Dr. Marc Macias-Fauria

James Martin Research Fellow

Current Research & Academic Profile

I am a (mostly plant) ecologist with a special focus on cold environments.
My research is directed at understanding the interactions between physical and biological systems over a wide range of spatial and temporal scales. Ecological processes are coupled with physical mechanisms such as atmospheric/ocean dynamics and/or geomorphology, among others (i.e. ecology is largely controlled or constrained by the physical environment).
With the aim of understanding ecological and biogeographic processes such as species range shifts through local extinction and migration, I focus on the use and interpretation of long-term ecological records (e.g. fossil pollen, tree-rings, macrofossils) and modelling.
I gained a degree in Biology at the University of Barcelona, an M.Sc. at the Department of Biological Sciences of the University of Calgary, and a Ph.D. at the Department of Geology (now Department of Geosciences and Geography) of the University of Helsinki, where I studied the coupling of forest wildfires, tree-growth, and insect outbreaks with climate.
