Delivering oxytetracycline to first-feeding zebrafish Danio rerio (Hamilton) and goby Asterropteryx semipunctata (Rüppell) larvae using lipid spray beads

Creator:: Temple, Ephraim E.
Abstract:: Effective treatment of larval bacterial diseases is a difficult problem when culturing ornamental fish. Oral administration of antibiotics using existing microparticle types is not effective due to high leakage rates; furthermore, injection of larvae is not practical. Treatment is currently limited to use of antibiotic baths, . In this study,...

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...

Reproduction in the eastern cottontail rabbit in Oregon

Creator:: Trethewey, Donald Edwin
Abstract:: Reproductive characteristics of introduced eastern cottontail rabbits, Sylvilagus floridanus (J. A. Allen), were determined from 486 rabbits collected between January 1, 1968 and June 30, 1969, near Corvallis, Oregon. Sex ratios were 1:1 for all rabbits collected and for all embryos 20 days or more gestation. On the basis of...

The reproductive biology of the mountain cottontail rabbit in Oregon

Creator:: Powers, Roger Alan
Abstract:: The reproductive characteristics of the mountain cottontail rabbit, Sylvilagus nuttalli (Bachman), were investigated from 269 specimens collected in central Oregon between 28 May 1968 and 28 August 1969. Male rabbits were in breeding condition between mid-February and 3 July 1969. Nearly 77% of the females bore four litters between 7...

Spatial Variation in Ecosystem Carbon Stocks and Emissions Resulting from Land-use Conversion: Two Studies in Mangrove Forests of the Dominican Republic

Creator:: Giovannoni, Leila R.
Abstract:: Mangrove forests store more organic carbon across ecosystem carbon pools than most other coastal and forested ecosystems, and are subject to high global rates of deforestation. For these reasons, they are recognized as prime candidates for inclusion in climate change mitigation strategies. However, the ecological drivers of regional and micro-scale...

Morphological changes in introduced eastern cottontails in Oregon

Creator:: Rhodes, Mark Nicolas
Abstract:: Descendants of eastern cottontails from Ohio (Sylvilagns floridanus) introduced in Benton County, Oregon and cottontails from Ohio were sampled and analyzed morphometrically and colorimetrically. In general, Oregon cottontails were smaller and lighter in color than Ohio rabbits. Introgression and interspecific competition with the smaller and darker colored native brush rabbit...

Influence of water hardness on gill accumulation and acute toxicity of aluminum in rainbow trout

Creator:: Bustaman, Sjahrul
Abstract:: Rainbow trout were exposed to aluminum at pH 7.25 and 8.25 and four hardnesses (10, 30, 80, and 120 ppm CaCO₃) for 96 hours in a continuous-flow system and mortality and aluminum accumulation in the gills were determined. Temperature, pH, and dissolved oxygen were measured daily for each treatment. Dissolved...

Estimation of Population Age Structure, Detection Probability, and Density of Red Tree Voles in Oregon

Creator:: Marks-Fife, Chad A.
Abstract:: Red tree voles (Arborimus longicaudus) are a unique species of Arvicoline rodent found in western Oregon and northwest California. Their preferred habitat is mature and old-growth coniferous forest dominated by Douglas-fir (Pseudotsuga menziesii). Tree voles are an important prey item for northern spotted owls and many other predators, but are...

The effects of acclimation and surface access on the resistance of fish to hypoxic stress

Creator:: Wirosoebroto-Hartadi, Retno Widaningroem
Abstract:: Rainbow trout (Salmo gairdneri) and bluegill (Lepomis macrochirus) were exposed to flows of water containing low DO concentrations produced by bubbling nitrogen through the water. Abrupt exposure of fish to critical DO concentrations (The standard dose response) and by a more gradual changing of DO levels (The "stepdown" approach) were...
