Behavioral And Hormonal Flexibility Across Light Environments In Guppies (Poecilia Reticulata), Julia C. Walz Aug 2014

Behavioral And Hormonal Flexibility Across Light Environments In Guppies (Poecilia Reticulata), Julia C. Walz

Master's Theses

Behavior may be dramatically influenced by changing environments, and differences in light intensity environments may have important behavioral consequences. One approach to understanding changes in behavior is by studying behavioral syndromes, suites of correlated behaviors reflecting between individual consistencies in behavior expressed within a behavioral situation (e.g., correlations between antipredator behaviors in different habitats), or across behavioral contexts (e.g., correlations among feeding, antipredator, or mating behavior) (Sih et al. 2004a). Guppies (Poecilia reticulata) provide a great model system to study behavior. Guppies are small, freshwater tropical fish that inhabit still pools in swift-flowing streams, and the backwaters of small rivers …


Effects Of Audible Human Disturbance On Koala (Phascolarctos Cinereus) Behavior In Queensland, Australia And Implications For Management, Galina Eugenia Kinsella Jan 2014

Effects Of Audible Human Disturbance On Koala (Phascolarctos Cinereus) Behavior In Queensland, Australia And Implications For Management, Galina Eugenia Kinsella

Honors Theses and Capstones

As the growing human population continues to encroach on wildlife habitat, species are forced to adapt in order to survive. In addition to causing habitat loss, human presence can create more subtle disturbances, such as noise pollution, that disrupt wildlife behavior. Adapting to human presence is particularly difficult for species with specialized resource needs or low mobility. The koala (Phascolarctos cinereus), a national icon of Australia, meets both these criteria. Koalas were once abundant throughout Australia, but are now classified as “threatened.” Habitat loss is at least partly responsible for this decline, but anthropogenic noise may also be …
