Research Interests

 

I am interested in the fields of conservation biology, landscape ecology, and global change biology.  I am primarily focused on investigating how spatial analyses can be used to inform conservation planning and to answer basic ecological questions.

Monitoring the Effects of Climate on Southern Appalachian Forest Phenology

 

Current research indicates that warming global temperatures are capable of altering phenological cycles in deciduous forests.  Potential climate induced changes to deciduous forest phenology are particularly important as they form the base for higher level trophic interactions and affect carbon and water cycles.  The objective of this research is to evaluate the effectiveness of remotely-sensed MODIS imagery to monitor deciduous forest phenology and predict effects of temperature variability in the Southern Appalachians.  We test the ability of satellite data to predict phenological events by comparing to intensive field observations of canopy and understory spring greenup.  Additionally, we utilize local temperature models and landscape level forest phenology data to test hypotheses regarding the relative influence of winter chilling, spring warming, and topographic variables on the timing spring leaf emergence.  This study furthers knowledge on the interpretation of satellite-based phenology in mountainous regions where such studies have been lacking.  Results from this study will inform companion studies on Black-throated Blue Warbler demography in the Southern Appalachians and will improve understanding of how climate change may impact this ecosystem.
