We investigated the seasonal, tidal and depth specific variation in the diet of the estuarine mysids <i>Neomysis integer</i> and <i>Rhopalophthalmus tartessicus</i> and explored its implications for the planktonic community structure of a temperate estuary (Guadalquivir Estuary, SW Spain). <i>Neomysis integer</i> is an opportunistic omnivore feeding mainly on mesozooplankton and on members of the detrital-microbial loop, shifting prey seasonally according to availability. In contrast, <i>R. tartessicus</i> showed a more carnivorous diet and shifted its target prey during seasons of low resource availability. Despite statistically significant differences in diet composition, both species shared prey of similar size, particularly juvenile <i>Mesopodopsis slabberi</i>, the most abundant mysid species in this estuary, and copepods. Although these similarities imply inter-specific resource competition, their co-existence is achieved by niche partitioning and spatial segregation: the higher osmoregulatory capacity and foraging plasticity of <i>N. integer</i> confers a broader niche breadth for this species allowing <i>N. integer</i> to inhabit the more stressful oligohaline region of the estuary where <i>R. tartessicus</i> cannot survive. We propose that this mechanism relaxes the potential for competition between <i>N. integer</i> and <i>R. tartessicus</i>.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Feeding preferences of estuarine mysids <i>Neomysis integer</i> and <i>Rhopalophthalmus tartessicus</i> in a temperate estuary (Guadalquivir Estuary, SW Spain)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"feeding; mysid; estuaries; Neomysis integer; Rhopalophthalmus tartessicus; Guadalquivir; inter-specific competition","OtherDescriptors":null,"Notes":null,"AnaPub":2008,"MonPub":null,"DateUpdate":"2018-05-17","DateCreate":"2008-04-24","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000255604100006","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.ecss.2007.09.025"},"refs":null,"anarec":{"AnaID":121907,"PubliDate":2008,"Pagination":"345-356","XtraPublOfAnaID":null,"ISBN":null,"Volume":"77","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44109,"SerRR":"Estuarine, Coastal and Shelf Science.
