A new study reveals that the loss of larger animals in tropical forests diminishes the overall ecosystem biodiversity because of subtle interactions involving those animals and the evolutionary str

For the first time in two decades, cheetahs are wandering in Malawi as the African Parks has reintroduced four cheetahs to Liwonde National Park.

Dengue is the most important arthropod-borne viral infection of humans, it is established in the tropics worldwide, and its geographical expansion is expected to increase due to factors such as modern dynamics of climate change, globalization, travel, trade, poverty, unplanned urbanization, and viral evolution. The World Health Organization (WHO) estimates that 2.5 billion people are at risk of infection, with 50–100 million infections per year.

Arusha — Chimpanzees may soon join elephants and rhinos as the most threatened wildlife species in Tanzania due to their fast falling populations, wildlife experts have said.

New research into what caused extinctions at the end of the last ice age has revealed the life-altering force of warming temperatures on Earth.

In the Salish Sea, the endangered Southern Resident Killer Whale (SRKW) is a high trophic indicator of ecosystem health. Three major threats have been identified for this population: reduced prey availability, anthropogenic contaminants, and marine vessel disturbances. These perturbations can culminate in significant morbidity and mortality, usually associated with secondary infections that have a predilection to the respiratory system.

Cameroon has burned more than three tons of pangolin skins and scales seized from smugglers and destined for Asian countries.

Conservationists are celebrating the successful reintroduction of an iconic antelope species, the scimitar-horned oryx, to a portion of its historical range on the edge of the Sahara desert after 1

The International Fund for Animal Welfare (IFAW) said pangolins are the world's most illegally traded mammal and in danger of extinction.

Although it is widely accepted that future climatic change—if unabated—is likely to have major impacts on biodiversity, few studies have attempted to quantify the number of species whose populations have already been impacted by climate change. Using a systematic review of published literature, we identified mammals and birds for which there is evidence that they have already been impacted by climate change. We modelled the relationships between observed responses and intrinsic (for example, body mass) and spatial traits (for example, temperature seasonality within the geographic range).
