RESUMEN

We tested animals from wildlife trade sites in Laos for the presence of zoonotic pathogens. Leptospira spp. were the most frequently detected infectious agents, found in 20.1% of animals. Rickettsia typhi and R. felis were also detected. These findings suggest a substantial risk for exposure through handling and consumption of wild animal meat.

RESUMEN

The COVID-19 pandemic has exposed the inadequacy of China's legal protection of wildlife. Long-standing illegal wildlife trade in China and worldwide increases the risk of zoonotic infectious diseases. We sought to improve the understanding of China' legal system for the protection of wildlife, which has at its core the wildlife protection law, by systematically evaluating the laws and regulations of China's Wildlife Protection Framework. We examined how existing legal documents (e.g., the Wildlife Protection Law 2018) are directly or indirectly related to wildlife conservation. The inherent defects of wildlife protection legislation include a narrow scope of protection, insufficient public participation, and inconsistent enforcement among responsible agencies. Solutions to improve China's Wildlife Protection Law include expanding the legal protection of wildlife, and improving monitoring of wildlife protection. Strengthening legislation will be the basis for effective regulation of the use of wild animals. We advocate the establishment of a sound wildlife protection legal system for resolving conflicts between humans and wild animals and preventing zoonotic disease, such a system will have a profound impact on the sustainable development of China's wildlife resources.


Cambios en el Pensamiento Legislativo en China para Mejorar la Protección a los Animales Silvestres y la Salud Humana Resumen La pandemia de COVID-19 ha expuesto la insuficiencia de la protección legal de la fauna en China. El prolongado mercado ilegal de fauna en China y en todo el mundo incrementa el riesgo de enfermedades zoonóticas infecciosas. Buscamos mejorar el entendimiento del sistema legal de China para la protección de la fauna, el cual tiene como núcleo la ley de protección de fauna, mediante la evaluación sistemática de las leyes y regulaciones del Marco de Protección a la Fauna de China. Examinamos cómo los documentos legales existentes (p. ej.: la Ley de Protección de Fauna 2018) están relacionados directa o indirectamente con la conservación de la fauna. Los defectos inherentes de la legislación para la protección de fauna incluyen una visión reducida de la protección, una participación pública insuficiente y el cumplimiento inconsistente entre las agencias responsables. Las soluciones para mejorar la Ley de Protección de Fauna incluyen la expansión de la protección legal de fauna y el aumento al monitoreo de la protección de fauna. El fortalecimiento de la legislación será la base para la regulación efectiva del uso de animales silvestres. Abogamos por el establecimiento de un firme sistema legal de protección a la fauna para resolver los conflictos entre los humanos y los animales silvestres y también para prevenir las enfermedades zoonóticas. Dicho sistema tendrá un impacto profundo sobre el desarrollo sustentable de los recursos faunísticos de China.

RESUMEN

Illegal wildlife trade has been identified as a major source of global commerce of seahorses. The Convention on International Trade in Endangered Species of Wild Fauna and Flora listed the genus Hippocampus in Appendix II in 2004, when several countries that commercialized these species also banned transactions through domestic legislation, Peru being one of them. Nevertheless, since the 2004 ban was decreed in Peru, transactions have continued, including international commerce, as well confiscations of illegal seahorse Hippocampus ingens (Girard 1858) products. The authors reviewed three official government sources for information on seahorse trade in Peru, identifying differences in the reporting of the two agencies that monitor exports and imports of seahorses, likely due to non-standardized use of product categorization codes (Partidas Arancelarias). Confiscations reported by one of the agencies confirmed that illegal trade continued despite the ban and in similar amounts of what was exported by Peru before the ban (1053 kg confiscated in 2019 vs. 1460 kg exported in 2004, an estimated 437,888 and 607,067 seahorses, respectively). This review highlights gaps in seahorse conservation in Peru, which include research gaps (e.g., taxonomy, biology and use of habitats) as well as the identification of fisheries impact and improvements in by-catch reporting. This review also highlights areas for possible improvement in international trade (e.g., standardized descriptions of Partidas) that ultimately would allow the country to follow the Convention for Illegal Trade of Endangered Species regulations for seahorses.

