Steep environmental gradients in sea ice cover and glacier melting are observed, but much remains to be documented regarding the impact of these differences on biological communities and ecosystem processes. Here, we study how environmental variability impacts trophic interactions and ecological habitats of benthic communities along the WAP. During the Belgica 121 expedition, dominant benthic mega- and macrofauna, as well as primary producers, were sampled in multiple stations featuring different environmental conditions around the Gerlache Strait. Stable isotope ratios of carbon, nitrogen, and sulfur were measured and combined in an isotope niche analysis (SIBER). Our results suggest that changes in environmental features, notably ice-related conditions, could alter food source availability and organic matter fluxes towards benthic organisms. Isotopic compositions of abundant species were more variable in stations with stronger ice-related disturbance. Besides variability in isotopic baseline, this result could possibly also be linked to the use of a wider diversity of food sources (niche expansion) in stations affected by different ice-related conditions. Overall, our findings provide important insights towards understanding the interplay between environmental conditions and ecological habits of benthic consumers along the WAP.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Food web structure in a rapidly changing coastal environment: the West Antarctic Peninsula","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-10 01:33:03.480915","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"stable isotopes, trophic ecology, benthic communities, West Antarctic Peninsula ","OtherDescriptors":null,"Notes":null,"AnaPub":2025,"MonPub":null,"DateUpdate":"2025-11-07","DateCreate":"2025-11-05","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1,"DOI":"10.26496/bjz.2025.201"},"refs":null,"anarec":{"AnaID":435782,"PubliDate":2025,"Pagination":"93-119","XtraPublOfAnaID":null,"ISBN":null,"Volume":"155","Issue":null,"BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":44108,"SerRR":"Belgian Journal of Zoology.
