Terryanne Maenza-Gmelch

Senior Lecturer in Environmental Science
Director of the Environmental Science Laboratory

Terryanne Maenza-Gmelch  is a senior lecturer at Barnard College in the Department of Environmental Science.  She teaches Land-use, Bird and Plant Dynamics,  Introduction to Environmental Science (fall semester), Forests and Environmental Change, and Environmental Science Lab.   Her Ph.D. is from NYU.

Terryanne is a palynologist and forest ecologist. Her research and teaching interests include paleoecology, effects of climate and land-use change on bird populations, soundscape ecology and digital curriculum development. Her publications have focused on the Late-glacial and Holocene vegetation, climate, and fire of the Hudson Highlands, southeastern New York as well as other sites in the Northeast USA. Other research includes habitat-based bird surveying in Black Rock Forest in order to establish long-term trends, seasonal inventories and connections between bird diversity and vegetation composition and structure.  She has collaborated with the Macaulay Library of the Cornell Laboratory of Ornithology in an effort to archive audio of habitat soundscapes and individual bird taxa at Black Rock Forest.

Dr. Maenza-Gmelch  has developed and taught field-based ecology and environmental science courses for undergraduate,  graduate and high school students for several  years.   She teaches field courses at Black Rock Forest where she developed the curriculum for and taught the first residential undergraduate course at the forest. This was followed by a graduate course in field botany and forest ecology.

Terryanne collaborated with Columbia’s CNMTL to create the Paleomodule for the Virtual Forest Initiative (http://blackrock.ccnmtl.columbia.edu/paleoecology/).  The Paleoecology Module is a web-based,  interactive and inquiry-based virtual palynological experience. The fundamental idea was to take the pollen, plant macrofossil, and radiocarbon data from the actual Sutherland Pond sediment core and put them into a simulation so that students could learn the discovery process inherent in reconstructing a forest's ecosystem using paleoecological techniques without the time and resource constraints that make actual sediment coring and pollen processing impossible in a classroom setting.
