In the last decades we have witnessed a precipitous decline in Arctic sea ice extent, volume, and concentration. This process lies at the centre of the increasing attention societies worldwide are giving to the Arctic, as it imposes a fundamental new physical arrangement of the region with consequences on climate, ecology, societies, economies, and politics, locally and beyond.
Whereas it appears obvious that sea-ice adapted arctic biota – both land-based and maritime – will be impacted by such changes, the scarcity of high quality, long-term, and geographically representative observations about many Arctic biological systems challenges our understanding and ability to forecast the future of many arctic ecosystems under these new conditions.
This talk will discuss the ways in which current research addresses such questions, reflecting on the current state of our knowledge about the response of arctic ecosystems to sea ice decline.
Marc Macias-Fauria is a NERC Fellow and associate professor at the School of Geography and the Environment, University of Oxford. He is an ecologist with a special focus on cold environments, and his research is directed at understanding the coupling between physical and biological systems over a wide range of spatial and temporal scales. With the aim of understanding ecological and biogeographic processes, he focuses on the use and interpretation of long-term and palaeo-ecological records (e.g. fossil pollen, tree-rings, macrofossils), and modeling.
Marc gained a degree in Biology at the University of Barcelona, a master of science degree at the Department of Biological Sciences, University of Calgary, and a doctor of philosophy degree at the Department of Geology (now Department of Geosciences and Geography) of the University of Helsinki, before moving to Oxford in 2011.
