Research Focus

Oak Woodland

Work in my lab includes projects that focus on a variety of organisms and scales from single species population dynamics and habitat suitability analyses to landscape-scale multispecies reserve designs. Many of these studies focus on the biodiversity hotspot of the Oak Openings Region of Northwest Ohio.

We use a variety of techniques including:

Research Questions

Schetter and Root 2011 Landcover
  1. Where are they?  We always examine the spatial constraints of species, ecosystems, and their distributions. We may simply map out where a focal species occurs or use censusing techniques to carefully delineate their habitat or even build habitat models to predict areas of suitable habitat based on critical characteristics. This relies heavily on GIS, remote sensing, and spatial statistics.
  2. Are they viable? We also look at factors that affect long-term persistence of species by measuring abundance, survival and dispersal. This may be through mark-recapture studies that directly monitor the populations, indirect methods of estimating survival or activity, evaluation of factors that affect populations and abundance or detailed spatially-explicit population modeling. This relies heavily on basic ecological approaches combined with stochastic modeling.
  3. How can we conserve/manage them? All of the projects incorporate some element of management and its impact on the focal species or system. In some cases this is unavoidable since many of the habitats we are studying require active management. We may directly measure the impacts of management actions (e.g., prescribed burning or mowing) on habitat characteristics or demographic rates (e.g., survival, fecundity, abundance) for a species. Our studies usually produce some management recommendations for improving the fate of native species.
