Several decades of seemingly unrelated policies, ranging from increases in elk hunting to the reintroduction of wolves, have combined to cut a population of mountain lions in the western United Sta

Human-induced environmental and climate change are widely blamed for causing rapid global biodiversity loss, but direct estimation of the proportion of biodiversity lost at local or regional scales are still infrequent. This prevents us from quantifying the main and interactive effects of anthropogenic environmental and climate change on species loss.

In collaboration with a nature reserve in Namibia, researchers funded by the SNSF are developing a new approach to counting animals: combining drone flights and automated image analysis.

The mode and tempo of extinctions and extirpations after the first contact phase of human settlements is a widely debated topic. As the last major landmass to be settled by humans, New Zealand offers a unique lens through which to study interactions of people and biota. By analyzing ancient DNA from more than 5,000 nondiagnostic and fragmented bones from 38 subfossil assemblages, we describe species and patterns that have been missed by morphological approaches.

Populations of much-loved British mammals including hedgehogs and water voles have dropped by up to two-thirds over the past 20 years, and many more are threatened with imminent extinction.

The Zambian government on Tuesday denied reports that it has authorized the culling of 2,000 hippopotamuses in a national park with a high population of the mammals.

A team of scientists mined previous studies for estimates of the total mass of carbon found in each group of organisms on Earth as a way to measure relative biomass.

Since the late Pleistocene, large-bodied mammals have been extirpated from much of Earth. Although all habitable continents once harbored giant mammals, the few remaining species are largely confined to Africa. This decline is coincident with the global expansion of hominins over the late Quaternary. Here, we quantify mammalian extinction selectivity, continental body size distributions, and taxonomic diversity over five time periods spanning the past 125,000 years and stretching approximately 200 years into the future.

The scientific models that ecologists and conservation biologists rely on to determine which species and habitats to protect lack critical information to help them make effective decisions, accordi

Four mammals – including the northern hairy-nosed wombat and the numbat – have been upgraded to endangered or critically endangered on the updated Australian threatened species list published on Th
