Anthropogenic environmental change has led to unprecedented rates of species extinction, presenting a major threat to global biodiversity. Among vertebrates, amphibians have been most severely impacted, with an estimated 41% of species now threatened with extinction. In response to this biodiversity crisis, a moral and ethical obligation exists to implement proactive interventionist conservation actions to assist species recovery and decelerate declines. Conservation breeding programs have been… 
Amphibian Assisted Reproductive Technologies: Moving from Technology to Application.
Successful technologies including non-invasive gamete collection, IVF and sperm cryopreservation that work well enough to be applied to many current conservation programs are reviewed and new advances in technology of cryop Reservation of aquatic embryos of fish and some marine invertebrates are considered.
Evolutionary principles guiding amphibian conservation
It is gloomily concluded that extinction seems far more likely than adaptation or range shifts for most species and that an explicit consideration and application of evolutionary principles should increase effectiveness of amphibian conservation in both the short and long term.
Common goals, different stages: the state of the ARTs for reptile and amphibian conservation.
In both amphibians and reptiles, a focus on sperm cryopreservation and artificial fertilisation or artificial insemination has been at the expense of the development and application of more advanced technologies, or the use of sophisticated stem cell/primordial germ cell cryop Reservation and transplantation approaches.
An experimental test of the genetic consequences of population augmentation in an amphibian
The results suggest that inter‐population crosses might be susceptible to genetic incompatibility and outbreeding depression, and it is argued that widespread adoption of this approach will enable more rapid assessment of the risks associated with population augmentation and improve the management of threatened amphibians globally.
Post‐release comparisons of amphibian growth reveal challenges with sperm cryopreservation as a conservation tool
Conservation translocation using captive‐bred individuals has become increasingly important for species restoration. Despite advancements in technologies for captive‐breeding, such as gamete
Amphibian reproductive technologies: approaches and welfare considerations
Mechanisms of the amphibian hypothalamo–pituitary–gonadal axis are reviewed, advances in hormone therapies are discussed and animal welfare considerations are drawn attention.

Overall, the protocols previously developed for Pseudophryne guentheri for hormonally inducing egg release and artificial fertilisation in three additional terrestrial-breeding species of Australian ground frog were considered effective, but further protocol refinement is required for H. eyrei.
Integrating biobanking could produce significant cost benefits and minimise inbreeding for Australian amphibian captive breeding programs
It is shown that back-crossing with frozen founder spermatozoa using ARTs every generation minimises rates of inbreeding and provides considerable reductions in colony size and program costs compared with conventional captive management.
