Introduction
Our lab is broadly interested in applied ecological questions. However, more specifically our work involves investigations of wildlife and vegetation response to management practices within a multi-scale context. The ultimate goal of our research is to inform management decisions of landowners, habitat practitioners, and agency partners. A future direction of our lab hopes to explore associations between species traits (i.e. functional, biological, and conservation-related) and habitat.

Knowledge of movements, habitat use, and resource requirements is critical to designing management strategies for species with a conservation status. For snakes, basic research needed to derive this information is often lacking or insufficient. We used radio telemetry to investigate the spatial ecology and habitat use of 21 adult Western Foxsnakes...

The pattern of increased nest defense effort over the course of a nesting season could result from three distinct (albeit non-exclusive) mechanisms: increased value of offspring to parents with progression toward independence (parental investment theory), decreased opportunity for renesting (renesting potential hypothesis), or decreased perceived c...

Birds may respond to habitat at multiple scales, ranging from microhabitat structure to landscape composition. North American grassland bird distributions predominantly reside on private lands, and populations have been consistently declining. Many of these lands are enrolled in U.S. federal conservation programmes, and properly guided management p...
Article
Policy-driven conservation on private lands, such as the U.S. Farm Bill’s Conservation Reserve Program (CRP), provides crucial habitat for consistently declining populations of grassland birds. In 2004, new CRP enrollments were required to be managed to floristically diversify old grass-dominated fields and provide early-successional habitat. Oblig...

Polyvinyl chloride (PVC) pipe refugia have been used to study hylid treefrogs for decades. These inexpensive and easy-to-build refugia effectively mimic damp tree cavities but pose a hazard for small mammals that fall into pipes and cannot climb up smooth surfaces. Borg et al. (2004) found that by installing escape ropes, Southern Flying Squirrels...

Overviews our research on using an escape rope to reduce accidental mammal mortality in treefrog studies using PVC pipes. Our study found a complete reduction of mammal mortality and a small, non-statistically significant reduction in treefrog captures.

Generally, the number of Illinois Avian Species of Greatest Conservation Need declines with increasing amounts of bush honeysuckle (Lonicera maackii). Honeysuckle's impact on forest birds may be associated with their habitat guild (i.e. canopy, mid-story, and understory) See P. Rathz presentation here: https://youtu.be/nKy8sEk12qs?t=3782

Sustaining agricultural environments requires explicit recognition of the services provided by landscapes, particularly cultural ecosystem services that are contested and underrepresented in previous research. We assembled and engaged a panel of experts to identify and deliberate on the relationships among ecosystem services, threats and land manag...

Bush honeysuckle (Lonicera spp.), an invasive shrub of the Midwestern United States, often replaces native understory shrubs and woodland vegetation. To improve the health and function of Midwestern forested ecosystems, it is vital to control honeysuckle through management. The use of aerial herbicide application to control infested honeysuckle are...

Bush honeysuckle (Lonicera Maackii) is a shrub native to Asia that was originally introduced to North America for landscape ornamentals, erosion control and wildlife cover. In the Midwestern and Eastern United States, it outcompetes native plant species by forming a thick understory that limits sunlight and impedes seedling establishment. It also c...
Thesis
Full-text available
North American populations of grassland birds have been declining consistently for the past several decades. Grassland birds respond to multiple scales which encompass a spectrum of habitat variables, and the habitat scale of importance may depend on the response of interest. For practitioners, having knowledge of the effect of scale is useful beca...

Few researchers have used radiotelemetry to study spatial organization in beavers (Castor canadensis) given limitations in available radio-attachment methods for the species. During Mar. 2005–Sept. 2006, we attached tail-mounted transmitters to 46 beavers from 10 colonies in an unexploited beaver population in southern Illinois. We used radioteleme...

For corvids, the decision to cache is a complex behavior likely influenced by many interacting factors. On 8 April 2004, I observed an American Crow (Corvus brachyrhynchos) caching eastern cottontail (Sylvilagus floridanus) kits taken from a rabbit nest on the Missouri State University campus in Springfield, Missouri. The crow cached at least three...

Many studies have examined aspects of ecology and behavior in West Indian anoles, but few have addressed sleeping behavior. Most information on sleeping anoles is anecdotal, including brief notations of perch height and position, vegetation preference, coloration, and waking behavior (e.g., Schwartz and Henderson, 1991). Only one quantitative study...

To determine the effectiveness of aerial application, prescribed fire management, and other management practices to control and eradicate bush honeysuckle in southwestern Illinois. We are specifically investigating forest bird, gray treefrog, and native flora community responses to these management regimes.
