Wayne E Thogmartin, PhD
I am a quantitative ecologist conducting scholarly research at the intersection of animal ecology, spatial analyses, and statistics.
My interests are in population ecology for animals declining in abundance, asking new questions of multiple, combined data sets to gain novel insight into the dynamics of animal populations, and translating science into guidance for practical management decisions.

No abstract available.AuthorsJason J. Rohweder, Sara Vacek, Wayne E. ThogmartinDecline of shortjaw cisco in Lake Superior: the role of overfishing and risk of extinction
Recent reviews have further documented the decline of the shortjaw cisco Coregonus zenithicus in Lake Superior. This fish was the most abundant deepwater cisco species in Lake Superior in the early 1920s but presently makes up less than 1% of all deepwater ciscoes (i.e., including shortjaw cisco, bloater C. hoyi, and kiyi C. kiyi) captured in biological surveys. Directed overfishing of deepwater cAuthorsCharles R. Bronte, Michael H. Hoff, Owen T. Gorman, Wayne E. Thogmartin, Philip J. Schneeberger, Thomas N. ToddMultiscale habitat selection by Ruffed Grouse at low population densities
Theory suggests habitats should be chosen according to their relative evolutionary benefits and costs. It has been hypothesized that aspen (Populus spp.) forests provide optimal habitat for Ruffed Grouse (Bonasa umbellus). We used the low phase of a grouse population's cycle to assess the prediction that grouse should occupy aspen and avoid other forest types at low population density because of tAuthorsG.S.

Floodplain habitat provides important migration and breeding habitat for birds in the midwestern United States. However, few studies have examined how the avian assemblage changes with different stages of floodplain forest succession in the midwestern United States. In spring and summer from 2002 to 2004, we conducted 839 point counts in wet prairie/forbs fields, 547 point counts in early successiAuthorsW.E. Thogmartin, M. Gallagher, N. Young, J.J. Rohweder, F. Durbian, M. G. KnutsonFactors associated with succession of abandoned agricultural lands along the Lower Missouri River, U.S.A
The 1993 flood of the Missouri River led to the abandonment of agriculture on considerable land in the floodplain. This abandonment led to a restoration opportunity for the U.S. Federal Government, purchasing those lands being sold by farmers. Restoration of this floodplain is complicated, however, by an imperfect understanding of its past environmental and vegetative conditions. We examined envirAuthorsW.E. Thogmartin, M. Gallagher, N.

Partners in Flight (PIF), a public–private coalition for the conservation of land birds, has developed one of four international bird conservation plans recognized under the auspices of the North American Bird Conservation Initiative (NABCI). Partners in Flight prioritized species most in need of conservation attention and set range-wide population goals for 448 species of terrestrial birds. PartnAuthorsJane A. Fitzgerald, Wayne E. Thogmartin, Randy Dettmers, Tim Jones, Christopher Rustay, Janet M. Ruth, Frank R. Thompson, Tom WillRelationship of obligate grassland birds to landscape structure in Wisconsin
Conservation plans for grassland birds have included recommendations at the landscape level, but species' responses to landscape structure are variable. We studied the relationships between grassland bird abundances and landscape structure in 800-ha landscapes in Wisconsin, USA, using roadside surveys. Of 9 species considered, abundances of only 4 species differed among landscapes with varying amoAuthorsL.D. Murray, C. A. Ribic, W.E. ThogmartinMulti-scale responses of vegetation to removal of horse grazing from Great Basin (USA) mountain ranges
Although free-roaming equids occur on all of the world's continents except Antarctica, very few studies (and none in the Great Basin, USA) have either investigated their grazing effects on vegetation at more than one spatial scale or compared characteristics of areas from which grazing has been removed to those of currently grazed areas. We compared characteristics of vegetation at 19 sites in ninAuthorsE.A. Beever, R.J. Tausch, W.E. ThogmartinModeling wetland blackbird populations as a function of waterfowl abundance in the prairie pothole region of the United States and Canada
Blackbirds share wetland habitat with many waterfowl species in Bird Conservation Region 11 (BCR 11), the prairie potholes. Because of similar habitat preferences, there may be associations between blackbird populations and populations of one or more species of waterfowl in BCR11. This study models populations of red-winged blackbirds and yellow-headed blackbirds as a function of multiple waterfowAuthorsG.M. Forcey, G.M. Linz, W.E. Thogmartin, W.J. BleierPower to detect trend in short-term time series of bird abundance
Avian point counts for population monitoring are often collected over a short timespan (e.g., 3-5 years). We examined whether power was adequate (power ???0.80) in short-duration studies to warrant the calculation of trend estimates. We modeled power to detect trends in abundance indices of eight bird species occurring across three floodplain habitats (wet prairie, early successional forest, and mAuthorsW.E. Thogmartin, B. R. Gray, M. Gallagher, N. Young, J.J. Rohweder, M. G. KnutsonScaling local species-habitat relations to the larger landscape with a hierarchical spatial count model
Much of what is known about avian species-habitat relations has been derived from studies of birds at local scales. It is entirely unclear whether the relations observed at these scales translate to the larger landscape in a predictable linear fashion. We derived habitat models and mapped predicted abundances for three forest bird species of eastern North America using bird counts, environmental vAuthorsW.E. Thogmartin, M. G. KnutsonInfluence of land use and climate on wetland breeding birds in the Prairie Pothole region of Canada
Bird populations are influenced by a variety of factors at both small and large scales that range from the presence of suitable nesting habitat, predators, and food supplies to climate conditions and land-use patterns. We evaluated the influences of regional climate and land-use variables on wetland breeding birds in the Canada section of Bird Conservation Region 11 (CA-BCR11), the Prairie PotholeAuthorsG.M.
