New NSF grant awarded for ecosystem impacts of forest insects & pathogens

Starting in January 2017, the Matthes EcoLab will be funded by the NSF MacroSystems program for the project, “MSB-ECA: A generalized framework for modeling the impacts of forest insects and pathogens in the Earth System”. Forest insects and pathogens are global agents of ecosystem disturbance. In the United States, tree stress and mortality from insectsContinue reading “New NSF grant awarded for ecosystem impacts of forest insects & pathogens”

Summer research in the Matthes EcoLab

Summer research is in full swing in the Matthes EcoLab at Wellesley College. Amanda Hernandez ’18 and Prapti Koirala ’19 have been collaborating with Jackie, Fiona, and Ashley through the Science Center Summer Research Program to conduct a precipitation manipulation experiment on soil mesocosms. Our experiment tests the hypothesis that soil microbes adapted to dryContinue reading “Summer research in the Matthes EcoLab”

New paper comparing CMIP5 models to data on pre-EuroAmerican vegetation

Matthes led a new article published in JGR-Biogeosciences that compared plant functional types (PFTs) within the CMIP5 pre-industrial control modeling experiment to reconstructed data just prior to major land-use changes from EuroAmerican settlement. This analysis demonstrated that many CMIP5 models inaccurately map PFTs at the start of the industrial era, which can lead to biasesContinue reading “New paper comparing CMIP5 models to data on pre-EuroAmerican vegetation”

Wetland CH4 flux article published in JGR – Biogeosciences

A new article led by Cove Sturtevant and co-authored by Matthes was published in the Journal of Geophysical Research – Biogeosciences. This article used wavelets and information theory to investigate the temporal drivers of methane flux from two restored wetlands: one old wetland restored in 1997 and one new wetland restored in 2010. This analysis provided newContinue reading “Wetland CH4 flux article published in JGR – Biogeosciences”
