LA JOLLA, Calif. (Feb. 26, 2024) – Love is in the water for the critically endangered Sunflower Sea Star as a team in California successfully spawned and cross-fertilized gametes from a male and a female, resulting in fertile eggs. This success marks another incredible step forward in an ongoing collaborative effort to save the species from extinction. This advancement took place at Birch Aquarium at Scripps Institution of Oceanography at UC San Diego, where their experts were joined by partners from the Aquarium of the Pacific, California Academy of Sciences, San Diego Zoo Wildlife Alliance (SDZWA) and Sunflower Star Laboratory.
SAN DIEGO (Feb. 14, 2024) – It's a match! In the world of conservation, pairing a perfect couple is more than just a romantic endeavor; it could be the key to saving an endangered species. San Diego Zoo Wildlife Alliance (SDZWA) is playing Cupid for the critically endangered ‘alalā, a unique bird found only in Hawai‘i. In a new, unconventional study recently published in the journal Animal Conservation, SDZWA scientists hoping to hone their matchmaking skills applied personality traits to these crow relatives to find love connections to result in successfully fertilized eggs.

SAN DIEGO (Jan. 9, 2024) – To apply cutting-edge technology to the conservation of koalas, San Diego Wildlife Alliance is partnering with Illumina, a leading genomic sequencing technology company, through the Illumina iConserve program to sequence the whole genomes (an individual’s complete set of DNA) of nearly 100 koalas residing in North America over the past 30 years. Whole genome sequencing is integral to learning more about Koala Retrovirus, KoRV – a virus that can insert into the koala genome and is associated with various health issues in koalas including immunosuppression and cancer.
SAN DIEGO (Dec. 19, 2023) – For more than a decade, the San Diego Zoo Wildlife Alliance’s entomology team has collaborated with Australia’s Melbourne Zoo to maintain populations of the critically endangered Lord Howe Island stick insect. For the first time in North America, visitors to the San Diego Zoo will have the opportunity to see these rare, nocturnal insects in a specialized habitat at the Zoo’s Wildlife Explorers Basecamp.
SAN DIEGO (Nov. 14, 2023) – San Diego Zoo Wildlife Alliance, in collaboration with Omaha’s Henry Doorly Zoo and Aquarium, reintroduced more than 70 endangered mountain yellow-legged frogs into a lake located in the San Bernardino Mountains. This release marks the first time the Southern California distinct population segment of the mountain yellow-legged frog has been reintroduced into a lake instead of a mountain stream. The frogs were bred at San Diego Zoo Wildlife Alliance’s Beckman Center for Conservation Research between 2020 and 2022, and then reared at Omaha’s Henry Doorly Zoo and Aquarium. The cross-country effort to save this California frog is part of a robust conservation breeding and reintroduction research program aimed at restoring populations of this declining species throughout its historic range.

SAN DIEGO (Nov. 9, 2023) – A binational team of scientists, using creativity and innovation, adorned dozens of endangered thick-billed parrots with tiny solar-powered satellite transmitters to track and reveal their winter migratory nesting sites in the remote treetops of the Sierra Madre Occidental ranges. Their research reveals new critical habitat, 80% of which has no formal protection.
