Comparisons of burrowing in similar sediments showed that: (a) all species had about a two-fold increase in mean time to burial in dense tube-mats of polychaetes and crustaceans; (b) hard-bodied taxa were particularly restricted by roots of Zostera marina L. and were often incapable of penetrating them; (c) roots and tubes together had the greatest impact, with mobility 3 to 37 times slower; and (d) burrowing ability increased when sediments were “pre-burrowed” for 1 day. Comparisons of burrowing rates in different sediments showed effects of physical origin (sediment compaction or sorting). Overall these physical effects were second to those of purely biogenic origin, sediment binding and cohesion by roots and tubes. Nonetheless, physical effects exceeded those of extremely high densities of tube-builders (3160 individuals ·0.01 m−2). In all substrata the movement of larger individuals, and the larger of morphologically similar pairs of species (listed second above), were more restricted by roots and tubes than were smaller ones. The results suggest a general mechanism by which dense assemblages of tube-builders and seagrasses may restrict older and larger burrowing organisms. Because physical properties of the sediment and the abundance of other burrowers are also factors affecting mobility, it is not now possible to predict what situations will render this mechanism of interaction important to natural communities.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Mechanisms of spatial competition in marine soft-bottom communities","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-13 01:31:53.278269","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1982,"MonPub":null,"DateUpdate":"2022-03-18","DateCreate":"2022-03-18","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1982NK13000002","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/0022-0981(81)90177-5"},"refs":null,"anarec":{"AnaID":350504,"PubliDate":1982,"Pagination":"17-33","XtraPublOfAnaID":null,"ISBN":null,"Volume":"60","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43229,"SerRR":"Journal of Experimental Marine Biology and Ecology.
