Short Biography

Allan O'Connell currently directs the quantitative modeling and monitoring branch of the U.S. Geological Survey's Patuxent Wildlife Research Center (PWRC) in Laurel, MD, the world-renowned ecological research center known for it's work on ecotoxicology, endangered species conservation, and population ecology.  He is originally from New York City where he grew up in the shadows of the American Museum of Natural History (his father worked his entire career in the Ornithology Department).  He has 30+ years of experience with the U.S. Department of Interior as a field biologist, natural resource and science program manager, research scientist, and most recently as a supervisory fish and wildlife administrator.  He has held a variety of positions during this time including research scientist and research manager (USGS Patuxent), acting chief of the National Bird Banding Laboratory (USGS, Patuxent), first director of the National Park Service's (NPS) Cooperative Research Unit at the Univeristy of Maine's flagship campus in Orono (NPS and USGS), division chief for natural resource management and science at Acadia National Park (ME) and Fire Island National Seashore (NY).  He has also worked as a biologist for the NPS at Gateway National Recreation Area (NY) and Fire Island, and began his career with the U.S. Department of Agriculture, Animal And Plant Health Inspection Service as a plant quarantine inspector at Kennedy Airport. He holds a B.S. in Biology (Wagner College, NY), M.S. in Zoology (New York University) and a Ph.D. in Wildlife Ecology (University of Massachusetts). He has over 40 technical publications and is the principal co-editor (and co-author of several chapters) of the book published (2011) by Springer Verlag - Camera Traps in Animal Ecology: Methods and Analyses, a treatise on the use and application of camera trapping, the technique that is revolutionizing how wildlife populations are being sampled around the world. His most recent work involves endangered species: use of camera trap data to develop population density estimates for the Florida panther, assessing the effects of predation on the highly endangered Lower Keys Marsh Rabbit and Key Largo woodrat and the effects of predator removal (raccoons) on the viability of beach-nesting birds and sea turtles along the Outer Banks.   Additional work focuses on the potential impacts of offshore energy development on wildlife. He has directed the development of the Atlantic seabird compendium, an historical, digital clearing house for compiling scientific survey that documents the occurrence of seabirds on the continental shelf between Maine and Florida, developed guidelines for statistical-based sampling of  marine bird populations, and distribution models of seabird species to assess the impacts of proposed offshore wind energy facilities.
