Bird and rodent nesting in excavated cavities in Pinon-juniper woodland, southeastern Colorado

Creator:: Youkey, Donald E.
Abstract:: I studied bird and rodent nesting in woodpecker-excavated cavities in pifion-juniper (Pinus edulis-Juniperus monosperma) (P-J) woodland in southeastern Colorado during the spring and summer of 1987 and 1988. Two related investigations were conducted: one described characteristics of habitat used by birds and rodents nesting in woodpecker-excavated cavities and the other...

Changes in size and age at maturity of Columbia River upriver bright fall chinook salmon (Oncorhynchus tshawytscha) : implications for stock fitness, commercial value, and management

Creator:: Beaty, Roy E.
Abstract:: The average size and age of chinook salmon (Oncorhynchus tshawytscha) caught in commercial fisheries along the Pacific Coast of North America have decreased substantially in this century. These declines might be caused in part by changes in size and age at maturity within the stocks contributing to those fisheries. Upriver...

Resource Type:: Dissertation

Ecology of mallard ducklings on Lower Klamath National Wildlife Refuge, California

Creator:: Mauser, David M.
Abstract:: The ecology of female mallards (Anas platyrhynchos) and their broods was studied during 1988-90 on Lower Klamath National Wildlife Refuge, California. Survival of 127 radio-marked ducklings from 64 broods was 0.18 to 10 days of life, and 0.37 and 0.34 to fledging for 1988, 1989, and 1990, respectively. For the...

The disposition of four therapeutically important antimicrobial agents in llamas

Creator:: Murdande, Sharad B.
Abstract:: The disposition of four therapeutically important antimicrobial agents was studied in llamas following intravenous bolus administration. Six llamas were each given ampicillin, tobramycin, trimethoprim and enrofloxacin at a dose of 12 mg/kg, 1 mg/kg, 3 mg/kg and 5 mg/kg of body weight with a wash out period of 3 days...

The use of logistic regression for developing habitat association models

Creator:: Sjamsoe'oed, Roza
Abstract:: Quantitative habitat models of wildlife-habitat relationships are developed to formalize our current understanding about an ecological system. A habitat association model is one of these models that is useful for answering questions about how the habitat is occupied, how much growth habitat is required by the animal, or how the...

Wheat genotypes selected under optimum conditions and their response to water and heat stress

Creator:: Briceno-Felix, Guillermo Ariel
Abstract:: Concerns have been expressed that wheat (Triticum aestivum L.) cultivars selected under optimum conditions may lack adequate adaptation for stress environments. Experimental populations were grown under three environmental conditions 1) optimum, 2) reduced irrigation, and 3) high temperature. Field experiments were conducted at the Center for Northwest Experimental Station (CIANO),...

A comparison of nest site selection and reproductive effort by reticulate sculpin (Cottus perplexus) in two streams of different geologies in the central Coast Range of Oregon

Creator:: Bateman, Douglas S.
Abstract:: Nest sites of reticulate sculpin (Cottus perplexus) were located in two stream reaches, one from a basalt basin and one from a sandstone basin. Stream reaches were similar in gradient, basin area, elevation, climate, and riparian vegetation but differed in biologic community structure and substrate characteristics. An electivity index was...

Gas chromatography/olfactometry and descriptive analysis of cold-pressed lemon oil aroma

Creator:: Young, Sheri L.
Abstract:: Lemon oil quality is affected by numerous factors including lemon variety, climate, soil type, extraction method, etc.. Therefore, quality largely depends upon the lemons' origin, and aroma profiles of oils obtained throughout the world have potential to vary considerably. This research was conducted to identify differences in the aroma profiles...

Instrumental and sensory texture profile analysis of Asian wheat noodles

Creator:: Pipatsattayanuwong, Siriporn
Abstract:: Texture, a critical property of Asian wheat noodles, is normally assessed by sensory evaluation. However, sensory evaluation may be impractical for wheat breeders and noodle researchers who need to evaluate a large number of samples and have limited sample. Instrumental Texture Profile Analysis (TPA) has been widely employed to evaluate...
