A synthesis of wild animal-related trade laws in some of the world's most biodiverse countries

We examined the laws and legal provisions governing the commercial trade of terrestrial wild fauna across the trade chain in some of the world's megadiverse countries and how these relate to key animal welfare and conservation concerns. Over the past century, an increase in the quantity and complexity of laws related to commercial wildlife trade has been observed in the 11 focal countries examined. Our review identified 95 laws with 560 provisions adopted since 1910 across these countries. Surprisingly, the level of biological diversity in a country does not correlate with the extent of legislation addressing wildlife trade. Moreover, legislation is unevenly distributed across different stages of the wildlife trade chain, with more provisions on extraction and transportation compared to captive management. Notably, animal welfare considerations are relatively underrepresented in legislation related to wildlife trade, despite their broad implications for public health and economies. Urgent legislative action is needed to meet global biodiversity targets and respond to the challenges posed by the growing scale and complexity of the wildlife trade. Recommendations are made to streamline legislation, consider the legal status of wild animals, and address gaps in enforcement mechanisms. We conclude that alignment of national and international regulations is crucial for the effective protection of both wild animal populations and individual animals' welfare in the context of commercial trade. Further research is needed to assess the effectiveness of existing laws, bridge legal gaps, and address diverse concerns related to wildlife trade, including public health and the rights of local communities.

Visualisation and detection of latent DNA deposited by pangolin scales onto plastic packaging materials

We report on the detection and visualisation of latent DNA from pangolin scales deposited onto a plastic packaging material through the use of a nucleic acid staining dye. This latent DNA deposited by pangolin scales was subsequently isolated and analysed using DNA barcoding method. Pangolins are the most illegally traded mammalian species due to the demand for their scales and meat. The demand for their scales were mostly fuelled by its use in traditional medicines. The scales are usually packed into bags and transported globally via sea routes. This is the first report detailing the detection of trace latent DNA from processed wildlife products, on surfaces of bags that they were packaged in. Prior to this report, it was not known if the dried pangolin scales contained transferable quantities of biological material for DNA analyses. To address this, scales were removed from a roadkill Sunda pangolin (Manis javanica), processed by drying and packaged into one of five plastic bags. The presence of pangolin latent DNA was detected on the surface of the plastic bags and visualised using Diamond™ nucleic acid dye. Swabs were then used to recover the stained biological material from various locations in the five bags. The DNA was isolated and quantified using a newly designed quantitative PCR (qPCR) specific to M. javanica to amplify a fragment of the mitochondrial DNA cytochrome b gene. There was a positive correlation between the number of stained particles and DNA quantity, and a greater number of stained particles were found at the bottom of the bag than were found at the top. Conventional PCR targeting part of the cyt b gene amplified a product from all 30 samples taken from the bags and in all cases, sequence data generated matched that of the Sunda pangolin, as expected. All negative controls yielded no results. The method described here is the very first use of a nucleic acid staining dye to detect latent DNA from a mammalian species, other than humans, and highlights the opportunity for further use of Diamond™ nucleic acid dye in wildlife forensic science. It is anticipated that this method will be invaluable in retrieving latent DNA deposited by wildlife products from the environment in which they were contained, to determine the presence of these illegal wildlife products even when previously hidden, inaccessible, or no longer present physically. Further research is required to understand if the use on non-human mammalian wildlife species is feasible.

Examining the international bushmeat traffic in Belgium: A threat to conservation and public health

The carriage of bushmeat into the European Union is an infringement of EU Animal Health and Wildlife Trade legislation and poses a threat to biodiversity and public health. To explore the nature and scale of the international bushmeat trade, seized leaking luggage and passengers arriving at Brussels Zaventem airport from sub-Saharan Africa between 2017 and 2018 were searched for "meat" (bushmeat and livestock) by border control authorities. Visual identification, radiography and genetic analysis were applied to derive information from seized specimens, including at least ten CITES-listed species. We estimate that an average of 3.9 t of bushmeat is smuggled monthly through Brussels. The average consignment of meat seized per passenger was 2.8 kg and 4 kg of bushmeat or domestic livestock meat, respectively. The international trafficking of bushmeat is evidently active, yet penalties are rarely enforced; hence we provide suggestions to simplify law enforcement procedures.

