Daily activity patterns, survival, and movements of red tree voles (Arborimus longicaudus) in western Oregon

Swingle, James Kerr (2005-11-29)
DDT and reproductive success of bluebirds and house wrens in Northeastern Oregon

McCluskey, D. Cal (1976-11-30)
Defining quantitative stream disturbance gradients and the additive role of habitat variation to explain macroinvertebrate taxa richness

Ligeiro, Raphael; Hughes, Robert M.; Kaufmann, Philip R.; Macedo, Diego R.; Firmiano, Kele R.; Ferreira, Wander R.; Oliveira, Deborah; Melo, Adriano S.; Callisto, Marcos (Elsevier, 2013-02)

Most studies dealing with the use of ecological indicators and other applied ecological research rely on some definition or concept of what constitutes least-, intermediate- and most-disturbed condition. Currently, most ...
Delayed mortality of hatchery-reared rainbow trout in relation to five chemical factors encountered in transporting waters

Linn, Devon Wayne (1955-05-05)
Density dependent relationships in trophic processes of simplified stream communities

Brocksen, Robert W (1969-01-21)
Density, sex ratio, and space use in the gray-tailed vole, Microtus canicaudus

Bond, Monica L. (1998-10-12)

Female and male mammals have different behavioral strategies for maximizing their reproductive success. Pregnancy and lactation obligate female mammals to provide greater parental investment than males; thus, females c ...
Detection of deforestation and land conversion and estimation of atmosperic emissions and elemental pool losses from biomass burning in Rondônia, Brazil

Guild, Liane S. (2000-02-24)

Biomass burning associated with deforestation and land use in the Amazon, greatly contributes to emissions as well as depletion of elemental pools. We identified deforestation and pasture formation and quantified resulta ...
Determination of marine migratory behavior and its relationship to selected physical traits for least cisco (Coregonus sardinella) of the western Arctic coastal plain, Alaska

Seigle, John C. (2003-12-19)

With increased resource development on the western Arctic coastal plain of Alaska (especially within the oil extraction industry) it is important to understand the basic life history attributes of whitefish stocks in t ...
Determination of molecular hydrocyanic acid in water and studies of the chemistry and toxicity to fish of metal-cyanide complexes

Broderius, Steven J. (1973-02-28)

A reliable, easy, and inexpensive method for determination of molecular hydrocyanic acid (HCN) in solutions of simple and complex metal cyanides is described. The method was used to determine molecular HCN concentrati ...
Determination of molecular hydrocyanic acid in water and studies of the chemistry and toxicity to fish of the nickelocyanide complex

Broderius, Steven J. (1969-08-08)
Development and application of steelhead (Oncorhynchus mykiss) kelt identification techniques

Evans, Allen F. (2003-03-14)
The development and evaluation of an audio-index technique for the band-tailed pigeon

Keppie, Daniel MacKenzie (1969-06-13)
Development of a rodent control program on a South Pacific military base

Long, Jay B. (1948-05)
Development of a streamside incubator for culture of Pacific salmon

Poon, Derek Clinton (1969-12-11)

Criteria for the design and construction of a prototype streamside incubator for Pacific salmon (Oncorhynchus) eggs and alevins are described. Operation of the prototype and methods of transporting freshly spawned sal ...
Development of artificial diets for delivery of water-soluble nutrients to altricial fish larvae

Onal, Umur (2002-11-26)

In the present study, the potential of low-melting point lipids, namely methyl palmitate (MP) and menhaden stearine (MS), were studied for delivery of water-soluble materials to fish larvae. Addition of the solid emul ...
Developmental rate: A unifying mechanism for sympatric divergence in postglacial fishes?

Mcphee, Megan V.; Noakes, David L. G.; Allendorf, Fred W. (Current Zoology, Institute of Zoology, Chinese Academy of Sciences, 2012)

Morphologically divergent ecotypes arise in fish populations on postglacial time scales, and resource polymorphisms are often invoked to explain their origin. However, genetic recombination can constrain the ability of ...
Diet and nutrition of female sage grouse during the pre-laying period

Barnett, Jenny K. (1992-09-04)

Nutrition effects productivity of grouse. Females that obtain high nutrient diets in spring produce larger clutches and larger, more viable chicks than hens on less nutritious diets. Grouse select high nutrient foods ...
Differences in pathogenicity and pathology of Vibrio anguillarum and Vibrio ordalii in chum salmon (Oncorhynchus keta) and English sole (Parophrys vetulus) under laboratory conditions

Handoyo, Nitimulyo Kamiso (1985-08-12)
A Dimensionless Invariant for Relative Size at Sex Change in Animals: Explanation and Implications

Gardner, Andy; Allsop, David J.; Charnov, Eric L.; West, Stuart A. (University of Chicago Press, 2005-05)

Recent comparative studies across sex-changing animals have found that the relative size and age at sex change are strikingly invariant. In particular, 91%–97% of the variation in size at sex change across species can ...
Direct and indirect effects of livestock grazing intensity on processes regulating grassland bird populations

Johnson, Tracey N. (2011-01-19)

In grasslands, grazing by large ungulates can influence vegetation structure, composition, primary productivity, and ultimately, ecosystem functioning. While grazing represents a complex disturbance, grazing intensity la ...
