The study suggests that common ground can be found in caring for animals, and collaborative solutions such as involving cat care...
The Wildlife Conservation Society has released a list of Asian species at the conservation crossroads, calling for governments to take immediate action. These species face daunting challenges from habitat loss, hunting, and trade, but WCS believes they can be saved using the 'three R's approach: recognition, responsibility, and recovery.
The Wildlife Conservation Society and partners are calling on governments to take urgent action to save shark and ray species from over-fishing for international trade. Currently, only a handful of species are listed under CITES, but numerous others qualify for protection.
In Chitwan National Park, Nepal, tigers have shifted their nocturnal activity to coexist with people, indicating a potential middle ground for human and tiger survival. The study suggests that conservation efforts can consider both nature and humans, paving the way for sustainable solutions.

A study finds that citizens do a better job of picking threatened species than the US Fish and Wildlife Service. Citizen-initiated listings are more likely to pose conflicts with development, but those species are also significantly more threatened on average.
A new study reveals that protected areas are crucial habitats for animal species to colonize and thrive as they migrate towards the poles. The research analyzed millions of records from citizen scientists and found that nature reserves are 4 times more likely to be colonized than expected, providing vital refuges against climate change.
Wild meerkats employed nine separate learning processes to solve a foraging task, with social factors drawing them in and asocial processes aiding solution. This study provides insight into the relationship between social learning mechanisms and cultural development.
A recent study published in Nature found that many tropical protected areas are struggling to sustain their biodiversity, despite being our best hope for preserving tropical forests. However, the research also highlights the importance of eliminating threats outside park boundaries and maintaining existing parks.
A new report concludes that commercial 'wildlife encounter' operations promoting captive lion reintroduction do little to conserve African lions. Wild-born lions are better equipped for survival and release compared to captive-bred ones. These programs divert critical resources from projects addressing declining wild lion populations.
A Michigan State University study reveals that people's attitudes towards tigers are influenced by benefits and pragmatic costs of having tigers nearby, suggesting a combination of psychological responses drives tolerance.

The discovery highlights the importance of protecting these areas from encroachment and development, which threaten the survival of the species.
A study by Johns Hopkins University and The National Aquarium found that captive dolphins have lower levels of mercury in their systems compared to wild dolphins. This difference was attributed to the diet of the captive animals, which consisted mainly of small fish from North Atlantic waters with lower mercury pollution levels.
A recent study recommends focusing on collecting animal samples from carcasses during Ebola outbreaks, with a 50% success rate compared to less than 6% when sampling live animals. This approach is crucial for early detection and learning more about the virus.
