“…Based on the global water temperature patterns, the distributional ranges of fish species can be categorized primarily into tropical, subtropical, temperate, and boreal distributions, progressing latitudinally from low- to high-latitude regions [ 57 ]. The marine environment of the Korean Peninsula is classified within a typical temperate climate zone, characterized mainly by temperate species; however, subtropical species are also prevalent during the summer season and in sea areas at lower latitudes, such as Jeju Island [ 58 , 59 ]. According to marine zoogeography, the study area is situated in the western Pacific boreal region [ 60 ] and is home to several boreal marine fishes, such as Pacific cod and walleye pollock [ 61 , 62 ].…”

This study assessed variations in demersal fish assemblages with respect to the study site and water depth. Seasonal samplings from May 2018 to March 2019 were conducted along the northern (Ayajin, Goseong) and southern (Hupo, Uljin) sites of the East Sea off the Korean coast, using commercial gill nets. Samples were collected at depths of ~50, ~80, ~150 m across the study sites, with concurrent monitoring of water column structures. A total of 73 species and 6250 specimens were collected. Distinctive fish species compositions were observed according to the study site and depth. Although Glyptocephalus stelleri was the most abundant fish species in both Ayajin and Hupo, Gadus macrocephalus, Icelus cataphractus, and Alcichthys elongatus were most predominant in Ayajin, whereas Cleisthenes pinetorum, Hippoglossoides dubius, and Gymnocanthus herzensteini were more prevalent in Hupo. In terms of depth layer, in Ayajin, G. stelleri dominated in both intermediate and deeper layers, with Hemilepidotus gilberti, A. elongatus, Enophrys diceraus common in shallower depths. Conversely, in Hupo, G. stelleri, C. pinetorum, and A. nadeshnyi dominated across all depth layers, whereas Dasycottus setiger and G. herzensteini dominated in deeper and shallower depths, respectively. Significant influences of the study site and water depth on fish assemblage structures were observed due to variations in water temperature at the seasonal thermocline boundary.

“…Biodiversity was assessed using Autonomous Reef Monitoring Structures (ARMS), a well‐established, standardized method for assessing benthic marine biodiversity (Leray & Knowlton, 2015) used globally in a variety of ecosystems, including coral reefs (e.g. Al‐Rshaidat et al., 2016; Carvalho et al., 2019; Chang et al., 2020; Leray & Knowlton, 2015; Pearman et al., 2016, 2018, 2020; Pennesi & Danovaro, 2017; Plaisance et al., 2011, 2021; Thomasdotter et al., 2023; Timmers et al., 2020, with uses reviewed in Yang et al., 2023). Each ARMS is a ~22 × 22 × 25 cm PVC structure of nine stacked plates with alternating open and partially closed (‘cave’) layers where small benthic motile and sessile organisms settle (Figure S1).…”

Both human populations and marine biodiversity are concentrated along coastlines, with growing conservation interest in how these ecosystems can survive intense anthropogenic impacts. Tropical urban centres provide valuable research opportunities because these megacities are often adjacent to mega‐diverse coral reef systems. The Pearl River Delta is a prime exemplar, as it encompasses one of the most densely populated and impacted regions in the world and is located just northwest of the Coral Triangle. However, the spatial and taxonomic complexity of this biodiversity, most of which is small, cryptic in habitat and poorly known, make comparative analyses challenging. We deployed standardized settlement structures at seven sites differing in the intensity of human impacts and used COI metabarcoding to characterize benthic biodiversity, with a focus on metazoans. We found a total of 7184 OTUs, with an average of 665 OTUs per sampling unit; these numbers exceed those observed in many previous studies using comparable methods, despite the location of our study in an urbanized environment. Beta diversity was also high, with 52% of the OTUs found at just one site. As expected, we found that the sites close to point sources of pollution had substantially lower diversity (44% less) relative to sites bathed in less polluted oceanic waters. However, the polluted sites contributed substantially to the total animal diversity of the region, with 25% of all OTUs occurring only within polluted sites. Further analysis of Arthropoda, Annelida and Mollusca showed that phylogenetic clustering within a site was common, suggesting that environmental filtering reduced biodiversity to a subset of lineages present within the region, a pattern that was most pronounced in polluted sites and for the Arthropoda. The water quality gradients surrounding the PRD highlight the unique role of in situ studies for understanding the impacts of complex urbanization pressures on biodiversity.

“…Artificial settlement plates offer a straightforward and effective approach for assessing the recruitment and growth of benthic communities [18]. Autonomous reef monitoring structures (ARMS) are an internationally standardized technique for monitoring hard benthic substrates in various regions to efficiently gather data on marine organisms while reducing the sampling effort, lowering costs, and minimizing habitat destruction [19]. ARMS have recently been introduced as a sampling tool to assess cryptic reef biodiversity [20,21] and provide a standardized method that has been used since 2006 to conduct visual censuses of species abundance and estimate biodiversity via molecular analyses [21].…”

Assessing the effectiveness of artificial structures as a monitoring tool for benthic diversity in temperate reefs is crucial to determining their relevance in reef conservation and management. In this study, we utilized Autonomous Reef Monitoring Structures (ARMS) to evaluate sessile benthic communities that colonized ARMS units after 12 and 34 months of immersion within distinct habitats (coral-dominated and macroalgae-dominated habitats) in Jeju Island, Korea. We used two methods: image analysis of the ARMS plates and DNA metabarcoding of the ARMS units. We found significant differences in the sessile benthic community between the plate faces, installation periods, and habitats. DNA metabarcoding also revealed differences in sessile benthic diversity among habitats. Additionally, we identified the Lithophyllum genus within the crustose coralline algae community, whose dominance might trigger a transition to coral-dominated habitats in Jeju Island. We recommend integrating ARMS image analysis with DNA metabarcoding to enhance and complement studies focusing on benthic diversity. By utilizing ARMS, this study provides valuable information for understanding sessile benthic communities and biodiversity, contributing to an enhanced understanding of the responses of ecological communities to climate change.
