Early succession in beds of the red alga, Iridaea cornucopiae Post. & Rupr. (Gigartinaceae) : alternate pathways

Creator:: Olson, Annette M.
Abstract:: Multiple successional sequences have been observed following disturbance in communities on marine hard substrata. Observations of the turf-forming alga, Iridaea cornucopiae Post. & Rupr. (Gigartinaceae), suggest that I. cornucopiae may assume its dominance by its ability to vegetatively pre-empt space. High limpet densities in the natural community, suggest that I....

The ecological and behavioral dynamics of breeding in three sympatric anuran amphibians

Creator:: Olson, Deanna H.
Abstract:: Breeding ecology and behavior were investigated in a field study of three sympatric anuran amphibians in the Oregon Cascade Mountains: the western toad (Bufo boreas), the Cascades frog (Rana cascadae) and the Pacific treefrog (Hyla regilla). A comprehensive study of the western toad mating system was conducted at three populations...

Carbon storage in a Pacific Northwest conifer forest ecosystem : a chronosequence approach

Creator:: Janisch, Jack E.
Abstract:: As concern over global warming intensifies, sequestration and storage of atmospheric CO2 has become an important scientific and policy issue. Confusion persists, however, over interpretation of forest carbon (C) source-sink dynamics, in part because conclusions drawn depend on temporal and spatial scales of analysis (e.g. day-week scale vs. successional-scale), type...

Nest-site selection in cooperatively breeding Pohnpei Micronesian Kingfishers (Halcyon cinnamomina reichenbachii) : does nest-site abundance limit reproductive opportunities?

Creator:: Kesler, Dylan C.
Abstract:: Despite their inherent importance and utility as ecological examples, island species are among the most endangered and least studied groups. Guam Micronesian Kingfishers (Halcyon cinnamomina cinnamomina) exemplify the plight of insular biota as a critically endangered and understudied island bird that went extinct in the wild before they could be...

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...

Delineating pattern and process in tropical lowland : mealy parrot migration dynamics as a guide for regional conservation planning

Creator:: Bjork, Robin D.
Abstract:: Most reserves fail to capture the habitat heterogeneity necessary to maintain viable populations of wide-ranging species. Methods to determine defensible dimensions of reserves and reserve networks are needed. The primary goal of this study was to develop such methods for lowland tropical forests by examining habitat- and spatial-use patterns of...

Spatial structure of the physical and biological distributions across the Antarctic Polar Front in austral spring and summer

Creator:: Howard, Cidney
Abstract:: Mesoscale surveys to examine the relationship between the physical processes and biological response along the Antarctic Polar Front (PF) were conducted as part of the US JGOFS Southern Ocean Program during austral spring and summer 1997/98. Multiple crossings of the PF near 170° W, using a towed undulating instrument, provided...

Ecology of populations of Van Dyke's salamanders in the Cascade Range of Washington State

Creator:: McIntyre, Aimee P.
Abstract:: The Van Dyke's salamander (Plethodon vandyke,) is a rare species endemic to Washington State. It has been found in cool moist microhabitats along streams, splash zones of waterfalls, and headwater seeps. We explored the association of the Van Dyke's salamander with hydrologic condition, geomorphology, disturbance characteristics, and vegetation structure in...

Bottom-up and top-down forces in tidepools : the influence of nutrients, herbivores, and wave exposure on community structure

Creator:: Nielsen, Karina Johanna
Abstract:: The relationship between nutrients and community structure is poorly understood in open-coast habitats. I created a system of artificial tidepools, of identical age and physical dimensions, at two sites that differed in wave exposure, and manipulated nutrient levels and the abundance of herbivores. Using these unique field mesocosms, I explored...

A market oriented approach to energy conservation identifying disadvantaged families as target groups for energy assistance programs

Creator:: Marganus, Martin
Abstract:: Energy expenditures, perceived family well being, and energy conservation actions were analyzed by family composition and level of income. Data were from a three state subsample (Arizona, Colorado, and Oregon; N = 2,633) of a larger stratified random sample of households in the Western United States. Data were collected in...

Macroscale to local scale variation in rocky intertidal community structure and dynamics in relation to coastal upwelling

Creator:: Freidenburg, Tess L.
Abstract:: Understanding how large-scale processes (>100 kms) influence ecological communities is currently a major focus in ecology. In marine systems, coastal upwelling, a large-scale oceanographic process in which surface water pushed offshore by winds is replaced by cold, nutrient-rich water from depth, appears to cause variation in rocky intertidal communities. Along...

Population genetics, ecology and evolution of a vertebrate metacommunity

Creator:: Manier, Mollie Kim
Abstract:: Population genetic structure is widespread in many organisms and can be found at small spatial scales. Fine-scale differentiation is the result of ecological and evolutionary processes working together to produce an overall pattern, but the relative importance of these factors in population differentiation is poorly understood. The goals of my...

Characterization of biochemical, functional properties, and market potential of Pacific whiting fish sauce

Abstract:: Biochemical properties, functional properties, and market potential of Pacific whiting (PW) fish sauce were investigated. Biochemical properties of fish sauce made from whole fish (W) and a mixture (1:1) of whole fish and surimi byproducts (WB) were compared. Market potential was evaluated through phone interviews and consumer panelists. Proteolysis was...
