Few topics in wildlife conservation are as controversial, emotive, or command as much public and political attention, as trophy hunting. International discourses regarding trophy hunting are characterised by radically contradictory assertions, ranging from claims that trophy hunting is a humane and socially acceptable wildlife management tool which benefits more animals than it kills, to claims that it is cruel, socially unacceptable, and drives species to extinction. So, which is it? We argue that using a single, blanket term “trophy hunting” obscures substantial and important variation in how and why people pay to hunt and keep trophies. Consequently, polarised disagreements over whether “trophy hunting” is good or bad, acceptable or unacceptable, beneficial or harmful, conflate arguments about fundamentally different activities. We urge conservation scientists and practitioners, politicians, journalists, and advocates on all sides to communicate more clearly and carefully about which specific hunting activities they believe are right or wrong, beneficial, or harmful, acceptable or unacceptable, to whom, and for what reasons.

Social influence impacts individuals’ behavior through norms – the perceived appropriateness of behaviors – and social referents, whose behavior is copied by others. Interventions using social influence may help promote conservation-friendly behaviors. We explored how perceptions are influenced by descriptive norms (what people do) and social referents (who does it) in relation to livestock management in Kenya. By presenting participants with vignettes describing different livestock management scenarios, we explored how two norms (‘high’ vs. ‘low’ standards of livestock management) and three social referents (‘neighbor,’ ‘leader,’ ‘father’) influence participants’ perceptions of aspects of livestock management. More senior social referents and ‘high’ standard norms were associated with greater impact on perceived importance of livestock management behaviors. Age also had an effect, with higher perceived importance and greater effect of norm treatment in younger respondents. Encouraging social seniors to model desired behavior may be a possible strategy for conservation behavioral interventions.

Natural history documentaries are a globally important source of information about wildlife, conservation and environmental issues, and they are the closest many will get to seeing featured animals and their behaviour in the wild. They are entertainment, certainly, but may also inform people's knowledge of the natural world and influence their ideas on conservation of species and habitats. We locate our perspective in the existing literature analysing wildlife documentary making and its effects. We argue that a conspicuous pre‐occupation with the ‘personalisation’ of individual animals and the injection of false jeopardy in recent wildlife documentaries leads to significant misinformation and creates problems for public understanding of wider conservation. We illustrate our point by detailing episodes from the BBC natural history series Dynasties, discussing personalisation, anthropomorphism and the use of jeopardy to gain emotive impact and audience engagement. We find that narratives are framed around a single individual, that ‘stories’ are framed as soap operas, that jeopardy is emphasised throughout and that animals are endowed with the capacity to be aware of, and work towards, the dynasties of the title. With conservation increasingly relying on public support, we argue that it is important that people are presented with factually correct information, and portraying wild animals as soap opera style characters is neither honest nor helpful.

Using an experimental approach, we analyzed the self-reported changes in farmers’ attitudes toward the African lion (Panthera leo) and a community-based lion conservation program (i.e., the Long Shields Community Guardians), before and after implementation. This program protects livestock and mitigates lion depredation through non-lethal means, with the aim of promoting human-lion coexistence. Results indicated a significant positive shift in attitudes of lions by farmers in the treatment group. This was also the case for farmers in what was recognized as a second unplanned treatment group, called the intermediate group, who learned about the program through communication within their peer network. This article contributed to the growing literature on conservation evaluation and demonstrates that people’s attitudes are valuable for assessing the impact of conservation programs.