RESUMEN

INTRODUCTION: In 2009, New York City (NYC) restricted the sale of flavoured tobacco products. We assessed product availability as a proxy for potential non-compliance by analysing discarded cigar, cigarillo and blunt wrap packages in New York City. METHODS: A discarded cigar package survey was conducted in 2016, in a stratified random sample of 94 block groups in NYC resulting in the collection of 886 discarded cigar packages. Each package was coded for brand name, flavour description (explicit and implicit) and size. FINDINGS: Overall, 19.2% of the cigar packages were explicitly flavoured. An additional 9.4% of the packages reflected implicit flavours. Explicit flavoured cigar packages were at increased odds of being found in Staten Island (adjusted OR (AOR)=3.96, 95% CI=1.66 to 9.46), in packaging size of two or three (AOR=8.49, 95% CI=4.24 to 17.02) or four or more (AOR=4.26, 95% CI=1.95 to 9.30). CONCLUSION: Nearly one out of three cigar packages were flavoured products suggesting a problematic level of non-compliance and continued availability. Potential non-compliance is likely fueled by licensed wholesalers and retailers who continue to sell restricted flavoured products. Some retailers may be unaware that implicitly named cigars are typically flavoured and are, therefore, illegal. This lack of awareness of implicit flavoured cigars may be exacerbated by NYC's lack of education or enforcement specific to implicitly flavoured tobacco products.

RESUMEN

The Red-cowled Cardinal (Paroaria dominicana) is an endemic passerine of the Caatinga biome in Brazil, and is one of the most traded passerines in the country. Illegal trade can have serious impacts on wild populations, such as reduced population sizes, the introduction of the species to areas outside their historical range or mixing individuals from different populations. Microsatellites constitute an important tool for population genetics and forensics studies, and hold great potential to help authorities manage illegal trafficking and inspect commercial breeders. We developed new microsatellite loci using massive parallel sequencing and characterized them in 23 seized Red-cowled Cardinals with unknown geographic origin. The DNA sequencing generated 2,068,684 paired-reads of which we identified 10,322 tri- to hexanucleotide loci. We selected 30 loci for amplification and polymorphism tests, of which 21 successfully amplified and 19 were polymorphic. The number of alleles ranged from 7 to 18 and the mean expected heterozygosity was 0.863. Six loci deviated from Hardy-Weinberg equilibrium probably due to null alleles and/or the Wahlund effect. Polymorphic loci in Hardy-Weinberg equilibrium showed low identity probability and high paternity exclusion probability. Our results indicate that this new set of microsatellite loci constitutes an important tool for both population genetic and forensic studies, with ultimate potential for assisting authorities in managing animal victims of illegal trafficking and the inspection of commercial breeders of the Red-cowled Cardinal.

RESUMEN

This work aimed to investigate the prevalence of Staphylococcus in wild birds seized in illegal trade and their antimicrobial resistance patterns. Cloacal samples were obtained from 109 wild birds apprehended in the street markets in Rio de Janeiro, Brazil. Staphylococcus spp. were phenotypically and genotypically identified, and resistance profile was evaluated according to Clinical and Laboratory Standards Institute guidelines and by polymerase chain reaction of mecA and blaZ genes. Staphylococcus was detected in 45·9% (50/109) of the cloacal swab samples, and 39 (78·0%) isolates were resistant to one or more of the nine antimicrobials tested and were also positive to mecA (12/39) or blaZ genes (14/39). High percentage of resistance was detected to ampicillin, oxacillin, cefoxitin, clindamycin and tetracycline, with the absence of resistance to vancomycin. Wild birds captured and submitted to captive stress conditions of illegal trade market of Brazil may have an important role as reservoirs of Staphylococcus spp. and its antimicrobial resistance mechanisms. The significance of this study is revealed by the zoonotic and pathogenic potential of staphylococci and that impact to public health and requires monitoring polices of wild birds health in tropical areas. SIGNIFICANCE AND IMPACT OF THE STUDY: The isolation of Staphylococcus species that are not commonly isolated from wild bird faeces, the relatively high proportion of strains showing degrees of resistance to ß-lactamics, lincosamides and tetracycline, and also the presence of mecA and blaZ genes that has been associated with multidrug phenotype reveal its public health relevance and zoonotic potential. Consequently, this represents an important route to transmission of this pathogen and its antimicrobial resistance mechanisms throughout national and international frontiers fostered by the illegal trade of wild animals and close contact with humans.

