To assess the dietary importance of motile prey, predation by <i>H. sanguineus</i> on the amphipod <i>Hyale plumulosa</i> was examined in laboratory and field experiments. Male and female crabs 7–27&nbsp;mm in carapace width were offered <i>H. plumulosa</i> in laboratory microcosms with and without sediment (sand and rocks) present. Despite sex differences in claw morphology, male and female <i>H. sanguineus</i> consumed similar numbers of amphipods. Large crabs of both sexes consumed fewer <i>H. plumulosa</i> than small crabs, and consumption was lower when sediment was present. Crab abundance was then manipulated in the field in randomized complete block experiments in the lower rocky intertidal zone. In three 14-day experiments, <i>H. sanguineus</i> had no negative effect on amphipod abundance. In fact, excluding crabs from cages led to lower amphipod densities. The results of the 2-species predator–prey laboratory experiments did not transfer to the natural environment, suggesting that complex interactions exist between <i>H. sanguineus</i> and motile amphipod prey in rocky intertidal areas.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Amphipods as potential prey of the Asian shore crab <i>Hemigrapsus sanguineus</i>: Laboratory and field experiments","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-13 01:32:08.717058","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Asian shore crab; Amphipod","OtherDescriptors":null,"Notes":null,"AnaPub":2016,"MonPub":null,"DateUpdate":"2024-07-29","DateCreate":"2024-07-29","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0,"DOI":"10.1016/j.jembe.2015.09.011"},"refs":null,"anarec":{"AnaID":393584,"PubliDate":2016,"Pagination":"18-22","XtraPublOfAnaID":null,"ISBN":null,"Volume":"474","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43229,"SerRR":"Journal of Experimental Marine Biology and Ecology.