Woody plant encroachment (WPE) is reshaping the physiognomy of grasslands and savannahs worldwide. At the same time, this habitat conversion is accelerating the loss of associated biodiversity. In general, studies on WPE have focused on abiotic factors, singly or in combination, that trigger this phenomenon. Despite its ecological relevance, very few studies have tackled the effects of WPE-spurred habitat transformation on animal species dependent on relatively open areas such as grasslands and savannas for survival. We studied a relict and almost extinct population of large, herbivorous guanacos ( Lama guanicoe ) in the Gran Chaco region, Santa Cruz department, Bolivia. We tested whether guanacos were using habitats (at particular and distinct stages of WPE) in relation to their availability. Although this species is considered a generalist herbivore. We tested variation in habitat use focusing on two spatial scales. First, at the landscape level, we performed aerial surveys. Second, at the fine scale, we tracked six groups of guanacos for twenty months and documented the various habitats used within their approximate home ranges. At both scales, we performed a Manly-Chesson’s index referring to the standardised proportional use of each habitat divided by the proportional availability of each, with the values for all habitats summing to 1. An index value 1 suggests, respectively, that a habitat is avoided or selected. We found a disproportionate use of open vegetation (scrubland and grassland) by guanacos in relation to habitat availability at both scales. In addition, the current distribution range of the species is restricted to less than 800 km 2 of the approximately 3,000 km² potentially available in 1998. We confirmed a contraction between 1996 and 2006 in the distribution of the local Chacoan guanaco population from the area where guanacos were first monitored towards the Kaa-Iya National Park border. Our results showed that guanacos are restricted to relatively open areas. Furthermore, the observed reduction in the area previously occupied by the species could be the beginning of a distributional shift and potential loss of the guanaco’s geographic range due to habitat replacement. The latter was also reflected in a previous dietary study of this population we found that guanacos largely consumed the native grass A. mendocina (Poaceae), which has shrunk in distribution by 90 % in this region over a 40 year period and is gradually being replaced by an invasive forb, Lippia sp. Therefore, if the overall purpose on evaluating habitat use is to understand the basic requirements to sustain this population of guanacos, we need to highlight the poor quality and acute regression of the current preferred habitat. In this case, habitat structure can have a profound effect on the success of the guanaco population recovery and its long-term establishment. Therefore, we urge researchers and decision makers to look beyond the more direct human-induced pressures on the species, such as hunting, competition with domestic livestock and agricultural development and consider the importance of WPE as a direct driver for habitat loss.

1. People hunt and kill animals for sport in many parts of the world. This raises many issues, some of which were brought to the fore when a lion Panthera leo, nicknamed Cecil, was killed by a trophy hunter in Zimbabwe in 2015. Cecil's death led to an unprecedented public reaction in Europe and the USA, and a debate in which opponents and supporters of sport hunting advanced different types of argument based on, inter alia, conservation, animal welfare and economics. 2. The reaction to the Cecil event provides a perspective for scrutinizing sport hunting more widely. In this article we explore parallels between lion trophy hunting in Africa (which can involve either wild or captive‐bred lions) and shooting of common pheasant Phasianus colchicus, a sport which is largely sustained in the UK by the annual release of over 40 million captive‐bred birds. 3. These two forms of sport hunting share common themes that are likely to be influential for the future of sport hunting more widely. These include the extent to which sport hunting maintains land for wildlife, and the impacts of intensification (e.g. the extent to which quarry are reared and released). Concern for the welfare of quarry animals is a dominant theme in debates about hunting. 4. These themes are likely to be relevant for the conservation of many species hunted for sport. Increasing distaste for the killing of animals for sport in many countries may lead to the end of some types of sport hunting, with implications for both habitat and wildlife conservation. It would be both prudent and appropriate for conservationists to increase the urgency with which they seek alternative methods for preventing loss of biodiverse land to other uses.

Militarisation of conservation (sometimes known as 'green militarisation') is an issue of growing international interest. Rhino horn is immensely valuable (in 2013 its value exceeded that of gold or cocaine), and its illegal trade has attracted widespread attention. Conservationists have declared a 'war' on poaching, with extensive military resources deployed to combat it. This sometimes includes operations which are referred to, particularly in the media, as 'shoot-to-kill'. These can be tantamount to extra-judicial killings. We scrutinise this issue using 'Just War' principles, to explore whether the 'war' on poaching meets the criteria expected of armed conflict. Our perspective suggests that it fails both ethical and pragmatic examination. This piece encourages conservation scientists, and the public, to consider which actions are justified in protecting wildlife, and how we should rethink conservation policy to achieve ethical, successful outcomes for both people and wildlife.

