SAN DIEGO (April 19, 2023) – Scientists are elated with the recent birth of the world’s second successfully cloned Przewalski’s horse, supporting the concept that cloning can be used as a viable tool for genetic rescue and contribute to new options for fostering resilience and genetic sustainability of endangered species. The foal, born Feb. 17, 2023 to a domestic surrogate mare, is a clone of a male Przewalski’s horse stallion whose living cell line was cryopreserved over 40 years ago in the San Diego Zoo Wildlife Alliance Biodiversity Bank’s Frozen Zoo^®.

For Andean bear conservation efforts to work, scientists must study the varying landscapes as well.

SAN DIEGO (Aug. 17, 2022) – Orphaned animals of several mammal species suffer socially and physiologically, and even if their mother dies after weaning, they may have lower survival than non-orphans. One physiological consequence of orphaning – stunted growth – had been discovered in humans and chimpanzee orphans.  A new study, published recently in the journal Conservation Physiology, shows that orphaning also stunts the growth of African elephants by an estimated average of 13 centimeters.

SAN DIEGO (May 18, 2022) – A new study has found contaminants that were banned decades ago are still imperiling critically endangered California condors. The condors may be at increased risk for reproductive impairment because they consume dead marine mammals along the California coast.

Leopard conservation requires a strategy as multifaceted as the species itself.
