Biodiversity library will help preserve genetic diversity in endangered species

Researchers can preserve genetic diversity in wildlife by freezing, storing living cells.

The world’s wildlife are facing a barrage of threats caused by climate change, from the loss of suitable habitat to dwindling food supplies. As a result, endangered species across the U.S. are edging closer to extinction at alarming rates—and if they disappear, critical genetic information could vanish with them.

In a new initiative announced on Tuesday, the U.S. Fish & Wildlife Service is working with the nonprofit Revive & Restore and other partners to create a “genetic library” of the country’s endangered species—before it’s too late.

Through a process called biobanking, FWS field staff are gathering biological samples such as blood, tissues and reproductive cells from animals to be cryogenically preserved at extremely low temperatures (at least -256 degrees Fahrenheit) and stored at a USDA facility in Colorado. The samples will also be genetically sequenced and this information will be uploaded to a publicly available database called GenBank, where researchers can study them and compare their genomes to other members of their species.
