The number of puppies imported to the United Kingdom (UK) from the European Union (EU) is increasing, as are concerns about the legality, welfare and potential disease risks associated with their trade. This study aimed to use an online survey to collect questionnaire data from UK residents about their awareness and knowledge of EU Pet Passports, illegal puppy importation, and dog-borne exotic diseases and the risks they might pose to UK-resident dogs and people. Valid responses were collected from n = 7184 UK residents, mainly current dog owners. We identified substantial knowledge gaps relating to EU Pet Passports, how puppies might be moved across Europe, and the legal age of importation. Awareness of exotic diseases was poor; knowledge about the risks they posed was even poorer, particularly in relation to dog–human transmission. With some respondents not even being confident that they had heard of rabies, there is substantial work to do to ensure that the UK canine and human populations remain safe in the face of significant welfare and exotic disease threats. These knowledge deficits may facilitate the burgeoning illegal trade in puppies across the EU. Legal change may be required to prevent consumers from unintentionally supporting poor welfare sources of puppies. Full article

In this study, we evaluated genetic parameters and progress in growth traits and heat tolerance across four Thai native synthetic chicken lines—Kaimook e-san, Soi Pet, Soi Nin, and Kaen Thong—over seven generations. Growth traits, including body weight (BW), average daily gain (ADG), and breast circumference (BrC), were recorded and analyzed from hatching to 14 weeks of age, with heat stress assessed based on the temperature–humidity index (THI). Genetic parameters were estimated using a multi-trait animal model incorporating THI thresholds. Significant differences in growth traits were observed among the lines (p < 0.05). Kaimook e-san consistently exhibited superior performance, with males outperforming females, while Kaen Thong showed the lowest performance across all traits. Heritability estimates declined with age, with higher values observed in early growth stages, indicating stronger genetic influence during early development. Strong negative genetic correlations between heat tolerance and growth traits were observed in Kaimook e-san, while Kaen Thong showed weaker correlations, suggesting greater potential for simultaneous improvement in growth and heat tolerance. All lines demonstrated genetic progress in growth traits across generations, with Kaimook e-san achieving the highest gains, although these were accompanied by a decline in heat tolerance. The findings highlight the trade-offs between growth and thermal resilience and underscore the importance of multi-trait selection strategies for sustainable poultry breeding in tropical environments.

The exotic pet trade is a major driver of alien species invasions. Improper introductions or a lack of management can result in severe ecological consequences. Therefore, accurate identification of exotic pets is essential for the prevention and early warning of species invasions. This paper proposes a novel recognition method for fine-grained images of small-scale exotic pet snakes in complex backgrounds based on an improved SimCLR framework. A hierarchical window attention mechanism is introduced into the encoder network to enhance feature extraction. In the loss function, a supervised contrastive mechanism is introduced to exclude false negative samples using label information, which helps reduce representation noise and enhance training stability. The training strategy incorporates random erasing and random grayscale data augmentation techniques to improve performance further. The projection head is constructed using a two-layer multilayer perceptron (MLP), and the cosine annealing schedule combined with the AdamW optimizer is adopted for learning rate adjustment. Experimental results on a self-constructed dataset demonstrate that the proposed model achieves a recognition accuracy of 97.5%, outperforming existing baseline models. This study fills a gap in exotic pet snake classification and provides a practical tool for species invasion prevention and early detection. Full article

Positron emission tomography (PET) is an imaging modality for non-invasive visualization and quantification of molecular pathways in human diseases, with applications spanning clinical practice and biomedical research. Recent advances in PET system technology target ultra-high spatial resolution (<2 mm) to enhance diagnostic precision for early-stage disease detection and longitudinal monitoring. A key strategy involves organ-specific, or loco-regional, scanner configurations that optimize photon detection efficiency (PDE) while balancing the trade-off between spatial resolution and image signal-to-noise ratio (SNR). This study reviews innovations driving the development of next-generation clinical PET systems, including the following: (1) novel geometries tailored for anatomical regions such as the head/neck and breast, (2) high-performance detector materials and readout electronics, and (3) advanced image reconstruction algorithms. This paper emphasizes progress toward achieving ≤2 mm isotropic spatial resolution in clinical PET systems, and in particular focuses on describing a 1 mm³ resolution system dedicated to head-and-neck or breast cancer imaging that was developed in our laboratory.

