<unk>  is a sub-discipline of<unk>  concerned with the mechanisms, patterns, and effects of host-pathogen interactions, particularly those of infectious<unk> s. For example, it examines how parasites spread through and influence wildlife populations and communities. By studying the flow of<unk> s within the natural environment, scientists seek to better understand how changes within our environment can shape how pathogens, and other<unk> s, travel. Therefore,<unk>  seeks to understand the links between<unk> cal interactions and<unk>  evolution. New emerging and re-emerging infectious<unk> s (infecting both wildlife and humans) are increasing at unprecedented rates which can have lasting impacts on public health, ecosystem health, and biodiversity.
