Architecture, size, and reproduction in plants : a pollination study of Mertensia ciliata (James) G. Don

Creator:: Geber, Monica
Abstract:: I experimentally test the hypothesis that the potential for selfing increases with plant size in Mertensia ciliata (Boraginaceae), a self-compatible, profusely-flowering perennial. This follows from the premises that 1) pollen dispersal by pollinators between flowers is limited, and 2) individual pollinators, in this study bumblebees, will visit more flowers per...

William Ernest Castle, American geneticist : a case-study in the impact of the Mendelian research program

Creator:: Taylor, H. Terry
Abstract:: In their modern context questions of heredity have come to be closely aligned with theories of evolution because all such theories require the presence of heritable variation. Thus the need for an understanding of a source of variation and a mechanism for its inheritance became very apparent with the general...

Population dynamics of the cinnabar moth, Tyria jacobaeae (Lepidoptera: Arctiidae)

Creator:: Isaacson, Dennis
Abstract:: The dynamics of a field population of the cinnabar moth, Tyria jacobaeae L., were studied near Jordan, Linn County, Oregon. In both 1970 and 1971 larval populations were so large that all foliage of the host weed, tansy ragwort, Senecio jacobaea L., was consumed. The ensuing starvation accounted for the...

Metabolic adaptations of the marine gastropod Thais emarginata

Creator:: Sweat, Sister Jean
Abstract:: Thais emarginata is a gastropod which inhabits the midlittoral zone of the intertidal region. Oxygen consumption of high-level and low-level organisms was determined at various seasons of the year over an experimental temperature range of 5 to 20° C. No significant difference in respiratory rate between separate populations of high-level...

Experimental taxonomy, 1930-1950 : the impact of cytology, ecology, and genetics on ideas of biological classification

Creator:: Hagen, Joel Bartholemew
Abstract:: During the years between 1930 and 1950 a number of attempts were made to introduce techniques and ideas from cytology, ecology, and genetics into the field of taxonomy. Advocates of this "experimental taxonomy" believed that cytological, ecological, and genetic techniques would provide a rigorous, objective methodology to replace the traditional...

Population and community ecology of the red alga Rhodomela larix (Turner) C. Agardh, on the central Oregon coast

Creator:: D'Antonio, Carla Marie, 1956-
Abstract:: Aspects of the life history and ecology of the intertidal turf-forming alga Rhodomela larix (Turner) C. Agardh were examined over a two year period at several sites on the Oregon coast. Rhodomela occurred over a broad tidal range and exhibited different growth and morphology characteristics with respect to tidal height....

Influence of host anemia on blood-feeding rate and egg production of Aedes aegypti (L.) (Diptera : Culicidae)

Creator:: Shieh, Jong-Neng
Abstract:: I tested a theoretical model proposing that anemia favors transmission of blood-borne parasites to vectors by accelerating the blood-feeding rate. Using Aedes aegypti, the yellow fever mosquito, initially, I was not able to confirm this phenomenon either in an artificial or a live system; anemia did not correlate with blood-feeding...

Ecological aspects of kin discriminating behavior with implications of functional value

Creator:: Hokit, D. Grant
Abstract:: To assess the context dependence of kin discriminating behavior, I examined kin-biased aggregation behavior in tadpoles of R. cascadae in different ecological conditions. I manipulated food distribution, predator presence, thermal heterogeneity, and relatedness in a multifactorial mesocosm experiment. All four factors interacted to influence tadpole dispersion. My results suggest that...
