The roles of provenance and phylogeny in recruitment, community assembly, and species coexistence in invaded California grasslands

Creator:: Brandt, Angela J.
Abstract:: Biological invasions pose one of the greatest threats to global biodiversity, but many naturalized invaders coexist with the native community. Community ecology theory provides a framework for understanding the mechanisms by which invaders might coexist with native species or exclude them from the community, thus informing management practices to maximize...

The incidence and development of somatic polyploidy in the marine isopod Idothea wosnesenskii

Creator:: Matlock, Daniel Budd
Abstract:: (Brandt) were surveyed for the presence of polyploid cells. Large polyploid cells were found in the hepatic cecum, gut and sheath of the testis. The relative DNA content of the polyploid nuclei was measured by means of two wavelength cytophotometry. Histograms plotted from the data provide information on the level...

Resource allocation in four syntopic species of marine diving birds

Creator:: Scott, James Michael, 1941-
Abstract:: During 1969-1971 I studied patterns of resource allocation and behavioral interaction among Brandt's Cormorants, Pelagic Cormorants, Common Murres and Pigeon Guillemots in the area of a breeding colony on Yaquina Head on the central Oregon coast. Extensive studies of the breeding colony were combined with detailed observations of the distribution,...

Chemical cues and the molecular basis of olfactory chemoreception in caudate amphibians

Creator:: Kiemnec, Karen M.
Abstract:: Chemoreception is one of the dominant sensory modalities for many species of salamanders (reviewed in Chapter 2). At least seven of the ten currently recognized salamander families are known to respond to some sort of chemical cue. These responses are as varied as delaying hatching, seeking refuge, or initiating aggressive...

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...

Effects of environmental stress on intertidal mussel reproduction

Creator:: Petes, Laura E.
Abstract:: Environmental stress can negatively affect the ability of organisms to reproduce. Energetic trade-offs exist in all organisms, and under stress, energy may be allocated away from reproduction and towards physiological defense and repair mechanisms. The rocky intertidal environment is ideal for investigating the influence of environmental stress, as organisms are...

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...

Larval dispersal in marine fishes: novel methods reveal patterns of self-recruitment and population connectivity

Creator:: Christie, Mark R.
Abstract:: Many marine fish populations are severely declining due to over-fishing, loss of both juvenile and adult habitats, and accelerating environmental degradation. Fisheries management and the implementation of marine protected areas (MPAs) and other conservation tools are currently hindered by large gaps in knowledge about larval dispersal and its subsequent effects...

Adaptive diversity and divergence at frog antimicrobial peptide loci

Creator:: Tennessen, Jacob A.
Abstract:: In this dissertation I study evolutionary patterns at genes encoding antimicrobial peptides (AMPs) in frogs. AMPs are short, amphipathic, cationic, secreted proteins that kill bacteria and other pathogens through a non-catalytic mechanism that involves binding to and disrupting the microbial cell membrane. In many animal taxa, positive selection is much...