The bear necessities: A sensitive qPCR assay for bear DNA detection from bile and derived products to complement wildlife forensic enforcement

Demand for bear bile, a prized component of traditional Asian medicines, threaten Asiatic and sun bear population sustainability. While laws exist to prevent poaching and trafficking of bear parts and derivatives, smuggling persists with demand extending to surrogate species, including American black bears (Ursus americanus). Mitochondrial DNA (mtDNA) sequencing can identify products putatively containing biological bear material but can be undermined by PCR inhibitors in bile and a lack of sensitivity at trace levels. Quantitative PCR (qPCR) assays can be used to distinguish between closely related target species, while concomitantly evaluating inhibition and false negative results in low quality/quantity DNA applications. Herein, we develop a multiplexed qPCR assay to detect and differentiate among bear species, including highly diluted bile samples mixed within liquors as common dilutants. The assay detects as little as 10 locus copies/reaction of bear DNA with 95% confidence, distinguishing among sun, Asiatic and American black bears. Demonstrating the sensitivity and applicability of this assay in context of current bile mixture recipes, dilutions of 1:5,000 bile with ethanol, red wine, and spirits, all yielded clear quantifiable detections, where our data suggests as little as 1 drop of bile per 750 mL bottle of alcohol would still exceed the limits of detection (e.g., 1:15000 dilution or <0.05 mL bile per 750 mL bottle). Overall, this study provides a rapid, sensitive, and specific test to identify and distinguish among bear species commonly used for bile production to aid wildlife enforcement applications.

Is social media the new wet market? Social media platforms facilitate the online sale of bushmeat in West Africa

Social media provides a platform for wildlife crime syndicates to access a global consumer-driven market. Whilst studies have uncovered the online trade in wildlife, the availability of wild meat (bushmeat) has not been assessed. To investigate the sale of wild meat online, we analysed 563 posts published between 2018 and 2022 from six West African Facebook pages selected using predetermined search criteria. Across 1511 images and 18 videos, we visually identified 25 bushmeat species-level taxa including mammals (six Rodentia, five Artiodactyla, three Carnivora, two Pholidota, one Primate, two Lagomorpha, one Hyracoidea), birds (three Galliformes) and reptiles (two Squamata), predominately advertised as smoked (63%) or fresh (30%) whole carcasses or portions. Among the species identified, 16% feature a status of concern on the International Union for Conservation of Nature (IUCN) Red List (Near Threatened to Endangered), 16% are listed on the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES; Appendix I and II) and 24% are either fully or partially protected by local legislation. Images were commonly used as propaganda rather than to display inventory, where additional taxa protected from game hunting in West Africa, such as hornbill, were exclusively listed in captions. The advertisement of these protected and vulnerable species on the surface web indicates weak local and international legislative enforcement. Comparatively, when the same search criteria were applied to the deep web browser Tor no results were generated, reinforcing the idea that bushmeat vendors have no need to hide their activities online. Despite local and international trade restrictions, the taxa advertised feature similarities with bushmeat seizures reported in Europe, alluding to the interconnectedness of the trade facilitated by social media. We conclude that enhanced policy enforcement is essential to combat the online sale of bushmeat and mitigate the potential biodiversity and public health impacts.

Unraveling the mystery of confiscated "jackal horns" in India using wildlife forensic tools

Internationally, illegal wildlife trade involves highly prized and charismatic species and their derivatives. At the same time, common or less known species and their parts are also encountered but receive less attention than charismatic species. Given the increasing demand for wildlife products in many parts of the world, profit, and short supply, many fake articles derived from domestic or wild animals are frequently encountered in the wildlife trade. Jackal horn (locally known as "Siyar or Gidar singhi") is one such fake item widely used in sorcery and other occult practices available through offline and online trading platforms within India. We used a combination of morphological, microscopic hair, and molecular approaches (Cyt b and 16 s rRNA genes) to reveal the true identity of confiscated "jackal horns" (n = 342). Detailed morphological study of the jackal horns showed that it varied in size, shape, color of hair, attachment material, and filling material. The microscopic hair and molecular approaches revealed that all the items sold as jackal horns were fake and made up of protected wild species and domestic animals. Our results confirm the use of the biological samples from few wild species protected under the Wild Life (Protection) Act, 1972, of India. Therefore, the law enforcement agencies are cautioned to get forensic opinions while dealing with such counterfeit items.

