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...
