Vegetation-environmental relationships on two clearcuts on the western slopes of the Oregon Cascades

Creator:: Egeland, Dawn M.
Abstract:: Douglas-fir and western hemlock growth and stocking were examined on two neighboring clear-cut watersheds in the Western Cascades of Oregon and related to the intensity of burning and logging disturbance, habitat type, soil type, aspect and the influence of percent cover of both invading Ceanothus species and residual Acer circinatum....

The development and application of benthic classifications for coral reef ecosystems below 30 m depth using multibeam bathymetry : Tutuila, American Samoa

Creator:: Lundblad, Emily Ruth
Abstract:: Coral reef ecosystems are the most diverse on earth, and their subsistence is being threatened by natural and adverse anthropogenic patterns and processes. In an effort to understand and protect these marine environments, several programs have outlined strategies and initiatives. For example, the United States Coral Reef Task Force’s Mapping...

Geographic information systems for coral reef conservation, capacity building, and public education in American Samoa

Creator:: Larkin, Emily M.
Abstract:: Coral reefs around the world face numerous threats, both natural and anthropogenic, including pollution, natural disasters, invasive species, habitat destruction, and destructive methods of fishing. Given enough time, coral can recover from natural disasters, but anthropogenic threats decrease corals’ ability to recover from things such as hurricanes. It is difficult...

Integration of submersible transect data andhigh-resolution sonar imagery for a habitat-based groundfish assessment of Heceta Bank, Oregon

Creator:: Nasby, Nicole M.
Abstract:: Dramatic declines in several groundfish populations have occurred along the U.S. West Coast during the last decade (PFMC 1999, Sampson 1997, Ralston 1998, Bloeser 1999). One problem exacerbating these declines is insufficient stock assessments, especially for species of west coast rockfish (Family Scorpaenidae, Genus Sebastes) which comprise the core of...

Assessment of the potential for conflict between existing ocean space use and renewable energy development off the coast of Oregon

Creator:: Sullivan, Colleen M.
Abstract:: Oregon's ocean waters are a potential source of wind, wave, and tidal energy; of interest to renewable energy entrepreneurs and to the U.S. government as it seeks to bolster energy security. In order to install technology to capture this energy, however, it may be necessary to mitigate conflict with existing...

GIS modeling of potential marine protected areas in the Northwest Atlantic via biological and socioeconomic parameters

Creator:: Keith, Charles M.
Abstract:: Overfishing of our national marine resources has degraded some of the most productive fishing regions in the Northwest Atlantic Ocean, most notably the Gulf of Maine and Georges Bank. These regions may have shifted from productive trophic regimes to a less than optimal state therefore reducing fishers’ catches and associated...

Distribution and habitat associations of the northern pygmy-owl in Oregon

Creator:: Sater, Dawn M.
Abstract:: I conducted acoustic lure surveys of northern pygmy-owls (Glaucidium gnoma) on transects that were systematically placed in forested areas throughout the state of Oregon. My objectives were to determine if pygmy-owls were associated with particular forest types, ecoregions, or with large-diameter dominant overstory trees. I also examined temporal variation in...

Breeding season habitat use and response to management activities by greater sage-grouse on Sheldon National Wildlife Refuge, Nevada

Creator:: Davis, Dawn M.
Abstract:: Greater Sage-Grouse (Centrocercus urophasianus) have experienced declines throughout their range over the last 50 years. Long-term declines in sage-grouse abundance in Nevada and Oregon have been attributed to reduced productivity. From 1995-1997, sage-grouse production on Sheldon National Wildlife Refuge (SNWR), Nevada was greater compared to Hart Mountain National Antelope Refuge...

An Investigation into the Distribution, Residency Patterns, Population Connectivity, and Abundance of Blue Whales (Balaenoptera musculus) in New Zealand

Creator:: Barlow, Dawn R.
Abstract:: Species conservation depends on robust population assessment. Data on population abundance, distribution, and connectivity are critical for effective management, especially as baseline information for newly documented populations. I describe a pygmy blue whale (Balaenoptera musculus brevicauda) population in New Zealand waters with year-round presence that overlaps with industrial activities. This...

Exploring Alternative Approaches for Native Plant Production and Ecological Restoration in the Pacific Northwest

Creator:: Placido, Wilman M.
Abstract:: Global recognition of the need for ecosystem restoration and revegetation following natural and anthropogenic disturbances has been growing in recent years. Successful programs often depend on the use of nursery-grown seedlings and appropriate mitigation of limiting factors on outplanting sites. Nursery production of high-quality native plants for restoration can be...
