There were differences in the fish assemblages associated with the different modules with the Fish Towers (large subsurface steel buoys) having the highest mean fish abundance and biomass. The design of the modules that are incorporated into an AR design have a considerable influence in shaping the assemblage and biomass of fishes at an AR site. Some differences between module types were not immediately obvious due to the close spacing of modules which created a relatively contiguous fish assemblage across the whole reef field.

Understanding how these corals respond to environmental fluctuations can provide insights into their resilience against thermal stress. A seven-year assessment of the dominant reef-building coral Montastraea cavernosa was conducted in the oceanic archipelago of Fernando de Noronha, Southwestern Atlantic (3.86°S 32°42W), using a colony-based approach. We quantified healthy and bleached coral areas, colony area covered by algae, colony's border interactions with benthic organisms, and adjacent benthic cover during austral spring and relate eventual patterns with environmental drivers. Between 2013 and 2019, analyses of 43 colonies across three sites (totaling 167 observations) revealed that they largely remained healthy, with over 70 % of the area exhibiting a vivid dark color, and only small bleached areas (less than 1 %), despite a moderate-strong heatwave in 2018–2019. The adjacent algal cover fluctuated and was positively related to more turbid waters (higher sedimentation and organic matter input), but the monitored colonies were more contacted than expected by chance by algal turfs, a benthic group that does not impose a major competitive threat to corals. While it is unclear if corals bleached between sampling periods, the results suggest that reefs dominated by M. cavernosa may resist/recover thermal stress events, differing from the responses observed in the Indo-Pacific and Caribbean, highlighting the importance of including these marginal reefs in global assessments of coral responses to climate change.</div></div>","PeriodicalId":18204,"journal":{"name":"Marine environmental research","volume":"208 ","pages":"Article 107104"},"PeriodicalIF":3.0,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143715928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The data set was obtained through a series of underwater surveys conducted between June and September 2024 at 140 surveyed stations, covering a total area of about 0.534 km². Spatial and species-specific surface area (m²), cover percentage (%), and depth limits (m) of seagrass meadows were estimated from underwater records collected along line transects.

This limitation attributed to reductions in light penetration caused by high primary production and excessive pollution loads in the SoM.

Modelling and predicting the distribution of potential habitats of cephalopods and their changing habitat spatial patterns under climate change scenarios can provide an essential scientific foundation for cephalopod habitat conservation and fisheries ecosystem management in the context of climate change. The trawl survey data collected along Zhejiang offshore in the spring and autumn of 2017–2023, in conjunction with marine environmental data including sea surface temperature (SST), sea surface salinity (SSS), dissolved oxygen concentration (DO) and chlorophyll-a concentration (CHLA), collected by temperature-salt-depth instrument, were employed to simulate and predict the potential habitat distribution of <em>Uroteuthis duvauceli</em>, <em>Abralia multihamata</em>, and <em>Sepiella maindroni</em> in the four RCP climate scenarios in 2100 by random forest as a species distribution model. The results demonstrated that the Random Forest predictions were accurate and reliable, with an AUC exceeding 0.8 for each group and a standard deviation below 0.05. The main environmental factors affecting the habitat distribution of three cephalopod species are SST and SSS, with an average contribution rate of 0.28 in spring and 0.33 in autumn. The average contribution rate of SSS in spring is 0.32, and in autumn it is 0.29. The response curves demonstrated that the three cephalopod species exhibited varying degrees of response to changes in SST and SSS. During the spring period, the optimal habitat for cephalopods was characterised by SST ranging from 18 °C to 20 °C, and SSS exceeding 28 ‰. In contrast, in autumn, <em>S</em>. <em>maindroni</em> exhibited a preference for warmer water compared to <em>U</em>. <em>duvauceli</em> and <em>A. multihamata</em>. The potential habitat suitability zones of cephalopods under high gas emission scenarios were found to mainly extend to the southern and northern coast of Zhejiang. Among them, the area of the high adapted zone of <em>S</em>. <em>maindroni</em> increased by 352 % in the RCP4.5 scenario, the area of the high adapted zone of <em>U</em>. <em>duvauceli</em> increased by 69 % in the RCP4.5 scenario, and the area of the high adapted zone of <em>A. multihamata</em> increased by 69 % in the RCP8.5 scenario.
