Some quantitatively important diatoms, such as species of <i>Chaetoceros</i> and <i>Skeletonema</i>, have special strategies with respect to the timing of the planktonic phase that cannot be explained purely on the basis of environmental clues. In Norwegian waters and elsewhere, the first <i>Chaetoceros</i> bloom of the growth season usually starts in mid March, initiated by <i>C. socialis</i>. Other <i>Chaetoceros</i> species appear in the water column later. Species of dinoflagellates like <i>Alexandrium</i> also bloom at certain times of the year. In many cases, phytoplankton inocula originate from resuspension of bottom-dwelling spores or cysts rather than from residual planktonic vegetative cells, and it is probable that, in some species, inoculation events are controlled by endogenous biological clocks. The sequential appearance of different <i>Chaetoceros</i> species may be related to day-length-regulated germination of sports. Most <i>Chaetoceros</i> species have few generations, but they appear at opportunistic times in the plankton. In contrast, <i>Skelelonema costatum</i> and <i>Scrippsiella trochoidea</i> appear at any time of the year. Some modelling results can be improved by including the dynamics of phytoplankton seed stocks in the sediments.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Phytoplankton models and life history strategies","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2025-07-02 08:33:14.980000","timezone_type":1,"timezone":"+00:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Population-dynamics; Interannual variability; Spring bloom; Environmental-factors; Northeast japan; Ocean; Western norway; Nova-scotia","OtherDescriptors":"POPULATION-DYNAMICS, BARENTS SEA, INTERANNUAL VARIABILITY, ENVIRONMENTAL-FACTORS, NORTHEAST JAPAN, WESTERN NORWAY, SPRING BLOOM, NOVA-SCOTIA, ONAGAWA BAY, OCEAN","Notes":null,"AnaPub":2000,"MonPub":null,"DateUpdate":"2001-06-11","DateCreate":"2001-06-05","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000168463600024","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":10648,"PubliDate":2000,"Pagination":"323-338","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.
