This study compared the macrobenthic infaunal communities in William’s Bay, Trinidad before and after a lush seagrass meadow dominated by <i>Thalassia testudinum</i> (Banks ex König) was extirpated. In 2007, <i>T. testudinum</i> aerial productivity was estimated at 2.68 ± 0.81 gm<sup>−2</sup> d<sup>−1</sup> and total biomass was 357.8 ± 224.8 gm<sup>−2</sup>, but by 2016 the bed had collapsed with zero productivity and biomass. To assess the macrobenthic infauna, five replicate cores were taken at six stations in 2007 and in 2016. Species richness, abundance and biomass all decreased from 2007 to 2016 as seagrass meadows were lost. This is likely due to fewer microhabitats and less protection from predators provided by seagrass cover. Relative abundance of the main species groups remained unchanged; polychaetes accounted for 48% of the species in 2007 and 2016, amphipods accounted for 17% in both years, decapods for 12% and 15% in 2007 and 2016 respectively, non-segmented worms for 11% (2007) and 6% (2016), molluscs for 2% (2007) and 13% (2016), echinoderms for less than 1% and a small miscellaneous group for another 1%. Deposit-feeding polychaetes were dominant across both sampling periods while carnivorous polychaetes showed a notable decline. Epifaunal amphipods dominated across both periods compared to infaunal tube-dwellers.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Seagrass loss decreases abundance, diversity and changes composition of macrobenthic infauna in a Caribbean Bay","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-27 01:32:29.387386","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2025,"MonPub":null,"DateUpdate":"2025-07-02","DateCreate":"2025-07-02","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":0,"DOI":"10.1007/s12526-025-01499-z"},"refs":null,"anarec":{"AnaID":409290,"PubliDate":2025,"Pagination":"1-17","XtraPublOfAnaID":null,"ISBN":null,"Volume":"55","Issue":"1","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":141757,"SerRR":"Marine Biodiversity.
