Ecological aspects of kin discriminating behavior with implications of functional value

Creator:

Hokit, D. Grant

Abstract:

To assess the context dependence of kin discriminating behavior, I examined kin-biased aggregation behavior in tadpoles of R. cascadae in different ecological conditions. I manipulated food distribution, predator presence, thermal heterogeneity, and relatedness in a multifactorial mesocosm experiment. All four factors interacted to influence tadpole dispersion. My results suggest that...

The effects of pathogens, UV-B radiation, and introduced species on amphibians in the Pacific Northwest

Creator:

Kiesecker, Joseph Michael

Abstract:

I examined two amphibian communities to assess factors that may impact amphibian biodiversity. The results suggest that the potential factors which influence the maintenance of amphibian biodiversity are multi-faceted and thus, attempts to understand these factors must reflect these complexities. I investigated factors that influenced the susceptibility of western toad...

Effects of Diversity on Emerging Infectious Diseases of Amphibians

Creator:

Snyder, Paul W.

Abstract:

Species declines and extinctions have been recorded across taxa as evidence of an ongoing global biodiversity crisis. Amphibians are at the forefront of these declines with nearly one third of amphibian species estimated to be at risk of extinction. While many factors contribute to population declines and extinctions, the role...
