Linking Husbandry And Behavior To Enhance Amphibian Reintroduction Success, Luke Jack Linhoff
FIU Electronic Theses and Dissertations
Wildlife in captivity has a long history of benefiting global conservation goals. Captive animals can raise awareness and appreciation for the conservation of endangered species. Additionally, captive animals can be used as source populations to reintroduce animals back to the wild or to supplement existing wild populations. The rapid increase in amphibian species threatened with imminent extinction has necessitated the creation of dozens of captive-breeding programs. The focus of this dissertation has integrated topics across the spectrum of animals in captivity and the wild, and the results provide useful recommendations for conservation action. First, I describe how market pressures over …

Proceedings of the North American Crane Workshop
Captive-bred Mississippi sandhill cranes (Grus canadensis pulla) suffer from low recruitment in nature, and poor nest defense ability may significantly contribute to the problem. We hypothesized that a lack of opportunities for social learning by young birds prior to release inhibits the development of appropriate nest defense in later life. Here we report the results of preliminary experiments on conditioning of antipredator behavior in young birds prior to release using predator models. Observing agonistic displays by either costumed technicians or parent birds toward a model raccoon (Procyon lotor) promoted aggressive displays to a wild raccoon, but …
