Meiofauna was used to evaluate this impact. One area possibly impacted by the stations’ presence (CF) and a reference area (BP) were compared. Sediment samples for meiofauna and environmental variables were obtained in two periods, at two sites and depths in each area. Densities were higher at 20-30m and nematodes were the dominant taxa (90%). Nematode densities ranged from 1,278±599 (BP1 50-60m) to 16,021±12,298 ind.10 cm<sup>-</sup>² (BP2 20-30m). A total of 68 genera were found. Sample richness ranged from 8 to 26 and diversity from 1.4 to 3.6 bits/ind, both being higher at BP 50-60m, where dominance of epistrate feeders was lower. Selective and non-selective deposit feeders were codominant with similar proportions. Maturity index was high and constant between samples. <i>Aponema, Sabatieria, Daptonema, Dichromadora</i> and <i>Halalaimus</i> were dominant, with higher densities at 20-30m. In contrast<i>, Actinonema, Molgolaimus, Oxystomina </i>and <i>Marylynnia </i>were more abundant at 50-60m. Differences in meiofauna community were found mainly between depths, but not between sites or periods, suggesting no anthropogenic impact. Nevertheless, lower Nematoda diversities and maturity index at 50-60m in CF when compared to BP may indicate a possible anthropogenic effect near EACF.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Monitoring the anthropogenic impacts in Admiralty Bay using meiofauna community as indicators (King George Island, Antarctica)","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-07 01:31:49.478902","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"Martel Inlet; Antarctic; sewage; pollution effects; meiobenthos; Nematoda","OtherDescriptors":null,"Notes":null,"AnaPub":2022,"MonPub":null,"DateUpdate":"2022-04-08","DateCreate":"2022-04-06","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000759528000001","VABBcode":null,"OpenAcc":1,"DOI":"10.1590/0001-3765202220210616"},"refs":null,"anarec":{"AnaID":350935,"PubliDate":2022,"Pagination":"e20210616","XtraPublOfAnaID":null,"ISBN":null,"Volume":"94","Issue":"suppl 1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":238892,"SerRR":"Anais da Academia Brasileira de Ciencias.
