The non-traditional companion animal (NTCA) sector, particularly involving avian species, has significantly expanded in Italy, raising concerns over the spread of infectious diseases. These animals can harbor various pathogens and act as reservoirs, posing risks to native wildlife through legal or illegal trade, escapes, or intentional releases. However, the epidemiology of avian pathogens in NTCAs remains poorly understood and is typically investigated only in symptomatic individuals. In the present study, cloacal and choanal cleft swabs were collected from 319 ornamental and raptor birds across 19 families, pooled and tested for beak and feather disease virus (BFDV), avian polyomavirus (APV-1), psittacid herpesvirus 1 (PsHV-1), and avian metapneumovirus (aMPV). BFDV and APV-1 were detected in 13.79% and 2.19% of birds, respectively, with five co-infections. No cases of PsHV-1 or aMPV were found. Both viruses showed a higher prevalence than in previous Italian and most of international studies, with several non-psittacine species, including birds of prey, testing positive—some for the first time. Mixed-species settings and participation in public exhibitions were proven as significant infection risk factors. The study highlights the growing relevance of BFDV and APV-1 in non-commercial birds and recommends improved biosecurity and preventive screening to reduce disease spread and safeguard animal health.

Background: The illegal trade in wildlife remains a critical threat to biodiversity, prompting the development of international regulatory frameworks such as the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). One of the key challenges in enforcement is the detection of CITES-listed species in highly processed consumer goods. Methods: This study investigates the use of molecular techniques to detect animal DNA in two selected commercially available medicinal products—a balm and a gel—marketed with ingredients suggestive of protected species such as the brown bear (Ursus arctos) and the medicinal leech (Hirudo medicinalis). Results: Although DNA from these target species was not detected, the analysis revealed the presence of genetic material from the American mink (Neovison vison) and domestic pig (Sus scrofa), indicating the undeclared use of animal-derived substances. While limited in scope, these findings suggest potential ethical and transparency concerns, particularly for consumers adhering to vegetarian, vegan, or religious dietary practices. Conclusions: The study illustrates the feasibility of applying DNA-based screening methods in complex, degraded matrices and their potential as supportive tools in consumer product assessment. However, broader studies are necessary before drawing general regulatory or conservation conclusions. Full article

The genus Coturnix, comprising migratory Old World quails, includes Common Quail (Coturnix coturnix) and Japanese Quail (Coturnix japonica), which are nearly indistinguishable morphologically. This similarity poses challenges in species identification, leading to conservation issues such as the illegal trade of wild Common Quail in the name of farmed Japanese Quail. To address this issue, we employed two approaches: (1) mining species-specific short sequence repeats (SSRs) and (2) designing a PCR-restriction fragment length polymorphism (PCR-RFLP) assay targeting the COX1 gene to distinguish these species. While SSR markers proved unreliable, the PCR-RFLP assay successfully distinguished between Common Quail and Japanese Quail, leveraging the unique BsaBI restriction site in the Common Quail COX1 gene. This method demonstrated high specificity and reproducibility, offering a robust tool for forensic and conservation applications. Our findings provide a reliable, efficient, and accessible technique for wildlife managers and researchers to regulate the illegal trade of Coturnix quails and support conservation efforts.

Recreational hunting is a highly regulated activity, in part because it can give rise to a variety of deleterious social, environmental, and economic harms. It provides an interesting area for those interested in community safety because of the way in which both formal (e.g., enforcement officers, proscribed areas and times for hunting, licensing, etc.) and informal (e.g., community awareness and education, conservation) methods of crime prevention are applied. And yet, the criminological literature on effective regulation is not only limited but diverse in terms of scope, types of behavior considered (e.g., poaching, wildlife trading, recreation, etc.), and the context that is considered (e.g., geographical, cultural, etc.). In this paper, we present how a crime prevention and compliance response can be used to understand the nature of the issue and the individual and socio-political processes that result in non-compliance with hunting regulations. We present an overview of the status of recreational hunting in an Australian jurisdiction and locate the regulatory issues that arise within the research literature that explores the various motivations that are known to drive illegal hunting. These are then considered in relation to how community-oriented and non-coercive measures might be employed to improve prevent criminal behavior at the primary, secondary, and tertiary levels.

