Captive breeding in the endangered alpine tree frog, Litoria verreauxii alpina [PDF]
PeerJ, 2023 Amphibians are experiencing dramatic worldwide declines and many species are reliant on captive breeding programs to ensure continued survival. However, captive breeding in amphibians is not always successful because many species, especially ones in ...

Genetic effects of long-term captive breeding on the endangered pygmy hog [PDF]
PeerJ, 2021 Long-term captive populations often accumulate genetic changes that are detrimental to their survival in the wild. Periodic genetic evaluation of captive populations is thus necessary to identify deleterious changes and minimize their impact through ...

Effects of domestication and captive breeding on reaction to moving objects: implications for avoidance behaviours of masu salmon Oncorhynchus masou [PDF]
Royal Society Open Science, 2023 Domestication and captive breeding can compromise the obstacle- and predator-avoidance capabilities of animals in the wild. Whereas previous studies only examined these effects in combination, here we examine them individually by comparing the abilities ...

Securing genetic integrity in freshwater pearl mussel propagation and captive breeding [PDF]
Scientific Reports, 2021 Securing genetic integrity is of key importance in conservation-oriented captive breeding programs releasing juveniles into the wild. This is particularly true for species such as the endangered freshwater pearl mussel (Margaritifera margaritifera) for ...

Sperm morphology and forward motility are indicators of reproductive success and are not age- or condition-dependent in a captive breeding population of endangered snake. [PDF]
PLoS ONE, 2023 The relationship between male ejaculate traits and reproductive success is an important consideration for captive breeding programs. A recovery plan for the endangered Louisiana pinesnake includes captive breeding for the release of young to the wild ...

Maternal behavioural analysis during a successful captive breeding of jaguars Panthera onca
Theriogenology Wild, 2023 The breeding of captive wild species can play a crucial role in their preservation. Jaguars, the largest felines in the Americas, face challenges in captivity that hinder their breeding success in zoos and conservation institutions.

Diversity, 2021 Many species are threatened with extinction, and captive breeding programs are becoming more common to avoid this outcome. These programs serve to prevent extinction and produce individuals for eventual reintroduction to natural populations in historical
