The biology and behavior of the alkali bee Nomia melanderi Cockerell (Hymnoptera:Apoidea)

Creator:: Hackwell, Glenn Alfred
Abstract:: Nomia melanderi Cockerell is one of the most efficient pollinators of alfalfa in Eastern Oregon. Emergence begins in June, usually reaches its peak in early July, and may continue into early August. Male emergence precedes female emergence by four or five days. For the first few weeks of this time,...

Etiology and pathogenesis of chalkbrood in the alfalfa leafcutting bee, Megachile rotundata

Creator:: Vandenberg, J. D. (John Donald)
Abstract:: Chalkbrood is a mycosis of larvae of the alfalfa leafcutting bee, Megachile rotundata (Fabricius). It is a serious threat to alfalfa seed growers in western North America who use populations of this bee for pollination. Basic studies were conducted to determine the etiology of this disease and the course of...

Mechanisms of orientation in the leaf-cutter bee Megachile rotundata (Fabricius)

Creator:: Osgood, Charles Edgar
Abstract:: The leaf- cutter bee Megachile rotundata (Fabricius) is an important alfalfa pollinator in western North America. This study was designed to provide information on methods of orientation used by M. rotundata in order to make recommendations regarding the parameters within which adult nesting populations may be relocated. Preliminary studies suggest...

The parasite Aspergillus flavus Link and other fungi of the biosphere of the alkali bee Nomia melanderi Ckll., in eastern Oregon and Washington

Creator:: Baker, Gerald Merritt
Abstract:: The pathogenicity of A. flavus on alkali bee larvae was studied using sample materials from three nesting sites of these soil inhabiting bees along the Oregon-Washington state line. Soil saprophytes of the biosphere of the alkali bee were also studied. Field observations and direction of soil cores from bee beds...

Some factors that affect pollination and seed formation in alfalfa, Medicago sativa L

Creator:: Bradner, Norman Richard
Abstract:: The objectives of this study were (a) to measure the amount of cross-pollination caused by three bee species at 10, 20 and 40 rods distance from a foreign pollen source, (b) to measure the effects of bee species, planting pattern and season on broad sense heritability estimates for seed yield...

Branching random walk and probability problems from physics and biology

Creator:: Johnson, Torrey
Abstract:: This thesis studies connections between disorder type in tree polymers and the branching random walk and presents an application to swarm site-selection. Chapter two extends results on tree polymers in the infinite volume limit to critical strong disorder. Almost sure (a.s.) convergence in the infinite volume limit is obtained for...

Native Bee and Spider Community Responses to Grassland Restoration and Wildfire

Creator:: Smith DiCarlo, Lauren A.
Abstract:: Up to 99.9% of native North American grasslands have been degraded since European settlement, primarily due to agricultural conversion. Today, grasslands are a top priority for restoration as they provide essential habitat for many rare and endangered species; however, the majority of studies in grasslands have focused on vegetation or...
