In phytoplankton, this diversity is maintained throughout periods of high population growth (that is, blooms), even though competitive exclusion among genotypes should hypothetically lead to the dominance of a few superior genotypes. Genotype-specific parasitism may be one mechanism that helps maintain such high-genotypic diversity of clonal organisms. Here, we present a comparison of population genetic similarity by estimating the beta-dispersion among genotypes of early and peak bloom populations of the diatom Asterionella formosa for three spring-blooms under high or low parasite pressure. The Asterionella population showed greater beta-dispersion at peak bloom than early bloom in the 2 years with high parasite pressure, whereas the within group dispersion did not change under low parasite pressure. Our findings support that high prevalence parasitism can promote genetic diversification of natural populations of clonal hosts.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Chytrid epidemics may increase genetic diversity of a diatom spring-bloom","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-18 01:31:35.189369","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"beta-dispersion; chytrid; diatom; genetic diversity; parasitism","OtherDescriptors":null,"Notes":null,"AnaPub":2013,"MonPub":null,"DateUpdate":"2018-02-13","DateCreate":"2013-06-03","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000324869400017","VABBcode":null,"OpenAcc":0,"DOI":"10.1038/ismej.2013.73"},"refs":null,"anarec":{"AnaID":226267,"PubliDate":2013,"Pagination":"2057-2059","XtraPublOfAnaID":null,"ISBN":null,"Volume":"7","Issue":"10","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":120798,"SerRR":"The ISME Journal: Multidisciplinary Journal of Microbial Ecology.
