“…Presently, Shanghai, Anhui, Hubei, Henan, and Jiangsu provinces face a high risk of invasion, while Jiangxi, Zhejiang, and Fujian provinces have a relatively low risk. Existing research reports indicate that only the Hong Kong region in China has recorded dense wild sightings of C. serpentina (Sung et al, 2021). However, Hong Kong does not fall within the suitable habitat range according to our findings.…”

“…The dispersal capacity and pathway of invasive species significantly affect the scope and speed of invasion (Hulme, 2009). As C. serpentina has weak dispersal abilities (Obbard and Brooks, 1981), releasing them into the wild is likely the primary way they spread in China (Liu et al, 2021;Sung et al, 2021). Therefore, it is crucial to consider local customs and habits when investigating their distribution.…”

“…C. serpentina is frequently discovered in the natural habitats of China and has been featured in various online news outlets (Liu et al, 2021). In the region of Hong Kong, C. serpentina has also been witnessed on no less than 10 occasions (Sung et al, 2021). Therefore, we hold the belief that China is currently confronted with a significant risk of C. serpentina invasion.…”

“…Globally, non-native freshwater turtles have been intentionally or unintentionally introduced into various habitats (Sung et al, 2021), causing damage to local biodiversity and ecosystems through competition (Dıáz-Paniagua et al, 2011), hybridization (Ueno et al, 2021), and the spread of parasites (Mendoza-Roldan et al, 2020) and diseases (Bosch et al, 2015). To prevent the further spread of invasive alien species (IAS), employing species distribution models (SDMs) to analyze the current and future ranges of IAS can provide a scientific basis for decisionmaking (Bertolino et al, 2020).…”

Chelydra serpentina, a species introduced to China for aquaculture purposes, is commonly found in its natural habitats within the country. The invasion of C. serpentina poses potential threats to both the biodiversity of China and human health. The potential distribution of C. serpentina has been simulated using the species distribution model – MaxEnt, incorporating global distribution data, climate, and land cover variables. Our simulations encompasses both current conditions and four future climate change scenarios. Currently, the potential distribution is concentrated in central, eastern, and southeastern regions of China, with the central and eastern regions facing the highest risk of invasion. Under future climate change scenarios, the distribution area may expand by 30–90%, and multiple provinces will face a more severe threat of invasion. This study presents the inaugural simulation of the potential invasion range of C. serpentina under current climatic conditions. Moreover, it reveals that climate change is likely to contribute to the expansion of its invasive range, thus furnishing a reference foundation for scientific prevention and control measures. We propose integrating citizen science and eDNA technologies into species monitoring to enhance the efficiency of detecting invasive species. This research has filled the gap in the research on the invasive distribution range of C. serpentina in China and globally, while also providing novel perspectives on the invasion control of this species.

“…Statistics reveal a doubling of non-traditional pet imports (excluding common companion animals) between 2012 and 2017, with the top five reptile species consistently representing 55–70% of this increasing demand [ 17 ]. This growing interest, however, is overshadowed by concerns around the release or escape of non-native reptile species into the local environment [ 18 , 19 , 20 ], further highlighting the need for responsible pet ownership and management strategies.…”

We investigated the evolving landscape of reptile pet ownership in Hong Kong. Employing a quantitative approach, a self-administered survey was distributed and over 200 reptile pet owners residing in Hong Kong responded. The survey instrument captured demographic data on pet ownership history, species preferences, husbandry practices, and veterinary care utilization. The findings revealed a strong interest in pet reptiles, with lizards being particularly popular (67%) among new owners. Turtles remain common (35%), likely due to cultural factors and perceived ease of care. However, a gap was noted between the awareness and the implementation of proper husbandry practices, with 51% of respondents expressing concerns about enrichment and 21% uncertain about appropriate enclosure size. Veterinary care utilization also showed a disconnect, with 50% of the respondents reporting no regular check-ups were performed, despite acknowledging its importance. Reptile behavior served as a well-being indicator. Over 90% of the respondents observed normal behaviors like locomotion and breathing. Interestingly, a positive correlation emerged between reptile behavior scores and duration of ownership (r = 0.200, p < 0.01), suggesting improved well-being for reptiles that were in long-term care. These findings emphasize the need for educational initiatives promoting responsible pet ownership practices and fostering collaboration between reptile owners, veterinarians, and animal welfare organizations. By addressing these knowledge gaps and promoting a collaborative approach, our results aim to contribute to enhanced reptile welfare in the context of Hong Kong’s evolving pet ownership trends.
