Genome sequencing reveals a new species of bumblebee

While studying genetic diversity in bumblebees in the Rocky Mountains, U.S., researchers from Uppsala University discovered a new species. They named it Bombus incognitus and present their findings in the journal Molecular ...

Crocodile evolution rebooted by Ice Age glaciations

Crocodiles are resilient animals from a lineage that has survived for over 200 million years. Skilled swimmers, crocodiles can travel long distances and live in freshwater to marine environments. But they can't roam far overland. ...

Speciation in the presence of gene flow

Spatial isolation is known to promote speciation—but LMU researchers have now shown that, at least in yeast, the opposite is also true. New ecological variants can also evolve within thoroughly mixed populations.

Elephant genetics guide conservation

A large-scale study of African elephant genetics in Tanzania reveals the history of elephant populations, how they interact, and what areas may be critical to conserve in order to preserve genetic diversity for species conservation. ...

Partial autonomy—how species separate, but not entirely

The prevailing theory until now suggests that regular gene flow through successful pairings between populations is the main barrier to their segregation into species. In recent years, however, theoretical and empirical work ...

Chronically understudied, fences hold grave ecological threats

Fences are one of humanity's most frequent landscape alterations, with their combined length exceeding even that of roads by an order of magnitude. Despite their ubiquity, they have received far less research scrutiny than ...
