Lescroart, Nogales-Ascarrunz, et al. demonstrate that the contentious tiger cat species complex consists of five cryptic species. Based on analyses of 38 whole genomes from the Neotropical cat genus L...

Human impacts substantially affect our ability to detect and understand natural biodiversity patterns.

Many of the functional traits that mediate extinction risk across the range of biodiversity relate indirectly to a species’ ability to persist in a changing world, yet certain traits such as colorati...

Short-chain fatty acids (SCFAs) are bacterial metabolites with crucial roles in host homeostasis and immune system modulation. Given their benefits, they have been proposed as markers of healthy micro...

Insects are declining across Europe. Czech scientists have determined this decline can be mitigated by returning large ungulates—horses, aurochs cattle, and wisents—to landscapes. This has been shown ...

Between 50,000 and 10,000 years ago, many of the world’s largest mammals disappeared. Picture creatures like saber-toothed cats with 7-inch fangs and elephant-sized sloths. A new study reveals h...

Bioindication reveals a 60-year shift toward denser, more productive vegetation, but a weak thermophilization signal.

Scientific Reports - Faunal exploitation at the elephant hunting site of Lehringen, Germany, 125,000 years ago

Indigenous knowledge confirms a trend scientists have observed- large bird populations are declining faster than small birds.

Do ravens follow wolves to feed on their kills? For decades, biologists assumed they did. Ravens are often seen flying with wolves, following their tracks, or gathering quickly at fresh carcasses A t...

Global vertebrate populations decline faster in the presence of multiple threats compared to single threats.

Humans have drastically reduced avian diversity, with the majority of extinctions occurring on islands. Previous studies have quantified various aspects of this decline, including both taxonomic and ...
