Future of Thailand's captive elephants: commentary on Baker & Winkler on elephant rewilding

Removal from natural habitat and commodification as private property compromise elephants’ broader societal value. Although we support Baker & Winkler’s (2020) plea for a new community-based rewilding conservation model focused on mahout culture, we recommend an expanded co-management approach to complement and enhance the regional elephant conservation strategy with additional local community stakeholders and the potential to extend across international borders into suitable elephant habitat. Holistic co-management approaches improve human wellbeing and social cohesion, as well as elephant wellbeing, thereby better securing long-term survival of Asian elephants, environmental justice, and overall sustainability

Effects of social disruption in elephants persist decades after culling.

BACKGROUND Multi-level fission-fusion societies, characteristic of a number of large brained mammal species including some primates, cetaceans and elephants, are among the most complex and cognitively demanding animal social systems. Many free-ranging populations of these highly social mammals already face severe human disturbance, which is set to accelerate with projected anthropogenic environmental change. Despite this, our understanding of how such disruption affects core aspects of social functioning is still very limited. RESULTS We now use novel playback experiments to assess decision-making abilities integral to operating successfully within complex societies, and provide the first systematic evidence that fundamental social skills may be significantly impaired by anthropogenic disruption. African elephants (Loxodonta africana) that had experienced separation from family members and translocation during culling operations decades previously performed poorly on systematic tests of their social knowledge, failing to distinguish between callers on the basis of social familiarity. Moreover, elephants from the disrupted population showed no evidence of discriminating between callers when age-related cues simulated individuals on an increasing scale of social dominance, in sharp contrast to the undisturbed population where this core social ability was well developed. CONCLUSIONS Key decision-making abilities that are fundamental to living in complex societies could be significantly altered in the long-term through exposure to severely disruptive events (e.g. culling and translocation). There is an assumption that wildlife responds to increasing pressure from human societies only in terms of demography, however our study demonstrates that the effects may be considerably more pervasive. These findings highlight the potential long-term negative consequences of acute social disruption in cognitively advanced species that live in close-knit kin-based societies, and alter our perspective on the health and functioning of populations that have been subjected to anthropogenic disturbance

A Critical Review of Lion Research in South Africa: The Impact of Researcher Perspective, Research Mode, and Power Structures on Outcome Bias and Implementation Gaps

Understanding the state of research, and its effectiveness, in a predominantly Life Sciences sphere, requires an assessment of knowledge growth dynamics, and the associated scientific and bibliometric impacts. We aim to create and evaluate, in a systematic review process, a macro-structure of the science generated in lion research in South Africa (SA) from 1990 to 2018. First, we classified the evidence architecture of lion research data extracted from the Web of Science Core Collection. Then, we identified prominent features that the datasets reveal in terms of authorship and ownership, as defined by first author affiliation and geographical location. Fifteen sub-disciplines were identified to characterize the topics. From 2000 onwards, multidisciplinary and interdisciplinary contributions started to emerge, catering for research problems defined at the interface of the academic-practitioner domains. These included social and economics components, and were aligned with conservation framings that seek to evaluate conservation within market-based vs. people-based approaches. Study areas were concentrated within SA (61.8%) and the remainder was either conducted in the rest of Africa (22.9%), or in various combinations of geographical focus. Author affiliation indicated that 63.1% of first authors had a South African affiliation. The rest of Africa was poorly represented at 2.4%. The majority (57.1%) of the first authors was male, but from 2014 to 2018, female researchers outnumbered males; however, male first authors continued to be cited more frequently. Furthermore, we provide a systemic analysis of the way in which research contributes to lion conservation. Overall, three voices dominate this area. Firstly, Mode 1 research has been driving research output in a “vicious circle,” motivated by researchers' quest for accumulating academic rewards. Secondly, the citation impact shows a gender disparity against the recognition of female researchers. Lastly, a power imbalance against authors from the rest of Africa became apparent, whereby their role is mainly shaped toward being team contributors. This research shows that effective conservation requires appropriate knowledge to be generated, and this to be effectively translated into practical applications, while considering all perspectives in order to provide the opportunity for balanced contributions and influences. Imbalances such as the ones revealed above are likely to prevail more broadly