The commercial wildlife trade involves billions of animals each year, consumed for various purposes, including food, fashion, entertainment, traditional medicine, and pets. The experiences of the animals involved vary widely, with negative welfare states being commonplace. To highlight the broad scope of animal welfare impacts across the commercial wildlife trade, we present ten case studies featuring a range of species traded globally for different purposes: (1) Ball pythons captured and farmed to serve as pets; (2) Zebrafish captive bred to serve as pets; (3) African Grey Parrots taken from the wild for the pet industry; (4) Sharks de-finned for traditional medicine; (5) Pangolins hunted for traditional medicine; (6) Crickets farmed for food and feed; (7) Frogs wild-caught for the frog-leg trade; (8) Crocodilians killed for their skins; (9) Lions farmed and killed for tourism; and (10) Elephants held captive for tourism. The case studies demonstrate that wild animals commercially traded can suffer from negative welfare states ranging from chronic stress and depression to frustration and extreme hunger. The individuals involved range from hundreds to billions, and their suffering can last a lifetime. Given the welfare issues identified and the growing recognition and scientific evidence for animal sentience, we propose reducing and redirecting consumer demand for these consumptive wildlife practices that negatively impact animals.

Understanding owners’ realities and perceptions may be crucial to helping veterinarians be more effective in their daily work. Noticing the lack of publications in this area, specifically on exotic pets, prompted us to gather insights into non-traditional companion animal owners. A survey was conducted, resulting in 541 respondents from Portugal and Spain. The results were characterised based on demographics, data on trade and antibiotic and parasiticide use, and the relations between these variables. We found that there is still a considerable part of unregistered animals and that, overall, owners acknowledged antimicrobial resistance and inadequate use of parasiticides. Hopefully, these data will help veterinarians in tackling these problems and enhance owners’ education and compliance. Full article

Leishmaniasis is classified as a neglected tropical disease (NTD), caused by protozoan parasites of the genus Leishmania, which are transmitted to humans and other animals through the bite of infected female phlebotomine sandflies. There are three forms of the disease: cutaneous leishmaniasis (CL) manifested by ulcers and scars; systemic or visceral leishmaniasis (VL), which can lead to life-threatening complications if left untreated; and mucocutaneous leishmaniasis (MCL), which can destroy the mucous membranes of the nose, mouth and throat. Human leishmaniasis is endemic in many countries across Africa, Asia, Southern Europe, the Middle East, and Central and South America. The interconnection of environmental, animal and human health underlies the spread of the Leishmania parasite. Environmental disruptions, such as climate change, deforestation or urbanisation, but also globalisation and migration, significantly affect the distribution and abundance of sand fly vectors and reservoir hosts. Climate change alters the breeding patterns of sandflies and expands their geographic range; deforestation and misuse of large areas disrupt ecosystems, leading to increased human-vector contact; and urbanisation increases the potential for contact between parties, particularly in densely populated areas. Migration of humans and animals, either through natural migration or, for example, the pet trade and breeding, can facilitate the spread of Leishmania parasites. In addition, socio-economic factors, including poverty and lack of access to healthcare, increase the burden of leishmaniasis in vulnerable populations. Due to this multitude of reasons, the geographic distribution of sandflies has expanded to higher latitudes and altitudes in recent years, with a consequent increase in disease burden. Indeed, despite ongoing challenges in the surveillance systems, data from the last available year have shown an increase in many cases in both humans and dogs. This perspective explores the interconnected factors influencing the spread of leishmaniasis worldwide and the epidemiology of the disease. In addition, it illustrates the importance of integrated strategies in a One Health approach: surveillance, prevention and control of vectors, animals and humans. Full article

