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.

A generalizable energetics-based model of avian migration to facilitate continental-scale waterbird conservation
Conserving migratory birds is made especially difficult because of movement among spatially disparate locations across the annual cycle. In light of challenges presented by the scale and ecology of migratory birds, successful conservation requires integrating objectives, management, and monitoring across scales, from local management units to ecoregional and flyway administrative boundaries. We prAuthorsEric V. Lonsdorf, Wayne E. Thogmartin, Sarah Jacobi, Jorge Coppen, Amélie Y. Davis, Timothy J. Fox, Patricia J. Heglund, Rex Johnson, Tim Jones, Kevin P. Kenow, James E. Lyons, Kirsten E. Luke, Shannon Still, Brian G. TaverniaRelating mesocarnivore relative abundance to anthropogenic land-use with a hierarchical spatial count model
There is growing need to develop models of spatial patterns in animal abundance, yet comparatively few examples of such models exist. This is especially true in situations where the abundance of one species may inhibit that of another, such as the intensively-farmed landscape of the Prairie Pothole Region (PPR) of the central United States, where waterfowl production is largely constrained by mesoAuthorsShawn M.

White-nose syndrome (WNS) was first detected in North American bats in New York in 2006. Since that time WNS has spread throughout the northeastern United States, southeastern Canada, and southwest across Pennsylvania and as far west as Missouri. Suspect WNS cases have been identified in Minnesota and Iowa, and the causative agent of WNS (Pseudogymnoascus destructans) has recently been detected inAuthorsRobin E. Russell, Wayne E. Thogmartin, Richard A. Erickson, Jennifer A. Szymanski, Karl TinsleySpring plant phenology and false springs in the conterminous US during the 21st century
The onset of spring plant growth has shifted earlier in the year over the past several decades due to rising global temperatures. Earlier spring onset may cause phenological mismatches between the availability of plant resources and dependent animals, and potentially lead to more false springs, when subsequent freezing temperatures damage new plant growth. We used the extended spring indices to prAuthorsAndrew J. Allstadt, Stephen J. Vavrus, Patricia J. Heglund, Anna M. Pidgeon, Wayne E. Thogmartin, Volker C.

Knowledge of factors influencing animal abundance is important to wildlife biologists developing management plans. This is especially true for economically important species such as blackbirds (Icteridae), which cause more than $100 million in crop damages annually in the United States. Using data from the North American Breeding Bird Survey, the National Land Cover Dataset, and the National ClimaAuthorsGreg M. Forcey, Wayne E. Thogmartin, George M. Linz, Patrick C. McKann, Shawn M. CrimminsThe importance of range edges for an irruptive species during extreme weather events
Context Threats to wildlife species from extreme events, such as droughts, are predicted to increase in frequency and magnitude with climate change. Extreme events can cause mortality and community-level changes, but for some mobile species, movement away from areas affected may be a viable option. Objectives We examined the effect of extreme weather on spatial patterns of abundance for an irruptiAuthorsBrooke L. Bateman, Anna M. Pidgeon, Volker C. Radeloff, Andrew J. Allstadt, H.

The purpose of the North American Bat Monitoring Program (NABat) is to create a continent-wide program to monitor bats at local to rangewide scales that will provide reliable data to promote effective conservation decisionmaking and the long-term viability of bat populations across the continent. This is an international, multiagency program. Four approaches will be used to gather monitoring dataAuthorsSusan C. Loeb, Thomas J. Rodhouse, Laura E. Ellison, Cori L. Lausen, Jonathan D.

The health of tree swallows, Tachycineta bicolor, on the Upper Mississippi River (UMR) was assessed in 2010 and 2011 using biomarkers at six sites downriver of Minneapolis/St. Paul, MN metropolitan area, a tributary into the UMR, and a nearby lake.

Resource managers are increasingly tasked with developing habitat conservation plans in the face of numerous, sometimes competing, objectives. These plans must often be implemented across dispersed habitat conservation units that may contribute unequally to overall conservation objectives.

The U.S. Geological Survey has developed a methodology to assess the impacts of wind energy development on wildlife; it is a probabilistic, quantitative assessment methodology that can communicate to decision makers and the public the magnitude of these effects on species populations. The methodology is currently applicable to birds and bats, focuses primarily on the effects of collisions, and canAuthorsJames E. Diffendorfer, Julie A. Beston, Matthew D. Merrill, Jessica C.

Conservation planning can be challenging due to the need to balance biological concerns about population viability with social concerns about the benefits biodiversity provide to society, often while operating under a limited budget. Methods and tools that help prioritize conservation actions are critical for the management of at-risk species.

MedellínA stage-structured, spatially explicit migration model for Myotis bats: mortality location affects system dynamics
Bats are ecologically and economically important species because they consume insects, transport nutrients, and pollinate flowers. Many species of bats, including those in the Myotis genus, are facing population decline and increased extinction risk. Despite these conservation concerns, few models exist for providing insight into the population dynamics of bats in a spatially explicit context.AuthorsRichard A. Erickson, Wayne E.
