Abstract Historical coral skeleton (CS) δ 18 O and 15 N records were produced from samples recovered sedimentary deposits, held in natural history museum collections, cored into modern heads. These used to assess the influence of global warming regional eutrophication, respectively, on decline coastal communities following development Pearl River Delta (PRD) megacity, China. We find that, until 2007, ocean was not a major threat estuary; instead, nitrogen (N) inputs dominated impacts. The...
Coral reefs play a significant role in marine ecosystems, but are increasingly facing degradation, primarily due to ocean warming. Effective monitoring and management methods crucial for the conservation rehabilitation of these accurate mapping is essential conserving coral reef ecosystems. Utilizing remote sensing data an effective approach achieve high-quality maps. However, water column interference can disturb reflected signal data. In this study, depth-invariant index (DII)...
Assessing the effectiveness of artificial structures as a monitoring tool for benthic diversity in temperate reefs is crucial to determining their relevance reef conservation and management. In this study, we utilized Autonomous Reef Monitoring Structures (ARMS) evaluate sessile communities that colonized ARMS units after 12 34 months immersion within distinct habitats (coral-dominated macroalgae-dominated habitats) Jeju Island, Korea. We used two methods: image analysis plates DNA...
This study was carried out to determine the levels of resistance and resilience kelp forests large-scale physical disturbances. Our site, Seongsan, Jeju Island, impacted by super typhoon ‘Hinnamnor’. Before typhoon, Seongsan had shown high ecosystem stability. results indicated that ecological stability a forest facing severe is strongly linked prevailing environmental conditions. Although impact resulted in significant loss brown macroalgae canopy, Ecklonia cava remained dominant within...
Alveopora japonica is restricted to the Asia-Pacific region, ranging from subtropical temperate waters. In 2016, a massive bleaching event of an A. population was observed at south coast Jeju Island, South Korea, which within its northernmost limit. After event, most colonies had recovered by 2017.
Aim of study Marine climatic transition zones are boundary areas major climate zones, here the between subtropical and temperate zones. They present containing high abundance organisms living at limit their physiological tolerance. These marginal populations particularly sensitive to changes in environment. As such, marine excellent natural playgrounds for change-related hypothesis testing, especially with respect habitat response ocean warming. The biogenic habitats around Jeju Island,...
Kelp forests in Korean waters, mainly consisting of Ecklonia cava, provide ecologically and economically important ecosystems. However, they are severely threatened by increasing sea surface temperature (SST). In 2023, an unusually high SST was observed the northern East China Sea, where average from August to November 2023 found be 1.1 °C higher than during same period over last two decades. Our photo images videos reveal feeding on E. cava populations tropical herbivore rabbitfish (Siganus...
Jeju Island, located in the northern East China Sea, is experiencing a rapid rise water temperature due to climate change. This has led increased activity of subtropical species and extreme fluctuations coastal ecosystems, such as macroalgal blooms coral bleaching. Additionally, region more frequent intense typhoons. study investigated green tides caused by Ulva, particularly Ulva ohnoi, species, effects typhoons on these through photographic analysis coastline. The area was consistently...
Environmentally adapted and resistant hard soft coral communities within the high-latitude Asia–Pacific marginal distribution zone are thriving, despite their comparably stressful environment (unfavorable winter water temperature light regimes). Korea’s Jeju Island is famous for its diverse abundant communities, which coexist with reef-building corals. Although antagonistic interactions between corals generally feature as winner, we observed a of species Dendronephthya gigantea completely...
Benthic habitat zonation is described from in situ observations and seabed photographs taken the coastal area of Weno Island, Chuuk, Micronesia. Habitat groups, types, boundaries are defined by visible substratum characteristics (i.e., digital imaging photo-quadrats along transect lines), cluster ordination analyses using relative coverage percentage identified classification categories. The statistical similarity between groups determined Analysis (ANOSIM). with significant influence on...
The genus Semicytherura Wagner, 1957 has nearly 300 species, is common in shallow and marginal marine habitats, a worldwide distribution. It divided into several species groups, of which the henryhowei Hanai & Ikeya, 1977 group one most frequently recorded temperate Asia. A previous study indicated that many its members are actually complexes, morphotypes could be distinguished by carapace shape ornamentation. We review these complexes conclude currently contains 29 nine undescribed....
The aim of this study is to suggest an optimal survey method for coastal habitat monitoring around Weno Island in Chuuk Atoll, Federated States Micronesia (FSM). This was carried out compare and analyze differences between situ (PHOTS) high spatial satellite imagery (Worldview-2) with regard the distribution patterns Island. field data showed following coverage types: sand 42.4%, seagrass 26.1%, algae 14.9%, rubble 8.9%, hard coral 3.5%, soft 2.6%, dead 1.5%, others 0.1%. 26.5%, 23.3%, +...
The coral symbiotic algae zooxanthellae is often expelled from the host as under physiological stress, causing to turn completely white. Such bleaching events are occurring more frequently with increase in global warming, ocean acidification and increased level of anthropogenic impacts such eutrophication. In present study, we investigated effects inorganic nutrients including ammonium, nitrate, phosphate elevated water temperature on density fragment branching Acropora nobilis....
The fish species composition of seagrass bed in Chuuk Lagoon, Micronesia, was investigated every month from August 2009 to July 2011, using a seine net for caught. A total 32 belonging 18 families under 6 orders were identified during the study period. Of these fish, Atherinomrus lacunosus, and Strongylura incise major dominant representing 85.0% number individuals. individuals high December 2009, 2010. biomass highest September 2010 diversity index higher April, 2011. 14 could be divided...
Abstract Fatty acids (FAs) are the main components of lipids in corals. We examined FA profiles from five symbiotic coral species belonging to different genera ( Acropora , Pavona Turbinaria Favites and Platygyra ) four families (Acroporidae, Agariciidae, Dendrophyllidae, Faviidae). separated symbionts host tissue investigate interaction between tissue. After separation, we used profiles, particular specific FAs e.g. 16:0, 18:0, 18:3n-3, 20:5n-3, 22:6n-3) their ratios (EPA:DHA, PUFA:SFA) as...
