My research tests the ability of macroecological theories to predict local patterns of diversity, abundance, and demography. By determining the aspects of theory most relevant to the scale of observable interactions, I hope to improve both theoretical understanding and practical knowledge of species community dynamics. In general my research merges a strong organismal biology focus with a theoretical and statistical approach. The organismal focus of my research is on terrestrial insect herbivores, especially forest moth caterpillars (Lepidoptera). Due to their high species diversity, tractable and quantifiable life history variation, and importance as primary consumers in many forest systems, they are an ideal terrestrial animal group with which to evaluate hypotheses of community ecology, animal behavior, and trophic interactions. My theoretical approach focuses on the theories of community dynamics and plant-insect interactions, broadly defined. For example, I have used insect herbivore assemblages to test hypotheses put forward by neutral theories of biodiversity, metabolic theory of ecology, and ecological stoichiometry.
As a post-doctoral fellow in the Parker lab I am focused on exploring two aspects of two forms of environmental change, namely exotic species invasion and overabundant white-tailed deer. I am investigating differences in native and exotic traits, especially plant defensive chemistry, on herbivory by native insects. I am also investigating the ability of deer browsing to alter native herbivore communities by shifting plant community structure and phenotype.