The scale of Nigeria's involvement in the trans-national illegal pangolin trade: Temporal and spatial patterns and the effectiveness of wildlife trade regulations

The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) prohibits commercial trans-national trade in pangolin specimens. However, African pangolins are continually trafficked to Asia for traditional medicine, with Nigeria considered a key hub. Using reported Nigeria-linked pangolin seizure data and interviews with Nigerian law enforcement officials, we a) characterised Nigeria's involvement in global pangolin trafficking January 2010-September 2021, particularly observing trafficking trends after pangolin's CITES Appendix I listing; b) estimated the minimum number of pangolins whose scales are in Nigeria-linked seizures January 2010-September 2021, and; c) assessed ongoing efforts within Nigeria to curb pangolin trafficking. Nigeria-linked seizures involved 190,407 kg of pangolin derivatives (99.9% scales) from a minimum of 799,343 pangolins (95% confidence interval; 625,944-996,353) of four species (see caveats in Methods). All shipments confiscated in transit were destined for Asia, with a rapid increase in the mass of maritime shipments over time. Furthermore, stockpiling of pangolin derivatives for overseas shipment is perhaps a prominent trafficking model in Nigeria. Nigeria's law enforcement efforts improved from 2017, the same year Nigeria apparently began playing a hub role. The impact of pangolin's CITES Appendix I listing on pangolin trafficking was unclear, as the marked rise in seizures from 2017 when the listing became effective, coincided with improvements in Nigerian law enforcement efforts. COVID-19-induced travel restrictions likely reduced trafficking activities in 2020 but activities may have fully resumed in 2021. This study provides new information to inform effective enforcement and policy formulation efforts to protect African pangolins.

Dataset of seized wildlife and their intended uses

The illegal wildlife trade (IWT) threatens conservation and biosecurity efforts. The Internet has greatly facilitated the trade of wildlife, and researchers have increasingly examined the Internet to uncover illegal trade. However, most efforts to locate illegal trade on the Internet are targeted to one or few taxa or products. Large-scale efforts to find illegal wildlife on the Internet (e-commerce, social media, dark web) may be facilitated by a systematic compilation of illegally traded wildlife taxa and their uses. Here, we provide such a dataset. We used seizure records from three global wildlife trade databases to compile the identity of seized taxa along with their intended usage (i.e., use-type). Our dataset includes c. 4.9k distinct taxa representing c. 3.3k species and contains c. 11k taxa-use combinations from 110 unique use-types. Further, we acquired over 45k common names for seized taxa from over 100 languages. Our dataset can be used to conduct large-scale broad searches of the Internet to find illegally traded wildlife. Further, our dataset can be filtered for more targeted searches of specific taxa or derived products.

The welfare of wildlife: an interdisciplinary analysis of harm in the legal and illegal wildlife trades and possible ways forward

Wildlife trade-both legal and illegal-is an activity that is currently the focus of global attention. Concerns over the loss of biodiversity, partly stemming from overexploitation, and the corona virus pandemic, likely originating from wildlife trade, are urgent matters. These concerns though centre on people. Only sometimes does the discussion focus on the wildlife traded and their welfare. In this article, we make the case as to why welfare is an important component of any discussion or policy about wildlife trade, not only for the interests of the wildlife, but also for the sake of humans. We detail the harm in the trade as well as the current welfare provisions, particularly in relation to the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES), which guide global transport and trade. There are a number of ways that the current approach to wildlife welfare could be improved, and we propose ways forward in this regard.

Scale of the issue: Mapping the impact of the COVID-19 lockdown on pangolin trade across India

Recent studies have linked COVID-19 induced restrictions to an increase in wildlife crime, with severe yet unknown implications for severely threatened taxa like pangolins. We analyze publicly available online seizure reports involving pangolins across India before (2018-2019) and during the pandemic (March-August 2020), using a longitudinal study design to estimate how lockdowns have impacted pangolin trade. Our analysis indicates a significant increase in seizures reported during the lockdown months of March to August 2020, in comparison to the same period in 2018 and 2019. We discuss the drivers behind this spike in pangolin trade and offer potential conservation measures.

