During the first 4 h after placing animals in respirometers oxygen consumption in <i>W. obesa</i> was reduced by factors between 1.2 and 3.6 times by the presence of a nylon mesh net substratum. Oxygen consumption over the first 12 h after being placed in respirometers was reduced by factors of between 1.1 and 3.9 times for <i>B. gigantea</i> by the presence of pieces of corrugated plastic pipe. The effects on oxygen consumption of acclimating animals to respirometers were only assessed for <i>W. obesa</i>. Rates during the first 12 h after placing animals in chambers were 3.6 times higher than rates between 12 and 30 h after the start of trials. Standard metabolic rates were measured in <i>W. obesa</i> in the presence of a mesh substratum and following a 12 h acclimation period after 60 days of starvation. Under these conditions oxygen consumption was 2.5 μl O<sub>2</sub> h<sup>−1</sup> for a specimen of 0.113 g dry mass. This was 3–5 times lower than routine metabolic rates previously reported for <i>W. obesa</i> and 2.4–18 times lower than routine rates for other Antarctic gammaridean amphipods.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"The influence of acclimation and substratum on the metabolism of the Antarctic amphipods <i>Waldeckia obesa</i> (Chevreux 1905) and <i>Bovallia gigantea</i> (Pfeffer 1888)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-05 01:31:06.767844","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1995,"MonPub":null,"DateUpdate":"2023-01-20","DateCreate":"2016-10-03","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:A1995QJ51000009","VABBcode":null,"OpenAcc":1,"DOI":"10.1007/BF00239063"},"refs":null,"anarec":{"AnaID":261956,"PubliDate":1995,"Pagination":"225-232","XtraPublOfAnaID":null,"ISBN":null,"Volume":"15","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":43637,"SerRR":"Polar Biology.
