While urban areas may not seem conducive to human-wildlife interactions (HWI), rapid land use transformations can result in frequent encounters with wildlife in the context of changing habitats, as well as encounters with species that thrive in urban settings. In Asia, the processes of rapid land-use change can bring into sharp relief the juxtaposi...

Free-roaming dog populations ensue from irresponsible dog ownership and abandonment. The Society for the Prevention of Cruelty to Animals (SPCA) in Hong Kong SAR offers practical solutions to control dog population growth by providing a range of different birth control programs. We present the first results of a trial Trap Neuter Return (TNR) progr...

Hunted wildlife can often be used to answer questions about wild individuals. Sex ratios of hunted individuals can be important for understanding changes in population demographics and viability. Here we determined the sex ratio of the illegally hunted helmeted hornbill Rhinoplax vigil, a critically endangered species from Southeast Asia, to examin...

Wildlife trade is a multi-billion-dollar sector that impacts a wide range of species, and thus is of significant research and conservation interest. Wildlife trade has also become a prominent topic in the public-facing media, where coverage has intensified following the outbreak of the global COVID-19 pandemic due to the potential connection betwee...

Experiments are widely used to investigate the behaviour and cognition of animals. While the automation of experiments to avoid potential experimenter bias is sometimes possible, not all experiments can be conducted without human presence. This is particularly true for large animals in captivity, which are often managed by professional handlers. Fo...

Urban ecology and tropical biology have both developed rapidly in recent decades and matured into important interdisciplinary fields, with significant implications for biodiversity and human communities globally. However, urban ecosystems within the tropics remain understudied and poorly characterized despite these systems representing major hotspo...

Sleep is associated with many costs, but is also important to survival, with a lack of sleep impairing cognitive function and increasing mortality. Sleeping in groups could alleviate sleep‐associated costs, or could introduce new costs if social sleeping disrupts sleep. Working with the Jamaican fruit bat ( Artibeus jamaicensis) , we aimed to: (1)...

Captive and domestic animals are often required to engage in physical activity initiated or organised by humans, which may impact their body temperature, with consequences for their health and welfare. This is a particular concern for animals such as elephants that face thermoregulatory challenges because of their body size and physiology. Using in...

Nature has the potential to provide wide-ranging economic contributions to society – from ecosystem services to providing income to communities via fair trade of resources. Unsustainable trade in wildlife, however, threatens biodiversity and its ability to support communities and a functioning planet. It is therefore important to have clear systems...