Global dataset for seized and non-intercepted illegal cheetah trade (Acinonyx jubatus) 2010-2019

Cheetahs (Acinonyx jubatus) are a keystone predator of savanna systems in Africa, yet their populations have dramatically declined due to pressures such as human-wildlife conflict, loss of habitat, and most notably the illegal trade in live cheetah cubs as pets. We provide the most extensive dataset relevant to seized and non-intercepted illegal trade in live cheetahs and cheetah parts for the decade 2010-2019, spanning over 300 sources and 56 countries in Africa, the Middle East, Asia, Europe, Oceania and North America. It includes 1,884 individual incidents involving at least 4,000 cheetahs or cheetah parts or products likely or confirmed to breach national laws or CITES regulations. While the covert nature of illegal trade of any kind makes it extremely difficult to capture its true volume, we believe that the information contained in this dataset demonstrates the need for a more in-depth look into illegal cheetah trade, including sustainability assessments with emphasis in regions where cheetah populations are small and widely exploited, such as the Horn of Africa, as this dataset suggests. Ultimately, such actions could lead to improved enforcement and legal frameworks, and provide a guide for CITES actions involving international cooperation and demand reduction efforts.

Poacher-population dynamics when legal trade of naturally deceased organisms funds anti-poaching enforcement

Can a regulated, legal market for wildlife products protect species threatened by poaching? It is one of the most controversial ideas in biodiversity conservation. Perhaps the most convincing reason for legalizing wildlife trade is that trade revenue could fund the protection and conservation of poached species. In this paper, we examine the possible poacher-population dynamic consequences of legal trade funding conservation. The model consists of a manager scavenging carcasses for wildlife product, who then sells the product, and directs a portion of the revenue towards funding anti-poaching law enforcement. Through a global analysis of the model, we derive the critical proportion of product the manager must scavenge, and the critical proportion of trade revenue the manager must allocate towards increased enforcement, in order for legal trade to lead to abundant long-term wildlife populations. We illustrate how the model could inform management with parameter values derived from the African elephant literature, under a hypothetical scenario where a manager scavenges elephant carcasses to sell ivory. We find that there is a large region of parameter space where populations go extinct under legal trade unless a significant portion of trade revenue is directed towards protecting populations from poaching. The model is general and therefore can be used as a starting point for exploring the consequences of funding many conservation programs using wildlife trade revenue.

Addressing the illegal wildlife trade in the European Union as a public health issue to draw decision makers attention

The European Union is one of the most important markets for the trafficking of endangered species and a major transit point for illegal wildlife trade. The latter is not only one of the most important anthropogenic drivers of biodiversity loss, it also represents a growing risk for public health. Indeed, wildlife trade exposes humans to a plethora of severe emerging infectious diseases, some of which have contributed to the most dramatic global pandemics humankind has endured. Illegal wildlife trade is often considered as a problem of developing countries but it is first and foremost an international global business with a trade flow from developing to developed countries. The devastating effects of the ongoing SARS-CoV-2 outbreak should thus be an unassailable argument for European decision makers to change paradigm. Rather than deploying efforts and money to combat novel pathogens, mitigating the risk of spreading emerging infectious diseases should be addressed and be part of any sustainable socioeconomic development plan. Stricter control procedures at borders and policies should be enforced. Additionally, strengthening research in wildlife forensic science and developing a network of forensic laboratories should be the cornerstone of the European Union plan to tackle the illegal wildlife trade. Such proactive approach, that should further figure in the EU-Wildlife Action Plan, could produce a win-win situation: the curb of illegal wildlife trade would subsequently diminish the likelihood of importing new zoonotic diseases in the European Union.

Development and characterization of 20 polymorphic microsatellite markers for the white-bellied pangolin Phataginus tricuspis (Mammalia, Pholidota)

