The older and larger copepodites of <i>Calanus</i> spp. were generally located deeper in the water column. Differences in vertical distribution between stations partly reflected a south-north gradient in developmental progress with higher abundance of older stages in the southern locations. The <i>C. finmarchicus</i> and <i>M. longa</i> observations were consistent with the hypothesis that the developmental stages distributed according to certain preferences for light intensity, and different optical properties at the four locations are likely to have affected the vertical distributions. Diel vertical migration was only observed for older developmental stages of <i>M. longa</i> while young stages of <i>M. longa</i> remained in deep waters both day and night. A mortality index indicated that non-migrating <i>Calanus</i> spp. suffered higher mortality than migrating <i>M. longa</i>.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Vertical distribution of <i>Calanus</i> spp. and <i>Metridia longa</i> at four Arctic locations","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":"Calanus; Metridia longa; mortality; optics; vertical distribution","OtherDescriptors":null,"Notes":null,"AnaPub":2008,"MonPub":null,"DateUpdate":"2018-05-17","DateCreate":"2008-08-12","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000257027500003","VABBcode":null,"OpenAcc":0,"DOI":"10.1080/17451000801907948"},"refs":null,"anarec":{"AnaID":124407,"PubliDate":2008,"Pagination":"193-207","XtraPublOfAnaID":null,"ISBN":null,"Volume":"4","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":72882,"SerRR":"Marine Biology Research.
