DART Mass spectrometry as a potential tool for the differentiation of captive-bred and wild lion bones.

In recent years lion bones have been legally traded internationally to Asian markets from captive bred sources in South Africa. There are also indications of increasing instances of illegal international trade in wild lion bones. The existence of parallel captive and wild supplies of lion bone are a cause of law enforcement concern regarding the potential for the laundering of illegally sourced bones through legal trade, and present a problem for the assessment of the conservation impact of wild lion bone trade due to the difficulty of determining what market-share wild and captive-bred lion bones account for. Captive-bred and wild lion bone are visually indistinguishable and no reliable method currently exists for distinguishing them. We present a preliminary study that explores the use of DART mass spectrometry as a method to differentiate between captive-bred and wild lion bones. We find that DART is able to differentiate between a batch of captive-bred South African lion bone and a batch of wild lion bone and suggest that DART mass spectrometry shows strong potential as a tool for the regulation and investigation of lion bone trade. Further testing is needed to prove the suitability of this technique. Therefore, we suggest that further research focuses on testing the capability of DART to differentiate between contemporary wild and captive-bred lion bone originating from South Africa, and attempts to identify chemical markers in bone that can be used as indicators of captive-bred origin

Monitoring compliance of CITES lion bone exports from South Africa

From 2008 to 2018, South Africa permitted the export of captive-bred African lion (Panthera leo) skeletons to Southeast Asia under CITES Appendix II. Legal exports rose from approximately 50 individuals in 2008 to a maximum of 1,771 skeletons in 2016, and has led to ongoing concerns over possible laundering of non-lion, multiple-source and wild-sourced bones. South Africa is required under its obligations to CITES to employ mechanisms for monitoring and reporting trade, and to limit the potential for illegal trade and laundering of lion and other large felid bones. Monitoring tools for legal trade are critical to compliance with CITES. Here we evaluate the CITES-compliance procedure implemented by South Africa for export of lion bones and identify six essential general points for consideration in the implementation of animal export quota compliance protocols. We provide specific insight into the South African lion bone export monitoring system through: i) outlining the protocols followed; ii) assessing the utility of cranial morphology to identify species; iii) evaluating skeleton consignment weight as a monitoring tool; and iv) presenting molecular (DNA) species assignment and pairwise-comparative sample matching of individuals. We describe irregularities and illicit behaviour detected in the 2017 and 2018 lion bone quotas. Notably, we report that the compliance procedure successfully identified and prevented the attempted laundering of a tiger (P. tigris) skeleton in 2018. We emphasise the utility of mixed-method protocols for the monitoring of compliance in CITES Appendix II export quota systems

Deep uncertainty, public reason, the conservation of biodiversity and the regulation of markets for lion skeletons

Public reason is a formal concept in political theory. There is a need to better understand how public reason might be elicited in making public decisions that involve deep uncertainty, which arises from pernicious and gross ignorance about how a system works, the boundaries of a system, and the relative value (or disvalue) of various possible outcomes. This article is the third in a series to demonstrate how ethical argument analysis—a qualitative decision-making aid—may be used to elicit public reason in the presence of deep uncertainty. The first article demonstrated how argument analysis is capable of probing deep into a single argument. The second article demonstrated how argument analysis can analyze a broad set of arguments and how argument analysis can be operationalized for use as a decision-making aid. This article demonstrates (i) the relevance of argument analysis to public reasoning, (ii) the relevance of argument analysis for decision-making under deep uncertainty, an emerging direction in decision theory, and (iii) how deep uncertainty can arise when the boundary between facts and values is inescapably entangled. This article and the previous two make these demonstrations using, as an example, the conservation and sustainable use of lions

The ethics of human-animal relationships and public discourse: A case study of lions bred for their bones

Conservation and natural resource management are increasingly attending the ethical elements of public decisions. Ethical considerations are challenging, in part, because they typically require accounting for the moral consideration of various human and nonhuman forms of life, whose interests sometimes conflict (or seem to conflict). A valuable tool for such evaluations is the formal analysis of ethical arguments. An ethical argument is a collection of premises, logically interrelated, to yield a conclusion that can be expressed in the form, “We ought to…” According to the rules of logic, a conclusion is supported by an argument if all its premises are true or appropriate and when it contains no mistaken inferences. We showed how the formal analysis of ethical arguments can be used to engage stakeholders and decision-makers in decision-making processes. We summarised the method with ten specific guidelines that would be applicable to any case. We illustrated the technique using a case study focused on captive-bred lions, the skeletons of which form part of an international trade to supply traditional medicine markets in Southeast Asia with felid bones. As a matter of public policy, the practice is a complicated nexus of concerns for entrepreneurial freedom, wildlife conservation, and the fair treatment of animals

