Lowland tapirs, the largest terrestrial mammal in South America, have been found thriving in a protected area spanning five national parks. Camera trap data reveals higher abundance under protection than outside, and estimates at least 14,500 individuals exist, making it one of the continent's most important strongholds for conservation.
African sleeping sickness, caused by a brain-invading parasite transmitted by tsetse flies, can persist in areas with no human cases due to wild animal populations. A new study suggests that targeting humans alone may not be enough to control the disease and that efforts must factor in wild animals.
A recent study by EcoHealth Alliance found Ebola virus antibodies in approximately 4% of the bats screened in Bangladesh, indicating that Rousettus fruit bats may be a natural reservoir for Ebola virus. The study extends the known range of Ebola to mainland Asia.

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.
A study by the Wildlife Conservation Society found that intense gas development is driving away wildlife from their traditional wintering grounds. In Wyoming's Jonah and PAPA gas fields, researchers discovered an 82% decline of high-quality habitat for pronghorn, a sharp increase in infrastructure, and behavioral shifts among the animals.
A recent study found that bigger male gorillas are more successful at attracting mates and raising offspring. The research, conducted over 12 years in Nouabalé-Ndoki National Park, revealed positive correlations between physical traits such as head-crest size and gluteal muscles with an adult male's average number of mates.

The disease is believed to have been transmitted from domestic goats, highlighting the need for continuous disease surveillance.
Recent research in Madagascar reveals that illegal hunting of protected species, including lemurs, is widespread due to increasing appetites for meat and declining traditional taboos. The study suggests that improving access to domestic meats and disease control methods can help reduce pressure on wild species.
