Reproductive ecology and endocrinology of the garibaldi damselfish, Hypsypops rubicundus (Pomacentridae)

Creator:: Sikkel, Paul C.
Abstract:: I examined two aspects of the reproductive behavior of the garibaldi, Hypsypops rubicundus, a temperate marine damselfish with male parental care. My primary objective was to determine the relationship between female choice and male parental investment in the care of offspring. In particular, I sought to determine: (1) how the...

Habitat structure and occupancy patterns of the montane frog, Rana cascadae, in the Cascade Range, Oregon, at multiple scales : implications for population dynamics in patchy landscapes

Creator:: Brown, Catherine, 1958-
Abstract:: Associations between occupancy patterns of a montane anuran species, Rana cascadae, and habitat structure at multiple scales were examined to investigate how population structure may influence persistence in spatially and temporally heterogeneous environments. Predictions were based on population dynamics suggested by source-sink and metapopulation models. Potential sites in three basins...

Symbiotic characteristics of Rhizobium leguminosarum bv. trifolii recovered from nodules of field-grown Trifolium subterraneum L.

Creator:: Wanjagi, Francis Ndung'u
Abstract:: In a series of greenhouse experiments, isolates representing serotypically distinct subpopulations of Rhizobium leguminosarum bv. trifolii recovered from root nodules of field-grown subclover Trifolium subterraneum cv. "Nangeela"), were evaluated for their symbiotic effectiveness potential, their effect on regrowth potential of subclover, and for their competitive abilities to form nodules. Isolates...

Symbiotic and saprophytic characteristics of a soil population of Rhizobium leguminosarum bv. trifolii

Creator:: Yap, Kathryn H. M.
Abstract:: Although much has been learned about the comparative nodulating behavior of simple mixtures of rhizobial strains under non-soil situations, it is unclear how these findings relate to the factors influencing nodulation success by the complex mixtures of strains found within soil-borne rhizobial populations. Information on the structure and physiological behavior...

Characteristics of bradyrhizobium sp. recovered from Oregon soils

Creator:: Cheng, Hsin-hua
Abstract:: Although the biology of Bradyrhizobium has been studied for almost one hundred years, virtually nothing is known about the ecology and genetic variation in natural soil populations of this genus. The majority of information has been obtained from studies of one species, Bradyrhizobium japonicum, and the diversity within soil populations...

Correlation between structural heterogeneity and arthropod biodiversity : implications for management of Pacific Northwest forests

Creator:: Madson, Stephanie Lee
Abstract:: The "old-growth controversy" in the Pacific Northwest recognized thinning as the primary silvicultural practice for land managers to produce wildlife habitat while continuing to produce timber. For the foreseeable future, forest stands will be harvested to produce forest gaps and a patchwork of trees of different ages. In order to...

Pheromonal mediation of reproductive behavior in the brown tree snake

Creator:: Greene, Michael John
Abstract:: In animals, reproductive behaviors serve to attract individuals together during the breeding season and to coordinate the behavioral and physiological states of individuals so that mating can successfully occur. In snakes, the various reproductive behaviors including courtship, mating, courtship inhibition, male combat and trailing are mediated primarily by pheromones. Pheromones...
