The major faunal components are the bivalves <i>Donax variabilis</i> and <i>Donax parvula</i>, amphipods, mysids and the decapod crustacean <i>Emerita talpoida</i>. Population densities of these taxa show large seasonal fluctuations. Gut contents of benthic- feeding fishes from a 1.5-year period were used to estimate the proportion of macrobenthic populations consumed. For amphipods, estimated consumption by fishes was generally less than 1% per month. Estimated removal of <i>Donax</i> was also generally less than 1% per month, with a maximum in one month of 12 %. For mysids, estimated consumption was high, with estimated consumption exceeding total estimated population levels in seven months. <i>Emerita talpoida</i> appeared to be heavily utilized with most monthly estimates of consumption falling between 10 and 75 %. Other predators such as wading birds, ghost crabs (<i>Ocypode quadrata</i>) and planktivorous fishes, should also prey most heavily on <i>E. talpoida</i> and the mysids. It would therefore appear that populations of these taxa may be regulated by predation, while those of the amphipods and <i>Donax</i> may not be so controlled.","AbstractOtherLang":null,"BibLvlCode":"AMS","StandardTitle":"Predation and prey population variation in a high energy sand beach macrofaunal community","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":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1986,"MonPub":null,"DateUpdate":"2001-09-13","DateCreate":"2001-08-29","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":"WOS:A1986G084700022","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":16894,"PubliDate":1986,"Pagination":"305-316","XtraPublOfAnaID":null,"ISBN":"87-981066-4-3","Volume":"20","Issue":null,"BRefMon":16816,"BRefMonRR":"<b>Muus, K.