Quantifying the distribution and size of home ranges is critical for understanding animal spatial dynamics. This is particularly important for large carnivores in fragmented landscapes. Most studies that estimate home range consider only a bivariate frequency distribution represented by a two‐dimensional planimetric surface. The underlying assumption of these approaches is that the animals inhabit landscapes that are completely flat. Of course, this is rarely the case. Here we investigated the influence of vertical relief and three‐dimensional landscape features on the home range patterns of a high density carnivore. Via GPS telemetry‐tracking of a population of Persian leopards Panthera pardus saxicolor (n = 6), and globally‐available digital elevation models (DEMs), we calculated the surface area of home ranges in comparison to traditional planimetric estimates. We also investigated predation patterns of leopards across elevation gradients using GPS location data and kill site analysis. The topographic measurements exceeded planimetric estimates by up to 38% which suggests that planimetric modeling underestimates home range size, particularly when animals inhabit variable terrain. We also observed that resident leopards exhibit significant altitudinal partitioning of predation, suggesting that leopards that have overlapping home ranges may still utilize exclusive hunting territories. We discuss the ways in which planimetric approaches may be underestimating aspects of animal ranging behavior and ecology. We conclude that topography should be considered, not as an ancillary metric, but as an important aspect of home range calculation. Our approach can enhance understanding of spatial requirements, population density, intra‐guild sympatric competition and conflict management of large felids inhabiting rugged landscapes.

Bushmeat consumption in Madagascar is increasingly acknowledged as one of the major threats to its wild vertebrates. Nevertheless, few studies have examined the drivers of the consumption of protected versus legally huntable wild species, or examined its variance across Madagascar’s protected and unprotected areas. This research provides a novel study of the consumption of protected, unprotected, and fish/eel species between forest types (deciduous and rainforest), as well as across a gradient of protected habitat (National Park, Reserve, Unprotected). Members of 1750 households were interviewed across four regions, including two national parks, two reserves, and two unprotected forests. Household demographic, socioeconomic, cultural, and geographic variables were explored as possible predictors of bushmeat consumption. We found that poorer households reported consuming greater quantities of protected species whereas wealthier households reported consuming greater quantities of fish and eel. Households located inside Andasibe-Mantadia National Park, Madagascar’s most visited protected area, reported consuming the greatest quantities of protected species. Interviewees’ most favoured meat was from livestock, and fish. The consumption pattern of wild species reflected interviewees’ stated preference for species that are either unlisted (e.g. tilapia fish) under Malagasy species protection laws, classified as pest (e.g. bushpig) and/or game species (e.g. tenrec). Most protected species (such as lemurs and carnivorans) were interviewees’ least favoured wild meats. Given the lack of cultural affinity, and low preference for the consumption of most protected species, our results suggest that improving accessibility to domestic meat is a promising strategy for reducing the consumption of protected species.

Variation in moonlight affects foraging, hunting and vigilance behaviours in many nocturnal species. Here, we explore the effect of moonlight on the movement and hunting behaviour of African lions. Previous studies found bright moonlight is associated with reduced hunting success; however, those studies were largely undertaken in open habitats where predators are easily seen by prey species on moonlit nights. In this study we explored whether moonlight affected hunting behaviour and success in a largely wooded environment. Measures of short-term lion movements (distance moved, displacement, and path tortuosity) derived from GPS telemetry data were used as indicators of movement behaviour. Field observations of belly distension were used to assess recent food intake. Lions had greater belly distension (indicating feeding success) on dark nights. However, this change in feeding success was not reflected by lion movement patterns – there was no evidence that these changed across moon phases. There was no evidence that lions used more covered habitats on brighter nights to facilitate concealment.