Social media reveal that charismatic species are not the main attractor of ecotourists to sub-Saharan protected areas

Charismatic megafauna are arguably considered the primary attractor of ecotourists to sub-Saharan African protected areas. However, the lack of visitation data across the whole continent has thus far prevented the investigation of whether charismatic species are indeed a key attractor of ecotourists to protected areas. Social media data can now be used for this purpose. We mined data from Instagram, and used generalized linear models with site- and country-level deviations to explore which socio-economic, geographical and biological factors explain social media use in sub-Saharan African protected areas. We found that charismatic species richness did not explain social media usage. On the other hand, protected areas that were more accessible, had sparser vegetation, where human population density was higher, and that were located in wealthier countries, had higher social media use. Interestingly, protected areas with lower richness in non-charismatic species had more users. Overall, our results suggest that more factors than simply charismatic species might explain attractiveness of protected areas, and call for more in-depth content analysis of the posts. With African countries projected to develop further in the near-future, more social media data will become available, and could be used to inform protected area management and marketing.Peer reviewe

Identification of policies for a sustainable legal trade in rhinoceros horn based on population projection and socioeconomic models

Between 1990 and 2007, 15 southern white (Ceratotherium simum simum) and black (Diceros bicornis) rhinoceroses on average were killed illegally every year in South Africa. Since 2007 illegal killing of southern white rhinoceros for their horn has escalated to >950 individuals/year in 2013. We conducted an ecological-economic analysis to determine whether a legal trade in southern white rhinoceros horn could facilitate rhinoceros protection. Generalized linear models were used to examine the socioeconomic drivers of poaching, based on data collected from 1990 to 2013, and to project the total number of rhinoceroses likely to be illegally killed from 2014 to 2023. Rhinoceros population dynamics were then modeled under 8 different policy scenarios that could be implemented to control poaching. We also estimated the economic costs and benefits of each scenario under enhanced enforcement only and a legal trade in rhinoceros horn and used a decision support framework to rank the scenarios with the objective of maintaining the rhinoceros population above its current size while generating profit for local stakeholders. The southern white rhinoceros population was predicted to go extinct in the wild <20 years under present management. The optimal scenario to maintain the rhinoceros population above its current size was to provide a medium increase in antipoaching effort and to increase the monetary fine on conviction. Without legalizing the trade, implementing such a scenario would require covering costs equal to approximately $147,000,000/year. With a legal trade in rhinoceros horn, the conservation enterprise could potentially make a profit of$717,000,000/year. We believe the 35-year-old ban on rhinoceros horn products should not be lifted unless the money generated from trade is reinvested in improved protection of the rhinoceros population. Because current protection efforts seem to be failing, it is time to evaluate, discuss, and test alternatives to the present policy.Peer reviewe

Local government response to urban biodiversity conservation challenges within a global biodiversity hotspot

Introduction: The post 2020 Global Biodiversity Framework advocates for a whole-of-government and whole-of-society approach to address the global biodiversity crisis, with increasing calls for local governments to play a more active role in biodiversity conservation. We present a local government led examination of tools aimed at increasing biodiversity protection, management, and ecosystem restoration in the City of Durban, located in a global biodiversity hotspot.Methods: Using analytical frameworks and local government data, we assessed the efficacy of tools applied, and identified barriers and potential enablers to improve conservation outcomes.Results: We confirmed areas of success in the development of fit-for-purpose town planning tools that have contributed toward avoided loss of biodiversity, and the implementation of tools that have increased the protection of important biodiversity sites. Development of land management and restoration functions have further advanced conservation outcomes through restored ecological processes, and improved management of threats. Despite positive contributions to biodiversity conservation, several challenges persist, including unequal biodiversity protection and investment in relation to local population socio-economic status, cross-sectorial barriers, governance silos, and inadequate incentives for protection and management. Increasing biodiversity conservation on landholdings under traditional and private land tenure represents an important next step for the City. Upscaling of successful management tools, improving financial incentives for landowners, and adopting a more community centered approach to conservation governance, represent key opportunities for the City.Discussion: We emphasize the important role that a local government can play in contributing toward broader biodiversity goals and identify opportunities and challenges in the development and application of biodiversity conservation tools at the local government scale, through the lenses of governance, equity and justice, and inclusivity.</p

