Ecology of breeding mallards : nest parasitism; brood survival; and habitat utilization

Creator:

Talent, Larry Gene

Abstract:

In 1976 and 1977 I examined three broad problems associated with the recruitment of young mallards, Anas platyrhynchos, in the Prairie Pothole Region of North Dakota. The three problems studied were: the effects of interspecific nest parasitism on production; the chronology and magnitude of total-brood loss during the brood-rearing period;...

Trophic adaptations and relationships of rockfishes (Sebastes spp.) of Oregon

Creator:

Pequeño, Germán E.

Abstract:

A comparative analysis of structures related to capture and processing of food, in 624 specimens belonging to 31 species of Sebastes of Oregon was made. The structures studied were the following: the tooth-bearing bones (premaxillary, dentary, vomer, palatine); the maxillary, angular, articular, parasphenoid and glossohyal bones; the lower limb of...

Patterns in coastal marsh vegetation of the Juneau area, Alaska

Creator:

Stone, Catherine S.

Abstract:

A vegetation study was made of four coastal marshes near Juneau, Alaska. Results confirmed earlier studies' findings in southeast Alaska that communities or assemblages of species can be identified but from marsh to marsh these assemblages appear to have no consistent relationship to each other or to environmental "factors" such...

A model for understanding the influence of selective and nonselective harvest on fish populations

Creator:

Hirai, Takayuki

Abstract:

To understand the influence of selective harvesting on the adaptive capacity of fish populations in changing environments, a computer simulation model was developed. In the model, hypothetical populations were composed of five different life histories, which were genetically determined. Each life history type had its own rate of survival and...

Seasonal distribution and environment of adult Pacific herring (Clupea harengus pallasi) near Auke Bay, Lynn Canal, southeastern Alaska

Creator:

Carlson, Harry Richard

Abstract:

The distribution of adult Pacific herring (Clupea harengue pallasi) near Auke Bay, Lynn Canal, southeastern Alaska, varied by depth and geographic area over 24 successive months during 1973-75. From June through September, schools concentrated at 5- to 37-m depths where zooplankton was abundant, and moderate currents were present in a...

Stream habitat utilization and behavior of sympatric and allopatric wild cutthroat trout (Salmo clarki) and hatchery coho salmon (Oncorhynchus kitsutch)

Creator:

Jacobs, Steven Edward

Abstract:

The behavior and stream habitat utilization of juvenile hatchery-reared coho salmon (Ovicozihynchus kisutch) and wild cutthroat trout (Salmo clarki) were examined to assess the nature of interactions between the species potentially resulting from introductions of hatchery coho salmon in streams. Habitat utilization was monitored in Mill Creek, Polk Co., Oregon...

Elevated temperature and the production of juvenile Chinook salmon (Oncorhynchus tshawytscha) in a model stream

Creator:

Bisson, Peter Andre

Abstract:

Temperature was elevated approximately 4° C in a model stream relative to an unheated, but otherwise similar control stream. The streams were located outdoors, received identical amounts of exchange water from a nearby creek, and followed natural diurnal and seasonal temperature cycles Juvenile spring chinook salmon (Oncorhynchus tshawytscha) were introduced...
