Heather Cayton, Managing Director

Heather Cayton is a Research Technician at North Carolina State University and the Managing Director of She received her B.S. from the University of Virginia and her M.S. from Virginia Tech, and has spent the past five years studying corridors and rare butterflies in North Carolina. Heather’s recent digests.

Nick Haddad, Research Scientist

Dr. Nick Haddad is William Neal Reynolds Distinguished Professor of Biology at North Carolina State University. For more than 20 years, he has been studying how plants and animals use corridors. He has worked in the largest and longest-running corridor experiment, the Savannah River Site Corridor Project, and he has studied natural corridors used by rare butterflies. Nick’s recent digests.

Neil McCoy, Graphic Designer

Neil McCoy is a graphic designer and science communicator who specializes in web design and development for science content. He collaborates with researchers and educators to visualize and present science in creative ways and to create websites for research extension and outreach, science education, and research tools.


Peter Brewitt

Peter Brewitt is a PhD candidate in Environmental Studies at the University of California, Santa Cruz. He received his BA in History from Dartmouth College before moving into the sciences. His dissertation focuses on dam removal as an ecological and political phenomenon in the Pacific Northwest and California. He became interested in dam removal during his three years working as a naturalist in Yosemite National Park, home to the former Hetch Hetchy Valley. Peter’s recent digests.

Christine Brown

Christine Brown is a PhD candidate at North Carolina State University. She works with Dr. Nick Haddad studying the effects of corridors on spider resource subsidies for the Corridor Project at Savannah River Site, SC. She enjoys studying the dramas of tiny predators, likening them to little cougars and wolves, but with more replication. For more: Christine’s recent digests.

John Herrmann

John Herrmann received his Master’s in 2006 from the University of Hohenheim (Germany) and Visayas State University (Philippines) for research on pollinators in sustainable farming systems. He completed his Ph.D. in 2010 at the University of Bern (Switzerland) on the effects of woody habitat fragmentation on arthropods and birds. Afterwards, he conducted a project at the Ben-Gurion University of the Negev (Israel) to examine the impact of Eucalyptus plantations on native arthropods. Between 2011 and 2014, he was working for the University of Washington to investigate the effects of habitat corridors on seed and arthropod dispersal. John’s recent digests.

Clinton Jenkins

Clinton Jenkins is a Research Scholar in the Biology Department of North Carolina State University and a Visiting Scholar at Duke University. He earned his PhD in Ecology and Evolutionary Biology at the University of Tennessee under the advisement of Dr. Stuart Pimm. Clinton also teaches Conservation GIS and Advanced Spatial Analysis at the Instituto de Pesquisas Ecológicas in Nazaré Paulista, Brazil, one of Brazil’s premier conservation organizations. Clinton’s recent digests.

Julian Resasco

Julian Resasco is a post-doctoral fellow in the Department of Ecology and Evolutionary Biology at the University of Colorado at Boulder. He did his dissertation research on ant community ecology and corridors at the Savannah River Site Corridor Project. As a post-doctoral fellow, Julian is working on habitat fragmentation effects on arthropod trophic structure within the Wog Wog Habiat Fragmentation Experiment in New South Wales, Australia. For more check out: Julian’s recent digests.

Anne Trainor

Anne Trainor is a post-doctoral associate in Yale University’s School of Forestry and Environmental Studies and served as as a coordinator and a key participant in the Yale Climate Adaptation Framework. As a NatureNet Fellow, Anne is currently integrating her expertise in ecological principles and geospatial modeling to build an approach that can help conservationists keep landscapes functional and connected while identifying and prioritizing energy portfolios for uncertain future conditions. Anne’s recent digests.

Tyson Wepprich

Tyson Wepprich is a PhD student at North Carolina State University. He researches insect responses to climate warming and conservation strategies resilient to global changes. After growing up in St. Charles, Missouri, Tyson came to North Carolina to go to Duke University. Before starting graduate school, he taught science in the Great Smoky Mountains National Park, his favorite place in the Eastern US. Tyson’s recent digests.

Marit Wilkerson

As an AAAS S&T Policy Fellow, Dr. Marit Wilkerson serves as a climate change advisor for the Africa Bureau for the United States Agency for International Development (USAID) in Washington, D.C. With the University of California, Davis, her dissertation work centered on invasive plants in conservation corridors, and her motivating passion is to promote conservation science and ethics to a broader public through applied research and real-world outreach.

Johnny Wilson

Johnny Wilson recently received his PhD from North Carolina State University, which focused on conservation planning in a changing world. Originally from South Africa, he received his MSc at the University of Pretoria. He constantly struggles to find enough time for birdwatching (More at Johnny’s recent digests.

Sara Zeigler

Sara Zeigler is a postdoctoral research associate in the Department of Biological Sciences at Virginia Tech, where her research centers on developing models that simulate how landcover change and management in longleaf pine ecosystems impact red-cockaded woodpeckers. She did her PhD at the University of Maryland under Drs. Bill Fagan and Ruth DeFries. Her work focuses on the intersection of landscape processes and population dynamics for endangered species conservation. Sara’s recent digests.
