Increases in both the emergence and prevalence of infectious diseases worldwide have substantially impacted wildlife and human health. In order to understand the implications of these trends, it is imperative to determine the underlying factors that structure host and parasite taxa interactions, and the climatological and ecological variables that may influence disease outcomes. The aim of this doctoral dissertation is to address the numerous pathways in which climate change and seasonal weather patterns, as well as biological community dynamics can alter the interactions between hosts and parasites as well as impact both host and parasite populations. Among the most widely observed biological consequences of climate change are shifts in a given taxa's phenological pattern. My first two chapters assess how spatial and temporal variation in phenological overlap between vulnerable host and parasite release explains the differences in observed host pathology. These two chapters demonstrate that host pathology can be highly sensitive to phenological overlap between vulnerable host and infection risk, where host pathology is a product of both infection level and high phenological overlap. Changes in climate patterns can also alter the abundance and distribution of host species, which can have varying degrees of impact on host-parasite interactions. My third chapter assesses how severe drought, invasive species and disease risk influence two native amphibian species. This study revealed limited disease risk, high levels of drought resilience, and a significant influence of invasive species' presence and densities on both species' distributions. Finally, parasites often interact with numerous non-host taxa, several of which can alter a parasite's ability to infect a host, including predators that can actively consume parasites while in a free-living infectious stage (infectious agents). This study assesses how different predator taxa vary in ability to consume infectious agents across a diverse assemblages of parasite taxa.
