Drought, dispersal, and community dynamics in arid-land streams

Creator:: Bogan, Michael T.
Abstract:: Understanding the mechanisms that regulate local species diversity and community structure is a perennial goal of ecology. Local community structure can be viewed as the result of numerous local and regional processes; these processes act as filters that reduce the regional species pool down to the observed local community. In...

Aquatic insect adaptations to different flow regimes

Creator:: Yamamuro, Asako Melody
Abstract:: My thesis explored the effects of environmental variability on population dynamics and community composition of aquatic insects. Environmental variability in the form of flow regime in streams can limit the distribution and life-history traits of aquatic insects. I used tributaries to the McKenzie River in Oregon with dramatically different flow...

The habitat requirements and ecological relationships of Microtus oregoni (Bachman), Microtus townsendii (Bachman), and Microtus montanus (Peale) in Benton County, Oregon

Creator:: Goertz, John William
Abstract:: The object of this research is to ascertain the habitat occupied by each of the three species of voles of the genus Microtus found living in Northern Benton County, Oregon.

A comparative analysis of morphological, physiological, and biochemical adaptation to abiotic stress in intertidal porcelain crabs, genus Petrolisthes

Creator:: Stillman, Jonathon Harris
Abstract:: Organismal tolerance to abiotic environmental stresses contributes significantly to setting the distribution limits of organisms, as demonstrated by vertical zonation patterns in the marine intertidal zone. In this thesis, the ultimate (evolutionary) and proximate (mechanistic) causes of tolerance to temperature and emersion stresses associated with the intertidal zone were examined...

The fine structure of spermatid differentiation in the mussel, Mytilus edulis, Linn

Creator:: Longo, Frank J., 1939-
Abstract:: The spermiogenesis of Mytilus edulis (a marine mussel) has been studied, employing techniques of light and electron microscopy and cytochemical preparations. The observations trace the development of the acrosomal complex, the nucleus, the mitochondrial middle-piece, and the flagellum. In early spermatids numerous membrane-bounded proacrosomal vesicles arise from several Golgi complexes...

Succession and stability in two rocky intertidal communities on the central Oregon coast

Creator:: Farrell, Terence M.
Abstract:: The stability of a limpet-dominated community was assessed in a experiment in which an consumer was temporarily removed. Compared to unmanipulated plots, the limpet-exclusion plots developed greater algal abundance and altered species composition of both algae and barnacles. The community was not perturbed beyond its capacity to recover, since the...

Small mammal micro- and macrohabitat selection in streamside ecosystems

Creator:: Doyle, Arlene T.
Abstract:: During summer and fall of 1981 to 1983, mark-recapture was conducted in riparian and upland habitats within old-growth and mature forests in the Cascade Range of Oregon. Number of individuals and species richness were greater in riparian than upland habitat. For most species, the mean adult weights and the percentages...
