Zoospores (the asexual reproductive cells) exhibit up to a 6 fold higher sensitivity to UV-B exposure than the mature thalli (measured as chlorophyll fluorescence, F<sub>v</sub>), and differences in growth rates were also found. Consistent patterns emerged throughout these experiments in variable fluorescence, germination success and growth rates, indicating a greater sensitivity in the sexual reproductive phase of the life cycle compared with the asexual phase. Inhibition of germination success (up to 50%) and growth rates (up to 16.4%) of settled gametes and zoospores after 1-h exposures to elevated levels of UV-B (equivalent to 27 and 31% ozone depletion) showed that damage to the reproductive cells was irreversible. In conclusion, the ecological significance of elevated UV-B exposure in the marine environment may be seriously under-estimated if effects on the early lifestages of algae are not considered.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"The influence of UV-B radiation on the reproductive cells of the intertidal macroalga, <i>Enteromorpha intestinalis</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-14 01:31:05.265291","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2001,"MonPub":null,"DateUpdate":"2003-02-21","DateCreate":"2003-02-21","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000172305200001","VABBcode":null,"OpenAcc":0,"DOI":"10.1016/S0166-445X(01)00194-1"},"refs":null,"anarec":{"AnaID":32587,"PubliDate":2001,"Pagination":"1-11","XtraPublOfAnaID":null,"ISBN":null,"Volume":"56","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42203,"SerRR":"Aquatic Toxicology.