The illegal trade in leopard and lion parts is a major threat to felid conservation across Africa, especially in under-researched areas like francophone West Africa. Between April and June 2024, we conducted surveys in 16 cities and 46 markets in Côte d’Ivoire, interviewing 39 sellers and 14 users of felid products. We found leopard and lion parts in 42.7% and 25% of stalls, respectively. The illegal trade is driven by the demand for felid products for traditional purposes, with both species holding strong symbolic values. Products were often trafficked through informal networks and sourced from Sahelian neighboring countries like Mali and Burkina Faso. We identified some key trade routes across West Africa and beyond. Without effective control measures, this illegal trade could accelerate the decline of West Africa’s remaining large felid populations. We recommend establishing a regional database of confiscated felid parts for genetic tracing and developing standardized questionnaires for use during traffickers’ arrests to gain further insights into their operations. Additionally, targeted behavioral change campaigns should be implemented to address corruption, increase enforcement agencies’ interest and capacity, and shift the practices of traditional practitioners toward sustainable alternatives. Training law enforcement officers, raising awareness among key communities, and increasing cross-border collaboration and controls are critical to providing a more comprehensive understanding of the trade dynamics in the region.

Conservation strategies that use sustainable use of natural resources through green-labelled markets generally do not recognize the legal sale of wild meat as appropriate due to potential overexploitation and zoonotic disease risks. Wildlife hunting is important to the livelihoods of rural communities living in tropical forests for protein and income. Wildlife management plans in the Peruvian Amazon permit hunting of wild meat species for subsistence and sale at sustainable levels, that include peccaries, deer, and large rodents. These species have fast reproduction making them less vulnerable to overhunting than other species. This study assessed the sustainability of a wildlife management plan. Populations of species were estimated using camera traps and distance transect surveys, and sustainability analysis used hunting pressure from community hunting registers. Interviews were conducted to understand hunters, perceptions of the management plan. Long-term time-series showed increases in collared peccary (3.0 individual/km² to 5.41 individual/km²) and white-lipped peccary (3.50 individual/km² to 7.00 individual/km²) populations and short-term time series showed a decline in paca populations from 8.5 individual/km² to 3.01 individual/km². The unified harvest analysis showed permitted species populations were greater than 60% of their carrying capacities and hunted at less than 40% of their production, which shows sustainable hunting. The wildlife management plan achieved its general objective of sustainable hunting and improving livelihoods. The broader question is whether sustainable wildlife use plans that allow Amazonian communities to sell limited amounts of wild meat can be a way to change illegal wild meat trade to a legal, green labelled trade with added value.

In recent decades, illegal wildlife trade has become a global problem that threatens the conservation of many species. To promote sustainable animal trade, conservation plans must be developed and implemented locally. However, illegal trade in protected aquatic wildlife still occurs in many places. To understand the current situation of illegal sales, we conducted a sampling survey on eight sites in Xiamen for 5 consecutive years. The results show that illegal sales behavior is widespread, but there are changes. Notably, the proportion of stores with illegal sales fell from 17.7% in 2018 to 10.8% in 2022. We observed 24 species, 12 of which are listed in CITES. Among them, 15 species were recorded in annual surveys, accounting for 62.5% of the total species surveyed. Among the 24 species investigated, there were 8 living species. From 2018 to 2022, the number of food stalls selling protected species dropped the most, from 22.7% to 0%. Followed by dry goods stores, the number of stores selling protected species dropped from 24% to 8.3%. However, the number of craft shops selling protected species increased by 14.8%. It put forward protection suggestions such as focusing on cracking down on illegal sales and strengthening consumer publicity and education. Full article

