Coral cryopreservation for breeding key to survival

Flash-frozen sperm collected from corals in Florida and Puerto Rico was used to fertilize coral eggs from hundreds of miles away in Curaçao. The juvenile corals raised from this trans-Caribbean coupling demonstrate the reproductive ...

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.
