ecology of Arctic coasts Currently, global warming especially causes strong effects on Arctic ecosystems. We study the consequences of increasing water temperatures on species interactions in Arctic benthic [...] in financial support from the Interreg North-West Europe Programme. Exciting results Arctic burrowing Effects of Arctic lugworms Find out more Marine heatwaves Do you remember? Find out more Team PIs: Dr [...] benthic coastal communities. From these investigations we predict future scenarios for a warmer marine Arctic ecosystem and its species communites. Evolutionary Ecology Species invasions as a tool to study rapid

Understanding these processes – especially in the rapidly changing polar regions where the changes

Currents transport plastic debris through the ocean, allowing it to accumulate even in remote areas like the Arctic. Unlike beach debris, the plastics in the ocean cannot be readily removed – and breaks down [...] intense research have shown that garbage can be found throughout the world’s oceans. Even in the most remote parts of the ocean, like the polar regions or the bottom of the deep sea, we can find large amounts [...] element Where does plastic debris end up? A great deal of the debris in and on the ocean ends up on beaches or the ocean floor. Especially deep-sea trenches have essentially become deposition sites for large