Rapid and effective methods for tracing the geographic origin of wildlife samples are essential for tackling the illegal wildlife trade. Traditional morphological categorization methods are often inadequate as relying on the mitochondrial COXI barcode is insufficient for determining geographic populations. To address these limitations, we developed a bioinformatics-based pipeline for the rapid identification of traceable nuclear genome loci. This pipeline has been applied to the whole-genome sequence (WGS) data of China’s flagship species, the snub-nosed monkey (Rhinopithecus spp.). These species are known for sex-biased dispersal and hybrid speciation, which complicates genealogy tracing. Using phylogenetic principles, we employed the Robinson and Foulds (RF) distance and scanned over 1,850,726 population-specific loci, identifying five pairs that can trace genealogy origins rapidly and cost-effectively using PCR. Additionally, we found that relying only on mitochondrial genetic information is insufficient for rapid and accurate traceability to subspecies-level geographic populations. Our pipeline efficiently identifies loci and traces the geographic origin of snub-nosed monkey individuals, providing a valuable tool for species preservation and combating the wildlife trade. This approach can be extended to other species, aiding in the conservation of endangered wildlife and tracing criminal evidence. Full article

With the online wildlife trade and the demand for viral videos increasing, the trade in primates on TikTok is becoming more prevalent. Despite wildlife trading being banned on most social media platforms, the trade in primates persists. TikTok’s policies ban the sale of live animals, and specific terms related to wildlife trading are banned; however, these search-term bans are easy to get around, and sellers are still prolific on the site. This study documented primates for sale on TikTok using the search term “for sale monkey” over a four-month period (from mid-July to mid-November 2023) with the aim of determining how widespread primate trade is on TikTok, the legality of advertisements, and which countries advertise the most primates for sale. In total, 43 individual advertisements were identified, spanning six different genera of primates and five different countries. Spider monkeys, rhesus macaques, and common marmosets were found to be the most commonly advertised species on TikTok. All the spider monkeys were advertised from the USA, while the majority of the marmosets were advertised from the UK, and all of the rhesus macaques were advertised from Pakistan. The USA was the only country identified in this study that advertised a range of species, and the only species found in this study that was not advertised in the USA was the mona monkey. In total, 44% of all species recorded were classified as either Endangered or Critically Endangered, and it was found that Endangered species were more frequently sold illegally than non-Endangered species. The findings of this study underline a need for stricter primate legislation and wildlife law enforcement, especially if the UN’s sustainable development goals are to be achieved by 2030. They also show a need for TikTok to broaden their restrictions on wildlife trading on their app. Full article

The Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) aims to prevent the overexploitation of species by controlling their trade. However, there is currently no international regulatory framework to protect the trade of non-CITES species. We examined the LEMIS database, online trade, and scientific literature with the aim of identifying and compiling a list of South African native species traded as pets and wildlife products. We found that there are 223 non-CITES species traded as wildlife products and 95 species traded as pets. Mammals and birds were the most traded taxa for wildlife products, while reptiles and amphibians were mostly traded as pets. At the least, species traded as wildlife products and pets are currently not facing extinction, as most are categorized as Least Concern. However, some endemic species have an unknown population size, with Sclerophrys pantherina and Neamblysomus gunningi being Endangered. The international pet trade involves 10 countries, with the USA, the Czech Republic, and the UK being the largest importers. The trade of species as wildlife products involves 20 countries, with the USA being the major importer. This study emphasizes the necessity of strict regulations and international cooperation to control the wildlife trade effectively. Full article

Wildlife trade, both legal and illegal, is increasingly recognized as a key factor in the rise of emerging viral infectious diseases, and this is especially apparent in Asia, where large numbers of wildlife are openly offered for sale in bird markets. We here focus on the risk of Psittacosis becoming a zoonotic disease in the wildlife markets of Java and Bali, Indonesia. Psittacosis is particularly prevalent in parrots (hence the name), and the trade in parrots was instrumental in the Great Parrot Fever Pandemic in 1929/1930. Between 2014 and 2023, we conducted 176 surveys of 14 bird markets, during which we recorded 4446 largely wild-caught parrots for sale. On average, each market had nine genera on offer, and the diversity of genera increased with the increasing presence of parrots (up to 16 genera). For most of the bird markets during each survey, parrots from different genera and originating from different parts of the world, were offered for sale alongside each other. Genera offered for sale together did not cluster into natural (geographic) groups. We found no temporal difference in the sale of parrots. We conclude that the omnipresence of wild-caught parrots from various geographic regions in large numbers within the same bird markets increases the risk that psittacosis is present and that this poses a real risk for the zoonotic spread of avian chlamydiosis to humans.

