The species is a strong hyper-regulator in freshwater or low salinities, while at high salinities it is a hypo-regulator. The iso-osmotic and iso-ionic points are around 27 salinity, except for haemolymph Mg<sub>2</sub><sup>+</sup>, which is around 8 salinity. There is a significant rise in the osmotic concentration during the exposure to freshwater, which coincides with a rise in the Ca<sub>2</sub><sup>+</sup>, but not in the Na<sup>+</sup> concentration. The haemolymph K<sup>+</sup> and Mg<sub>2</sub><sup>+</sup> concentrations are well regulated in all experimental salinities. These results were compared with those reported early for the northern hemisphere <i>Ocypode quadrata</i> population, which seems to be more adapted to high salinity waters than is the Guaecá population.","AbstractOtherLang":null,"BibLvlCode":"AMS","StandardTitle":"Osmo-ionic regulation in the Brazilian ghost crab <i>Ocypode quadrata</i> (Fabricius, 1787) (Crustacea, Brachyura)","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":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1989,"MonPub":null,"DateUpdate":"2001-10-04","DateCreate":"2001-08-30","SecASFANote":null,"ConfID":null,"PeerRev":0,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0},"refs":null,"anarec":{"AnaID":16980,"PubliDate":1989,"Pagination":"691-694","XtraPublOfAnaID":null,"ISBN":null,"Volume":"22","Issue":null,"BRefMon":16905,"BRefMonRR":"<b>Ros, J.D.
