Welcome to the Novick Lab

Eco-physiology and Bio-meteorology at Indiana University

We study

interactions and feedbacks between terrestrial ecosystems and the atmosphere.

Our Work...

is focused on understanding the links between climate, land management, and ecosystem carbon and water cycling. Our work blends original field data, network observations, and models. Ultimately, our goal is to better predict future climate conditions, and their associated impacts on US agro-ecosystems.

Research Projects


Long-term monitoring of land atmosphere exchange of CO2, H2O, and energy

Terrestrial ecosystems are important regulators of atmospheric CO2 concentration, water cycling, and surface and air temperature. In the Eastern U.S., the movement of CO2, H2O, and heat energy between forest ecosystems and the atmosphere can be quite large, but also quite sensitive to variable meteorological conditions. To improve our understanding of the magnitude and variability of these fluxes, our lab supports long-term observations of land-atmosphere mass and energy transport using "Flux Towers" like these:

Morgan-Monroe State Forest

Active Since 1998 - Central Indiana, USA
~90-year-old eastern deciduous hardwood forest

Linking forest cover and temperature in the Eastern United States

Reforestation of grasslands and croplands cools the earth's surface in the tropics, and warms the surface in boreal zones. However, the impact of reforestation on surface temperature in the temperate zone is unclear. This project will test the hypothesis that reforestation in the Eastern U.S. affects energy balance in ways that cool the surface and thus may obscure long-term warming from climate change. Just as human bodies are cooled by sweating or by a fan, forests may be cooled by greater rates of evapotranspiration and wind-driven movement of heat energy when compared to the croplands and grasslands they have replaced. Project outcomes will inform models that reproduce historic climate trends and predict future conditions with more confidence. The research will also inform the development of sustainable agro-ecosystem management strategies that mitigate damaging effects of drought on ecosystem productivity and function. Funding from this project comes from the National Science Foundation, Division of Environmental Biology, CAREER award program

Drought Impacts On Species-Specific Carbon Uptake And Growth In Eastern U.S. Hardwood Forests

Drought events, which are predicted to become more frequent in the future, threaten to disrupt U.S. forest carbon cycling with important ecological and economic impacts. Thus, there is an imperative to obtain a species-specific understanding of the mechanisms determining tree response to drought. Our proposed work will meet this challenge by leveraging a rich collection of eco-physiological data collected from multiple eastern U.S. deciduous forest sites during a severe, naturally occurring drought. These data will be combined with new observations from a proposed rainfall removal experiment, and information on historic forest carbon cycling to be obtained from tree cores. Our focus on Eastern U.S. forests represents a departure from recent work investigating forest drought impacts in more arid regions; in the relatively wet Eastern U.S., drought-driven tree mortality may not be common, but the consequences of drought for forest carbon uptake and timber productivity may nonetheless be profound. Funding from this project comes from the USDA - Agriculture and Food Research Institute (AFRI).

Impacts of Land-Use/Land-Cover and Climate Changes on carbon cycling in the Southeastern USA

The southeastern US is characterized by high precipitation and solar radiation, making the region a major carbon sink and supporting vital food and fiber industries. Over the last two centuries, this region has experienced a remarkable disturbance history characterized by widespread clearcutting and then reforestation under active land management. Regional carbon cycling is undoubtedly linked to this management history, yet the mechanisms by which historical and future land management decisions determine the magnitude and variability of the regional carbon sink have not been elucidated. This project will merge information on regional ecosystem function from satellites, flux towers, and USDA Forest Service inventory data to better understand the carbon consequences of past, ongoing, and future land cover changes in the Eastern US. Funding from this project comes from the NASA-ROSES Carbon Cycle Science Program.
