The Summer Undergraduate Research Fellowship (SURF) Symposium
Captive breeding protocols used in zoos often are aimed at increasing population sizes and retaining genetic diversity of endangered species. However, captive breeding causes genetic adaptation to captivity that can lead to an overall decrease in genetic diversity and reduce chances of a successful reintroduction to the wild. In this study, we assess how 3 different breeding protocols—random mating, preferential breeding of individuals with the lowest mean kinship scores, and selection for docility—affect the variability of mitochondrial DNA in white-footed mice (Peromyscus leucopus). We used mice that were captured from the wild but were mated for up to …

1. The practice of deliberately moving animals from one site to another for conservation is increasing as a tool to re-establish extirpated populations. Resource managers are faced with developing strategies for reintroduction attempts, but often lack experimentally derived evidence upon which to base decisions. 2. Using the northern water snake Nerodia sipedon sipedon in the USA, we compared the behaviour and performance of resident snakes with that of individuals translocated directly from the wild to a nearby nature reserve or reared in captivity prior to translocation. 3. Both translocated groups had low survivorship relative to resident snakes, but the proximal …