RESUMEN

Although most often considered independently, subsistence hunting, domestic trade, and international trade as components of illegal wildlife use (IWU) may be spatially correlated. Understanding how and where subsistence and commercial uses may co-occur has important implications for the design and implementation of effective conservation actions. We analyzed patterns in the joint geographical distribution of illegal commercial and subsistence use of multiple wildlife species in Venezuela and evaluated whether available data were sufficient to provide accurate estimates of the magnitude, scope, and detectability of IWU. We compiled records of illegal subsistence hunting and trade from several sources and fitted a random-forest classification model to predict the spatial distribution of IWUs. From 1969 to 2014, 404 species and 8,340,921 specimens were involved in IWU, for a mean extraction rate of 185,354 individuals/year. Birds were the most speciose group involved (248 spp.), but reptiles had the highest extraction rates (126,414 individuals/year vs. 3,133 individuals/year for birds). Eighty-eight percent of international trade records spatially overlapped with domestic trade, especially in the north and along the coast but also in western inland areas. The distribution of domestic trade was broadly distributed along roads, suggesting that domestic trade does not depend on large markets in cities. Seventeen percent of domestic trade records overlapped with subsistence hunting, but the spatial distribution of this overlap covered a much larger area than between commercial uses. Domestic trade seems to respond to demand from rural more than urban communities. Our approach will be useful for understanding how IWU works at national scales in other parts of the world.

RESUMEN

Illegal trade in hazardous waste and harmful chemicals has caused severe damage on human health and the environment, and brought big challenges to countries to meet their commitments to related multilateral environmental agreements. Synergy-building, like organising law enforcement operations, is critical to address illegal trade in waste and chemicals, and further improve the effectiveness of environmental enforcement. This article discusses how and why law enforcement operations can help countries to implement chemical and waste-related multilateral environmental agreements in a more efficient and effective way. The research explores key barriers and factors for organising law enforcement operations, and recommends methods to improve law enforcement operations to address illegal trade in hazardous waste and harmful chemicals.

RESUMEN

On Madagascar, the illegal and unsustainable exploitation and illegal international trade of Dalbergia (rosewood) precious woods remain a serious conservation problem. Members of this genus are at high risk of extinction as a consequence of logging, mining, and slash and burn agriculture. Morphological identification of these Malagasy species is difficult in the absence of flowers and fruits, especially in the case of cut trees, sawn wood, and finished product. In this study, we use molecular barcoding to identify the Dalbergia species with the intent to contribute to the control of their illegal trade. Thirty-six Dalbergia samples representing 12 Malagasy species of which 11 have high commercial value, were collected to test the efficacy of a region of the plastid genome (rbcL) and a nuclear-transcribed ITS for barcoding. These widely used markers, as well as DNA barcoding gaps, "best match" and "best close match" approaches, and the neighbor-joining method were employed. All samples were amplified and sequenced using the two markers. Using a single locus, the "best match" and "best close match" approaches revealed that ITS has high discriminatory power within the tested Malagasy species. The combination of rbcL + ITS revealed 100% species discrimination. This study confirms that ITS alone and in combination with chloroplast barcode rbcL allow non-ambiguous identification for the 12 species studied. The results contribute to the development of DNA barcoding as a useful tool to identify Malagasy Dalbergia and suggest that the approach developed should be expanded to all 56 potentially exploited species in reference to international CITES requirements and the sustainable management of valuable resources.

