Even modest climate change may lead to major transitions in boreal forests
August 10, 2022
Roy published a paper in Nature on the impacts of warming in southern boreal forests!
“The sensitivity of forests to near-term warming and associated precipitation shifts remains uncertain. Herein, using a 5-year open-air experiment in southern boreal forest, we show divergent responses to modest climate alteration among juveniles of nine co-occurring North American tree species.”

Considering coasts: Adapting terrestrial models to characterize coastal wetland ecosystems
June 15, 2021
Genevieve, Roy, and Pat published modified E3SM models to mimic tidal marsh dynamics and SMARTX findings in Ecological Modeling!
“The Energy Exascale Earth System Model (E3SM) simulates fully coupled processes and interactions among water, energy, carbon and nutrient cycles. E3SM connects vegetation and soil dynamics through nutrient uptake, plant production, litterfall and decomposition as a function of abiotic parameters (e.g. temperature and moisture). However, E3SM is designed to characterize terrestrial ecosystems and connects land and open ocean systems using a single streamflow transport term, ignoring the complex dynamics of energy, water, carbon, and nutrients in coastal systems. The goals of our project were to: (1) Parameterize a point version of E3SM to capture coastal wetland habitats and (2) Determine marsh community responses to increased temperature and elevated CO2.”

Biogeochemical and plant trait mechanisms drive enhanced methane emissions in response to whole-ecosystem warming
April 19, 2021
Genevieve and Pat published findings from SMARTX in Biogeosciences!
“Climate warming perturbs ecosystem carbon (C) cycling, causing both positive and negative feedbacks on greenhouse gas emissions. In 2016, we began a tidal marsh field experiment in two vegetation communities to investigate the mechanisms by which whole-ecosystem warming alters C gain, via plant-driven sequestration in soils, and C loss, primarily via methane (CH4) emissions. Here, we report the results from the first 4 years.”

Synergistic effects of four climate change drivers on terrestrial carbon cycling
November 23, 2020
Roy published a paper in Nature Geoscience with TeRaCON collaborators!
"Disentangling impacts of multiple global changes on terrestrial carbon cycling is important, both in its own right and because such impacts can dampen or accelerate increases in atmospheric CO2 concentration. Here we report on an eight-year grassland experiment, TeRaCON, in Minnesota, United States, that factorially manipulated four drivers: temperature, rainfall, CO2 and nitrogen deposition.”

Automated methane chambers designed by Roy and Genevieve have become the newest addition to the Global Change Research Wetland! Twelve methane chambers were deployed as a part of GENX to capture methane data at short time scales, including methane changes in response to precipitation, tidal cycles, and other weather events.
