Objectives and Metrics for Wildlife Monitoring (2008)
John R. Sauer, Melinda G. Knutson
Monitoring surveys allow managers to document system status and provide the quantitative basis for management decision-making, and large amounts of effort and funding are devoted to monitoring....
A Hierarchical Model for Estimating Change in American Woodcock Populations (2008)
John R. Sauer, William A. Link, William L. Kendall, James R. Kelley, Daniel K. Niven
The Singing-Ground Survey (SGS) is a primary source of information on population change for American woodcock (Scolopax minor). We analyzed the SGS using a hierarchical log-linear model and compared...
William A. Link, John R. Sauer, Daniel K. Niven
Annual surveys of wildlife populations provide information about annual rates of change in populations but provide no information about when such changes occur. However, by combining data from 2...

William A. Link, John R. Sauer, Daniel K. Niven
Analysis of Christmas Bird Count (CBC) data is complicated by the need to account for variation in effort on counts and to provide summaries over large geographic regions. We describe a hierarchical...
Predicting Regional Abundance of Rare Grassland Birds with a Hierarchical Spatial Count Model (2006)
Wayne E. Thogmartin, Melinda G. Knutson, John R. Sauer
Grassland birds are among the most imperiled groups of birds in North America. Unfortunately, little is known about the location of regional concentrations of these birds, thus regional or statewide...
ENHANCING THE SCIENTIFIC VALUE OF THE CHRISTMAS BIRD COUNT (2005)
Erica H. Dunn, Charles M. Francis, Peter J. Blancher, Susan Roney Drennan, Marshall A. Howe, Denis Lepage, ...
ESTIMATING POPULATION TRENDS WITH A LINEAR MODEL: TECHNICAL COMMENTS (2004)
John R. Sauer, William A. Link, J. Andrew Royle
Controversy has sometimes arisen over whether there is a need to accommodate the limitations of survey design in estimating population change from the count data collected in bird surveys. Analyses...
SCIENCE FOR AVIAN CONSERVATION: PRIORITIES FOR THE NEW MILLENNIUM (2003)

An Evaluation of Population Index and Estimation Techniques for Tadpoles in Desert Pools (2002)
Robin E. Jung, Gage H. Dayton, Stephen J. Williamson, John R. Sauer, Sam Droege
Using visual (VI) and dip net indices (DI) and double-observer (DOE), removal (RE), and neutral red dye capture-recapture (CRE) estimates, we counted, estimated, and censused Couch's spadefoot...
A REMOVAL MODEL FOR ESTIMATING DETECTION PROBABILITIES FROM POINT-COUNT SURVEYS (2002)

North American Breeding Bird Survey Annual Summary, 1989. (1997)
The North American Breeding Bird Survey (BBS) is run by approximately 2,000 skilled amateur ornithologists and is coordinated cooperatively by the U.S. Fish and Wildlife Service and the Canadian...
Growth rates and mass-based demography of small mammals /--by John R. Sauer. (1985)
Thesis (Ph. D.)--University of Kansas, Systematics and Ecology, 1985.
Role of Cyclic Nucleotides and Calcium in Controlling Tick Salivary Gland Function (1984)
SAUER, JOHN R., ESSENBERG, R. C.
The paired salivary glands of female ixodid ticks are essential organs of osmoregulation. As the female feeds, the rate of salivary fluid secretion increases greatly enabling the tick to concentrate...
The population ecology of Wapiti in northwestern Wyoming /--by John R. Sauer. (1980)
Thesis (M.S.)--University of Wyoming.
Higher temporal variability of forest breeding bird communities in fragmented landscapes
Boulinier, Thierry, Nichols, James D., Hines, James E., Sauer, John R., Flather, Curtis H., Pollock, Kenneth H.
Understanding the relationship between animal community dynamics and landscape structure has become a priority for biodiversity conservation. In particular, predicting the effects of habitat...
Disruption of Ixodes scapularis anticoagulation by using RNA interference
Narasimhan, Sukanya, Montgomery, Ruth R., DePonte, Kathleen, Tschudi, Christian, Marcantonio, Nancy, Anderson, John F., ...
Ixodes scapularis ticks transmit many pathogens, including Borrelia burgdorferi, Anaplasma phagocytophilum, and Babesia microti. Vaccines directed against arthropod proteins injected into the host...

Application of RNA Interference in Tick Salivary Gland Research
Ramakrishnan, Vijay G., Aljamali, Majd N., Sauer, John R., Essenberg, Richard C.
Ticks are obligate ectoparasites that feed on a variety of hosts including mammals, birds and reptiles. Prolonged attachment on the host and an ability to transmit a wide variety of pathogens are the...
