Arctic biodiversity change and its consequences: Assessing, monitoring and predicting the effects of ecosystem tipping cascades on marine ecosystem services and dependent human systems

Description du projet

Des méthodologies et des concepts novateurs pour la surveillance de l’Arctique

De la fonte progressive de la glace de mer aux augmentations de la température, le changement climatique touche l’écosystème de l’Arctique. Il est important de prédire ces changements, mais la tâche s’avère ardue en raison de lacunes en termes de connaissances. Le projet ECOTIP, financé par l’UE, améliorera notre compréhension des causes, des seuils et des conséquences de la chaîne de basculements climatiques, ainsi que de ses effets sur la biodiversité marine de l’Arctique. Il intégrera des observations biologiques au sein d’une approche basée sur les caractéristiques de la biodiversité marine, et utilisera cette approche pour relier les changements des communautés biologiques aux fonctions de l’écosystème. Il cartographiera également la biodiversité passée et actuelle de l’Arctique et sa réponse à des facteurs externes. En impliquant des sociétés indigènes et des citoyens européens, le projet ECOTIP fournira des recommandations pour l’optimisation de la surveillance de la biodiversité et des services d’écosystèmes de l’Arctique.

Objectif

The Arctic marine environment is under rapid change, both in its physical and biotic conditions. The gradual loss of sea ice, increase in temperature, invasive species and compounding effects of additional ecosystem stressors are identified as likely causes of the observed turnover of Arctic species. Other issues of concern are the climatic tipping elements that are known to have affected the region in the geologic past, and that could well affect the region in the future, precipitating a regime shift of unprecedented magnitude. Predicting these changes in the Arctic ecosystem is hindered by several knowledge gaps, particularly in terms of mechanistic understanding of the coupling between drivers and responses. At stake are two important marine ecosystem services that human societies rely on; carbon sequestration with its feedback to global climate, and fisheries production that is the economic lifeblood of many of the local societies of the Arctic. ECOTIP will map out past and present Arctic biodiversity and its response to external drivers, and the effects of expanding commercial activities in the Arctic under expected climate change. It will investigate the resistance, resilience and persistence of key ecosystem components to multiple anthropogenic stressors, and estimate their potential tipping dynamics. It will use a trait-based approach in process studies, empirical analysis and numerical models as a novel means of quantifying functional diversity to predict how different anthropogenic forcing scenarios (including climate, invasive species, pollution, exploitation) change biodiversity, productivity and ecosystem services. ECOTIP will engage with indigenous societies and European citizens to provide recommendations for optimizing the monitoring of Arctic biodiversity and ecosystem services, identify adaptation strategies, promote international collaboration and support Europe's endeavors to implement the Paris Agreement and Sustainable Development Goals.