Conservation planning needs reliable information on spatial patterns of biodiversity. However, existing data sets are skewed: some habitats, taxa, and locations are under-represented. Here, we map geographic publication density at the sub-national scale of individual 'provinces'. We query the Web of Science catalogues SCI and SSCI for biodiversity-related publications including country and province names (for the period 1993-2016). We combine these data with other provincial-scale factors hypothesised to affect research (i.e. economic development, human presence, infrastructure and remoteness). We show that sites that appear to be understudied, compared with the biodiversity expected from their bioclimatic conditions, are likely to have been inaccessible to researchers for a diversity of reasons amongst which current or recent armed conflicts are notable. Finally, we create a priority list of provinces where geographic publication bias is of most concern, and discuss how our provincial-scale model can assist in adjusting for publication biases in conservation planning., Comment: 10 pages; 3 figures; 1 table;R code on https://github.com/raffael-hickisch; data at https://zenodo.org/record/998889; interactive at http://bit.ly/publication_density_map

The North American genus Silphium is receiving global attention for its potential in the development of new food, forage, and industrial crops, including cellulosic biomass for biofuel. Little is known about the effect of plant population density on biomass production in large, coarse perennial forbs. Our objective was to evaluate the effect of variation in plant density on biomass production and stand morphology of cup plant (Silphium perfoliatum L.). Plant population densities of 17,000, 34,000, and 68,000 plants ha-1 were evaluated for biomass production in a single-harvest per annum system for three years at Brookings, SD and Arlington, WI. Biomass increased linearly by 43% between the low and high density at Brookings; whereas, at Arlington, response to variation in plant density was year dependent. Shoots plant-1 was inversely related to plant density with linear regression explaining >95% of the variation. Our results strongly suggested that further studies of effects of plant population density on biomass production in cup plant should include evaluation of, in addition to, densities higher than 68,000 plants ha-1.

To date, most candidate systems for producing herbaceous cellulosic biomass have been composed of monocultures of perennial or annual grasses. Ecosystem goods and services provided from these biomass feedstock production systems could be increased dramatically with mixing of one or more forb species that would increase biodiversity and provide habitat for pollinators. Cup plant (Silphium perfoliatum L.) is featured with many desirable characteristics, such as high biomass potential, adaptation to marginal soils, and attractiveness to pollinators, desirable in a dicot species to grow in mixtures with perennial warm-season grasses. The objective of this study was to compare cup plant, switchgrass (Panicum virgatum L.), and prairie cordgrass (Spartina pectinata Link) monocultures to their mixtures for biomass production on prime and poorly drained marginal crop land for two years in both South Dakota and Wisconsin. In Wisconsin, monocultures of prairie cordgrass and cup plant and their mixture produced more biomass (8.1 Mg·ha-1) than the switchgrass monoculture and switchgrass/cup plant mixture (5.3 Mg·ha-1) on both prime and marginal land. While in South Dakota, drought and meristem destruction by the cup plant moth (Eucosma giganteana Riley) caused large reductions in biomass production (1.7 Mg·ha-1) in both years, with the switchgrass/cup plant mixture on marginal land having the highest yield (2.1 Mg·ha-1). Our study showed binary mixtures of cup plant and native warm-season grasses have great potential for increasing biodiversity and other ecosystem goods and services, relative to monocultures, for sustainable biomass feedstock production on poorly drained marginal land in the northcentral USA.

Conservation scientists are increasingly recognizing the need to evaluate the effectiveness of interventions to improve human–wildlife coexistence across different contexts. Here we assessed the long-term efficacy of the Long Shields Community Guardians programme in Zimbabwe. This community-based programme seeks to protect livestock and prevent depredation by lions Panthera leo through non-lethal means, with the ultimate aim of promoting human–lion coexistence. Using a quasi-experimental approach, we measured temporal trends in livestock depredation by lions and the prevalence of retaliatory killing of lions by farmers and wildlife managers. Farmers that were part of the Long Shields programme experienced a significant reduction in livestock loss to lions, and the annual number of lions subject to retaliatory killing by farmers dropped by 41% since the start of the programme in 2013, compared to 2008–2012, before the programme was initiated. Our findings demonstrate the Long Shields programme can be a potential model for limiting livestock depredation by lions. More broadly, our study demonstrates the effectiveness of community-based interventions to engage community members, improve livestock protection and ameliorate levels of retaliatory killing, thereby reducing human–lion conflict.

