As koalas in southern Australia have grown from a few hundred to almost half a million, the marsupials show signs of regaining lost genetic variation.

The genome of a once-endangered songbird shows extensive signs of inbreeding, according to a new study. Because inbreeding can negatively impact survival and reproduction, the results could guide ...

The small size and isolation of the endangered population of Southern Resident killer whales in the Pacific Northwest have led to high levels of inbreeding. This inbreeding has contributed to their ...

"Fifty years from now, will there be Masai giraffes? I don't know. I think it's a 50/50 proposition," Douglas Cavener, who has published a new study on the risks facing the species, told Live Science.

SEATTLE — A study released Monday found that a group of Southern Resident killer whales found off the west coast may be dying because of inbreeding, substantially impacting their lifespan. The study’s ...

These findings could be used to prevent plant inbreeding and promote genetic diversity in future conservation efforts.

More inbred individuals in two populations of eastern massasaugas have lower reproductive output and survival. Measures to restore genetic fitness to these populations may be needed to prevent local ...
