Conservation translocation using captive‐bred individuals has become increasingly important for species restoration. Despite advancements in technologies for captive‐breeding, such as gamete cryopreservation, it remains largely unknown if these artificially‐produced offspring can be used to establish a viable wild population. Using an amphibian species with a stable conservation status (Anaxyrus fowleri), we measured the post‐release growth and survivorship of offspring produced from frozen… 
Bridging the Research Gap between Live Collections in Zoos and Preserved Collections in Natural History Museums
Abstract Zoos and natural history museums are both collections-based institutions with important missions in biodiversity research and education. Animals in zoos are a repository and living record of


The Role of Reproductive Technologies in Amphibian Conservation Breeding Programs.
The role of reproductive technologies in amphibian conservation breeding programs is discussed and technological advancements in amphibians hormone therapies, gamete storage, and artificial fertilization are summarized.
Breakthroughs and new horizons in reproductive biology of rare and endangered animal species
The optimization of new tools and approaches spanning from new biomarkers to bioinformatics will help to accelerate the exploration of wildlife reproduction and understand how it is impacted by environmental factors.
Quantifying Ecological Life Support: The Biological Efficacy of Alternative Supplementation Strategies for Imperiled Amphibian Populations
Global biodiversity loss has prompted diverse efforts to stem or reverse declines for many species. Such efforts are often implemented before the efficacy of alternative management actions is
Reproduction biotechnologies in germplasm banking of livestock species: a review.
Why the preservation of genetic diversity is needed for livestock and fish, and some of the issues involved in germplasm banking are described, are described.
Cryopreservation of semen from domestic livestock.

A greater role for the use of frozen semen in livestock production can come only from an improvement in the preservation of the functional competence of the cryopreserved spermatozoon after insemination into the female tract.
Sperm Cryodamage in Ruminants: Understanding the Molecular Changes Induced by the Cryopreservation Process to Optimize Sperm Quality
The molecular basis of those factors that can affect the sperm freezing resilience of different ruminant species is discussed as well as the molecular aspects of those novel strategies that have been developed to reduce sperm cryodamage, including new cryoprotectants, antioxidants, proteins, nanoparticles and vitrification.
Cryopreservation and vitrification of fish semen: a review with special emphasis on marine species
The object of this review was to provide recent data on semen cryopreservation in marine fish species and to suggest variables which may be applied in future research.
Viability analysis of a threatened amphibian population: modelling the past, present and future
The models suggest that populations that are responding to management against a background of natural fluctuations may remain vulnerable to extinction for several decades, if habitat management fails to offset reductions in recruitment and juvenile survival caused by environmental change.