Parrots are popular with pet consumers and are one of the most traded groups of live birds around the world. China has been considered as an important country in bird trades, but we know little about China’s import and export of parrots. Using the latest data available from the CITES Trade Database, we analyzed China’s import and export of CITES-listed live parrots from 1981–2022 to better understand the patterns and dynamics of these trades. China imported 155,339 parrots of 173 species and exported 608,987 parrots of 42 species during the study period with an annual average of about 18,500 individuals, accounting for c. 5% of the global average number. The most imported parrots to China were Grey Parrot (Psittacus erithacus) and Monk Parakeet (Myiopsitta monachus), while the most exported ones were Fisher’s Lovebirds (Agapornis fischeri), Rosy-faced Lovebirds (Agapornis roseicollis), and Yellow-collared Lovebird (Agapornis personatus). Since the early 21st century, China’s imports of parrots gradually increased, but exports decreased more pronouncedly, making China’s international parrot trade volume declining in the past 20 years. China’s international parrot trade routes also changed over time, with the destination of parrot exports shifting from Europe to Africa and the Arabian region, while more parrots being gradually imported from countries in South America and Africa. The vast majority of parrots exported from China were captive-bred non-native species like Fisher’s Lovebirds, while a substantial proportion of imported parrots were wild-sourced and the proportion has been increasing in the last decade. The fact that China exported much more parrots than imported suggests existence of large-scale parrot farming and domestic parrot trade in China. Attention needs to be paid to monitoring China’s import of increasing proportion of wild-sourced parrots from South America countries and its potential impacts on their wild populations. Close monitoring of and more studies on domestic and illegal parrot trade are essential to fully understand the role China plays in the international trade of parrots. Full article

The global pet trade is a thriving multibillion-dollar industry, involving the international exchange of various species and regulated by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). South Africa plays a significant role as both an importer and exporter within this market. By analysing over 13 million records from the CITES database, spanning from 1975 to 2023, we aimed to access South Africa’s role in the international pet trade and to analyse trade volume and trends over time. Our findings indicate that alien species dominate exports, particularly birds and mammals, while native species are traded in lower volume, involving only a few species. The top 10 traded species for birds and mammals belong to the genera Agapornis and Callithrix, while 80% of reptile exports were native, with Stigmochelys pardalis being the most exported species. Bird and mammal exports are primarily composed of captive-bred individuals, whereas both captive-bred and wild-sourced individuals contribute to reptile exports. Approximately 100 countries import various species from South Africa, with Asia and Europe as major importers of birds. The extensive exportation of South Africa’s native species, particularly reptiles, raises significant conservation concerns regarding the potential impact on local biodiversity. 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

Ecosystems offer natural resources and habitats for humans, serving as the foundation for human social development. Taking the Tianshan Mountains as the study area, this study investigated the changing trends, hot spots, and driving factors of water yield (WY), soil conservation (SC), carbon storage (CS), and habitat quality (HQ), in the Tianshan region, from 1990 to 2020. To determine the trade-offs and synergies between the ESs, we employed the Spearman correlation coefficient, geographically weighted regression, the self-organizing map (SOM), and other methods. Five main results were obtained. (1) There were similar spatial distribution patterns for WY, HQ, CS, and SC, with high-value areas mainly concentrated in grassland zones, forest zones, river valleys, and the intermountain basins of the mountain range, while regions with low value were clustered in desert zones and snow/ice zones. (2) According to the hotspot analysis, areas with relatively strong ES provisioning for WY, HQ, CS, and SC, were primarily concentrated in the BoroHoro Ula Mountains and Yilianhabierga Mountains. In contrast, areas with relatively weak ES provisioning were mainly located in the Turpan Basin. (3) Precipitation was the primary explanatory factor for WY. Soil type, potential evapotranspiration (PET), and the normalized difference vegetation index (NDVI) were the primary explanatory factors for HQ. Soil type and NDVI were the primary explanatory factors for CS. PET was the primary explanatory factor for SC. (4) There were synergistic relationships between the WY, HQ, CS, and SC, with the strongest synergies found between CS–HQ, WY–HQ, and WY–SC. (5) Six ES bundles were identified through the SOM method, with their composition varying at different spatial scales, indicating the need for different ES management priorities in different regions. Our analysis of ESs, from various perspectives, offers insights to aid sustainable ecosystem management and conservation efforts in the Tianshan region and other major economic areas worldwide.

