The Palaeo-Resilience Working Group - Workshop 1: Measuring Components of Resilience in Long-term Ecological Datasets

Tildelt: kr 59 999

Identifying the properties that underpin ecosystem resilience in response to climate change and other disturbances is a global research priority. The Convention on Biological Diversity (Target 15) states: "by 2020, ecosystem resilience and the contribution of biodiversity to carbon stocks have been enhanced through conservation and restoration". Yet despite its importance, there is no single approach that can be used to measure ecological resilience globally. Depending on the study system and context, different components of resilience can be identified. Recent attempts used satellite data to map components of resilience at global scales. However, these ecological 'snapshots' are based on measuring short-term ecological responses, and whether the patterns reflect fundamental properties of the systems, or are a result of historical disturbance legacies remains unknown. The biological and geochemical information preserved in sediments provide a unique opportunity to identify the long-term dynamics processes related to resilience in terrestrial systems, but a current knowledge gap exists to develop metrics for comparing the key components of resilience both within and between ecosystems. This workshop will bridge this gap by developing a set of standardised, quantitative approaches for comparing components of resilience across biomes using long-term ecological data. We will develop two parallel methods designed to measure and test components of ecological resilience to climate and other disturbances, and use ecological datasets covering a range of timescales to validate these approaches. The workshop contributes to phase 1 of a major international working group, and the results have broad implications for understanding the patterns and causes of resilience across landscapes.
