I'm interested in how plant-animal interactions shape ecological communities. I focus on seed-dispersal because of its importance in structuring tropical forests and the complexity and diversity of interactions that occur as a seed grows into a tree. My dissertation work is based in the remnants of the Chocó forests of northwestern Ecuador.

My interests in conservation and management of threatened species and ecosystems have directed my research on understanding the ecological interactions that regulate population viability of wildlife species.  In 2003 I received a M.S. from Oregon State University for my research on cavity-nesting bird and forest structure response to silvicultural treatments.  From 2006 to present I have maintained an active research program across coastal islands in the northern Gulf of Mexico. In 2012 I received a Ph.D. for this work from the University of Louisiana (major advisor: Paul Leberg), which led to my current post-doctoral position under Jordan Karubian at Tulane University.  We are evaluating what factors influence the efficiency of different foraging patterns across individuals, time, and environmental gradients.

I am interested in behavioral ecology and sexual selection. My research focuses on how environmental heterogeneity can affect sexual and social selection, and the subsequent effects on individual-level fitness. I conduct research on red-backed fairy-wrens in the Northern Territory of Australia. Find out more by visiting my research blog. Previously, I received my MS from Florida Atlantic University where I studied the effects of environmental factors on wading bird foraging in the Everglades, and I have done field work in Australia, Panama, Costa Rica, the Mariana Islands, and the US. 


Jenny Hazlehurst, Ph.D. student

My research focuses on the interactions between hummingbirds and the plants they pollinate in the cloud and montane forests of Manu National Park, Perú. Current research is focused on how plants budget resources to their reproduction to balance the effects of legitimate hummingbird pollinators and nectar-robbing flower-piercers on the plant's reproductive success. I am also interested in how changes in pollinator community structure along altitudinal and human disturbance gradients impacts the reproductive strategy and success of Andean plants. 

Catherine Wilcoxson, 4+1 MS student

I am a 4+1 student from Peru, Illinois, pursuing an M.S. in Environmental Biology. I received a B.S. in Environmental Biology and a B.A. in music from Tulane University. I am currently studying reflectance of white-shouldered fairy wren plumage using spectrometry. I am interested in determining the origin and benefits of female ornamentation using white-shouldered fairy wrens as a study system.
