Research on Prediction of Illegal Wildlife Trade Based on PCA and Multiple Linear Regression

Illegal wildlife trade is a long-standing issue, exerting negative impacts over national economies, regional security, and even global ecosystems. Governments worldwide and numerous environmental and animal protection organizations have been deeply engaged in addressing this issue for many years. Historically, there has been a lack of a quantifiable model to analyze the impact of implementing wildlife monitoring and conservation projects using drones on illegal wildlife trade.In this paper, we primarily propose an Illegal Wildlife Trade Prediction Model. By integrating four secondary indicators related to wildlife trade with the aforementioned 16 indicators, we reduced them to four primary indicators. The methodological tests confirmed their strong correlation, and multiple regression analysis was used to predict illegal wildlife trade, thereby verifying the project's effectiveness. Innovatively, we established a model to measure the probability of project completion, combining data from model predictions, resulting in an approximate completion probability of 60%. In conducting a project sensitivity analysis, we also developed a new model to perturb the three primary indicators, predicting the project's final outcome under random fluctuation of indicators, with variation rates as low as 0.34%, 0.98%, and 1.22%, indicating the project's stability.

Discrimination of ivory from extant and extinct elephant species using Raman spectroscopy: A potential non-destructive technique for combating illegal wildlife trade.

The use of elephant ivory as a commodity is a factor in declining elephant populations. Despite recent worldwide elephant ivory trade bans, mammoth ivory trade remains unregulated. This complicates law enforcement efforts, as distinguishing between ivory from extant and extinct species requires costly, destructive and time consuming methods. Elephant and mammoth ivory mainly consists of dentine, a mineralized connective tissue that contains an organic collagenous component and an inorganic component of calcium phosphate minerals, similar in structure to hydroxyapatite crystals. Raman spectroscopy is a non-invasive laser-based technique that has previously been used for the study of bone and mineral chemistry. Ivory and bone have similar biochemical properties, making Raman spectroscopy a promising method for species identification based on ivory. This study aimed to test the hypothesis that it is possible to identify differences in the chemistry of mammoth and elephant ivory using Raman spectroscopy. Mammoth and elephant tusks were obtained from the Natural History Museum in London, UK. Included in this study were eight samples of ivory from Mammuthus primigenius, two samples of carved ivory bangles from Africa (Loxodonta species), and one cross section of a tusk from Elephas maximus. The ivory was scanned using an inVia Raman micro spectrometer equipped with a x50 objective lens and a 785nm laser. Spectra were acquired using line maps and individual spectral points were acquired randomly or at points of interest on all samples. The data was then analysed using principal component analysis (PCA) with use of an in-house MATLAB script. Univariate analysis of peak intensity ratios of phosphate to amide I and III peaks, and carbonate to phosphate peaks showed statistical differences (p<0.0001) in the average peak intensity ratios between Mammuthus primigenius, Loxodonta spp. and Elephas maximus. Full width at half maximum hight (FWHM)analysis of the phosphate peak demonstrated higher crystal maturity of Mammuthus primigenius compared to living elephant species. The results of the study have established that spectra acquired by Raman spectroscopy can be separated into distinct classes through PCA. In conclusion, this study has shown that well-preserved mammoth and elephant ivory has the potential to be characterized using Raman spectroscopy, providing a promising method for species identification. The results of this study will be valuable in developing quick and non-destructive methods for the identification of ivory, which will have direct applications in archaeology and the regulation of international trade.

Forensic genetics associated with hair analysis as a tool for jaguar (Panthera onca) identification

Animal smuggling and illegal wildlife trade comprise one of the most common crimes being committed on an international level. This action can affect biodiversity and most certainly increases the risk of extinction of several endangered species. Wildlife taxonomic identification is becoming routine to forensic experts. The aim of this study was to identify a possible jaguar sample (Panthera onca Linnaeus, 1958) from legal evidence using hair morphology and mitochondrial DNA (mtDNA) to help in an official animal identification. Scanning and optical microscope images of hair samples were used to compare diagnostic characteristics of felines to reference studies. A preserved region, (cytochrome oxidase subunit 1 (COI)), from mtDNA was sequenced and compared to a DNA database (GenBank) to perform genetic identification. Forensic genetic and hair analysis techniques combined positively identified the sample as jaguar. These methods can help practitioners and forensics experts to identify evidence collected in wildlife crimes suspected to involve jaguars.

