Measurements of respiration rates, lactate dehydrogenase activity (LDH) and total protein content were made daily on indivi-dual larvae (n = 181) in order to assess the level of individual variance in energy metabolism during development. On average, zoeal development in <i>H. sanguineus</i> was estimated to require 43.8 J of metabolic energy to reach a megalope stage; however, the level of individual variance in metabolic rates resulted in a range of 23.8 to 67.9 J (~3-fold difference). LDH specific activities also evidenced a wide range in individual values during development (12 to 785 µU µg -1 protein). Although respiration rates were correlated with LDH specific activity (r 2 = 0.628), it is more interesting to note the negative correlation between the variance in these measurements (r 2 = 0.796), indicating a substantial degree of individual differences in metabolic activities among these larvae. At present, phenotypic variations in physiological rate processes are not considered in life-history models of larval development, which could be an important variable determining the survival and dispersal of a larval cohort.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Larval energy metabolism and physiological variability in the Asian shore crab <i>Hemigrapsus sanguineus</i>","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-02 01:31:04.095663","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2001,"MonPub":null,"DateUpdate":"2023-02-09","DateCreate":"2003-05-12","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000171132300025","VABBcode":null,"OpenAcc":0,"DOI":"10.3354/meps218303"},"refs":null,"anarec":{"AnaID":34667,"PubliDate":2001,"Pagination":"303-309","XtraPublOfAnaID":null,"ISBN":null,"Volume":"218","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43354,"SerRR":"Marine Ecology Progress Series.
