Photo-identification of Melon-headed Whales (Peponocephala electra) in the Marquesas Islands : Creation of the First Photo-identification Catalog and Estimation of Group Size and Minimum Abundance in a Remote Archipelago

Creator:: McClung, John Ralph, II
Abstract:: For many species of oceanic dolphins, photo-identification and genetic data indicate that these island-associated populations are demographically isolated from pelagic populations and that island-associated populations exhibit very different patterns of movement and habitat use. Melon-headed whales (Peponocephala electra) are generally considered a pelagic dolphin, but have been documented around oceanic...

The migratory pattern of audlt sockeye salmon (Oncorhynchus nerka) in Bristol Bay as related to the distribution of their home-river waters

Creator:: Straty, Richard R.
Abstract:: The individual stocks of sockeye salmon that make up the annual spawning migration to the Bristol Bay region of Western Alaska are produced in the lakes and streams of ten major river systems, which discharge into the bay over a shoreline distance of 120 miles. The hypothesis adopted in this...

The effects of dietary algal and lipid supplements on the gonadal and larval development of Crassostrea gigas kumamoto (Thunberg)

Creator:: Robinson, Anja M.
Abstract:: Under laboratory conditions, elevated temperatures accelerated production of gametes. However, when conditioning for spawning at elevated temperatures was initiated early in the season (January-March), larval survival and number of spat collected were significantly lower than when conditioning was initiated in may or June. At elevated temperatures, broodstock oysters were fed...

Biodiversity in managed forests of western Oregon : species assemblages in leave islands, thinned, and unthinned forests

Creator:: Wessell, Stephanie J.
Abstract:: Both leave islands, or green tree retention clusters, and thinning prescriptions have been proposed as alternative silvicultural strategies designed to sustain the structural and biological diversity of managed forests. However, the relationship of the physical structure of leave islands and thinned forests to their associated microclimates, flora, and fauna remain...

Vegetation response to prescribed fire in mountain big sagebrush ecosystems at Lava Beds National Monument, California

Creator:: Ellsworth, Lisa M.
Abstract:: Anthropogenic land use alterations such as livestock grazing and fire suppression have greatly altered sagebrush grasslands of the Great Basin, facilitating invasion of exotic annuals, increases in woody species, and losses of native species. Much of the current research surrounding wildland and prescribed fire in sagebrush dominated ecosystems has focused...

A genetic study of the red-band trout (Salmo sp.)

Creator:: Wilmot, Richard L.
Abstract:: A group of trout that reside in streams of the desiccating lake basins of southeastern Oregon differ markedly from other known Salmo. Known commonly as the red-band trout, this fish was subjected to chromosome analysis for comparison with other species of western North American Salmo. The karyotype of the red-banded...

The chronic toxicity of 2,3,7,8-tetra-chlorodibenzo-p-dioxin (TCDD) to five selected aquatic organisms

Creator:: Miller, Richard A.
Abstract:: Five species of aquatic organisms were exposed to TCDD. Lethal effects of initial exposure to coho salmon of 23.4 nanogram TCDD/gram fish wet weight (23.4 ng/g), or equivalent to 100 nanogram per liter (100 ng/l) TCDD in water, for 24 hours were irreversible; 95% mortality occurred in 60 days. Exposure...

Humpback whales (Megaptera novaeangliae) in the South Pacific breeding grounds : an allocation from feeding areas and an abundance estimate of whales specific to French Polynesia waters

Creator:: Gibb, Giselle Renee
Abstract:: South Pacific humpback whales were devastated by commercial whaling in their Antarctic feeding areas during the 20th century. Understanding migratory connections and current abundance of these isolated breeding stocks is crucial for the allocation of historical Antarctic catches in population dynamic models used to assess current recovery. However, only a...

White-breasted nuthatch density and nesting ecology in oak woodlands of the Willamette Valley, Oregon

Creator:: Viste-Sparkman, Karen
Abstract:: Habitat loss causes a reduction in available resources for wildlife, alters the configuration of remaining habitat, and may isolate wildlife populations. White-breasted nuthatches (Sitta carolinensis) are experiencing long-term population declines in the Willamette Valley of Oregon, where they are historically associated with oak woodlands. As secondary cavity-nesters, white-breasted nuthatches may...