Model for Evaluating the Impact of the Illegal Wildlife Trade

The calculation of the impact score of illegal wildlife trade is of great significance for the protection of wildlife. In order to accurately calculate the illegal wildlife trade impact score, this paper constructs the illegal wildlife trade impact (SEN) evaluation model based on the combined weighting method of hierarchical analysis, coefficient of variation method and CRITIC weighting method, and selects 11 second-level indexes from the three aspects of society, economy and nature. The model calculation shows that from 2009 to 2023, the scores of social, economic and natural develop in a decreasing trend from 73, 63 and 56, respectively.

Towards Effective Measures for Curbing the Illegal Wildlife Trade: A Comprehensive Approach with ARIMA Modeling and Responsible Party Evaluation

Illegal wildlife trade has become an urgent global problem that threatens global ecosystems, biodiversity and sustainable development. This problem requires us to propose comprehensive measures to significantly curb illegal wildlife trade.We used data from government work reports from 2014 to 2023 to establish an evaluation system for the responsible parties, and found that wildlife conservation is very important to the Chinese government using the AHP-Entropy weight method. We developed relevant measures to reduce illegal wildlife trade based on Citespace's literature research method. Then we collected public data from Chinese governmental departments from 2010 to 2023, and used ARIMA model to predict the future of the initiatives we developed to reduce illegal wildlife trade. By collecting public data from the China Wildlife Wildlife Enforcement Agency and fitting the state of wildlife conservation based on China's national conditions over the past 15 years, we evaluated the available resources and found that while the overall trend of the Chinese government can reduce illegal trade practices, the trend is not stable in the short term. China's wildlife protection agencies can continue to increase enforcement of this problem to better reduce the occurrence of illegal wildlife trade behavior.

What is the evidence that counter‐wildlife crime interventions are effective for conserving African, Asian and Latin American wildlife directly threatened by exploitation? A systematic map

Abstract Counter‐wildlife crime (CWC) interventions—those that directly protect target wildlife from illegal harvest/persecution, detect and sanction rule‐breakers, and interdict and control illegal wildlife commodities—are widely applied to address biodiversity loss. This systematic map provides an overview of the literature on the effectiveness of CWC interventions for conserving African, Asian and Latin American wildlife directly threatened by exploitation, including human–wildlife conflicts that trigger poaching. Following our systematic map protocol (Rytwinski, Öckerman, et al., 2021), we compiled peer‐reviewed and grey literature and screened articles using pre‐defined inclusion criteria. Included studies were coded for key variables of interest, from which we produced a searchable database, interactive map and structured heatmaps. A total of 530 studies from 477 articles were included in the systematic map. Most studies were from Africa and Asia (81% of studies) and focused on African and Asian elephants (16%), felids (14%) and turtles and tortoises (11%). Most evaluations of CWC interventions targeted wildlife products (rather than species) and the transfer of those products along the wildlife crime continuum (40% of cases). Population/species outcomes were most commonly measured via indicators of threat reduction (65% of cases) and intermediate outcomes (25%). We identified knowledge clusters where studies investigated the links between (1) patrols and other preventative actions to increase detection and population abundance and (2) information analysis and sharing and wildlife crime/trade levels. However, the effectiveness of most interventions was not rigorously evaluated. Most investigations used post‐implementation monitoring only (e.g. lacking a comparator), and no experimental designs were found. We identified several key knowledge gaps including a paucity of studies by geography (Latin America), taxonomy (plants, birds and reptiles), interventions (non‐patrol‐based CWC interventions) and outcomes (biological and the combination of biological and human well‐being outcomes). Our map reveals an opportunity to improve the rigour and documentation of CWC intervention evaluations, which would enable the evidence‐based selection of effective approaches to improve wildlife conservation and national security.

