According to Elton's biodiversity and invasibility hypothesis, non-native species must be competitively superior to the resident species in order to successfully invade. An invader that is ecologically similar to a native species may cause intense interspecific competition as they both require the same resource. Furthermore, an increase in the density of an invading competitor may enhance the intensity of the competitive interaction, however, this may be reduced if the inferior competitor has a refuge that reduces the amount of time it is in direct contact with the superior competitor. In laboratory-based competition experiments between the non-native caprellid <i>Caprella mutica</i> and two ecologically similar native caprellids <i>Caprella linearis</i> and <i>Pseudoprotella phasma, C. mutica</i> successfully displaced both species from homogeneous artificial habitat patches after 48 hours. Patches that contained a refuge reduced the number of <i>C. linearis</i> being displaced but only when <i>C. mutica</i> was at a low density. Potentially aggressive interactions between <i>C. mutica</i> and the native <i>C. linearis</i> may have caused <i>C. linearis</i> to be displaced from the patches and could have caused significantly higher mortality of <i>C. linearis</i> compared to the controls. This is the first study to show that the non-native <i>C. mutica</i> has the ability to displace ecologically similar native species when the resource space is limited and when the density of <i>C. mutica</i> was significantly (10 times) lower than the density of <i>C. linearis</i>.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Competition between the non-native amphipod <i>Caprella mutica</i> and two native species of caprellids <i>Pseudoprotella phasma</i> and <i>Caprella linearis</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-11 01:31:40.800800","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"non-native; competition; caprellids; refuge; amphipods","OtherDescriptors":null,"Notes":null,"AnaPub":2009,"MonPub":null,"DateUpdate":"2020-09-07","DateCreate":"2009-10-22","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000270118200005","VABBcode":null,"OpenAcc":0,"DOI":"10.1017/S0025315409000435"},"refs":null,"anarec":{"AnaID":141647,"PubliDate":2009,"Pagination":"1125-1132","XtraPublOfAnaID":null,"ISBN":null,"Volume":"86","Issue":"6","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43277,"SerRR":"Journal of the Marine Biological Association of the United Kingdom.
