Nine species in four genera are recorded (Boleophthalmus birdsongi, B. caeruleomaculatus, Periophthalmodon freycineti, Periophthalmus argentilineatus, P. darwini, P. minutus, P. novaeguineaensis, P. takita and Scartelaos histophorus). The intertidal zonation of mudskippers conforms to previously reported patterns, but subtle differences in habitat preference are observed at both intraspecific and intrageneric levels, underlining the need for in-depth investigation of habitat selection by mudskippers. Although most species inhabit littoral mudflats, some show possible habitat expansion: juvenile Periophthalmodon freycineti are found occasionally in pools on a sandy shore, and a population of Periophthalmus minutus is found to be established in a marginal mangrove habitat (a salt flat behind a pioneer mangrove assemblage). Burrow confinement during high tide is confirmed for both species of Boleophthalmus, two Periophthalmus (P. minutus and P. novaeguineaensis) and Scartelaos, but not for Periophthalmodon or the other Periophthalmus species. Territory formation is described for S. histophorus.","PeriodicalId":184392,"journal":{"name":"The Beagle : Records of the Museums and Art Galleries of the Northern Territory","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114879291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated spatial and temporal patterns in relative numbers of 11 grapsid species in northern Australian mangrove forests. The results indicated that Perisesarma spp., Neosarmatium meinerti and an undescribed species of Episesarma were most abundant, followed by Clistocoeloma merguiensis, Ilyograpsus paludicola, Sesarmoides borneensis, Metopograpsus frontalis and Sarmatium spp. Mangrove assemblage was the most important spatial factor affecting the distribution and abundance of these species. Perisesarma sp. was most abundant in mid- and low-intertidal assemblages, whereas N. m einerti and Episesarma sp. were largely limited to high intertidal assemblages. In many cases, crab species occurrence and abundance were specific to certain assemblages, areas, aspects, and times during the two-year study period, which probably reflects the specificity of species to particular environmental conditions.","PeriodicalId":184392,"journal":{"name":"The Beagle : Records of the Museums and Art Galleries of the Northern Territory","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115613381","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
