John M. Farrell, Ph.D.
Associate Professor | TIBS Director

My interests revolve around the broad topic of aquatic ecology and management of aquatic resources. I am interested in understanding the structure and function of aquatic systems and applying that information to informed management applications. I have largely dedicated my research effort to investigate problems regarding the St. Lawrence River. This commitment involves important research on the effects of environmental change, both biotic and abiotic, and exploitation of fishery resources on a major north-temperate river ecosystem. My work on the St. Lawrence has focused on fish ecology and coastal wetland ecology. I have developed standardized monitoring databases of value in assessing nearshore and pelagic processes and fish population trends useful for assessing research needs and investigating change. My interest and concentration on fish and their habitats has led the program in many directions including early life history, population ecology, disease, species interactions, physiology and energetics, habitat restoration, and management.

Geofrey E. Eckerlin
Ph.D. Candidate

Geofrey E. Eckerlin started working in aquatic ecology while earning an AAS at SUNY Morrisville in Aquaculture and Aquatic Science (1999). Afterward, Geof studied Natural Resources Management at Cornell University (2001) and graduated to conducting fisheries research on the Hudson River and Lake Ontario with Cornell University (United States Geological Survey Cooperative Fisheries Unit, Natural Resources and the Center for the Environment) and the Hudson River National Estuarine Research Reserve.

Projects Geof spearheaded include a biological impact assessment in the post-9/11 NY-Harbor and a functional assessment of the submerged aquatic vegetation (SAV) over the length of the Hudson River. At TIBS, Geof is focusing on the interplay of the invasive round goby -highly abundant and susceptible to the invasive viral hemorrhagic septicemia virus (VHSv)- and the economically and socially important smallmouth bass population in the St. Lawrence. Smallmouth in the Great Lakes have discovered round goby as desirable food items and are thusly confronted with a tradeoff between an abundant protein source and risks incurred by high exposure to VHSv. This work is funded by New York Sea Grant and the Federal Aid in Sportfish Restoration Program administered by the New York State DEC.

Ben Amos
M.S. Candidate

Ben’s aquatic ecology career started with a B.S. in Wildlife and Fisheries Science from The Pennsylvania State University (2013).  His interests in the restoration and enhancement of native fishes lead him to graduate education at ESF with the opportunity to study large river ecology in the Thousand Islands. His research is focused on spawning habitat shifts in sport fish, notably northern pike, due to water level management on the St. Lawrence River.  Through trace element analysis of the otoliths (earstones) of spawning and juvenile fish, he hopes to determine how current water regulations are influencing spawning site selection.  He hopes his work will prove valuable in influencing future water regulation decisions.

Andrew Miano
M.S. Candidate

Andrew received his bachelor’s degree in biology from Connecticut College and is interested in the impacts from invasive species. His previous experience includes work as a research technician for the Marine Biological Laboratory studying Lake Trout and Arctic Grayling at the Toolik Lake Field Station, AK. At ESF his research focuses on how differences in spawning habitat influence Round Goby egg predation rates on Yellow Perch, Walleye, Northern Pike, and Muskellunge.

Mark Leopold
M.S. Candidate

Do fish population gonadal properties (e.g sex ratio, fecundity, testis and sperm density) differ among populations with differing stressors and history of management? Mark Leopold is examining these questions by comparing gonadal demographics among four northern pike populations in Northern New York including the St. Lawrence River. Can complex reproductive feedbacks occur in response to exploitation history? All Mark's sampling occurred during pre-spawning using ice-fishing techniques; preliminary findings show marked differences in sex-ratio with female dominance occurring in some populations and a near 50:50 ratio in others.

Kelly Huffman
M.S. Candidate (co-advised with Dr. Chris Whipps)

Kelly earned her bachelor’s degree in biology from Old Dominion University.Her research is focused on the genetic and experimental study of sex ratio in the northern pike population of the upper St. Lawrence River. Her previous experience includes work with invasive plant species in Whiskeytown National Recreation Area and sustainable agriculture practices in the United Kingdom and Czech Republic.
