Evolution and classification of bibionidae (Diptera: Bibionomorpha)

Creator:: Fitzgerald, Scott J.
Abstract:: 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...

Taxonomy and evolution of the Orthotyline genus Lopidea (Heteroptera: miridae)

Creator:: Asquith, Adam
Abstract:: The genus Lopidea Uhler is revised for America north of Mexico. The relationship of Lopidea to other orthotyline genera is discussed and it is proposed that the genus Ilnacora Reuter is the sister group of Lopidea. Forty-eight species of Lopidea are recognized in North America, one of which is described...

Population and production ecology of Lipsothrix spp. (Diptera:Tipulidae)

Creator:: Dudley, Thomas L.
Abstract:: Craneflies of the genus Lipsothrix inhabit decomposing wood in streams. The life cycles and ecological relationships of L. nigrilinea (Doane) and L. fenderi Alexander were investigated to determine how they exploit and respond to the wood habitat and their role in degradation of woody debris in western Oregon. Surveys of...

Abundance and community composition of arboreal spiders : the relative importance of habitat structure, prey availability and competition

Creator:: Halaj, Juraj
Abstract:: This work examined the importance of structural complexity of habitat, availability of prey, and competition with ants as factors influencing the abundance and community composition of arboreal spiders in western Oregon. In 1993, I compared the spider communities of several host-tree species which have different branch structure. I also assessed...

Negative effect of purple loosestrife and reed canary grass on the diversity of wetland plant and moth communities

Creator:: Schooler, Shon
Abstract:: 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...

Evolution of aposematic warning coloration in parasitic wasps (Hymenoptera:Braconidae)

Creator:: Leathers, Jason Wayne
Abstract:: Many Hymenoptera, with their painful stings and noxious chemical defenses, exhibit bright aposematic warning color patterns and are the most frequently mimicked group of organisms. Such aposematic color patterns are found in parasitic wasps of the Neotropical Compsobracon group (Braconidae). Many members of this group exhibit color patterns similar to...

Ecology of the predatory mite, Pergamasus quisquiliarum Canestrini (Acari: Mesostigmata)

Creator:: Groth, Eric M.
Abstract:: Pergamasus quisquiliarum Canestini is a polyphagous predatory mite that has been shown to feed on the economically important arthropod, Scutigerella immaculata Newport (Symphyla: Scutigerellidae), Collembola, Diptera larvae, Enchytraeid worms, and miscellaneous other soil organisms. This study examined the feeding behavior of P. quisquiliarum, the effects of cover cropping and tillage...

Nutritional ecology of millipedes in Pacific Northwest conifer forests

Creator:: Baumeister, Nancy C.
Abstract:: Comminution of forest leaf litter by millipedes affects litter decomposition and nutrient cycling. The millipede Harpaphe haydeniana Wood (Polydesmida: Xystodesmidae) is common in low to mid-elevation forests on the Pacific Coast of North America. In a series of experiments, the suitability of broadleaf and conifer tree litters for growth of...

The ecology of Chironomidae associated with stabilization lagoons

Creator:: Sturgess, Brian Thomas
Abstract:: Chironomidae occurring in stabilization lagoons were studied from 1964 to 1966 in Oregon. Observations of other insects and their impact on the lagoon environment are included. Quantitative data were obtained from two lagoons near Corvallis and qualitative observations from preliminary work on two other lagoons are reported. The objectives of...
