EcoChange – Ecosystem dynamics in the Baltic Sea in a changing climate
Climate changes threaten to accentuate the problems with eutrophication and overfishing in the Baltic Sea, leading to ecosystem changes of hitherto unprecedented magnitudes. The research programme EcoChange deals with the ecological consequences of climate changes on the Baltic Sea, and how the Baltic Sea will respond.
Climate change will make the marine food web less efficient, and toxic substances will increase in fish and other organisms. This became clear during the first phase of EcoChange, and now it´s time to dig deeper into these questions. “A large part of our work concerns what the effects of the loss in food web efficiency leads to” says Agneta Andersson, professor in marine ecology at Umeå University and coordinator for EcoChange.
Persistent organic pollutants, POPs, can be harmful to living organisms even in low concentrations. They are stable and persistent, and can be found far away from their sources. Until recently the systematic monitoring of these substances has been done mainly in air. Focus is now gradually moving towards aquatic environments, and the first worldwide passive sampling campaign of POPs in oceans and fresh water was initiated in 2017. A group of EcoChange researchers from Umeå University will take part in the global network.

PhD student Javi Alegria
The EcoChangegroup in Kalmar has recruited Javi Alegria from Spain as a PhD student.
He will be studying how increased nutrient availability, as consequence of climate change, will affect the phytoplankton communities. Phytoplankton are in the base of the trophic chain, so effects on them are expected to have effects on the rest of the ecosystem.
