Community structure of benthic megafauna on a seamount with cobalt-rich ferromanganese crusts in the northwestern Pacific Ocean

Diversity, phylogeny, and bathymetric zonation of Sirsoe (Annelida: Hesionidae) from colonization experiments in the South China Sea, with the description of three new species

“…Species replacement along a depth‐related gradient have been reported at the community level in a wide variety of deep‐sea environments, including seamounts and trenches (Chivers et al, 2013 ; Kennedy et al, 2019 ; Shen et al, 2021 ; Victorero et al, 2018 ; Zhang et al, 2021 ), but has been rarely studied on closely related taxa. Combining specimen examinations and metabarcoding analyses reveals a higher Sirsoe diversity toward the deeper sites.…”

“…However, the deep-sea seamount provides an opportunity to meet these requirements. Seamounts are isolated topographic highs in the ocean, characterized by depths exceeding 100 m. 16 As a landform widely found in the ocean, it has a unique topography and ecology. 17 The sediment (or sedimentary cores) at different depths (or heights) may be influenced by distinct biogeochemical factors, especially those from greater depths, which should have a very long history.…”

“…Recently, in situ image-based surveys have gained traction for assessing environmental baselines and monitoring anthropogenic impacts in deep-sea environments (Durden et al, 2016). For instance, visual imaging identified benthic megafaunal communities comprising five phyla in 15 and 16 transects of two seamounts within the Magellan Seamount Cluster (Shen et al, 2021;Fan et al, 2022). Similarly, in the Northeast Pacific seamounts, benthic communities consisting of 12 and 11 phyla were observed during 27 and 16 submersible dives, respectively (Lundsten et al, 2009;Du Preez et al, 2016).…”
