Abstract
Coastal ecosystems worldwide face increasing anthropogenic pressures, with implications for the local ecological status and biodiversity. Using a temperate coastal ecosystem in poor ecological condition, this study revealed the importance of blue mussel (Mytilus spp.) reefs in supporting mobile marine fauna (e.g., fish). Using baited remote underwater video systems (BRUVS), we compared mobile marine fauna associated with A) high coverage mussel reefs in shallow and deeper parts of the area and B) corresponding low coverage soft-bottom sites. Our BRUVS findings demonstrate that blue mussel reefs harbor a higher taxonomic diversity of mobile fauna compared to the corresponding soft-bottom sites. Furthermore, the species community associated with mussel reefs exhibits distinct composition from the soft-bottom sites. Despite efforts to mitigate harmful eutrophication, the poor ecological status of the coastal ecosystem highlights ongoing challenges in coastal management. Our results have important implications for management of coastal resources and conservation of marine biodiversity. Despite its environmental challenges, the examined ecosystem serves as a representative case for many temperate waterbodies emphasizing the need for improved management outcomes. Incorporating mussel reef conservation and restoration into temperate water body management actions could enhance ecosystem resilience and local biodiversity in many coastal ecosystems subjected to anthropogenic pressures.
期刊介绍:
The Journal of Sea Research is an international and multidisciplinary periodical on marine research, with an emphasis on the functioning of marine ecosystems in coastal and shelf seas, including intertidal, estuarine and brackish environments. As several subdisciplines add to this aim, manuscripts are welcome from the fields of marine biology, marine chemistry, marine sedimentology and physical oceanography, provided they add to the understanding of ecosystem processes.
