Academic Profile

Professor Marc Macias-Fauria is an ecologist who focuses on cold environments. His research is mostly directed at understanding the coupling of physical and biological systems (biogeoscience). He employs long-term ecological records and modelling to understand ecological and biogeographic processes as they are constrained by the physical environment.

He gained a degree in Biology at the University of Barcelona, an MSc at the Department of Biological Sciences, University of Calgary, and a PhD at the Department of Geology (now Department of Geosciences & Geography), University of Helsinki, where he studied the climate controls on boreal forest wildfires, tree-growth, and insect outbreaks.

Current Research

Biogeoscience Lab

We study the coupling between physical (abiotic) and biological processes. Our approach is:

  • Strongly process-based, employing empirical data, mathematical, and statistical modelling;
  • Interdisciplinary: approaches from geosciences, climatology, biology, physical geography;
  • Biased towards cold ecosystems (arctic and alpine);
  • Focused on long-term ecology: time-scales that span decades to millennia (palaeoecology); and
  • Strongly field-based.

Research Areas

Spatial Ecology

Study of ecological systems in a spatially explicit and comprehensive manner. Remote sensing technologies -from Unmanned Aerial Vehicles (drones) to space-borne sensors onboard satellites- allow for an unprecedented spatial detail in the analysis of biodiversity responses to environmental change. Together with big data and high-performance computing, this approach holds promise in basic ecological theory and applied conservation.

Ecological Interactions

The impact of animal activity on the responses of vegetation to climate has been considered minimal at the regional-to-global scales: e.g., animals do not feature in most Earth System Models. However, the effects of animals on vegetation - in what are known as top-down effects - are only beginning to be understood. I focus on the potential for large mammal herbivory to modulate the response of vegetation to climate change. My approach focuses on the Arctic tundra and deals with observational data from heavily grazed areas and proxy palaeo-ecological data starting in the last interglacial, ~125k years ago. This research is relevant for future discussion on Nature-based solutions, rewilding, and the field of biodiversity conservation.

Vegetation Resilience to Climate Change

We seek to better understand the strategies that enable plants to survive during long periods of unsuitable conditions, with a focus on the high latitudes. This largely overlooked ability will enable to better understand the resilience and/or persistence of ecological systems and has the potential to substantially modify the inferred trajectories of ecosystems during the Quaternary. Such investigations are now possible due to advances in molecular ecology -most notably environmental ancient DNA, which provide evidence at unprecedented spatial, temporal, and taxonomical grains.

Sea Ice Ecology

We tackle questions related to the effects of Arctic sea ice on climatic and ecological processes, both during the observational record and in the past millennia.

Arctic Holocene Biodiversity

We study Arctic biota/environment relationships at centennial to millennial temporal scales, with the aim to inform current Arctic biodiversity and generate multiple projects in the next decade.