RESUMEN

BACKGROUND: Tobacco regulations may increase demand for illegal cigarettes. We use the Experimental Tobacco Marketplace to estimate the impact of banning menthol cigarettes (Experiment 1) and decreasing allowable cigarette filter ventilation levels (Experiment 2). METHODS: Crowdsourced participants were randomized into one of four groups (2×2 factorial design). Experiment 1 included menthol availability (yes/no) by purchasing option (legal only vs illegal available). Experiment 2 included filter-vented cigarettes availability (yes/no) by purchasing option (legal only vs illegal available). Participants were given an individualized budget to purchase tobacco. Percent budget spent was the outcome measure. RESULTS: Experiment 1, with a legal marketplace only, non-menthol cigarette purchasing was lower (p=0.010) and electronic-cigarette purchasing was higher (p=0.016), when cigarettes were banned compared to when they were available. With an illegal marketplace, switching to legal non-menthol cigarettes was less likely (p<0.001) and purchasing illegal menthol cigarettes was higher (p<0.001), when cigarettes were banned compared to when they were available. Experiment 2, with a legal marketplace only, cigarette purchasing was lower (p=0.010), when the participant's filtered vented cigarettes were banned compared to when they were available. With an illegal marketplace, purchasing the legal low-ventilated cigarette option was lower (p<0.001) and significant differences in illegal filter-vented cigarette purchasing were not observed, when their filter-vented cigarettes were banned compared to when they were available legally. CONCLUSIONS: Without an illegal option, both restrictions decreased cigarette purchasing, but the menthol ban increased e-cigarette purchasing. With an illegal option, a menthol ban increased illegal cigarette purchasing, but decreasing filter ventilation did not.

RESUMEN

Introduction: Few studies have examined the sales of stolen account credentials on darkweb markets. In this study, we tested how advertisement characteristics affect the popularity of illicit online advertisements offering account credentials. Unlike previous criminological research, we take a novel approach by assessing the applicability of knowledge on regular consumer behaviours instead of theories explaining offender behaviour. Methods: We scraped 1,565 unique advertisements offering credentials on a darkweb market. We used this panel data set to predict the simultaneous effects of the asking price, endorsement cues and title elements on advertisement popularity by estimating several hybrid panel data models. Results: Most of our findings disconfirm our hypotheses. Asking price did not affect advertisement popularity. Endorsement cues, including vendor reputation and cumulative sales and views, had mixed and negative relationships, respectively, with advertisement popularity. Discussion: Our results might suggest that account credentials are not simply regular products, but high-risk commodities that, paradoxically, become less attractive as they gain popularity. This study highlights the necessity of a deeper understanding of illicit online market dynamics to improve theories on illicit consumer behaviours and assist cybersecurity experts in disrupting criminal business models more effectively. We propose several avenues for future experimental research to gain further insights into these illicit processes.

RESUMEN

Molecular DNA barcoding combined with botanical taxonomy can be used for the identification and conservation of collected Greek orchids used for salep production as well as in the regulation of fair salep trade. A modified CTAB protocol was used for DNA extraction, amplification of barcoding regions (ITS, matK, rbcL, trnH-psbA), and sequencing. Sequencing data were assembled using Bioedit software, and the BLAST algorithm was used on the NCBI database for species identification at the genus level. Molecular barcoding data based on genetic similarity identification was in full coherence with taxonomic classification based on morphological data. The combination of ITS and matK exhibited a greater capacity to identify a species among the Greek salep samples. Out of the 53 samples examined, 52.9% were classified as Dactylorhiza spp. and 33.3% as Anacamptis spp., whereas only 6 samples were identified as Orchis spp. (11.8%). Given that a superior-quality salep beverage comes from tubers of the latter, the number of samples classified as such in northwestern Greece is unexpectedly low. A database of 53 original reference sequences from wild-growing samples of Greek origin was generated, providing a valuable resource for the identification of other salep samples from different regions. The DNA barcoding results unveiled that salep samples from northwestern Greece are related to nine members of four different genera of Orchidaceae. All species are nationally protected and covered by the CITES convention, while many of these orchids are included in the EU Directive 92/43/EEC appendix as "Other Important Species". Thus, expedited coordinated management actions are needed to ensure their survival in the future.

