SCAR EXCOM 2013 WP11: Report on AnT-ERA (Antarctic Thresholds - Ecosystem Resilience and Adaptation)
Title: Antarctic Thresholds - Ecosystem Resilience and Adaptation (AnT-ERA)
Author: Julian Gutt
Stresses on Antarctic ecosystems result from global climate change, including extreme events, and from other human impacts. Consequently, Antarctic ecosystems are changing, some at a rapid pace while others are relatively stable. A cascade of responses from molecular through organismic to the community level are expected.
The differences in biological complexity and evolutionary histories between the polar regions and the rest of the planet suggest that stresses on polar ecosystem function may have fundamentally different outcomes from those at lower latitudes. Polar ecosystem processes are therefore key to informing wider ecological debate about the nature of stability and potential changes across the biosphere.
The main goal of AnT-ERA is to facilitate the science required to examine changes in biological processes, from the molecular to the ecosystem level, in Antarctic and Sub-Antarctic marine, freshwater and terrestrial ecosystems. Tolerance limits as well as thresholds, resistance and resilience to environmental change will be determined.
AnT-ERA will be classified into 3 overlapping themes: (1) molecular and physiological performance, (2) population processes, (3) ecosystem functions and services.
As a SCAR program AnT-ERA lives from the contributions of the scientific community, the national programs and closely linked third party funded projects. Thus, we need full support in promoting AnT-ERA through the SCAR Delegates.
Exchange of experience and ideas within a truly global scientific community.
Exchange of experience and ideas independent of competition for research funds.
Expected major Outcomes and Milestones:
Integration of early career scientists and new national programs.
Support of scientific publications, especially reviews.
Dissemination of results.
Communication between and coordination of research activities including trans-disciplinary projects.
Action recommendations especially in the context of natural variability and anthropogenic environmental change.
Contributions to overarching reports, especially "Antarctic Climate Change and the Environment".
Presentations at influential Antarctic-specific symposia.
Presentation of results to the broader scientific community.
Leading of, and participating in, major workshops, which support both the development of long-term observation networks (weather, ocean, lakes and streams or terrestrial) and an integration of ecological information into interdisciplinary models.
Providing mini-grants for early career scientists, members of newly emerging national programmes and contributors to reviews for traveling.
The following events mark potential milestones in communication within the AnT-ERA community and will provide a platform for exchange with a broader scientific world:
2012 Begin implementation of specific science, management and outreach plans
2013 Kick-off AnT-ERA workshop at the XI Biology Symposium, Barcelona
2014 Mini joint AnT-ERA – ICED workshop at the XXXIII SCAR and Open Science Conference
2015 AnT-ERA workshop: capacity building to train the next generation of specialists for biological process studies
2016 Joint AnT-ERA - AntEco - AntClim21 Syntheses-workshop at the XXXIV SCAR and Open Science Conference
2017 Meeting to structure and draft reviews for each scientific level
2019 Meeting to plan the future of AnT-ERA
2020 Final workshop (SCAR OSC).
