Current estimates of the number of cheetahs in the wild are `guesswork', researchers, including those from India have found, amid fears that the fastest land mammal is racing to extinction.

The diversity of life on Earth—which provides vital services to humanity —stems from the difference between rates of evolutionary diversification and extinction. Human activities have shifted the balance : Species extinction rates are an estimated 1000 times the “background” rate and could increase to 10,000 times the background rate should species threatened with extinction succumb to pressures they face.

The dry forests of Cambodia once serve as the home for a number of Indochinese tigers, but now, due to excessive human activities, World Wildlife Fund (WWF) has declared tigers to be "functionally"

Nashik: The majestic Great Indian Bustards (GIBs) are vanishing from sight, at least in the Nashik region.

China’s lucrative black market for fish parts is threatening the vaquita, the world’s most endangered marine mammal.

Biologists have described a new species of extinct plant, based on two fossil flowers that were trapped in chunks of amber for at least 15 million years.

Large herbivores and carnivores (the megafauna) have been in a state of decline and extinction since the Late Pleistocene, both on land and more recently in the oceans. Much has been written on the timing and causes of these declines, but only recently has scientific attention focused on the consequences of these declines for ecosystem function.

The biggest ape to roam the Earth went extinct 100,000 years ago because the species was not able to adapt to just consuming savannah grass after climate change hit its favoured diet of forest frui

Southwest China's Tibet autonomous region has seen its wildlife population increase in recent decades thanks to protective measures.

The extinction of large animals from tropical forests could lead to potentially stronger impacts of climate change, a new study warns.
