description [EN] Seamounts are isolated topographic elevations rising steeply from the ocean floor that are characterized by high spatial heterogeneity and topographic complexity. They offer a large number of microhabitats that favour faunal diversity as well as fish feeding and spawning grounds. Though there is increasing research interest in seamounts, it is most often focused on studying large suspension feeders or fish populations, while the infauna is usually neglected. In this paper, we studied the infaunal macrobenthic diversity and distribution of sedimentary habitats on the Galicia Bank (northwest Iberian peninsula), as well as their links with the environment. We sampled 28 sites (683–2274 m depth) and identified more than 1300 specimens from 182 taxa, mostly polychaetes (67% of the total). Sediments were mainly sandy (medium, fine and very fine sands) with low levels of organic matter. We found three major macrobenthic assemblages through multivariate analyses: A, with medium depths and the lowest abundances; B, the shallowest, with medium sands and intermediate abundances; and C, the deepest and most diverse with the finest sediments. Depth, mud content and median grain size were best related to macrofauna distribution patterns, separating shallow environments with medium sands from deeper ones with finer sediments.

Ofrecen un gran número de microhá-bitats que favorecen la diversidad faunística, así como las zonas de alimentación y desove de los peces. A pesar del creciente interés de la investigación sobre las montañas submarinas, la mayoría de las veces se centra en el estudio de grandes suspen-sívoros o en las poblaciones de peces, y no tiene en cuenta la infauna. En este trabajo se estudia la diversidad macrobentónica de la infauna y la distribución de los hábitats sedimentarios del Banco de Galicia (Noroeste Ibérico), así como su relación con el ambiente. Se muestrearon 28 estaciones (683-2274 m de profundidad) y se identificaron más de 1300 especímenes pertenecientes a 182 taxones, en su mayoría poliquetos (67 % del total). Los sedimentos fueron principalmente arenosos (are-nas medias, finas y muy finas), con bajos niveles de materia orgánica. A través de análisis multivariantes se encontraron tres grandes agrupaciones macrobentónicas: A, de profundidades medias y las abundancias más bajas; B, con las profundidades más someras, arenas medias y abundancias intermedias; y C, la más diversa, la más profunda y con los sedimentos más finos. La profundidad, el contenido en fango y el tamaño medio de grano fueron las variables que mejor se relacionaron con los patrones de distribución de la macrofauna, separando los ambientes poco profundos con arenas medias de los más profundos con sedimentos más finos.This work was funded by the EC contract INDE-MARES-LIFE (07/NAT /E/000732).Peer reviewedEditorial CSICEuropean CommissionLourido, Antía [0000-0002-9787-5289]Parra, Santiago [0000-0002-9262-4229]Serrano, Alberto [0000-0001-9808-3964]Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]202520252024info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://hdl.handle.net/10261/396073https://api.elsevier.com/content/abstract/scopus_id/85219630717reponame:DIGITAL.CSIC.