Indonesia's sustainable development goals in relation to curbing and monitoring the illegal wildlife trade

AbstractIndonesia has committed to implement the sustainable development goals (SDG) by 2030 including the ending trafficking of protected species and addressing the illegal wildlife demand and supply. As such, there is a need for long‐term data on wild animal trade and its contribution to the wider economy. We initiated a long‐term monitoring programme of live civet trade in wildlife markets (120 surveys, 2010–2023). Civets are traded to be kept as exotic pets and to produce civet coffee and are a proxy for other high‐profile wildlife. We recorded 2289 civets of six species, including ones with strict regulations in place. Despite the trade being illegal, and contra to Indonesia's commitments as part of the SDG to curb this trade, it remained remarkably stable over time (numbers, species, prices). As such, Indonesia is not meeting its SDG targets that are related to curbing illegal wildlife trade and illicit financial flows.

Spatial Modelling Habitat Suitability of Javan Langur (&lt;i&gt;Trachypithecus auratus&lt;/i&gt; É. Geoffroy Saint-Hilaire, 1812) in Bromo Tengger Semeru National Park (TNBTS), East Java

Javan Langur (T. auratus) is well-known as one of endemic primates from Java, Bali and Lombok Islands. The activities of land clearing, vegetation conversing, wild hunting and illegal wildlife trading are the main causes of the extinction of the Javan Langur. It can be used as an important issue for conservation action by making prediction maps of suitable habitat potential, especially for species facing a high risk of extinction in the wild. We were documenting an information about potential habitat for Javan langur using spatial suitability model in order to provide rigorous information as the basis for conservation activities of Javan langur in TNBTS. We used Landsat-8 TM image and geospatial data to support analysis as a representative of environmental parameters in order to develop the habitat model. We were using maximum entropy (MaxEnt) algorithm refers to Javan langur presence or absence. The results showed that the suitability of the Javan langur habitat in TNBTS has an excellent model accuracy level with an AUC (Area Under the Receiver Operating Characteristics) value of 0.964 and a standard deviation of 0.961. Parameters with the highest response values here are elevation, NDVI (Normalised Difference Vegetation Index) and temperatures.

Illegal wildlife trade: An analysis of carnivore products found in markets in Benin and Niger

West Africa is home to one of the largest protected area systems in Africa, the W-Arly- Pendjari (WAP) Complex, which provides a last refuge for many threatened carnivore species extirpated from most other protected areas in the region. However, rising global demand for wildlife products has increased concerns about the impacts of Illegal Wildlife Trade (IWT) on these species. To assess the extent of IWT, covert market surveys were conducted in Benin and Niger to identify wildlife products and derivatives coming from carnivore species (African civet, serval, caracal, lion, cheetah, leopard, and spotted hyena) suspected to be targeted by IWT. When possible, information about product origin was gathered to understand trading routes. Data were analysed to determine if products were available in markets due to their proximity to source populations or due to accessibility to trade and transport hubs. A variety of products from several threatened species, including multiple lion skins, were found in Benin and Niger. Products were found more frequently in markets near the WAP Complex and main trade and transport hubs. Sellers reported that a large majority of products originated from international trade, but some could also have been sourced from the WAP Complex. There was little evidence indicating that product availability was more affected by the distance to the WAP Complex than by the distance to international transport hubs, suggesting that trade was widespread across both countries. The study provides an evidence base and monitoring baselines to identify and assess interventions to address IWT and ultimately reduce illegal trafficking of wildlife.

Conservation genetics of the white-bellied pangolin in West Africa: A story of lineage admixture, declining demography, and wide sourcing by urban bushmeat markets.

During the last 40 years, the volumes of African pangolins feeding the illegal wildlife trade have dramatically increased. We conducted a conservation genetics survey of the most traded African species, the white bellied pangolin (WBP; Phataginus tricuspis), across three West African countries including Guinea, Côte d'Ivoire, and Ghana. Our study combining mitochondrial DNA sequencing and microsatellite genotyping is the first to reveal a wide pattern of admixture between two of the six mitochondrial lineages as previously delimited within WBP. We found a signature of isolation by distance but a lack of population genetic structuring, supporting the idea that WBP may have underestimated dispersal abilities. Levels of genetic diversity were low in West African lineages (WAfr and Gha) compared to Central Africa, reinforcing the picture of genetic pauperization shared by West African WBP. We observed a 85%-98% decline in the effective population size of WBP occurring c. 3200 to 400 ya, with current numbers (520-590) at the lower end of the conservative thresholds for minimum viable population size. The microsatellite markers were powerful enough to differentiate between individuals and identify replicated samples, confirming the utility of this approach in tracing the pangolin trade. Genetic diversity estimates confirmed that Yopougon, the main bushmeat market from Abidjan (Côte d'Ivoire), was fed by a large trade network as confirmed by vendors reporting 10 different sources situated 62-459 km away from the market. We conclude that WBP distributed in the Upper Guinean Block should be considered a single management unit of high conservation concern, as impacted by genetic diversity erosion, drastic decline in effective population size, and wide range sourcing for feeding urban bushmeat markets. Given the genetic admixture pattern detected within WBP from West Africa, we advocate for a multi-locus strategy to trace the international trade of the species.

