Müller, 1852) in the Slovenian Sea|In September 2024, a specimen of Maxmuelleria gigas (M. Müller, 1852) was found during a monitoring campaign in the Bay of Koper. This record is the second one of this less known macrobenthic species in the Slovenian Sea and one among few up to date reported in the Adriatic Sea, as well. Sediment mounds observed with an underwater video sledge on muddy bottom in the southern part of the Gulf of Trieste have been related to this species. The species distribution and density (47 per 100 m2) were estimated based on the quantification of the observed sediment mounds. The potential underestimation of the density and distribution of this species in the Gulf of Trieste in the past studies is discussed in relation to sampling methodSeptembra 2024 je bil najden osebek vrste Maxmuelleria gigas (M. Müller, 1852) med vzorčenjem v Koprskem zalivu. Poleg redkih opažanj te vrste v Jadranskem morju, ta najdba predstavlja drugega in enega od novejših zapisov pojavljanja te vrste v slovenskem morju. Sedimentni hribčki, opaženi z video sanmi na muljastem sedimentnem dnu v Tržaškem zalivu, so bili povezani z dejavnostjo te vrste. Razporeditev in gostota osebkov (47 na 100 m2 ) sta bili ocenjeni na podlagi pojavljanja sedimentnih hribčkov. Avtorici obravnavata morebitno podcenjenost gostote pojavljanja te vrste v Tržaškem zalivu, v povezavi z vzorčevalno metodoTEXTznanstveno časopisjejournalsSlovenian National E-content AggregatorNational and University Library of SloveniaZgodovinsko društvo za južno Primorsko
