Nearly one-third of all amphibian species globally are at risk of going extinct. While the global amphibian crisis is the result of habitat loss, climate change and pollution, the deadly amphibian chytrid fungus plays a large role in the frogs' disappearances. In the fight for frogs, Smithsonian Conservation Biology Institute (SCBI) biologist Brian Gratwicke and partners are making strides in finding a cure for chytridiomycosis disease with the help of probiotics.

What happens when a species is restored to its rightful place in the wild? In the case of the scimitar-horned oryx, the answer to that question has been nearly 30 years in the making. Next month, 25 oryx will be released to a large reserve in Chad, a country where they have been extinct in the wild since the mid-1980s. Each reintroduced oryx will sport a GPS collar that has been fitted and tested by Smithsonian Conservation Biology Institute scientists. In the Q&A below, scientists Mel Songer and Jared Stabach share how SCBI has prepared for this ambitious and historic recovery effort.

As their native habitat continues to shrink, wild cheetahs are facing a drought of genetic diversity. This is in direct contrast with the population of cheetahs in zoos, which is as genetically diverse as it was 30 years ago because of cooperative and strategically managed breeding programs. This is according to a new study from the Smithsonian Conservation Biology Institute (SCBI) and partners published June 21 in the journal Biological Conservation. SCBI cheetah biologist Adrienne Crosier and Kim Terrell, lead author on the study, former SCBI doctoral student and current director of research and conservation at the Memphis Zoo, talk about what their findings mean for the future of cheetahs.
