“…Changes in benthic community structure and functional diversity after 1988 were found for the entire North Sea (Neumann et al, 2008(Neumann et al, , 2009Neumann and Kröncke, 2011;Schückel et al, 2010;Kröncke, 2011;Kröncke et al, 2011). The RS 1988/1989 was detectable in 39 variables in the North Sea (Schlüter et al, 2008) and in 52 biotic and abiotic variables in the Baltic Sea (Möllmann et al, 2009).…”

“…Recently, the angular crab G. rhomboides extended its distribution from the eastern Atlantic to the southern North Sea (Neumann et al 2010) and also southern fish species such as the tub gurnard Trigla lucerna, the red mullet Mullus surmuletus and the pilchard Sardina pilchardus were now regularly found in the German Bight (Ehrich and Stransky 2001;Beare et al 2004;Ehrich et al 2007). In contrast, Kröncke et al (2011) found no indications for range expansions of non-native benthic infauna species by a comparison of infauna communities between 1986 and 2000 on a North Sea wide scale. So far, these climate-related effects influenced only single species rather than communities as a whole.…”

“…Kröncke et al (2011) found no fundamental shifts for benthic infauna communities in the last decades on North Sea wide scale even if single species such as N. nitidosa slightly shifted their core distribution. This seems to be true also for the German EEZ, because Rachor and Nehmer (2003) found similar patterns to those described by Salzwedel et al (1985) in the 1980s and Hagmeier (1925) in 1920s, indicating that no considerable and permanent changes of infauna community structure occurred over a period of almost 80 years.…”

“…So far, these climate-related effects influenced only single species rather than communities as a whole. Additionally, climate change effects were rather expressed as changes in abundance of species in the EEZ habitats, which were, for example, related to temperature-mediated increase in primary production and, thus, food supply for benthos (Kröncke et al 1998;Neumann et al 2009;Kröncke et al 2011). However, the coastal habitat was more sensitive to climate-related temperature changes compared to the more stable and stratified habitats Oysterground and Duck's Bill.…”

“…Daan et al (1990) highlighted the importance to analyse fish communities instead of single commercial species to understand how the North Sea ecosystem functions. Since the beginning of such investigations, effort increased to analyse spatial community structure of fish (Greenstreet and Hall 1996;Ehrich et al 2009), benthic infauna (Duineveld et al 1991;Heip et al 1992;Künitzer et al 1992;Kröncke et al 2011) and benthic epifauna (Frauenheim et al 1989;Jennings et al 1999;Zühlke et al 2001) on a North Sea wide scale. However, similarities and the interrelationships in community structure between these faunal components were only recently studied, for example by Callaway et al (2002) and Reiss et al (2010).…”

We compiled data from different monitoring surveys to analyse and compare community and diversity patterns of fish, epi-and infauna in the German Exclusive Economic Zone (EEZ) of the North Sea in order to identify benthic habitats common to all faunal components. We found congruent community patterns of fish, epi-and infauna for the coastal waters, the Oysterground and the area called ''Duck's Bill'', which coincided with specific abiotic characteristics of these regions. The three regions were defined as special habitats for fish, epi-and infauna species in the German EEZ. The differences in the seasonal variability of abiotic factors seem to be the most important discriminating abiotic characteristic for the three habitats. The spatial distribution of fish, epifauna and infauna communities remained stable over time although habitat characteristics such as sea surface temperature increased due to climate change. However, it is expected that the coastal habitat will be more sensitive to future climate change effects in contrast to the Oysterground and Duck's Bill habitat.

1. Taxonomic and functional trajectories of benthic assemblages were studied in shallow soft-bottom sediments in the bay of Saint-Brieuc (Western English Channel). Changes were assessed at different spatial and temporal scales using a macrobenthic dataset based on 38 stations sampled in 1987 and 2019, coupled with data from one station sampled annually between 2005 and 2019 as part of the European Water Framework Directive monitoring programme. 2. Taxonomic trajectories indicated 1) changes in the structure and distribution of benthic assemblages, 2) an homogenization of the assemblages, and 3) significant functional shifts. 3. Fishing activities and nutrient enrichment are probably strong drivers of the observed changes, as suggested by the higher mortality rate of fragile, flexible, tubiculous and burrowing species, and the increase in the abundance of opportunistic species in the assemblages. Certain populations of macroinvertebrates seem jointly controlled by climate change and by the aforementioned local factors of disturbance. 4. The Community Trajectory Analysis framework appears as a new and interesting method to track ecological changes in marine ecosystems by measuring change with respect to a baseline state, to help define ecological recovery (station returning to the initial ecological state) and departure (station presenting increased changes over time), and to analyse trajectory similarity. 5. According to the degradation of habitat over time, we identify the need for the implementation of knowledge-based conservation strategies, especially within Natura 2000 sites.
