Keywordslife history, reproductive value, livebearing fishesAbstractThe proposal was to conduct a large-scale mark-recapture project on a livebearing fish in Utah lake to evaluate size and sex-specific mortality rates of this population. The experiment was begun in mid- summer by marking over 1000 individual mosquitofish. All fish were returned to the lake alive after marking. In the original design we would recapture fish at two later intervals – late summer and early spring.

(2015)"The central aim of this proposal is to provide opportunities for students from diverse academic backgrounds to work collaboratively on a number of federally funded environmental change experiments across four of Utah’s ecosystems—Mojave Desert, Great Basin Shrub Steppe, Subalpine Tall Forb, and Colorado Plateau Grassland.

FilesKeywordsHost Parasite Interactions, Copepods, RockfishAbstractHost-parasite interactions are key components in shaping ecosystem and community structure. In parasitism, the host maintains the life of the parasite and can have its fitness influenced as a result. This can be especially problematic for commercial fish projects, as well as species management.
