Depth-habitat use, availability of edible algae and zooplankton densities were recorded to examine seasonal changes in intensity of competition between <i>Daphnia</i> and the other herbivores in the lake. Early in July, the exephippial generation of Daphnia aggregated near the surface, independently of body-size. In late July, when fish planktivory was expected to increase, the daphnids moved down during the day. In August, as intraspecific competition for food intensified, small and large <i>Daphnia</i> partitioned the water column, with larger individuals staying deeper. In September, <i>Daphnia</i> became dominated by large individuals, edible phytoplankton reached the seasonal minimum, and the vertical distribution of <i>Daphnia</i> gradually stretched out towards the surface. The observations on food availability and zooplankton densities suggest that interspecific competition intensified by the end of July. Species and stages that were most exposed to exploitative and interference competition by <i>Daphnia</i> were those staying deeper, because their vertical distribution overlapped more with the larger, competitively superior daphnids. These susceptible competitors included <i>Keratella cochlearis</i> and <i>Synchaeta</i>, among the rotifers, and nauplii and early copepodite stages of <i>Cyclops scutifer</i>. Depth-habitat use is discussed in relation to copepod development, zooplankton dynamics and predator-mediated coexistence.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Size-dependent habitat choice in <i>Daphnia galeata</i> Sars and size-structured interactions among zooplankton in a subarctic lake (lake Lombola, Norway)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-08 01:31:59.177304","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2003,"MonPub":null,"DateUpdate":"2014-11-21","DateCreate":"2004-03-19","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000183124600001","VABBcode":null,"OpenAcc":0,"DOI":"10.1023/A:1023942931825"},"refs":null,"anarec":{"AnaID":58580,"PubliDate":2003,"Pagination":"107-122","XtraPublOfAnaID":null,"ISBN":null,"Volume":"37","Issue":"2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42197,"SerRR":"Aquatic Ecology.