Pangolins, or scaly anteaters, have recently been flagshiped as one of the most illegally traded mammals, and as a corollary, as potential intermediate hosts at the origin of the COVID-19 pandemic. In order to improve the traceability of their trade, we developed 20 polymorphic microsatellite loci for the white-bellied pangolin (Phataginus tricuspis), the species most frequently found on African bushmeat markets. We genotyped 24 white-bellied pangolins from the Douala market, Cameroon, originating from the Ebo forest c. 75 km north-east of Douala. The number of alleles per locus ranged from 4 to 12 (mean = 6.95), and mean observed and expected heterozygosities were 0.592 (0.208-0.875) and 0.671 (0.469-0.836), respectively. Genetic diversity was higher than that cross-estimated from microsatellite loci developed for other species of pangolins. Two loci deviated from Hardy-Weinberg equilibrium and two loci showed linkage disequilibrium. Genetic variance (PCoA) was increased with the addition of 13 pangolins of unknown origin, possibly suggesting that the Douala market is fed from differentiated source populations of white-bellied pangolins. Each of the 37 individuals had a unique multilocus genotype. The unbiased probability of identity (uPI) and the probability of identity among siblings (PIsibs) were both very low (uPI = 8.443 e-21; PIsibs = 1.011 e-07). Only five microsatellite loci were needed to reach the conservative value of PIsibs < 0.01, overall indicating a powerful discriminating power of our combined loci. These 20 newly developed microsatellite loci might prove useful in tracing the local-to-global trade of the white-bellied pangolin, and will hopefully contribute to the DNA-assisted implementation of future conservation strategies at reasonable costs.

Bear bile use at the intersection of maternal health in Cambodia

BACKGROUND

The consumption of bear gallbladders and bear bile in Southeast Asia is a persistent threat to bear populations. As part of a larger effort to understand the characteristics of bear part consumption in Cambodia, we uncovered a consumer base of women seeking treatment for post-partum and uterine ailments.

METHODS

To better understand this aspect of consumption, we interviewed 122 women in seven different provinces in Cambodia, probing into the motivations and influences for using bear bile, as well as what types of ailments Cambodian women use it for.

RESULTS

We found that it is generally used by young or expecting mothers, and for such issues as post-partum "fatigue" (toas in Khmer), which could encompass post-partum depression. A desire to be supported by kin networks seems to facilitate the continued use of bear gallbladder and bile for these purposes.

CONCLUSIONS

We suggest that efforts to reduce consumption should focus on encouraging older kin to change their means of support to Western/biomedical and by extension non-wildlife alternatives.

Luxury Fashion Wildlife Contraband in the USA

The fashion industry is one of the largest markets for illegal wildlife products. This study examined US luxury fashion-related wildlife seizures made between 2003 and 2013 to better guide detection, enforcement, and policy. The findings of this study indicate that the number of incidents has increased over the 11-year period, while the number of associated items seized has decreased over this time. Of these seizures, nearly 88% were produced goods. A small proportion of genera made up the majority of seizures, with reptiles in particular accounting for 84% of incidents. Over half of all wildlife was wild-caught and was exported from eight countries. Based on these findings, it is suggested that policy be enacted relating specifically to the use of exotic leathers and furs, and that situational crime prevention alongside commitments to sustainability from fashion brands be used to reduce illegal imports and improve industry sustainability.

Fostering of a wild, injured, juvenile by a neighbouring group: implications for rehabilitation and release of Barbary macaques confiscated from illegal trade

Illegal live trade is one of the greatest threats to endangered Barbary macaques. Since trade focuses on young and Barbary macaques show extensive alloparental care, rehabilitation and release into wild foster groups is a promising strategy to free space in sanctuaries to allow continued confiscations, improve individual welfare, minimize captive care costs, and reinforce wild populations. However, little documentation exists on Barbary macaque releases and the age at which released macaques would be accepted by foster groups is unknown. Here, I report on a wild, nearly 3-year-old Barbary macaque male that was separated from his group after serious injury from a car collision. A neighbouring group found the distressed juvenile 2 days later, approached, groomed, and affiliated with him, and accepted him into the group. He remained with the foster group for 4 months until returning to his natal group. This observation challenges concerns that only infants and young juveniles may be accepted into non-natal groups, suggesting that even older confiscated juveniles could be candidates for release. This also adds to the literature on behavioural responses to distressed and injured individuals, demonstrating the capacity of wild monkeys to exhibit affiliative behaviours even towards unfamiliar distressed conspecifics, providing a rare example of potential consolation of an unknown individual. As so little documentation currently exists on the acceptance of Barbary macaques into wild foster groups, this observation provides valuable information for developing rehabilitation and release strategies for confiscated individuals, which can be critical for continuing to fight illegal trade of this endangered species.

