Brief description of current research:

I take a landscape approach to investigating issues relative to climate change and biodiversity.  Thus have incorporated many of the approaches from the field of landscape ecology, using tools such as remote sensing and GIS.  My montane meadow research in the Greater Yellowstone Ecosystem provides insight into how a relatively pristine community exhibits interannual change relative to climatic variation.  I have been monitoring 55 montane meadows since 1997 and these meadows are arrayed along a hydrological gradient from hydric to mesic to xeric.  The beauty of this study system is that 1) there is a wide range of soil moisture conditions within a small geographic distance, and 2) given that this is a relatively water-limited system, it provides an opportunity to observe large-scale changes in plant and animal distribution patterns relative to rather small-scale changes in soil moisture.  Much of my recent work includes a synthesis of long-term ecological data, focusing on how species distributions of plants, birds, and butterflies change relative to interannual variation in precipitation and temperature.  My next steps include testing hypotheses regarding the mechanisms for these community changes via experimental manipulations of soil water content.
