Retrospective analysis of collections made during peak recruitment in austral autumn showed a significant increase in the abundance of planktonic crustaceans by two orders of magnitude (from 3.74 × 10<sup>3</sup> ind.m<sup>-2</sup> in 1951 to 7.03 × 10<sup>5</sup> ind.m<sup>-2</sup> in 1996). This long-term increase was accompanied by a shift in the community size structure, which parallelled altered regimes of anchovy and sardine, two size-selective planktivores. The increase in crustacean zooplankton could be related to the observed long-term intensification of coastal upwelling in the region and a reduction in predation by declining stocks of pelagic fish over the past four decades.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Long-term increase in crustacean zooplankton abundance in the southern Benguela upwelling region (1951-1996): bottom-up or top-down control?","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-20 01:31:26.962088","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"     Benguela Current     long-term trends     predation     upwelling     zooplankton","OtherDescriptors":null,"Notes":null,"AnaPub":1998,"MonPub":null,"DateUpdate":"2013-02-06","DateCreate":"2001-01-16","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000076754200028","VABBcode":null,"OpenAcc":1,"DOI":"10.1006/jmsc.1998.0387"},"refs":null,"anarec":{"AnaID":5634,"PubliDate":1998,"Pagination":"803-807","XtraPublOfAnaID":null,"ISBN":null,"Volume":"55","Issue":"4","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44710,"SerRR":"ICES Journal of Marine Science.