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. Full article

An animal’s ability to navigate its home range in search of essential resources is a key aspect of its ecology. To reach these resources, animals employ varying navigational processes depending on their exocentric or egocentric view of their environment. The goal of this study was to determine if the Javan slow loris (Nycticebus javanicus), a nocturnal arboreal primate found in southeast Asia, uses some form of cognitive map and spatial memory while navigating their environment. Using behavioural and GPS data of six males and seven females collected at the Little Fireface Project field station based in West Java, Indonesia, we measured their frequency of revisiting important feeding trees, route overlap, and points where individuals significantly changed directions. We found that all individuals predominantly used four tree species while feeding and foraging. The lorises also displayed a high level of route overlap, leading us to conclude that they likely utilize a route-based cognitive map where certain landmarks are integral to their nightly movement. Few studies have specifically focused on strepsirrhine spatial cognition in the wild; here, we show the navigational mechanism used by the Javan slow loris to reach distant/out-of-sight resources. The evident reliance on spatial cognition in a strepsirrhine species suggest that it could be an important selective pressure for primates at the earliest stages of primate cognitive evolution. In addition to the importance of spatial memory in theoretical discourse, understanding slow loris movement has practical applications to conservation, particularly regarding the numerous translocations undertaken by individuals rescued from the illegal wildlife trade. We discuss the importance of considering soft release training and monitoring in such releases. Full article

Overexploitation has driven catastrophic declines in most turtle species in Asia. Many turtles are seized annually by law enforcement officers; unfortunately, seized turtles often lack associated information on their provenance. There is also taxonomic confusion regarding the clear delineation of turtle species and subspecies in Asia. This lack of provenance data and taxonomic uncertainty is problematic as it may preclude release, make appropriate release sites hard to select, or result in genetic pollution when animals are released. In this study, we amassed and analyzed the largest number of genetic samples of the critically endangered big-headed turtle (Platysternon megacephalum) to date. Our phylogenetic and network results based on nearly 500 sequences of a mitochondrial ND4 fragment corroborate the earlier hypothesis that only two of the three currently recognized subspecies have strong molecular support and that there is greater genetic structuring within one subspecies than has been previously reported. The vast majority of P. megacephalum confiscated from the trade in Vietnam belong to Subclade 3 of P. m. peguense, and this subclade is the most broadly distributed taxon of the big-headed turtle in Vietnam based on samples with known localities. Nonetheless, for the other two subclades, all their samples originate from the trade and could not be assigned to any geographic provenance because of the lack of wild-caught samples. In addition, our results reveal two trade centers of the species, Quang Ninh Province on the border between China and Vietnam and Kon Tum Province in the Central Highlands. However, smaller animal seizures occur across the range of the species in Vietnam. While the data presented here have facilitated the selection of appropriate release sites for confiscated P. megacephalum, the significant costs of genetic screening and the shortage of samples from wild animals with good localities hinder the rewilding efforts, especially for conservation practitioners working in countries where conservation activities are not well funded and research on poorly studied species is still limited. Nevertheless, we urge that wildlife translocations include robust pre-translocation genetic screening to ensure that all individual animals are reintroduced at appropriate sites. Full article

Illegal, unreported, and unregulated fishing, including that of sharks, poses a significant threat to marine ecosystems and individual species. I use data from the media, tourists, and artisan fishermen to gain insight into the trade in the world’s largest fish, the whale shark (Rhincodon typus). I focus on the Indonesian island of Java where, along its south coast, whale sharks are landed and butchered on the beach in view of hundreds of people and local media. Whale sharks are typically caught in fishing nets and dragged alongside boats to the shallows, where they are butchered. The meat and oil (valued at ~USD 2000 per shark) are sold and distributed within the community. I document 58 landings of mainly immature whale sharks (2002–2022). Artisanal fishermen see the landing of whale sharks as a fortuitous event, but the species is protected, and Indonesia is a signatory to various international agreements that preclude the fishing of whale sharks. It is imperative for the conservation of whale sharks that the various parties in Indonesia adhere better to their own rules and regulations protecting this species. Full article