RESUMEN

The illegal trade of animals poses several health issues to the global community, among which are the underestimated risk for spillover infection and the potential for an epizootic in both wildlife and domestic naïve populations. We herein describe the genetic and antigenic characterization of viruses of the specie Carnivore protoparvovirus 1 detected at high prevalence in puppies illegally introduced in North Eastern Italy and compared them with those circulating in wild carnivores from the same area. We found evidence of a wide diversity of canine parvoviruses (CPV-2) belonging to different antigenic types in illegally imported pups. In wildlife, we found a high circulation of feline parvovirus (FPV) in golden jackals and badgers, whereas CPV-2 was observed in one wolf only. Although supporting a possible spillover event, the low representation of wolf samples in the present study prevented us from inferring the origin, prevalence and viral diversity of the viruses circulating in this species. Therefore, we suggest performing more thorough investigations before excluding endemic CPV-2 circulation in this species.

RESUMEN

Despite the efforts of the International Marine Organization (IMO), through the International Convention on the Control of Harmful Antifouling Systems on Ships to ban the use of TBT-based antifouling paints (September 2008), and the Rotterdam Convention (RC) to forbid the trade of tributyltin (TBT), the situation does not seem to have significantly changed since 2014 when TBT-based paints were shown to be still being manufactured in the United States and offered for sale in stores throughout the Caribbean and Central America. In fact, this study shows that seven years later the same situation not only persists, but may have an even more global distribution than previously thought.

RESUMEN

The European eel (Anguilla anguilla) is a catadromous species that inhabits the rivers of the Adriatic watershed in Croatia. It is a critically endangered fish species, according to the IUCN, due to its declining abundance in European rivers caused by overfishing and trafficking and by diseases caused by nematodes, pathogenic bacteria and viruses. An illegal parcel of glass eels was confiscated at the Zagreb Airport and was intended to re-populate Croatian rivers. Barcoding was employed to determine species affiliation, and a thorough health check was carried out. This study reports the evaluation of gross lesions, histological findings, and EVEX virus isolation and identification. Since the confiscated glass eels were of unknown origin and given the serological and genetic similarities of EVA and EVEX, we designed primers and probes for almost whole genome sequencing to elucidate the origin of glass eels based on viral phylogeny. Bayesian phylogeny showed that the isolated strain had the most common ancestor with a Danish isolate and likely evolved from the French isolate of EVEX. These findings are discussed in light of the divergence of recently isolated strains and their possible contribution to the decrease of the abundance of the European eel in European waters.

RESUMEN

Wildlife crime is on a massive scale by whatever metric is used. The illegal trade in wildlife and related products is leading to the decline and extinction of many iconic species from rhino to tigers. Almost all countries are signatures to CITES and therefore should enforce national legislation if alleged infringements of trade of wildlife occur. No country is immune from this illegal trade although countries like Australia have their own specific wildlife crimes. Australia is home to many reptilian, amphibian and avian species that are highly prized, predominantly as pets. Collection of protected species from the wild is illegal in all jurisdictions yet policing remote areas of the outback, where so much of the native endemic fauna and flora lives, is nearly impossible. The illegal international trade in these species is highlighted by two case studies provided in this review. A further case highlights the issues of each of the six states of Australia having separate legislation, which is compounded when wildlife crime can be inter-state crime. Australia is one of the few countries having an institute, based at the Australian Museum, with an accredited wildlife forensic science laboratory and therefore the capability to undertake forensic testing of seized samples. One way to reduce wildlife crime may be by educating those who buy illegally seized products that there is a direct connection between the dead animal from which it came and the devasting effect this purchase has on the environment.

RESUMEN

The illegal wildlife trade (IWT) is a criminal practice bringing several ecological and public health consequences, such as the spreading of zoonotic pathogens and/or the introduction of exotic species of animals into new geographical areas. Here, we discuss potential risks of IWT on the spreading and emergence of zoonotic pathogens.

