7 Barents Sea Ecosystem Resilience under global environmental change – January 2011 Resilience ? Variability Vulnerability Robustness Stability Diversity Complexity Resistance Adaptability

8 Barents Sea Ecosystem Resilience under global environmental change – January 2011 Resilience definition: Holling (1973): the ability to absorb disturbance and maintain function

9 Barents Sea Ecosystem Resilience under global environmental change – January 2011 Resilience of & to what? individuals populations communities ecosystems food supply, thermal environment, parasites and diseases,... recruitment, habitat, demographic structure loss/gain species altered phenologies altered spatial overlap energy input, species interactions (top-down, wasp-waist) functions? survival growth reproduction non-extinction interactions between species

10 Barents Sea Ecosystem Resilience under global environmental change – January 2011 evaluate the effects of global environmental change on the future structure and resilience of the Barents Sea ecosystem BarEcoRe

11 Barents Sea Ecosystem Resilience under global environmental change – January 2011 evaluate the effects of global environmental change on the future structure and resilience of the Barents Sea ecosystem quantitative data analysis and modelling climate and fishing- induced species comp, spatial structure, trophic network ability to absorb disturbance and maintain function BarEcoRe fish and benthos communities

12 Barents Sea Ecosystem Resilience under global environmental change – January 2011 Bar-EcoRe: The structure WP1: Community structure WP2: Trophic interactions WP3: Population distribution WP4: Resilience & Early warning

13 Barents Sea Ecosystem Resilience under global environmental change – January 2011 Bar-EcoRe: WP1 WP1: Community structure investigate past and present spatial and temporal variability in fish and benthos communities in the Barents Sea in relation to environmental variability in space and time past community structure & control processes

14 Barents Sea Ecosystem Resilience under global environmental change – January 2011 Bar-EcoRe: WP2 WP1: Community structure WP2: Trophic interactions investigate how climate variation propagates through the Barents Sea ecosystem through changes in species interactions trophic transfer spatial coupling impact of increased T°

15 Barents Sea Ecosystem Resilience under global environmental change – January 2011 Bar-EcoRe: WP3 WP1: Community structure WP2: Trophic interactions WP3: Population distribution latitude longitude investigate the effects of past climate / human pressure on the spatial distribution of Barents Sea plankton, benthos and fish populations. multi-species spatial distribution models and maps

16 Barents Sea Ecosystem Resilience under global environmental change – January 2011 Bar-EcoRe: WP4 WP1: Community structure WP2: Trophic interactions WP3: Population distribution WP4: Resilience & Early warning investigate how organismal, population and community properties influence Barents Sea ecosystem resilience and assess/forecast changes in resilience associated with climate change and fisheries INDICATORS of species resilience community resilience early warning signals
