Roser Matamala

Terrestrial ecologist
- Biosciences

Roser Matamala is a terrestrial ecologist specializing in biogeochemistry and global change research. She addresses changes in ecological processes, climate and land-use through the use of stable isotope methods and micrometeorological techniques.

Roser has more than 20 years of research experience studying the biogeochemistry of ecosystems and is particularly interested in the carbon cycle. She uses an integrative systems approach to study the cycling of carbon through the atmosphere, plant, soils and microorganisms as they interact and respond to environmental factors. Additionally, Roser is interested in quantifying the contribution of plants and microbial communities to ecosystem carbon fluxes and changes in soil carbon stocks. She currently is the Principal Investigator of two AmeriFlux research sites located at Fermi National Accelerator Laboratory. These sites provide continuous observations of ecosystem level exchanges of CO₂, water and energy for an agricultural field and a restored prairie.

Roser's past research has focused on a number of major projects investigating elevated atmospheric CO₂ effects on ecosystems over several different types of biomes, including wetlands, forests, grasslands and agricultural sites on temperate systems. Her current research has taken her into the Arctic, including the exploration of tundra and permafrost areas of Alaska, where she is investigating changes in soil carbon stocks due to global climate change.
