At the high local temperatures ( similar to 28° C), mean egg production ranged from 3.2 to 88 eggs/female/d, and instantaneous female growth (g, as egg production) ranged from 0.04 to 0.87/d. Female growth was positively related to ambient chlorophyll concentration (r<sup>2</sup> = 0.44) and negatively to female body size (r<sup>2</sup>) = 0.29). Together these two variables explained 60% of the variation in growth. When quadratic terms for chlorophyll and a term for interaction of body size and chlorophyll were introduced, 82% of the variance in growth rate was explained. Egg production rates represent an extension of the resource and size-dependent relationship established for copepodites. In smaller species (<3.5 mu g), egg production was comparable to prior copepodite somatic growth; in larger species (>3.5 mu g), egg production is compromised at lower resource concentrations than copepodite somatic growth. Thus, it appears that egg production in tropical copepods may be frequently limited by resources in a size-dependent manner. Under conditions where growth is resource limited, we caution against the application of egg production rates for the calculation of total copepod production.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Zooplankton growth rates: the influence of female size and resources on egg production of tropical marine copepods","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-10 01:31:31.817048","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1998,"MonPub":null,"DateUpdate":"2006-06-06","DateCreate":"2006-06-06","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000075866100008","VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":99403,"PubliDate":1998,"Pagination":"79-86","XtraPublOfAnaID":null,"ISBN":null,"Volume":"132","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43352,"SerRR":"Marine Biology: International Journal on Life in Oceans and Coastal Waters.
