There were no indications that any species were lost and the average number of taxa per station remained steady. However, spatial heterogeneities in the community were reduced and species composition changed significantly. Some taxa widespread in 1966-67 declined while others expanded, with frequencies of occurrence of individual taxa changing by up to 71%. The whelks <i>Buccinum undatum</i> and <i>Colus</i> spp., the bivalves <i>Astarte</i> spp. and <i>Cyclocardia borealis</i>, the toad crabs <i>Hyas</i> spp., the sea urchin <i>Strongylocentrotus droebachiensis</i> and the brittle stars (Ophiurida) showed particular increases. Corresponding declines were seen in the boring sponges <i>Cliona</i> spp., the horse mussel <i>Modiolus modiolus</i>, the scallop <i>Chlamys islandica</i>, the fan worm <i>Pseudopotamilla reniformis</i> and the stalked tunicate <i>Boltenia ovifera</i>. Replacement of attached, fragile, epifaunal, filter-feeding taxa by a combination of motile scavengers, motile filter-feeders and robust, burrowing filter-feeders suggests that the primary cause of the temporal change was physical impacts by fishing gear, even though trawling and scallop dragging in the area were neither intense nor new developments. Secondary causes of change may have included other ecosystem effects of fishing (supply of discards and bait), a mass mortality of scallops and a range expansion of a bryozoan (<i>Flustra foliacea</i>).","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Multi-decadal changes in the megabenthos of the Bay of Fundy: the effects of fishing","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"marine benthos; fishing impacts; biological traits; long-term change;benthic communities","OtherDescriptors":null,"Notes":null,"AnaPub":2007,"MonPub":null,"DateUpdate":"2018-05-17","DateCreate":"2007-10-25","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000250647200005","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.seares.2007.04.001"},"refs":null,"anarec":{"AnaID":115962,"PubliDate":2007,"Pagination":"220-240","XtraPublOfAnaID":null,"ISBN":null,"Volume":"58","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43261,"SerRR":"Journal of Sea Research.