Understanding coexistence between humans and threatened wildlife is a central focus in conservation. Way Kambas National Park in Sumatra Island, Indonesia, harbors one of the largest populations of the critically endangered Sumatran elephant (Elephas maximus sumatranus). The people who live alongside this population are affected by intensive crop foraging. Our study investigated the factors which influenced attitudes toward elephants. We then evaluated the implications of reported attitudes for future willingness to live with elephants. We surveyed 660 respondents in 22 villages around the park. People generally reported positive attitudes toward elephants (smartness 95%, usefulness 62%, importance 57%, and pleasantness 53%), apart from where human safety was concerned (safety 11%). Each dimension of attitude was explained by different factors including age, gender, knowledge of elephants, and distance to crop foraging locations. Most respondents (62%) expressed no willingness to coexist with elephants. Such willingness was lower when elephants were perceived to be more dangerous, but higher if beliefs in the benefits of elephants were greater. Efforts to improve crop foraging mitigation practice and to increase people's awareness of elephant benefits may promote support for their conservation. Through this study, we advocate the integration of social science to promote human–wildlife coexistence strategies, an approach that is currently limited in Indonesia. Published version This study was funded by US Fish and Wildlife Service.

SummaryPassive acoustic monitoring is rapidly gaining recognition as a practical, affordable and robust tool for measuring gun hunting levels within protected areas, and consequently for its potential to evaluate anti-poaching patrols’ effectiveness based on outcome (i.e., change in hunting pressure) rather than effort (e.g., kilometres patrolled) or output (e.g., arrests). However, there has been no report to date of a protected area successfully using an acoustic grid to explore baseline levels of gun hunting activity, adapting its patrols in response to the evidence extracted from the acoustic data and then evaluating the effectiveness of the new patrol strategy. We report here such a case in Cameroon’s Korup National Park, where anti-poaching patrol effort was markedly increased in the 2015–2016 Christmas/New Year holiday season to curb the annual peak in gunshots recorded by a 12-sensor acoustic grid in the same period during the previous 2 years. Despite a three- to five-fold increase in patrol days, distance and area covered, the desired outcome – lower gun hunting activity – was not achieved under the new patrol scheme. The findings emphasize the need for adaptive wildlife law enforcement and how passive acoustic monitoring can help attain this goal, and they warn about the risks of using effort-based metrics of anti-poaching strategies as a surrogate for desired outcomes. We propose ways of increasing protected areas’ capacity to adopt acoustic grids as a law enforcement monitoring tool.

Background Tackling behavioural questions often requires identifying points in space and time where animals make decisions and linking these to environmental variables. State-space modeling is useful for analysing movement trajectories, particularly with hidden Markov models (HMM). Yet importantly, the ontogeny of underlying (unobservable) behavioural states revealed by the HMMs has rarely been verified in the field. Methods Using hidden Markov models of individual movement from animal location, biotelemetry, and environmental data, we explored multistate behaviour and the effect of associated intrinsic and extrinsic drivers across life stages. We also decomposed the activity budgets of different movement states at two general and caching phases. The latter - defined as the period following a kill which likely involves the caching of uneaten prey - was subsequently confirmed by field inspections. We applied this method to GPS relocation data of a caching predator, Persian leopard Panthera pardus saxicolor in northeastern Iran. Results Multistate modeling provided strong evidence for an effect of life stage on the behavioural states and their associated time budget. Although environmental covariates (ambient temperature and diel period) and ecological outcomes (predation) affected behavioural states in non-resident leopards, the response in resident leopards was not clear, except that temporal patterns were consistent with a crepuscular and nocturnal movement pattern. Resident leopards adopt an energetically more costly mobile behaviour for most of their time while non-residents shift their behavioural states from high energetic expenditure states to energetically less costly encamped behaviour for most of their time, which is likely to be a risk avoidance strategy against conspecifics or humans. Conclusions This study demonstrates that plasticity in predator behaviour depending on life stage may tackle a trade-off between successful predation and avoiding the risks associated with conspecifics, human presence and maintaining home range. Range residency in territorial predators is energetically demanding and can outweigh the predator’s response to intrinsic and extrinsic variables such as thermoregulation or foraging needs. Our approach provides an insight into spatial behavior and decision making of leopards, and other large felids in rugged landscapes through the application of the HMMs in movement ecology.