Wildlife trafficking and human–wildlife conflict are major causes of species decline. The illegal nature of wildlife trafficking makes it hard, and sometimes dangerous, to study. ‘Mansión Mascota’ is a veterinary clinic in Guayaquil, Ecuador, which, through agreement with the Ecuadorian Ministry of the Environment, receives confiscated wildlife for treatment. Mansión Mascota also receives injured and abandoned wildlife brought in by the authorities and the public. Between January 2018 and September 2022, the clinic received 3212 wild animals from ≥171 taxa, including mammals, birds, reptiles, and amphibians. Through the classification of records based on reported use, native distribution, and evidence of capture/pet keeping, we were able to classify 1127 animals of 68 species as subject to wildlife trafficking. Turtles were the most abundant group (69%). The majority of turtles (91%) and primates (80%) were of Amazonian origin, whereas 90% of psittacines and 97% of carnivores had potential coastal origins. Threatened and conservation-dependent species were common in the traffic. Furthermore, ≥955 animals of 106 species were brought to the clinic due to anthropogenic wildlife conflict. Trafficking, combined with the high number of injured animals, highlights the synergistic threats facing wildlife in Ecuador. Full article

Exotic animals traded and kept as pets can transmit a variety of diseases to humans and other animals, and vice versa. Therefore, it is essential for pet owners, particularly vulnerable groups, to be informed about associated risks. Veterinarians play a crucial role in informing pet owners about health risks associated with zoonotic pathogens and antimicrobial resistance (AMR) and should, therefore, have good communication skills to effectively transfer information to pet owners. Thus, exotic pet owners in Germany were surveyed on animal husbandry, veterinary consultation and risk communication. To evaluate the perception of communication, a self-developed questionnaire was used to derive a communication score. The perception of veterinarian communication received a high average score showing a high level of satisfaction. The duration of the veterinarian–client relationship was associated with better communication perception, and the frequency of communication on zoonoses and AMR was associated with the presence of a permanent veterinarian. However, the results indicated that the frequency of disseminated information on zoonoses and/or AMR from veterinarians was lower than desired by the pet owners. Therefore, more educational material on zoonoses and AMR should be made available, and the awareness concerning risk communication should be increased by further education and training at universities.

The global trade of non-native pet birds has increased in recent decades, and this has accelerated the introduction of invasive birds in the wild. This study employed ensemble species distribution modelling (eSDM) to assess potential habitat suitability and environmental predictor variables influencing the potential distribution of non-native pet bird species reported lost and sighted in South Africa. We used data and information on lost and found pet birds from previous studies to establish and describe scenarios of how pet birds may transition from captivity to the wild. Our study revealed that models fitted and performed well in predicting the suitability for African grey (Psittacus erithacus), Budgerigar (Melopsittacus undulatus), Cockatiel (Nymphicus hollandicus), Green-cheeked conure (Pyrrhura molinae), Monk parakeet (Myiopsitta monachus), and Rose-ringed parakeet (Psittacula krameri), with the mean weighted AUC and TSS values greater than 0.765. The predicted habitat suitability differed among species, with the suitability threshold indicating that between 61% and 87% of areas were predicted as suitable. Species with greater suitability included the African grey, Cockatiel, and Rose-ringed parakeet, which demonstrated significant overlap between their habitat suitability and reported lost cases. Human footprint, bioclimatic variables, and vegetation indices largely influenced predictive habitat suitability. The pathway scenario showed the key mechanisms driving the transition of pet birds from captivity to the wild, including the role of pet owners, animal rescues, adoption practices, and environmental suitability. Our study found that urban landscapes, which are heavily populated, are at high risk of potential invasion by pet birds. Thus, implementing a thorough surveillance survey is crucial for monitoring and evaluating the establishment potential of pet species not yet reported in the wild. Full article
