Biodiversity of insects is threatened worldwide.

Australia officially declared a Great Barrier Reef rodent extinct on Tuesday, making it the first mammal believed to have been killed off by human- induced climate change.

Paleontologists are begging the New Zealand government to immediately halt the trade in the priceless bones of the extinct moa bird, fearing that millions of years of science is disappearing as ent

Determining whether species have gone extinct requires considering the timing and reliability of records, the timing and adequacy of surveys, and the timing, extent and intensity of threats. However, previous assessments have either applied qualitative approaches or considered only the first of these factors. We applied quantitative methods encompassing all three factors to a suite of 61 potentially or confirmed extinct species of birds.

Researchers from Aarhus University and University of Gothenburg have produced the most comprehensive family tree and atlas of mammals to date, connecting all living and recently extinct mammal spec

Almost every species of lemur, wide-eyed primates unique to Madagascar, are under threat of extinction.

A deadly disease is threatening to wipe out frogs and toads, a new report has shown.

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.

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.
