The Ecology Of The Dominant Tick Species In The Northwestern Portion Of The Dismal Swamp National Wildlife Refuge, Mary Keith Garrett

Biological Sciences Theses & Dissertations

Elements of the ecology of the two dominant man-biting ticks were studied during 1971-1973 in two locations in Southeastern Virginia, namely, what is now the Dismal Swamp National Wildlife Refuge and Newport News City Park. Tick species composition, relative abundance, density, and distribution in the two areas were compared. In addition, the Dismal Swamp locality was used as a test area for studies on the survival of native, lab reared and translocated Dermacentor variabilis (Say) and Amblvomma americanum (L.) in relation to selected abiotic factors. The Newport News locality served as a control area for these studies.

Factors Affecting Nesting Success Of The Canvasback In The Aspen Parklands, Jerome H. Stoudt

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The Minnedosa study area is located in the southwestern portion of Manitoba just south of the town of Minnedosa. It is 90 square miles in size and roughly square in shape. The Aspen Parkland, in which the study area is located, is characterized by gently rolling terrain and black soils. Mixed farming is the rule with emphasis on small grain production consisting of wheat, barley, and oats. Roughly 50 percent of the water areas in the parkland are ringed with aspen, Populus tremuloides, and large blocks of aspen are interspersed throughout the area. The Minnedosa area differs because of …
