The effects of the herbicides Diquat and Dichlobenil on pond invertebrates

Creator:: Wilson, Dennis Carl
Abstract:: The acute toxicity of Diquat (1:1-ethylene-2:2' dipyridylium dibromide) and Dichlobenil (2, 6-dichlorobenzonitrile) to six selected pond invertebrates was determined using the median tolerance limit estimation method. Diquat was more toxic to the amphipod, Hyalella azeteca than to the aquatic insects Callibaetis, Limnephilus, Enallagma, Libellula, and Tendipedidae. The addition of mud...

The effects of rotational grazing and prescribed burning on bobwhite populations in south Texas

Creator:: Wilson, Marcia H.
Abstract:: Short-term effects of 3 grazing systems and prescribed burning on bobwhite (Colinus virginianus) populations were investigated on the Welder Wildlife Refuge near Corpus Christi, Texas, during spring (April through June) and fall (September through October) of 1976 and 1977. Two rotational systems, high intensity-low frequency (HILF) and four-pasture, deferred-rotation (4PDR),...

The effects of different otolith ageing techniques on estimates of growth and mortality for two species of rockfishes, Sebastes pinniger and Sebastes diploproa

Creator:: Wilson, Christopher D.
Abstract:: The use of some age determination methods may result in the incorrect age structure of fish populations. This in turn may lead to incorporation of inappropriate data into models used for stock management. Otoliths are commonly used for determining the age of fishes, and ages based on the whole otoliths...

The effects of concentration and particle size of suspended materials on growth and condition of the Pacific oyster (Crassostrea gigas)

Creator:: Wilson, William Joseph
Abstract:: The effects of exposure to suspended silt, kaolin and fuller's earth on growth and condition of Pacific oysters, 16 months of age, were studied. The exposure apparatus maintained a continuous flow of turbid water through chambers containing test oysters. Additional studies measured the filtration rates of oysters exposed to suspended...

Behavior and survival of coho salmon, Oncorhynchus kisutch (Walbaum), in Sashin Creek, southeastern Alaska

Creator:: Crone, Richard Allan
Abstract:: Behavior and survival in fresh water were studied for three brood years of coho salmon in Sashin Creek, Alaska, from October 1963, until September 1966. Investigations of spawning adults were conducted to determine numbers of spawners, distribution on the spawning grounds, effects on pink salmon, age composition, redd life, fecundities,...

Formulation of a synthetic seawater for bioassays with Mytilus edulis embryos

Creator:: Courtright, Robert Carl
Abstract:: Commerical preparations and published formulations using reagent chemicals for seawater substitutes were not biologically acceptable to Mytilus edulis embryos, in that calcification did not occur. When Leslie coarse hide salt was used as the source of NaCl for literature formulations, most formulas provided some success in the development, growth and...

The effects of natural fire and recreational disturbance on montane forest ecosystem composition, structure and nitrogen dynamics, Crater Lake National Park, Oregon

Creator:: Wilson, John K. (John Kevin)
Abstract:: Disturbance, whether natural or of human origin, modifies to varying degrees many ecosystem attributes. Fire is a natural process in the montane forests of southern Oregon but for much of the 20th century fire was viewed as an apocalypse and thus fervently suppressed. Effective natural resource management requires an understanding...

Orientation and homing of the brush rabbit

Creator:: Chapman, Joseph A.
Abstract:: A study of orientation and homing in brush rabbits, Sylvilagus bachmani ubericolor (Miller), was conducted on the E. E. Wilson Game Management Area 7 miles north of Corvallis, Oregon, between July 1967 and April 1969. Sixty-seven individual rabbits were fitted with radio-transmitters and returned to the field. Home ranges were...
