosystems where carbon fluxes are being monitored on a global scale are strongly biased toward temperate Northern Hemisphere latitudes. However, forest and moorland ecosystems in the Southern Hemisphere may contribute significantly to the global and regional C balance and are affected by different climate systems. Here, we present the first data from an old-growth forest representative of temperate, broad-leaved rainforests from southern South America. Carbon fluxes monitored over two years using the eddy covariance technique showed that this rainforest acts as an annual sink (-238 ± 31 g C/m²). However, there were significant pulses of carbon emission associated with dry episodes during the summer months (i.e., peak of the growing season) and periods of significant carbon fixation during the cold austral winter, indicating that the carbon balance in this forest is very sensitive to climate fluctuations. The carbon fixation surges in winter seem to be related to the mild temperatures recorded during this period of the year under the prevailing oceanic climate. Winter carbon gain was more relevant in determining the annual carbon balance than summer pulse emissions. Regarding the annual carbon balance, this southern forest resembles the patterns observed in montane tropical forests more than the behavior of narrow-leaved evergreen temperate forests from the Northern Hemisphere. These patterns make this southern forest type relevant to understanding the mechanisms and thresholds that control ecosystem shifts from carbon sinks and sources and will provide key data to improve global dynamic vegetation models.

South American temperate rainforests, a global biodiversity hotspot, have been reduced to nearly 30% of their original extent and most remaining stands are being degraded. Cavity-nesting vertebrate communities are dependent on cavity-bearing trees and hierarchically structured within nest webs. Evaluating the actual degree of cavity dependence (obligate, non-obligate) and the preferred attributes of trees by cavity nesters is critical to design conservation strategies in areas undergoing habitat loss. During three breeding seasons (2010-2013), we studied the cavity-nesting bird community in temperate rainforests of Chile. We found the highest reported proportion of tree cavity nesters (n = 29 species; 57%) compared to non-cavity-using birds for any forest system. Four species were excavators and 25 were secondary cavity nesters (SCNs). Among SCNs, ten species were obligate and 15 were non-obligate cavity nesters. Seventy-five percent of nests of SCNs were located in cavities produced by tree decay processes and the remaining 25% were in cavities excavated mainly by Pygarrhichas albogularis and Campephilus magellanicus. Nest web structure had a low dominance and evenness, with most network interactions occurring between SCNs and large decaying trees. Tree diameter at breast height (DBH) was larger in nest-trees (57.3 cm) than in available trees (26.1 cm). Cavity nesters showed a strong preference for dead trees, both standing and fallen (58% of nests). Our results stress that retaining large decaying and standing dead trees (DBH > 57 cm), and large fallen trees, should be a priority for retention in forest management plans in this globally threatened ecosystem.

In theory, building resilience is touted as one way to deal with climate change impacts; however, in practice, there is a need to examine how contexts influence the capacity of building resilience. A participatory process was carried out through workshops in regions affected by drought in Chile in 2014. The aim was to explore how resilience theory can be better applied and articulated into practice vis-á-vis participatory approaches that enrich the research process through the incorporation of co-produced. The results show that there are more differences in responses by type of actor than between regions, where issues of national interest, such as 'education-information' and 'preparedness', are highlighted over others. However, historically relevant local topics emerged as differentiators: decentralisation, and political will. This reinforces why special attention must be given to the different understandings in knowledge co-production processes. This study provides evidence and lessons on the importance of incorporating processes of the co-production of knowledge as a means to better articulate and transfer abstract concepts, such as resilience theory, into practice.

Abstract: Dispersal and adaptation are the two primary mechanisms that set the range distributions for a population or species. As such, understanding how these mechanisms interact in marine organisms in particular – with capacity for long‐range dispersal and a poor understanding of what selective environments species are responding to – can provide useful insights for the exploration of biogeographic patterns. Previously, the barnacle Notochthamalus scabrosus has revealed two evolutionarily distinct lineages with a joint distribution that suggests an association with one of the two major biogeographic boundaries (~30°S) along the coast of Chile. However, spatial and genomic sampling of this system has been limited until now. We hypothesized that given the strong oceanographic and environmental shifts associated with the other major biogeographic boundary (~42°S) for Chilean coastal invertebrates, the southern mitochondrial lineage would dominate or go to fixation in locations further to the south. We also evaluated nuclear polymorphism data from 130 single nucleotide polymorphisms to evaluate the concordance of the signal from the nuclear genome with that of the mitochondrial sample. Through the application of standard population genetic approaches along with a Lagrangian ocean connectivity model, we describe the codistribution of these lineages through a simultaneous evaluation of coastal lineage frequencies, an approximation of larval behavior, and current‐driven dispersal. Our results show that this pattern could not persist without the two lineages having distinct environmental optima. We suggest that a more thorough integration of larval dynamics, explicit dispersal models, and near‐shore environmental analysis can explain much of the coastal biogeography of Chile.

Ecological disturbances triggered by earthquakes and volcanic eruptions are of fundamental importance in structuring the temperate forests of southwestern South America and New Zealand. We review studies of the ecological effects of these tectonic phenomena and how they have been central to progress in the modern development of forest ecology in both regions. Studies of tectonic influences on the dynamics of southern temperate rainforests of Chile and New Zealand published in the 1970s and early 1980s contributed prominently to the shift away from the equilibrium paradigms dominant globally in the 1960s and towards modern non-equilibrium frameworks of forest dynamics. Empirical studies of tectonic ecology in these temperate forests in combination with critical evaluations of earlier successional theory have significantly advanced understanding of the roles of coarse-scale disturbance in the dynamics of forests in southwestern South America and New Zealand. Recognition that cohort forest structures triggered by exogenous disturbances such as wind storms and tectonic events are the norm rather than all-aged structures has been of fundamental importance to understanding the dynamics of these forests. The non-equilibrium patch dynamics framework for interpreting forest structure and dynamics bolstered by tectonic ecology studies in southern South America and New Zealand was of key importance in refining older views of these forests as being out of equilibrium with contemporary climate, revising understanding of the effects of introduced browsing animals on forest structure, and guiding the development of appropriate forest management practices.