US wildlife trade data lack quality control necessary for accurate scientific interpretation and policy application

AbstractInternational wildlife trade data are frequently used by government agencies, conservation organizations, and scientific researchers to study and protect species from overexploitation and prevent the spread of invasive species and introduction of zoonotic pathogens. Inaccurate data can lead to mistaken conclusions by researchers, the development of unsuccessful remedial conservation actions, and provide government officials with incorrect views of detrimental trade. The U.S. Fish and Wildlife Service (USFWS) maintains the world's most comprehensive national dataset of legal and illegal international wildlife trade recorded by individual shipments and species in its Law Enforcement Management Information System (LEMIS). Although the importance of LEMIS data is not to be understated, the errors and inconsistencies contained therein have not previously been adequately recognized or studied. Based on firsthand experiences with the creation and application of LEMIS data, this manuscript describes a variety of errors, biases, omissions, and an overall lack of data quality assurance. An independent audit of the LEMIS wildlife trade database and the service's policies, procedures, and protocols for managing this system is needed. Additional recommendations are also offered to develop better management standards and bring greater resources for managing LEMIS, asking the nongovernmental organization and intergovernmental organization user communities to play a role.

Joint detection of microsatellites and flanking sequences – SNPSTR markers for Athene noctua to fight illegal wildlife trade

Trade of wild-caught animals is illegal for many taxa and in many countries. Common regulatory procedures involve documentation and marking techniques. However, these procedures are subject to fraud and thus should be complemented by routine genetic testing in order to authenticate the captive-bred origin of animals intended for trade. A suitable class of genetic markers are SNPSTRs that combine a short tandem repeat (STR) and single nucleotide polymorphisms (SNPs) within one amplicon. This combined marker type can be used for genetic identification and for parentage analyses and in addition, provides insight into haplotype history. As a proof of principle, this study establishes a set of 20 SNPSTR markers for Athene noctua, one of the most trafficked owls in CITES Appendix II. These markers can be coamplified in a single multiplex reaction. Based on population data, the percentage of observed and expected heterozygosities of the markers ranged from 0.400 to 1.000 and 0.545 to 0.850, respectively. A combined probability of identity of 5.3 * 10−23 was achieved with the whole set, and combined parentage exclusion probabilities reached over 99.99%, even if the genotype of one parent was missing. A direct comparison of an owl family and an unrelated owl demonstrated the applicability of the SNPSTR set in parentage testing. The established SNPSTR set thus proved to be highly useful for identifying individuals and analysing parentage to determine wild or captive origin. We propose to implement SNPSTR-based routine certification in wildlife trade as a way to reveal animal laundering and misdeclaration of wild-caught animals.

Perlindungan Harimau Sumatera Menurut Convention On International Trade In Endangered Species Of Wild Fauna And Flora (Cites) 1963

