More than two-thirds of mammals in Africa and the Arabian Peninsula went extinct during the Eocene-Oligocene transition some 30 million years ago, a study finds.

A modeling study estimates that by drastically reducing fish biomass over the past century, industrial fishing may be affecting ocean chemistry, nutrient fluxes, and carbon cycling as much as climate change.

Warmer temperatures are likely to increase the prevalence of the mosquito-borne disease in many places, but not all.

The Princeton University evolutionary biologist studies how animals are changing due to human activity.

The United Nations Intergovernmental Panel on Climate Change says some changes are already irreversible, and warns of even more dire ramifications if global carbon emissions aren’t reduced immediately.

A recent sampling from two California streams found nearly all juvenile salmon were infected with deadly parasites, and conditions are expected to worsen.

Brood X’s emergence tunnels—numbering in the hundreds per square meter of soil—give researchers a special opportunity to study how such extreme soil aeration affects the ecosystem.

Researchers find a widespread decline in dissolved oxygen levels in lakes, which is known to reshape ecosystems.

A study proposes that habitat for bats—and their accompanying coronaviruses—has increased in southern Asia over the last century, but experts debate the reliability of the analysis.

Blue sharks don't dive as deeply in low-oxygen waters—which become more prevalent as oceans warm—effectively pushing them into areas of high fishing pressure.
