Field surveys reported here revealed a positive, but weak, association between this urchin and <i>H. midae</i> recruits (i.e. individuals <3 mm shell length). Selectivity indices showed that recruits occurred exclusively on encrusting coralline algae and showed preferences for strongly textured corallines, rather than those with smooth texture. On smooth corallines, around 80% of recruits were under urchins, compared with about 25% on textured corallines, suggesting that any need for shelter beneath urchins is greatest on smooth surfaces.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Relationships between recruits of abalone <i>Haliotis midae</i>, encrusting corallines and the sea urchin <i>Parechinus angulosus</i>","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":"RUBRA MOLLUSCA, GASTROPODA, GROWTH, LARVAE, ALGAE, METAMORPHOSIS, RHODOPHYTA, ABUNDANCE, MORTALITY, KELP","Notes":null,"AnaPub":2000,"MonPub":null,"DateUpdate":"2001-06-11","DateCreate":"2001-06-05","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":10635,"PubliDate":2000,"Pagination":"137-144","XtraPublOfAnaID":null,"ISBN":null,"Volume":"22","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43929,"SerRR":"South African Journal of Marine Science = Suid-Afrikaanse Tydskrif vir Seewetenskap.