Introduction: The illegal trade in protected animals is increasing in places where laws are not respected, as if they weren't there. This is reflected in the decrease in the number of wildlife and the increase in the number of legal and illegal wildlife traders whose criminals do not face severe sanctions. The number of Sumatran tigers is decreasing, reaching around 400 individuals. In various parts of Sumatra, these endangered and protected animals continue to be hunted and traded for their organs. Apparently, in the near future, they succeeded in capturing or blocking the Medan tiger skin trade.Purposes of the Research: This writing aims to know and understand the Regulations regarding the protection of endangered species based on the 1963 Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and the Implementation of CITES 1963 in Indonesia to protect the Sumatran Tiger.Methods of the Research: Normative research method with the type of research is qualitative analysis. The problem approach used is the statute approach, the conceptual approach and the case approach. The sources of legal materials used are Primary legal materials, Secondary legal materials, and Tertiary legal materials and are used as a technique for collecting legal materials, then processing and analyzing legal materials through methods of interpretation, harmonization, systematic and legal discovery.Results of the Research: The results of the study show that the arrangements regarding the protection of endangered species based on the 1963 Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) are that as a whole, CITES is a convention that applies as a general guide to regulate matters relating to trade of all kinds. Wild plants and animals that live in nature. Specifically regarding the protection of Sumatran tigers as implementation of CITES 1963 is the enactment of Presidential Decree No. 43 of 1978 concerning Ratifying the Convention On International Trade in Endangered Species of Wild Fauna and Flora, Law No. 5 of 1990 concerning Conservation of Natural Resources, Biology and Their Ecosystems, Regulations Government Number 8 of 1999 Utilization of Wild Plants and Animals, Minister of Forestry Regulation Number P.42/Menhut-II/2007 concerning Sumatran Tiger Conservation Plans and Actions.

Lessons in resilience from the illegal wildlife trade during COVID-19 lockdowns

The COVID-19 pandemic was an unexpected event with far-reaching long-term economic, political, and social consequences, entailing disruptive changes with potentially existence- and livelihood threatening consequences. Lessons in resilience from illegal economies such as the illegal wildlife trade could help society better cope with harms and risk from global environmental change. We critically review the Frictions and Flows framework and the case of the illegal wildlife trade—a globally distributed form of nature crime—in South Africa, Tanzania, and Zambia—countries with different responses to the COVID-19 pandemic. Diverse frictions and flows were, and continue to be, documented in the illegal wildlife economies of each country through and after pandemic lockdowns, demonstrating resilience, adaptability, and innovation. We point to market features and characteristics prevalent in the anthroposphere that appear to render actors and markets more resilient, shock-resistant, and flexible. Without advocating for operating outside the rule of law and with overt recognition for the destructive impacts of illicit trades on sustainable development, political stability, and global security, we identify three observations relevant to resilience and global environmental change that scientists of the total environment may be critically missing.

Wildlife farming: Balancing economic and conservation interests in the face of illegal wildlife trade

Abstract Demand for wildlife and their products continues to grow, often despite increasingly militarised regulation and consumer awareness campaigns. We review the sustainability, legality and feasibility of wildlife farming of animals, as a potential conservation tool to ensure the development of an equitable and sustainable trade model. While there are some positive examples of well‐managed wildlife farming in trade, we identify common themes of misuse including the intentional mislabelling of wild‐caught specimens in global trade and the use of wild‐caught individuals to supplement captive stocks. We also highlight the frequent failure to incorporate biological data into management strategies, resulting in the widespread use of species with potentially unfavourable life history traits, which constrain the economic and biological sustainability of wildlife farming programmes. We develop a structured decision framework to aid the examination of when wildlife farming may most benefit or hinder species conservation. Synthesis and applications. Key opportunities include developing species suitability assessments and removing barriers to legitimate participation with wildlife farming among poor, rural communities. In the absence of management strategies that address the issues of species suitability and accessibility, wildlife farming will continue to place significant strain on wild populations while failing to provide conservation value and sustainable economic returns.

The Influence of Tanning Chemical Agents on DNA Degradation: A Robust Procedure for the Analysis of Tanned Animal Hide-A Pilot Study.

Illegal wildlife trade is currently on the rise, and it is becoming one of the most lucrative crime sectors. The rarer the species, the higher the demand. Wildlife trade falls under international regulations, such as the CITES convention. Proving that this convention has been violated is a complex process and can be very difficult to do. DNA analysis methods remain (in many cases) the only way to determine whether a certain specimen originated from a protected animal species, a specific individual, or a species in which it is legal to trade. Tanned animal hides are a specific type of specimen. With this type of biological material, obtaining amplifiable DNA is often difficult. This pilot study aimed to map the effect of the chemicals used in the tanning process on the degradation of the DNA yielded from such samples. The DNA was quantified using two different approaches: qPCR and Qubit fluorometry. The degree of DNA fragmentation was assessed by determining the degradation index. The results indicate that reagents containing chromium have the greatest influence on DNA degradation. However, by using the presented protocol, enough amplifiable DNA can be obtained from hides treated with aluminum-based reagents.