Reflecting on the role of human‐felid conflict and local use in big cat trade

Illegal trade in big cat (Panthera spp.) body parts is a prominent topic in scientific and public discourses concerning wildlife conservation. While illegal trade is generally acknowledged as a threat to big cat species, we suggest that two enabling factors have, to date, been under‐considered. To that end, we discuss the roles of human‐felid conflict, and “local” use in illegal trade in big cat body parts. Drawing examples from across species and regions, we look at generalities, contextual subtleties, ambiguities, and definitional complexities. We caution against underestimating the extent of “local” use of big cats and highlight the potential of conflict killings to supply body parts

Guidelines for evaluating the conservation value of African lion (Panthera leo) translocations

As the top predator in African ecosystems, lions have lost more than 90% of their historical range, and few countries possess strong evidence for stable populations. Translocations (broadly defined here as the capture and movement of lions for various management purposes) have become an increasingly popular action for this species, but the wide array of lion translocation rationales and subsequent conservation challenges stemming from poorly conceived or unsuitable translocations warrants additional standardized evaluation and guidance. At their best, translocations fill a key role in comprehensive strategies aimed at addressing the threats facing lions and fostering the recovery of wild populations in their historic range. At their worst, translocations can distract from addressing the major threats to wild populations and habitats, divert scarce funding from more valuable conservation actions, exacerbate conflict with humans in recipient sites, disrupt local lion demography, and undermine the genetic integrity of wild lion populations in both source and recipient sites. In the interest of developing best practice guidelines for deciding when and how to conduct lion translocations, we discuss factors to consider when determining whether a translocation is of conservation value, introduce a value assessment for translocations, and provide a decision matrix to assist practitioners in improving the positive and reducing the negative outcomes of lion translocation.Grant from the European Union through IUCN Save Our Species, and the United States Fish and Wildlife Service.https://www.frontiersin.org/journals/conservation-scienceam2023Zoology and Entomolog

Elevation patterns of plant diversity and recent altitudinal range shifts in Sinai’s high mountain flora

Questions: Is there evidence of recent altitudinal range shifts in a hyper-arid Middle Eastern desert mountain flora? How do the directions of shift for upper and lower altitudinal range limits of plants vary? Location: Hyper-arid mountain desert, St Katherine Protectorate, South Sinai, Egypt. Method: We tested for shifts in both upper and lower altitudinal range limits by comparing a 1970s dataset of recorded species’ limits with recent surveys using altitudinal transects across 36 sites. Altitudinal limits between 63 paired upper-limit and 22 paired lower-limit values from the 1970s and 2014 were compared using paired t-tests; binomial tests were used to indicate the dominant direction of change. The upper and lower limits of 22 species were considered together to allow assessment of overall altitudinal range-size changes. In order to avoid the potential effect of yearly environmental fluctuations on the distributions of annual species, subsets of upper and lower limit shifts were taken for perennials, and trees and shrubs. Results: Our results show significant overall upslope shifts in mean upper altitudinal limits and significant overall downslope shifts in mean lower altitudinal limits. A majority of assessed species expanded their altitudinal ranges, but the responses of individual species varied. Since perennial herbs/graminoids, and trees and shrubs, show strong patterns of change, we suggest there has been a long-term shift in altitudinal range in South Sinai’s mountain flora. Greater research effort needs to be focussed upon the drivers of range-shift responses in arid regions

Wildlife collections of Royal Palace Museums in The West Region of Cameroon with a Focus on wildlife conservation

The royal palace museums of the Grassfields’ Kingdoms of West Region of Cameroon are well recognized for the preservation of culturally significant objects and practices. To date, the role of palace museums in wildlife conservation has received little consideration. Herein, a preliminary study into the animalbased artefacts of palace museums from a wildlife conservation perspective is presented. A total of 11 chiefdom palace museums in the West Region of Cameroon were surveyed and the animal species represented in their exhibitions recorded. Parts of 32 different animal species, including locally extinct large mammals such as lion, cheetah, chimpanzee, and elephant were found. The primary purpose for inclusion of specimens in palace museums was for preservation of culture. However, potential wildlife conservation focused uses to which palace museums may also put their collections are discussed herein. KeyWords: Grassfields, Bamileke, Bamoun, Culture, Education, Mammals.   Les musées du palais royal des royaumes des Grassfields de la région de l’Ouest Cameroun sont bien connus pour la préservation d’objets et de pratiques culturellement significatifs. À ce jour, le rôle des musées de palais dans la conservation de la faune a été peu pris en compte. Ici, une étude préliminaire des collections animales de ces musées du point de vue de la conservation de la faune est présentée. Onze musées de palais de chefferies de la région de l’Ouest Cameroun ont été étudiés et les espèces animales représentées dans leurs expositions ont été enregistrées. Des parties de 32 espèces animales différentes, y compris de grands mammifères  localement disparus comme le lion, le guépard, le chimpanzé et l’éléphant ont été découverts. Le but principal de l’inclusion de spécimens dans les musées du palais est la préservation de la culture. Cependant, les utilisations potentielles axées sur la conservation de la faune auxquelles les musées de palais peuvent également mettre leurs collections sont discutées ici. Mots clés