The value of urban and peri-urban conservation efforts within a global biodiversity hotspot

Background: Systematic conservation planning (SCP) is a key tool in conservation prioritisation. It has recently been applied within the eThekwini Municipal Area (EMA), South Africa, a rapidly developing metro located within a biodiversity hotspot. Most vegetation types within this region are threatened, yet have received limited scientific attention. Objectives: To assess forb biodiversity of coastal and near-coastal grasslands and contextualise potential drivers of species variation to the EMA context. Method: We quantified forb species richness, frequency and species composition, determined the variation of these amongst plots and sites, and assessed which variables were responsible for this variation. Results: Site forb species richness ranged from 33 to 84 species per site, with the most frequent species differing across the seven sites. Beta diversity was higher across than within sites. Distance to the closest traditional medicine market and site perimeter-to-area ratio were the greatest drivers of species richness, whilst altitude, aspect, mean temperature and rainfall seasonality were the main contributors to species composition patterns. Conclusion: SCP can use key environmental and climatic categories to improve selection of grasslands to maximise both species richness and variation in species composition. A more fine-scale systematic conservation plan will, in turn, provide a more robust basis for development decisions. The outcomes illustrate the importance of urban and peri-urban conservation efforts, including fine-scale conservation planning, in contributing to regional, national conservation targets

Human-elephant coexistence through aligning conservation with societal aspirations

Nature's contributions to people diminish when people are alienated from nature. We developed a framework to help support more sustainable people-nature interactions in the context of the conservation of African elephants (Loxodonta africana and L. cyclotis). Elephants are iconic, and ecologically, culturally, and socio-economically important, but are also competing and in conflict with people who still benefit little from elephant conservation. We demonstrate how this framework can be used to address challenges over elephant conservation and management, and help achieve human-elephant coexistence, by (i) balancing integrity of nature with social cohesion and human wellbeing, and (ii) moderating the use of nature through widely accepted values, aspirations, and rights. The framework provides mechanisms for policymakers and managers to improve existing community-based conservation initiatives, promotes equitable policies for elephant conservation, and can be applied to the conservation of other iconic species that pose management challenges.Peer reviewe

Step Process for Selecting and Testing Surrogates and Indicators of Afrotemperate Forest Invertebrate Diversity

BACKGROUND: The diversity and complexity of invertebrate communities usually result in their exclusion from conservation activities. Here we provide a step process for assessing predominantly ground-dwelling Afrotemperate forest invertebrates' (earthworms, centipedes, millipedes, ants, molluscs) potential as surrogates for conservation and indicators for monitoring. We also evaluated sampling methods (soil and litter samples, pitfall traps, active searching quadrats and tree beating) and temporal (seasonal) effects. METHODOLOGY/PRINCIPAL FINDINGS: Lack of congruence of species richness across taxa indicated poor surrogacy potential for any of the focus taxa. Based on abundance and richness, seasonal stability, and ease of sampling, molluscs were the most appropriate taxon for use in monitoring of disturbance impacts. Mollusc richness was highest in March (Antipodal late summer wet season). The most effective and efficient methods were active searching quadrats and searching litter samples. We tested the effectiveness of molluscs as indicators for monitoring by contrasting species richness and community structure in burned relative to unburned forests. Both species richness and community structure changed significantly with burning. Some mollusc species (e.g. Macroptychia africana) showed marked negative responses to burning, and these species have potential for use as indicators. CONCLUSIONS/SIGNIFICANCE: Despite habitat type (i.e., Afrotemperate forest) being constant, species richness and community structure varied across forest patches. Therefore, in conservation planning, setting targets for coarse filter features (e.g., habitat type) requires fine filter features (e.g., localities for individual species). This is especially true for limited mobility taxa such as those studied here. Molluscs have high potential for indicators for monitoring, and this requires broader study
