Life history patterns of two allopatric clupeids : Atlantic menhaden (Brevoortia tyrannus) and gulf menhaden (B. patronus)

Creator:: Powell, Allyn B.
Abstract:: Atlantic menhaden, compared to gulf menhaden, exhibit a life history pattern that appears to be adapted to a more unpredictable reproductive environment. From experiments on laboratory-reared eggs and larvae, Atlantic menhaden have larger eggs with larger yolk volume. They are larger at hatching, utilize their yolk faster, begin feeding at...

Planktivorous Auklets (Aethia pusilla and A. cristatella) nesting on St. Lawrence Island, Alaska as indicators of marine conditions in the northern Bering Sea

Creator:: Gall, Adrian
Abstract:: Monitoring reproductive success, prey species composition, and colony size of marine birds has been proposed as a method of assessing changes in marine systems that are otherwise difficult to sample (Cairns 1987). I measured inter-annual and intra-seasonal variability in reproductive parameters, taxonomic composition of the diet, and adult body condition...

Life history strategies and tactics of striped bass (Morone saxatilis) Walbaum

Creator:: Eldridge, Maxwell B.
Abstract:: Traditional approaches to research and management of striped bass have tended to be mechanistic, numerically oriented, and based on limited life history information. In the study presented here, comprehensive conceptual perspective was used in a multivariate study of life history and evolutionary adaptation of 10 striped bass populations representing the...

Population ecology of the Columbian white-tailed deer

Creator:: Gavin, Thomas Alan
Abstract:: A population of Columbian white-tailed deer (CWTD) was studied on a refuge (790 ha) in southwestern Washington during 1972-77. Quality of habitat was considered good for these deer and total population size remained between 164-230 as determined by mark-recapture methods during November. Population size declined significantly between the winters of...

A preliminary investigation of the spotted owl in Oregon

Creator:: Forsman, Eric D.
Abstract:: Between 1970 and 1974, data were collected on the distribution and biology of the spotted owl (Strix occidentalis) in Oregon. One-hundred and sixteen pairs and seven single birds were located. Spotted owls occurred throughout the mountains of western Oregon and on the east slope of the Cascade Range at least...

Distribution patterns of black-tailed deer (Odocoileus hemionus columbianus) in relation to environment

Creator:: Miller, Frank L.
Abstract:: Direct observation of a known number of black-tailed deer (Odocoileus hemionus columbianus), within the Cedar Creek study enclosure in the Tillamook Burn, Oregon, was carried on throughout 1964. Observations were made from three huts located outside of the enclosure on surrounding prominences. During this period, 1,410 hours of observational time...

The effects of irrigation water withdrawals on macroinvertebrate community structure and life history strategies

Creator:: Miller, Scott W.
Abstract:: I used current water management practices in central and eastern Oregon and Washington as natural experiments to quantify the effects of irrigation water withdrawals on macroinvertebrate community structure and life history strategies. Reduced discharge had direct (e.g. decreased velocity and wetted habitat) and indirect (e.g. increased conductivity and temperature) effects...

Productivity and nesting habitat of Great Basin Canada geese : Umatilla National Wildlife Refuge

Creator:: McCabe, Thomas R.
Abstract:: Great Basin Canada goose (Branta canadensis moffitti) productivity and nesting habitat utilization were studied on the Columbia River within the boundaries of the Umatilla National Wildlife Refuge during the springs of 1974 and 1975. Five islands, BL-1, BL-2, SD-1, SD-2, and Telegraph Island (TI), contained 88 percent of the nesting...

A comparison of early marine residence in hatchery and natural Chinook salmon (Oncorhynchus tshawytscha)

Creator:: Claiborne, Andrew M.
Abstract:: The mechanisms of mortality during critical life stages of fish are not well-understood and, for many species, it is not clear if the mechanisms are similar for naturally and artificially propagated individuals. For Chinook salmon (Oncorhynchus tshawytscha), natural fish potentially face negative interactions, such as competition, and survival disadvantages, such...