Human&ndash, wildlife conflict occurs globally. Attempts to control &lsquo, pest&rsquo, wildlife involve killing and harming the welfare of animals on a vast scale. We examined public perceptions of 10 wildlife species/groups and wildlife management, in and around UK homes, and public authority &lsquo, pest control&rsquo, provision, in an effort to identify ethical, welfare-friendly ways to reduce conflict. Most people reported never having problems with each of the 10 species, and reported problems for some species were largely tolerated. Wasps, mice, and rats were the most frequently problematic species, the least tolerated, and those for which local authorities most often offered pest control services. Do-It-Yourself pest control was preferred over professional control, except for with wasps. People wanted control to be quick, lasting, and safe for people and non-target animals. Where people accepted lethal control, they were nevertheless concerned for animal welfare. Drivers of pest status were complex, while drivers of demand for control were fewer and species-specific. Local authority pest control provision increased over the four years studied, but only half of councils offered advice on preventing/deterring wildlife, this advice was patchy and variable in quality. Greater focus is required on preventing/deterring rather than controlling wildlife problems. Councils should provide standardised, comprehensive advice on prevention/deterrence and prevention/deterrence services.

The Himalayan wolf Canis sp. and snow leopard Panthera uncia are found in the Nepalese Himalayas where conservation efforts target the latter but not the former. We conducted semistructured questionnaire surveys of 71 residents in upper Humla, upper Dolpa, and Kanchenjunga Conservation Area (KCA) during 2014–2016 to understand people's knowledge, perceptions, attitudes and interactions with these two carnivores. We fitted a cumulative link mixed model to predict Likert scale ordinal responses from a series of Generalized Linear Mixed Models. Overall, attitudes were more positive toward snow leopards than wolves. Livestock depredation was the main predictor of the general negative attitude toward wolves (Estimate = −1.30873; p = .029866) but there was no evidence for an effect for snow leopards (Estimate = −0.3640; p = .631446). Agropastoralists had more negative attitudes than respondents with other occupations toward both carnivores and men had more positive attitudes than women. Among our study areas, respondents in the community‐owned KCA had the most positive attitudes. Our findings illustrate the need to reduce human–carnivore conflict through a combined approach of education, mitigation, and economic cost‐sharing with respectful engagement of local communities. Specifically, to encourage more villagers to participate in livestock insurance schemes, they should be improved by including all large carnivores and adjusting compensation to the market value of a young replacement of the depredated livestock type. Carnivore conservation interventions should target the whole predator guild to achieve long‐term success and to protect the Himalayan ecosystem at large.

