This study represents the first attempt to use nematode descriptors in order to assign ecological quality (EcoQ) status to areas along the Sarawak coasts, thus integrating the methods actually applied by the Department of Environment (DOE). Three nematode parameters, i.e. colonizer–persister percentage, maturity index (MI), and Shannon diversity index (Hˈ), were used, as they are recognized as the best descriptors of EcoQ status in coastal habitats. The thresholds applied to the nematode parameters for the Sarawak study sites showed predominantly moderate and bad EcoQ status, with the exception of the Similajau site, which being close to a national park was found to have good EcoQ. The sites with the worst EcoQ were characterized by low salinity values, suggesting riverine inflows as a primary source of pollution, likely from the discharge of untreated wastes. This was confirmed by both the Hˈ and MI indices, which showed a close positive relation with salinity. Results obtained for the Niah site may suggest that “traces” of pollution were left in the nematode assemblages that could not be detected from other parameters of the water column. This investigation shows that analysis of nematode descriptors could be effectively applied to ecological assessment criteria within environmental policies of rapid growth countries such as Malaysia. Furthermore, it certainly suggests the need for management and conservation actions in the Sarawak coasts aimed at more sustainable use of the marine resources to prevent the loss of biodiversity.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"An approach based on nematode descriptors for the classification of ecological quality (EcoQ) of the Malaysian coasts","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-15 01:33:18.677825","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Zoobenthos; Meiofauna; Ecological quality assessment; Anthropogenic impact; Malaysia ","OtherDescriptors":null,"Notes":null,"AnaPub":2018,"MonPub":null,"DateUpdate":"2019-07-17","DateCreate":"2019-07-17","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000428260400008","VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s12526-017-0813-1"},"refs":null,"anarec":{"AnaID":312819,"PubliDate":2018,"Pagination":"117-126","XtraPublOfAnaID":null,"ISBN":null,"Volume":"48","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":141757,"SerRR":"Marine Biodiversity.
