Hormonal induction and seasonal variation in male reproductive viability of the Southern Rocky Mountain boreal toad.

The Southern Rocky Mountain boreal toad (Anaxyrus boreas boreas) depends on both the rearing of wild-collected egg masses and a long-standing conservation breeding program (CBP), the latter of which heavily relies on assisted reproductive technologies (ARTs) to support wild populations. Achieving consistent reproductive success in the CBP, however, remains a significant challenge. Natural breeding has not led to a sustained increase in reproductive capacity, prompting the exploration of exogenous hormone treatments as an alternative strategy.

Common goals, different stages: the state of the ARTs for reptile and amphibian conservation.

Amphibians and reptiles are highly threatened vertebrate taxa with large numbers of species threatened with extinction. With so many species at risk, conservation requires the efficient and cost-effective application of all the tools available so that as many species as possible are assisted. Biobanking of genetic material in genetic resource banks (GRBs) in combination with assisted reproductive technologies (ARTs) to retrieve live animals from stored materials are two powerful, complementary tools in the conservation toolbox for arresting and reversing biodiversity decline for both amphibians and reptiles.

Evaluating amphibian biobanking and reproduction for captive breeding programs according to the Amphibian Conservation Action Plan objectives.

The Amphibian Conservation Action Plan (ACAP), published in 2007, is a formal document of international significance that proposed eleven relevant actions for global amphibian conservation. Action seven of the ACAP document addresses the use of amphibian captive programs as a conservation tool. Appendix material under this action explores the potential use of Genome Resource Banking (biobanking) as an urgently needed tool for these captive programs.

Sperm collection and storage for the sustainable management of amphibian biodiversity.

Current rates of biodiversity loss pose an unprecedented challenge to the conservation community, particularly with amphibians and freshwater fish as the most threatened vertebrates. An increasing number of environmental challenges, including habitat loss, pathogens, and global warming, demand a global response toward the sustainable management of ecosystems and their biodiversity. Conservation Breeding Programs (CBPs) are needed for the sustainable management of amphibian species threatened with extinction.