The persistence of endangered species may depend on the fate of a very small number of individual animals. In situ conservation alone may sometimes be insufficient. In these instances, the International Union for Conservation of Nature provides guidelines for ex situ conservation and the Convention on Biological Diversity (CBD) indicates how ex situ management can support the CBD's objectives by providing insurance policies for species. The circumstances that justify its use are uncertain. To evaluate the current in situ extinction risk and ex situ management of 43 critically endangered species of mammalian megafauna, we used nonmetric multidimensional scaling and geopolitical variables related to governance, economics, and national policy within their extant ranges. We then fitted generalized additive models to assess the contribution of each variable to the ordination. Fifteen (almost one-third) of the world's terrestrial mammalian megafauna are not the subject of any ex situ management. Seventy-three percent of these taxa occur in areas characterized by political uncertainty, such as border zones or areas affected by armed conflicts, mainly in Africa and the Middle East. A further 23% of taxa in ex situ programs do not meet sustainability criteria for inbreeding avoidance. Strategic conservation planning, such as the One Plan approach, may improve ex situ management for these taxa. Given the escalating trend in threats afflicting megafauna, ex situ management should be considered more rigorously, particularly in politically unstable regions, to achieve CBD Target 12 (prevent extinction of threatened species).Manejo Ex Situ como Protección contra la Extinción de la Megafauna de Mamíferos en un Mundo Incierto Resumen La persistencia de las especies en peligro puede depender del destino de un número muy pequeño de animales individuales. La conservación in situ por sí sola a veces puede ser insuficiente. Bajo estas instancias, la Unión Internacional para la Conservación de la Naturaleza proporciona directrices para la conservación ex situ y la Convención sobre la Diversidad Biológica (CBD) indica cómo el manejo ex situ puede apoyar a lograr sus objetivos al proporcionar políticas de protección para las especies. Las circunstancias que justifican el uso del manejo ex situ son inciertas. Para evaluar el actual riesgo de extinción in situ y el manejo ex situ de 43 especies de megafauna de mamíferos en peligro crítico de extinción usamos un escalamiento multidimensional no métrico, así como variables geopolíticas relacionadas con el gobierno, la economía y las políticas nacionales dentro de la distribución actual de estas especies. Después ajustamos los modelos sumativos generalizados para evaluar la contribución de cada variable a la ordinación. Quince (casi un tercio) de los mamíferos terrestres pertenecientes a la megafauna no están sujetos a ningún tipo de manejo ex situ. El 73% de estos taxones ocurren en áreas conocidas por su incertidumbre política, como zonas fronterizas o áreas afectadas por conflictos armados, principalmente en África y en el Oriente Medio. Además, un 23% de los taxones que sí se encuentran en programas de conservación ex situ no cumplen con los criterios de sustentabilidad para evitar la endogamia. La planeación de la conservación estratégica, como la estrategia de One Plan, podría mejorar el manejo ex situ para estos taxones. Dada la tendencia creciente en las amenazas que afectan a la megafauna, el manejo ex situ debería considerarse de manera más rigurosa, particularmente en las regiones con inestabilidad política, para alcanzar el Objetivo 12 de la CBD (evitar la extinción de especies amenazadas).濒危物种的续存可能取决于该物种极少数个体的命运;因此, 仅仅只有就地保护有时还不足够。在这些情况下, 世界自然保护联盟 (IUCN) 为迁地保护提供了指导方针, 《生物多样性公约 (CBD) 》也指出了迁地管理如何通过为物种提供保险政策来支持 CBD 目标。然而, 应在怎样的情况下合理利用迁地保护仍存在疑问。为了评估43种极度濒危的巨型哺乳动物目前的就地灭绝风险和迁地管理, 我们利用非度量多维标度法和动物现生分布区内与治理、经济和国家政策相关的地理政治变量进行了分析。我们还进一步拟合了广义加性模型以评估各变量对等级排序的贡献。世界陆生巨型哺乳动物中有15种 (近三分之一) 未被纳入任何迁地管理项目之中。这些类群中 73%分布在政治不稳定的地区, 如边境地区或受武装冲突影响的地区, 主要在非洲和中东。迁地保护项目中还有 23%的类群没有满足避免近亲繁殖的可持续性标准。战略保护规划, 如一体计划方案 (One Plan approach), 可以帮助改进这些物种的迁地管理。鉴于巨型动物面临的威胁仍在不断加剧, 为了实现 CBD 目标 12 (防止濒危物种灭绝), 应该更严格地考虑迁地管理, 特别是在政治不稳定的地区。 【翻译:胡怡思;审校:聂永刚】.

