Sensitivity Analyses of a Population Projection Model of Ring-Necked Pheasants (2008)

William R. Clark, Todd R. Bogenschutz, Dale H. Tessin

A large literature exists on population dynamics of ring-necked pheasant (Phasianus colchicus) in North America, but there has not been an attempt to formulate a matrix model nor a sensitivity...

Demographic Processes Influencing Population Viability of the Iowa Pleistocene Snail (Discus Macclintocki) (2008)

William R. Clark, Catherine J. Henry, Connie L. Dettman

Understanding the importance of variable local population abundance and the limited potential for dispersal and genetic exchange is crucial for the conservation of many species with limited...

Space Use and Habitat Selection by Bobcats in the Fragmented Landscape of South-Central Iowa (2008)

Stephanie A. Tucker, William R. Clark, Todd E. Gosselink

Historically, bobcats (Lynx rufus) were found throughout the Corn Belt region, but they nearly disappeared from this area due to habitat loss and unregulated harvest that occurred during the century...

Sampling Considerations for Disease Surveillance in Wildlife Populations (2008)

Sarah M. Nusser, William R. Clark, David L. Otis, Ling Huang

Disease surveillance in wildlife populations involves detecting the presence of a disease, characterizing its prevalence and spread, and subsequent monitoring. A probability sample of animals...

A Model of the Productivity of the Northern Pintail. (1997)

Clark, William R., Klaas, Erwin E.

In response to the need for a modeling system for the northern pintail (anas acuta), we adapted the productivity component of the mallard model to northern pintails. We modified only the productivity...

Rodent Populations and Crop Damage in Minimum Tillage Corn Fields (1983)

Young, Richard E., Clark, William R.

No-till and disked cornfields were examined in southwest Iowa to determine small mammal population densities, movements, and impacts of rodent depredations on corn seedlings. Two replicates of the...

THE SUMMER EUROPEAN STARLING PROBLEM IN TULARE COUNTY (1967)

Clark, William R.

Summer starlings (Sturnus vulgaris) are known to have caused damage to the agricultural industry of Tulare County since 1960. At this time the first confirmed appreciable damage to grapes occurred....

A Role for Perforin in Downregulating T-Cell Responses during Chronic Viral Infection

Matloubian, Mehrdad, Suresh, M., Glass, Alison, Galvan, Marisa, Chow, Kit, Whitmire, Jason K., ...

Cytotoxic T cells secrete perforin to kill virus-infected cells. In this study we show that perforin also plays a role in immune regulation. Perforin-deficient (perf −/−) mice chronically...

Fas (CD95)-Dependent Cell-Mediated Immunity to Listeria monocytogenes

Jensen, Eric R., Glass, Alison A., Clark, William R., Wing, Edward J., Miller, Jeff F., Gregory, Stephen H.

Two distinct and complementary pathways, one mediated by perforin and the other dependent upon CD95 (Fas), effect cell-mediated cytotoxicity. We examined the relative roles of these pathways in host...

Importance of Hepatic Portal Circulation for Insulin Action in Streptozotocin-Diabetic Rats Transplanted with Fetal Pancreases

Brown, Josiah, Mullen, Yoko, Clark, William R., Molnar, I. Gabriella, Heininger, Diane

The importance of the hepatic portal circulation in the response to insulin was assessed in streptozotocin-diabetic rats transplanted with syngeneic fetal pancreases. Partial reversal of diabetes was...
