SAN DIEGO (Nov. 30, 2023) – Scientists at San Diego Zoo Wildlife Alliance have achieved a major milestone in saving wildlife species: With a blue-eyed black lemur’s cells recently added to its Wildlife Biodiversity Bank’s Frozen Zoo®, the nonprofit conservation organization’s unique collection of genetic material now contains 11,00o individual cell lines from more than 1,250 species and subspecies—some critically endangered. No other biobank in the world has a comparable number of living cell lines, with the potential to reverse losses of genetic diversity and contribute to population sustainability for  endangered and threatened wildlife species.

SAN DIEGO (Nov. 27, 2023) – When a mysterious illness called “sea star wasting syndrome” decimated 95% of the sunflower sea star population, and some 20 other sea star species along the Pacific Coast from Baja to Alaska in 2013, scientists rallied to understand the factors that caused such a massive wasting event. Now as part of the greater recovery initiative, in a scientific first, dozens of baby sunflower sea stars were hatched and are thriving thanks to a breakthrough in reproductive cell cryopreservation technology.

Their birth also comes just in time for Global Tiger Day. With only an estimated 400 to 600 Sumatran tigers remaining on Earth, the births are significant in increasing the worldwide population of this tiger species and furthering the nonprofit conservation organization’s ongoing work to conserve them.

SAN DIEGO (July 13, 2023) – After more than two years of dedicated work, San Diego Zoo Wildlife Alliance conservationists are achieving success breeding a critically endangered coastal bird: the milky stork. This breeding program is part of an 11th-hour effort with the Association of Zoos and Aquariums Taxon Advisory Group (AZA TAG) to assist the last remaining individuals of the species living in North America—helping them successfully reproduce, and bolster the world’s population of milky storks.
