Mr. Robert L. Johnson Mr. Robert L. Johnson
Manager of Cornell Research Ponds - Research Support Specialist, EEB,          Cornell  University     
Email: rlj5@cornell.edu
Phone: at Ponds (607) 257-2064, at Muenscher Lab (607) 255-1076
Mail: E140 Corson Hall, Cornell University, Ithaca, NY 14853

Research Interests
Bob is the manager of the Cornell Ponds, and as such, is involved with most projects here. His own research primarily involves the physical, chemical, and biological management of aquatic plant communities, and is a noted expert on the invasive Eurasian watermilfoil, and its most potential biocontrol agents: Acentria ephemerella, a naturalized aquatic moth, and Euhrychiopsis lecontei, a native weevil. Current projects involve (1) the rearing, augmentation and monitoring of milfoil biocontrol agents, (2) examining what factors influence invertebrate herbivore populations, (3) monitoring the seasonal 3-D structure of aquatic plant communities for the Lake Ontario Biocomplexity Project and in other lakes throughout the Northeast, and (4) leading projects demonstrating milfoil herbivore use in the Finger Lakes, and on biocontrol of water chestnut.

Dr. Nelson Hairston Dr. Nelson Hairston, Frank H. T. Rhodes Professor of Environmental Science
Chair of Department of Ecology and Evolutionary Biology (EEB), Cornell
Email: ngh1@cornell.edu
Phone: (607) 254-4201, or (607) 254-4231
Mail: E145A/E305 Corson Hall

Research Interests
Dr. Hairston studies microevolutionary processes, the role of population processes in community dynamics, and the interactions between community dynamics and ecosystem functioning. Virtually all of his research has been on inland-water organisms, especially zooplankton and fish. Click here for more information.


Paul H. Lord Paul H. Lord
Graduate Student, SUNY Oneonta Biological Field Station , and Cornell Ponds
Email: lordp@usa.net
Phone: (607) 257-2064
Mail: E140 Corson Hall, Cornell University, Ithaca, NY 14853

Research Interests
An avid diver and scuba instructor, Paul's research focuses on control of exotic macrophytes. He has discovered strong linkages between fish communities, herbivorous insect populations, and plant communities. He continues to lead projects on several Madison County lakes, as well as on Skaneateles, Otisco, and Chautauqua Lakes. Click here for more information.

Pete VanDusen Peter J. VanDusen
Research Technician, Cornell Ponds
Email: pjv2@cornell.edu

Research Interests
Pete has been instrumental in planning and leading both field operations and lab work at the ponds since 1995, and has been responsible for training and overseeing lab technicains at the ponds. He has broad interests in aquatic and fisheries ecology, and has worked on virtually all projects at the ponds over his tenure here, with some focus on monitoring of aquatic plant communities throughout NY and the autecology of biocontrol insects for Eurasian watermilfoil. His masters work dealt with the riparian logging impacts on stream macroinvertebrate and fish communities in Upper Michigan. He is now a fishery biologist for the Minnesota Department of Natural Resources, but remains active in data analysis for the ponds and maintains the ponds' webpages. Click here for more information.

Dr. David Winkler Dr. David Winkler
Professor, Dir. of Graduate Studies, Faculty Curator of Birds, EEB, Cornell
Email: dww4@cornell.edu
Phone: (607) 254-4216
Mail: E241 Corson Hall

Research Interests
Dr. Winkler is an ornithologist with strong interests in physiological, evolutionary and behavioral ecology. In his present work, he is exploring the evolution and implications of patterns of dispersal in birds, the genesis and significance of variation in individual quality, and the causes of temporal and spatial variation in the life histories of birds.

Dr. Anne Clark Dr. Anne Clark
Associate Professor, Dept. of Biol. Sci., SUNY Binghamton
Email: aclark@binghamton.edu
Phone: 607-777-6228

Research Interests
Dr. Clark works on questions of the evolution and development of social behavior, primarily in birds in both lab and field. She is particularly interested in individual variation in behavior. Current projects in the field include a) the social attraction of young female redwinged blackbirds to territories of older females, b) the evolution and social learning of predator/parasite recognition in redwinged blackbirds, c) the effect of sibling age and sex on behavior and success of nestling redwinged blackbirds, d) food choice and secondary toxin avoidance by parent house wrens feeding young and e) the role of siblings in early learning and survival of crows. In addition, she is studying the development and transmission of food preferences in budgerigars and, in collaboration with faculty at Cornell, the hormonal basis of female-female aggression in budgerigars (lab) and redwings (field).

Dr. Richard Root Dr. Richard Root
Professor, EEB, Cornell
Email: rbr1@cornell.edu
Phone: (607) 254-4237
Mail: E441A Corson Hall

Research Interests
Dr. Root uses the insect faunae associated with goldenrods, Solidago spp., and milkweeds, Asclepias spp., as representative systems for exploring questions relating to: (1) the impact of herbivores on plant performance and succession, (2) the structure and assembly of insect communities, (3) the relationships between body size, host range, feeding style, predator defense, and phylogeny, (4) contrasts in insect-plant interactions in forests, meadows, dunes, and fens, and (5) the functioning of complex webs of species interactions.

Dr. Elizabeth Gross Dr. Elizabeth Gross
University of Konstanz, Germany
Email: Elisabeth.Gross@uni-konstanz.de
Phone: +0049 (0)7531 88-3112 (Germany)
Mail: Fachbereich Biologie, Limnologisches Institut, Postfach M659, Universitšt Konstanz, D-78457 Konstanz, Germany

Research Interests
Dr. Gross studies allelochemical interactions of submersed macrophytes with other primary producers and macroinvertebrate herbivores. She pursues functional studies of the mechanisms involved in these interactions and combines those with field observations. Dr. Gross now leads a massive aquatic research program on L. Constance, Germany. Click here for more information.

Mr. Thomas Vawter Mr. A. Thomas Vawter
