We conducted shipboard grazing experiments and fine-scale vertical zooplankton sampling to resolve these behaviors. Day/night feeding differences were compared in the center of several warm-core Gulf Stream rings, under conditions of no lateral water mass exchange, in the mesohaline portion of Chesapeake Bay and when following drogues in the Chesapeake Bay plume. Day/night variations in copepod biomass in the surface mixed layer were greater in neritic waters as compared to the open ocean stations. Day/night differences in weight-specific copepod filtration rates varied less than biomass. At the neritic stations copepod grazing was often higher at night, whereas at the oceanic stations day/night grazing rates were similar or daytime grazing rates were highest. The night/day ratio of zooplankton grazing impact on the phytoplankton community (the product of zooplankton biomass and their weight-specific grazing rate) averaged 4.8 in the Chesapeake Bay plume and 1.6 in warm-core Gulf Stream rings. Our results suggest that at lower food levels, there often are less day/night differences in the removal rate of phytoplankton by the copepod community.","AbstractOtherLang":null,"BibLvlCode":"AMS","StandardTitle":"Day/night differences in the grazing impact of marine copepods","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":"Copepods; Diel","OtherDescriptors":null,"Notes":null,"AnaPub":1988,"MonPub":null,"DateUpdate":"2015-05-26","DateCreate":"2015-05-26","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0,"DOI":"10.1007/978-94-009-3103-9_3"},"refs":null,"anarec":{"AnaID":247234,"PubliDate":1988,"Pagination":"21-30","XtraPublOfAnaID":null,"ISBN":"978-94-010-7895-5","Volume":"47","Issue":null,"BRefMon":247226,"BRefMonRR":"<b>Boxshall, G.A.; Schminke, H.K.
