Genome Map Hints at How Desert Tortoise Overcomes Natural, Human Dangers

Researchers have finished the first full genome map of the threatened Mojave desert tortoise (Gopherus agassizii), also known as Agassiz’s desert tortoise.

They hope their findings will inform conservation efforts, improve understanding of its evolutionary past and potentially contribute  to  human medicine.

After 30-plus years of wrangling, wildlife managers have yet to agree on a revised recovery plan for the endangered Mexican wolf. As a November deadline looms, a study by the Arizona Game and Fish Department and British Columbia’s Wildlife Genetics International offers guidance for finding common ground.

In one five-year period, college athletes suffered more than 10,000 concussions — one-third of them while playing football. But an unusual team-up has recently brought a new, biomarker-based concussion test one step closer.

Zoo Conservation Center Pulls Native Species Back from the Brink

As Congress eases rules for selling public lands and considers measures to weaken the Endangered Species Act, conservation efforts may rely increasingly on private facilities like the Phoenix Zoo, which supports its Arthur L. and Elaine V. Johnson Foundation Native Species Conservation Center with a portion of its gate receipts.

Zebrafish Make a Big Splash in Arizona Medical Research

Mammals might seem like better human stand-ins than a minnow’s striped cousin, but zebrafish resemble us in surprising and useful ways. But zebrafish also offer practical advantages over other model species: They’re cheap, hardy, breed like rabbits on Viagra, and their skin can be made transparent.