RESUMEN

International trade of animals may represent a gateway for the spreading of zoonotic pathogens and their vectors. Amongst animals, reptiles are commonly illegally imported worldwide, being Italy in the fifth position of importation of these animals. Thus, the current study analysed the pathogens associated with Hyalomma aegyptium ticks, which were collected from illegally imported tortoises from North Africa to Italy. All tick DNA samples were tested by conventional PCR for the presence of Anaplasma spp., Babesia spp., Borrelia spp., Coxiella burnetti, Ehrlichia spp., Hepatozoon spp., Rickettsia spp. and microfilariae of filarioids. Out of 22% (n=161) of ticks screened, 78.9% (n=127) were males and 21.1% (n=34) females. Among them, three male specimens collected from two different turtles (1.9%; 95% CI; 0.5-5.5) scored positive for Anaplasma spp./Ehrlichia spp., whereas all females were negative. BLAST analysis of the sequences obtained from positive samples revealed 99-99.3% nucleotide identity with the sequence of Ehrlichia ewingii available in GenBank. The finding of E. ewingii in ticks from imported reptiles warrants the need for imposing strict rules in the international trade of reptiles to effectively reduce the introduction of exotic pathogens and their vectors in new geographic areas.

RESUMEN

BACKGROUND: The Orange-fronted Parakeet (Eupsittula canicularis) is the Mexican psittacine that is most captured for the illegal pet trade. However, as for most wildlife exploited by illegal trade, the genetic diversity that is extracted from species and areas of intensive poaching is unknown. In this study, we analyzed the genetic diversity of 80 E. canicularis parakeets confiscated from the illegal trade and estimated the level of extraction of genetic diversity by poaching using the mitochondrial DNA sequences of cytochrome b (Cytb). In addition, we analyzed the genealogical and haplotypic relationships of the poached parakeets and sampled wild populations in Mexico, as a strategy for identifying the places of origin of poached parakeets. RESULTS: Poached parakeets showed high haplotype diversity (Hd = 0.842) and low nucleotide diversity (Pi = 0.00182). Among 22 haplotypes identified, 18 were found exclusively in 37 individuals, while four were detected in the remaining 43 individuals and shared with the wild populations. A rarefaction and extrapolation curve revealed that 240 poached individuals can include up to 47 haplotypes and suggested that the actual haplotype richness of poached parakeets is higher than our analyses indicate. The geographic locations of the four haplotypes shared between poached and wild parakeets ranged from Michoacan to Sinaloa, Mexico. However, the rare haplotypes detected in poached parakeets were derived from a recent genetic expansion of the species that has occurred between the northwest of Michoacan and the coastal region of Colima, Jalisco and southern Nayarit, Mexico. CONCLUSIONS: Poached parakeets showed high genetic diversity, suggesting high extraction of the genetic pool of the species in central Mexico. Rarefaction and extrapolation analyses suggest that the actual haplotype richness in poached parakeets is higher than reflected by our analyses. The poached parakeets belong mainly to a very diverse genetic group of the species, and their most likely origin is between northern Michoacan and southern Nayarit, Mexico. We found no evidence that poachers included individuals from Central American international trafficking with individuals from Mexico in the sample.

RESUMEN

Strigiformes are affected by a substantial decline mainly caused by habitat loss and destruction, poaching, and trapping. Moreover, the increasing trend in bird trade and the growing interest in wild-caught rather than captive-bred birds are expected to encourage illegal trade. The biomolecular investigation represents a valuable tool to track illegal trade and to explore the genetic variability to preserving biodiversity. Microsatellite loci (STRs) are the most used markers to study genetic variability. Despite the availability of species-specific microsatellite loci in Strigiformes, a unique panel permitting the description of the genetic variability across species has not been identified yet. We tested 32 highly polymorphic microsatellite markers to evaluate the reliability of a unique microsatellite panel in different species of Strigiformes and its use for conservation and forensic purposes. We included in the study 84 individuals belonging to 28 parental groups and 11 species of Strigiformes. After screening polymorphic microsatellite loci, the description of genetic variability, and the kinship assessment, we characterized a final panel of 12 microsatellite loci able to identify individuals in 9 Strigiformes species. This STR panel might support the authorities in the forensic investigation for suspected smugglers and false parental claims; moreover, it can be useful to evaluate relatedness among individuals in captive-bred populations and to implement research projects finalized to the description of the genetic variability in wild populations.
