Members of the tribe Sabethini (Diptera: Culicidae) oviposit and develop in phytotelmata (plant-held waters) and are primarily distributed in a pantropical pattern. Recent cladistic studies have demonstrated that while the tribe is monophyletic, three of its 13 genera are not. The genus Wyeomyia is particularly problematic and debate among culicidologists...
The family Bibionidae has a worldwide distribution and includes
approximately 700 species in eight extant genera. Recent studies have not produced
compelling evidence supporting Bibionidae as a monophyletic group or identified the
sister group to bibionids. Therefore, the purpose of this study is to examine the
classification and evolution of...
This dissertation describes arthropod responses to and effects on decay processes in
ponderosa pine, a dominant forest canopy tree in northern California. We used both
descriptive and experimental field techniques to establish how arthropod assemblages
depend on and are important to the disintegration of woody structures in forests of this...
Invasive plants have the potential to reduce the diversity of species in plant and animal
communities. I examined the negative effect of two invasive wetland plants, purple loosestrife and reed
canary grass, on the species richness and diversity of plant and moth communities within 24 wetland study
sites in the...
