Researchers find that conserving marsupials on a predator-free island dampens their avoidance behaviors, which could mean trouble for their reintroduction to mainland Australia.

During the last ice age, there wasn’t much plant matter to eat on northern steppes, but herbivorous woolly mammoths were abundant. How did they survive?

Scientists are searching for signatures of mammals within the blood meals of the invertebrates.

A species of water flea in northern Belgium that helps keep algae in check is growing smaller and less abundant in urbanized areas. 

The reef has bounced back from “death events” in the past, but that doesn’t mean it will be resilient over the next few decades.

The University College London researcher investigated how environmental pressures affect animals.

The Chinese giant salamander is not one but five different species.

Bigger, older mothers produce disproportionately more eggs than their smaller counterparts do.

If left unchecked, greenhouse gas emissions will drive ocean temperatures up, affecting wildlife in these regions.

Given the speed and efficiency of environmental (eDNA) sampling, a much larger portion of the sea can be screened, in a shorter time, for patterns of diversity.

Research suggests that the invasive, all-female Procambarus virginalis originated in a German aquarium back in the 1990s.

A group of around 300 whales produced 184 distinct songs over just a few years, according to a new study.

Social insects kill infected individuals for the benefit of the colony—and now a study has shown how they know who’s sick.

A controversial hypothesis suggests that jellyfish may one day rule the oceans, and Mola mola may tell us if we are approaching a tipping point.

Researchers pinpoint a protein that can metabolize at least one of the insecticides, highlighting a route to identifying compounds that are friendlier to the critical pollinators.

In an unusual evolutionary twist, local stick spiders have come up with an almost identical repertoire of color morphs in multiple locations.

The elimination of the biting pests was an added bonus after researchers unleashed a rat-eradication endeavor on the tiny islands.  

Poecilia formosa, an all-female fish species, has a surprisingly robust genome. 

Puerto Rico’s Cayo Santiago has hosted decades of research in cognition, primatology, immunization, and other areas.
