Ecological processes and adaptation
Analyzing climatic and oceanographic data to understand ecological processes and emerging ecosystem patterns
The people working with this cluster are ecologists specially trained to study how climate and fishing influence marine ecosystems. A particular challenge is understanding the combined effects of climate and fishing, as the effects of fishing depend on the state of the climate. For example, climate may change the structure of the ecosystem and thereby its dynamics. In this cluster we will develop new data driven statistical models and expand on previous methods in order to better understand how changes in ecosystem structure (e.g., species distributions, size composition, seasonality) are linked to changes in ecosystem functioning [e.g., in trophic interactions, alterations between bottom-up (resource-driven) and top-down (consumer-driven) control, fish productivity].
As part of his work as PD1, Joël Durant will:
1. Explore the competition between fishing and top predators (e.g., cod) for small pelagic fish
2. With PD2, explore the threshold effect of external forcing (e.g. temperature) on ecosystem dynamics
3. With PD4, assess the effects of ice-melting on ocean climate and the marine foodweb
As part of his work as PD1, Leif Chr. Stige will:
1. With K. Kvile, explore how climate and fish influence the spatial, seasonal and size distribution of zooplankton
2. With PD2, explore the role of the plankton as possible causes for nonlinear and nonstationary dynamics of fish stocks
3. Collaborate with PD 5 in comparative study of Nordic fisheries
As part of his work as PD2 Marcos Llope will study threshold effects on three ecosystems:
1. The Icelandic Seas. The idea of threshold dependent dynamics in the seas around Iceland has not been explored yet. In collaboration with MARICE we will investigate if the regime shift conceptual framework is suitable to model time series from this ecosystem.
- The Baltic Sea, building on previous studies done in collaboration with the Stockholm Resilience Centre we will further develop simulations of this ecosystem in order to test for early warnings.
- The Barents Sea, in collaboration with Joël Durant and Leif C. Stige we will explore non stationary responses of fish stocks in relation to climate and plankton.
