Conservation breeding programs (CBPs) for threatened salamander species depend on reliable reproduction. We followed ovarian maturation and oviposition in eastern tiger salamander (Ambystoma tigrinum) females treated with exogenous hormone regimens d

Abstract The Chiricahua leopard frog (Lithobates chiricahuensis) is a threatened species endemic to the southwestern United States and Northern Mexico. Captive breeding programs were established to support reintroduction efforts, yet reproductive out

Abstract Background With Panamanian golden frogs (Atelopus zeteki; PGFs) likely extirpated from the wild, ensuring long-term sustainability of captive populations is crucial in order to conserve this critically endangered species. Unfortunately, PGFs

Abstract Genetic variation of the endangered Puerto Rican crested toad (PRCT; Peltophryne lemur) has dwindled over time in both wild and captive populations, leading to long‐term sustainability issues for the recovery program. To address this chall

Sperm cryopreservation and biobanking are emerging as tools for supporting genetic management of small and threatened populations in amphibian conservation programs. However, there is little to no evidence demonstrating reproductive maturity and viab

Abstract Background Declining amphibian populations around the world necessitate the establishment of captive assurance colonies as a hedge against extinction. For species that are difficult to breed in captivity, assisted reproductive techniques, su

More than 50% of caudates are threatened with extinction and are in need of ex-situ breeding programs to support conservation efforts and species recovery. Unfortunately, many salamander populations under human care can experience reproductive failur

Conservation programs for threatened high- elevation amphibian species rely on hibernation to trigger appropriate male reproductive behaviours and gametogenesis. Although common practice and anecdotal observations have supported the practice of hiber

Asynchrony of gamete release is problematic in amphibian captive breeding programs but can be overcome by short-term storage of spermatozoa. Hormonally induced sperm from the model species Anaxyrus fowleri were used to determine storage conditions fo