Simple Summary Acting to preserve biodiversity can involve harming individual animals. It has recently been argued that conventional practice has placed too much emphasis on the preservation of collective entities, such as populations and species, at the expense of suffering for individuals. At least some advocates of the ‘Compassionate Conservation’ movement find any deployment of lethal measures in the interests of conservation to be unacceptable. This shifts the balance of priorities too far. While conservationists have a duty to minimise harm, and to use non-lethal measures where feasible, there will be serious implications for conservation if this movement were to be widely influential. Furthermore, the ‘do-no-harm’ maxim the compassionate conservationists advocate does not always promote the welfare of individual animals. Abstract Human activity affecting the welfare of wild vertebrates, widely accepted to be sentient, and therefore deserving of moral concern, is widespread. A variety of motives lead to the killing of individual wild animals. These include to provide food, to protect stock and other human interests, and also for sport. The acceptability of such killing is widely believed to vary with the motive and method. Individual vertebrates are also killed by conservationists. Whether securing conservation goals is an adequate reason for such killing has recently been challenged. Conventional conservation practice has tended to prioritise ecological collectives, such as populations and species, when their interests conflict with those of individuals. Supporters of the ‘Compassionate Conservation’ movement argue both that conservationists have neglected animal welfare when such conflicts arise and that no killing for conservation is justified. We counter that conservationists increasingly seek to adhere to high standards of welfare, and that the extreme position advocated by some supporters of ‘Compassionate Conservation’, rooted in virtue ethics, would, if widely accepted, lead to considerable negative effects for conservation. Conservation practice cannot afford to neglect consequences. Moreover, the do-no-harm maxim does not always lead to better outcomes for animal welfare.

Clouded leopards are one of the least known of larger felids and were believed to be extinct in Nepal until 1987. They are particularly interesting because their Asian range spans a diversity of habitats in the fastest disappearing forests in the world and encompasses a guild which differs in composition from place to place. As a part of a wider camera-trapping study of this guild, involving 2948 camera traps at 45 sites in nine countries, and paralleling a similar study of the Sunda clouded leopard including a further 1544 camera traps spanning 22 sites distributed across two countries, we deployed 84 pairs of camera traps for 107 days in 2014 and 2015 at Langtang National Park, Nepal between 1823 and 3824 m a.s.l. within a grid encompassing c. 120 km2. We documented the presence of clouded leopards for the first time at an altitude as high as 3498 m a.s.l. Naïve occupancy for clouded leopard was 8.6% (correcting for detection, 10.1%). Clouded leopards were least active in the middle of the day, and largely crepuscular and nocturnal, as were the common leopards and leopard cats. The peak of clouded leopard activity overlapped with that of musk deer. Prey species for both clouded leopard and common leopard were available across the elevation range studied although the availability of some prey species declined as elevation increased, whereas Himalayan serow, Himalayan goral, and musk deer showed no association with elevation. Before this study, there was no hard evidence that clouded leopards occurred above 2300 m a.s.l., having documented them at almost 4000 m a.s.l. in the Himalayas, we emphasise the importance of this extreme portion of the species’ range where climate is likely to change more rapidly and with greater consequences, than the global average. The discovery of clouded leopards in Langtang National Park considerably extends their known range, and raises the possibility that they occur from the Terai in southern Nepal up to the Nepal-Tibet (China) border in the north. Insofar as this study has extended the known extreme boundary of the clouded leopard’s geographic range to encompass Langtang National Park in the Nepali Himalayas.

Describing predation patterns and especially estimating kill and consumption rates is essential for understanding the functional responses of predators. An understanding of the carrying capacity of the landscape, based on prey availability, also helps to formulate recovery plans for persecuted species. We studied the feeding behavior of the Persian leopard (Panthera pardus saxicolor) in Tandoureh National Park (355 km2) in northeastern Iran, near the Turkmenistan border. Between September 2014 and May 2017, we collared and monitored 6 adult leopards (5 males and 1 female) using GPS-satellite Iridium collars. We investigated 310 clusters of fixes as likely to be kill sites. In total, 130 kills were identified to species, suggesting a mean kill rate of approximately 3.3 ± 0.3 (SE) kills/month per adult male leopard, which is higher than reported by most previous studies. The leopards varied considerably in the time they spent outside the national park; only 1 individual appeared to subsist mainly by raiding livestock. The availability of medium-sized ungulates at adequate densities is likely to be important for future leopard conservation efforts. The management of problem individuals also may promote coexistence of humans and leopards, even in prey-rich areas.

The click beetles (Elateridae) of Sonora, Mexico reported here are based on published historical records and recent sampling efforts in discrete Sky Island mountain ranges in the Madrean Archipelago north of the Sierra Madre Occidental.
