To study how communities and their functionality changed over time and space, we include 16 stations, with eight located in sheltered and eight in exposed coastal zones. Each station was sampled between late spring and early summer in 1973, 1989, 2000 and 2013. All zoobenthos samples were collected with an Ekman-Birge grab sampler (289 cm2) taking five replicates per site and directly fixed in a 4% buffered formaldehyde solution. In the lab the organisms were identified to their lowest practical taxonomic level under a stereomicroscope. The applied exposure classification derives from an established exposure index for northern Baltic Sea coasts by Isæus (2004). The exposure-classification offers a habitat proxy for the exposure to waves and wind, depth and the proximity to land, which are important structuring components for biological communities. Hence, sheltered sites are generally shallower, closer to land and less influenced by wind and wave action compared to exposed sites.” [Extracted from Weigel et al., 2015]Citation(s)