Polymorphic microsatellite loci and partial mitogenome for the Chestnut-bellied Seed-finch Sporophila angolensis (Aves, Passeriformes) using next generation sequencing

Brazil is one of the major contributors to international trade in wildlife and species of the bird genus Sporophila are currently under threat due to illegal trade. Microsatellite loci and mitochondrial DNA constitute important molecular markers for population genetics studies and parentage analyses, and hold great potential to help authorities manage illegal trafficking and control commercial breeders. We describe and characterize 19 polymorphic microsatellite loci and recover part of the mitochondrial genome for Sporophila angolensis using massive parallel sequencing with the Illumina platform. DNA sequencing resulted in a dataset with 2,379,295 paired reads, of which 392 were mapped to the mitogenome of S. maximiliani, resulting in a partial mitogenome of 16,785 bp for S. angolensis. The microsatellite search identified a total of 4737 loci, from which 27 primer pairs were tested on 24 individuals of unknown geographic origin. Nineteen of the 27 loci were successfully amplified and exhibited high levels of genetic variation, with a mean of 11.2 alleles per locus, a mean observed heterozygosity of 0.588 and a mean expected heterozygosity of 0.852. About half of the loci showed significant evidence for the presence of a null allele and significant deviation from Hardy-Weinberg equilibrium; the remaining eight loci had high paternity exclusion probabilities and low identity probabilities. The high levels of polymorphism for these loci, as well as their high paternity exclusion probability and low identity probability, indicate that they hold potential for parentage analyses and population genetics studies of S. angolensis.

DNA based method for determining source country of the short beaked echidna (Tachyglossus aculeatus) in the illegal wildlife trade

The illegal trade in wild animals being sold as 'captive bred' is an emerging issue in the pet and zoo industry and has both animal welfare and conservation implications. DNA based methods can be a quick, inexpensive, and definitive way to determine the source of these animals, thereby assisting efforts to combat this trade. The short beaked echidna (Tachyglossus aculeatus) is currently one of the species suspected to be targeted in this trade. As this species is distributed throughout Australia and in New Guinea (currently comprising of five recognised sub-species), this project aimed to develop a DNA based method to definitively determine the source country of an echidna and explore the use of non-invasive sampling techniques. Here we use non-invasively sampled echidna quills and demonstrate the extraction of mitochondrial DNA and amplification of a region of the mitochondrial genome. Phylogenetically informative markers for analysis of a 322bp segment of the D-loop region were developed, and subsequently validated, using animals with known source locations allowing us to reliably distinguish between echidnas from New Guinea, and Australia. This research presents the first validated forensic protocols for short beaked echidnas and will be an integral tool in understanding the movement of animals in this emerging trade.

An internationally standardized species identification test for use on suspected seized rhinoceros horn in the illegal wildlife trade

Rhinoceros (rhino) numbers have dwindled substantially over the past century. As a result, three of the five species are now considered to be critically endangered, one species is vulnerable and one species is near-threatened. Poaching has increased dramatically over the past decade due to a growing demand for rhino horn products, primarily in Asia. Improved wildlife forensic techniques, such as validated tests for species identification of seized horns, are critical to aid current enforcement and prosecution efforts and provide a deterrent to future rhino horn trafficking. Here, we present an internationally standardized species identification test based on a 230 base pair cytochrome-b region. This test improves on previous nested PCR protocols and can be used for the discrimination of samples with <20pg of template DNA, thus suitable for DNA extracted from horn products. The assay was designed to amplify water buffalo samples, a common 'rhino horn' substitute, but to exclude human DNA, a common contaminant. Phylogenetic analyses using this partial cytochrome-b region resolved the five extant rhino species. Testing successfully returned a sequence and correct identification for all of the known rhino horn samples and vouchered rhino samples from museum and zoo collections, and provided species level identification for 47 out of 52 unknown samples from seizures. Validation and standardization was carried out across five different laboratories, in four different countries, demonstrating it to be an effective and reproducible test, robust to inter laboratory variation in equipment and consumables (such as PCR reagents). This is one of the first species identification tests to be internationally standardized to produce data for evidential proceedings and the first published validated test for rhinos, one of the flagship species groups of the illegal wildlife trade and for which forensic tools are urgently required. This study serves as a model for how species identification tests should be standardized and disseminated for wildlife forensic testing.
