We review available data on distribution and community ecology to assess the functional role of <i>Idotea</i>in the Baltic Sea and how global change may affect essential ecological interactions. Data from the last 150 years suggest an on-going shift southward for <i>I. chelipes</i> and <i>I. granulosa</i> that may be caused by a changing climate. Several studies report local extinctions and mass abundances, which may be caused by a changing food web from over-fishing and eutrophication. The three species of <i>Idotea</i> have clear habitat segregation in the Baltic Sea, where salinity, temperature and vegetation are the main dimensions. <i>Idotea</i> spp. have a central role as grazers and in communities dominated by the perennial macrophytes <i>Fucus</i> spp. and <i>Zostera marina</i> and attain impressive feeding rates on a range of epiphytes/filamentous algae (top-down effect). <i>Idotea</i> can have both a direct negative grazing effect on macrophytes but also an indirect positive effect by removing epiphytes. The relative role of nutritional value and chemical defence for food preference is yet unclear for <i>Idotea</i>. Baltic idoteids are also important prey for several fish (bottom-up effect) and fish predation may have increased following overfishing of piscivorous fish. It is concluded that <i>Idotea</i> is a key taxon in the Baltic Sea food web, where guilds often contain few dominant species. Changes in population dynamics of <i>Idotea</i>, as a function of human generated global change, may have large-scale consequences for ecosystem functions in a future Baltic Sea, e.g. the extent of vegetation cover in the coastal zone.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Ecology and distribution of the isopod genus <i>Idotea</i> in the Baltic Sea: key species in a changing environment <i>Litopenaeus</i> and <i>Rimapenaeus Byrdi</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-05 01:31:09.596206","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Baltic Sea, distribution patterns, environmental changes, Idotea, key species","OtherDescriptors":null,"Notes":null,"AnaPub":2012,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2017-08-08","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000304839800003","VABBcode":null,"OpenAcc":1,"DOI":"10.1163/193724012x626485"},"refs":null,"anarec":{"AnaID":287728,"PubliDate":2012,"Pagination":"359-389","XtraPublOfAnaID":null,"ISBN":null,"Volume":"32","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43037,"SerRR":"Journal of Crustacean Biology.