Avoiding novel, unwanted interactions among species to decrease risk of zoonoses.

Circumstances that precipitate interactions among species that have never interacted during their evolutionary histories create ideal conditions for the generation of zoonoses. Zoonotic diseases have caused some of the most devastating epidemics in human history. Contact among species that come from different ecosystems or regions creates the risk of zoonoses. In certain situations, humans are generating and promoting conditions that contribute to the creation of infectious diseases and zoonoses. These conditions lead to interactions between wildlife species that have hitherto not interacted under normal circumstances. I call for recognition of the zoonotic potential that novel and unwanted interactions have; identification of these new interactions that are occurring among wild animals, domestic animals, and humans; and efforts to stop these kinds of interactions because they can give rise to zoonotic outbreaks. Live animal markets, the exotic pet trade, illegal wildlife trade, human use and consumption of wild animals, invasive non-native species, releasing of exotic pets, and human encroachment in natural areas are among the activities that cause the most interactions among wild species, domestic species, and humans. These activities should not occur and must be controlled efficiently to prevent future epidemic zoonoses. Society must develop a keen ability to identify these unnatural interactions and prevent them. Controlling these interactions and efficiently addressing their causal factors will benefit human health and, in some cases, lead to positive environmental, ethical, and socioeconomic outcomes. Until these actions are taken, humanity will face future zoonoses and zoonotic pandemic.

Examining the Roles and Attitudes of the Local Community in Wildlife Conservation of Ethiopia

This short review summarizes the roles and behavioral responses of local communities towards wildlife conservation in Ethiopia. The inherent practices of local communities in their long‐held traditional and cultural setups give them an important role in conservation successes. Traditional wildlife conservation practices in Ethiopia are not well documented and have likely been heavily eroded due to changes in governmental regimes, each with different ideologies, the introduction of modern lifestyles and religions, and ethnic and cultural diversities. Local communities contribute a lot to wildlife conservation when they are allowed to participate in fighting illegal wildlife trafficking operations. The illegal wildlife trade (IWT) in Ethiopia is still a comparatively new phenomenon with a low scientific profile. The roles of local people both in the IWT and in prevention and conservation efforts remain undocumented, and research into these is at an early stage. Several studies have indicated the alienation of the local community and their subsequent antagonistic responses towards conservation efforts in different parts of Ethiopia. Eviction of indigenous people, benefit denial, unequal benefit sharing, and interactions with wildlife and human‐wildlife conflicts are the major factors fueling the resentment of local communities towards wildlife and their conservation. Thus, wildlife conservation in Ethiopia needs impartial studies and practical improvement to understand and address these human dimensions and inform more effective conservation and IWT prevention.

Relato de coccidiose em um trinca-ferro Saltator similis de vida-livre no Parque Nacional do Itatiaia no sudeste brasileiro

ABSTRACT: The green-winged saltator Saltator similis (d’Orbigny &amp; Lafresnaye, 1837) is a passerine bird highly valued by bird breeders and a target of illegal wildlife trafficking. Coccidian chromists are etiological agents of coccidiosis, which may be asymptomatic and enzootic in bird populations when environmental conditions are favorable. However, epizootic outbreaks with severe disease can occur due to environmental changes. In this context, this study reports a case of coccidiosis in a free-living juvenile specimen of S. similis captured at the Itatiaia National Park in southeastern Brazil. Typical clinical signs of coccidiosis were observed, and it was associated with greenish mucoid diarrhea containing a high density of coccidian oocysts. Three Isospora spp. were specifically identified in 14 fecal samples (fecal droplets) collected over two hours. Isospora saltatori (Berto, Balthazar, Flausino &amp; Lopes, 2008) had the highest density and positivity throughout most of the collection period. Finally, this paper discusses the importance of the continuous evaluation of the health of birds as bioindicators and their coccidian ecological biomarkers as one of the strategies for evaluating the conservation status of Itatiaia National Park.
