Consequently, comprehensive coral reef monitoring activities have been initiated at numerous locations across Indonesia. In this study, the findings from coral reef health surveys across 14 reef sites (within 40 hectares) in the Bintan area (Riau Archipelago, Indonesia; 100 km southeast of Singapore) revealed a potentially novel epizoic yellow sponge species (<i>Phorbas</i> sp.) that overgrows coral colonies. This species, tentatively classified as a new <i>Phorbas</i> sp. (order Poecilosclerida: family Hymedesmiidae), was identified through a combined approach employing classical taxonomic methods along with DNA barcoding using the cytochrome c oxidase I (COI) gene. At every site, three permanent 20-m transects were established to annually monitor live coral coverage and species composition between 2014 and 2017. The survey indicated a notable change in the overall coral cover during this period. The abundance of coral diseases was investigated in 2014 and 2017. Additionally, the progress of <i>Phorbas</i> sp., was closely monitored (i.e., every second day for one week) at Bintan Island (site 11) during the dry season in August 2017. This approach aimed to approximate the relative impact of each incident on the coral's condition. The results indicated that the most comprehensive change occurred due to the overgrowth of <i>Phorbas</i> sp., which affected 12 scleractinian coral species across eight genera in almost all sites except one.

However, the study of their influence on the taxonomic structure and productivity of plankton is complex due to the short-term and mesoscale nature of the action of eddies. In a laboratory bioassay experiment, we simulated two mechanisms of eddy's effect on the deep phytoplankton maximum: an increase in the upward flow of deep nutrients and illumination. Doubling of nutrient additions compared to control increased chlorophyll's specific growth rate (SGR) 1.7-fold over 12 days while doubling the light intensity increased SGR by 3.5 times. During the first 4 days of the experiment, at the exponential growth stage, SGR of carbon biomass was maximum with the simultaneous doubling of nutrients and light (0.44 day⁻¹). It was statistically significantly higher than at increased nutrients but not light. These results suggest that nutrient deficiencies were less crucial for phytoplankton growth than light. The increase in the phytoplankton biomass was mainly due to the growth of a large-celled diatom <i>Pseudosolenia calcar-avis</i>. It showed the highest SGR (1.15–1.28 day⁻¹) at increased nutrients and/or light, resulting in high wet biomass of 2–3 g m⁻³ over 4 days. The ecological meaning of the obtained results is as follows. First, in the eddy, where the deep phytoplankton maximum is located close to the nutricline, its rise to more illuminated layers results in higher phytoplankton growth than the shortening distance to the nutricline. Second, increases in the upward flow of nutrients and light intensity, separate or simultaneous, stimulate the rapid reproduction of large-celled diatoms that increase the carbon-to-chlorophyll ratio by 2–4 times. Third, exposure to a typical Black Sea mesoscale cyclonic eddy can lead to phytoplankton blooms in the thermocline within a few days.</p>","PeriodicalId":49883,"journal":{"name":"Marine Ecology-An Evolutionary Perspective","volume":"45 2","pages":""},"PeriodicalIF":1.1,"publicationDate":"2024-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139762241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we examined the spatio-temporal patterns of coral recruitment and the influence of confamilial adult coral cover in the region of Toliara, southwest Madagascar. Terracotta tiles were immersed from October to late January over a 3-year period (2018–2021) at 10 stations located on major reef habitats. Overall recruitment rates were relatively high compared to those of other reefs in the Southwestern Indian Ocean, ranging from 219.20 recruits.m⁻² in 2018–2019 to 156.30 recruits.m⁻² in 2020–2021. Recruit assemblages were dominated by Acroporidae (45.5%) and Pocilloporidae (45.0%), whereas Poritidae (1.9%) and “other” recruits (3.6%) were rarely recorded. Recruitment patterns varied among stations and habitats, with higher rates in patch reef (187.06 recruits.m⁻²) and outer slope stations (156.99 recruits.m⁻²) compared to inner slope stations (108.04 recruits.m⁻²). With the exception of “other” recruits, recruitment rates decreased between 2018 and 2019 and 2019 and 2020, followed by an increase in 2020–2021 that reached or even exceeded initial values at some stations.

The dietary preferences of tropical nudibranchs were studied by the method of fatty acid trophic markers (FATM) in order to for better understanding of their trophic ecology. For this, the fatty acid profiles of two nudibranch species from the South China Sea, <i>Doriprismatica atromarginata</i> (Cuvier, 1804) and <i>Jorunna funebris</i> (Kelaart, 1859), were analyzed and trophic markers were identified. The high level of very long chain fatty acids (from C24 to C28), which are characteristic of sponges, in nudibranchs was evidence of their predation on sponges. However, the distribution of these components differed significantly between the species. The acids 24:2Δ5,9, 25:2Δ5,9, 26:2Δ9,19, and especially 26:2Δ5,9 dominated in <i>D. atromarginata</i>, but were not found in <i>J. funebris</i> that was rich in 28:2Δ5,9 and 28:3Δ5,9,19. The significant differences in the profile of these demospongic acids indicate that these nudibranchs consumed different species of sponges. The similarity between the FATMs of <i>J. funebris</i> and its potential prey, the sponge <i>Xestospongia</i>, confirmed their predator–prey relationship. <i>Doriprismatica atromarginata</i> from different sites along the Vietnam coast had different FATM profiles, which showed this nudibranch as having no any strict food specialization and feeding on various Demospongiae species. The abundance of bacterial FATMs in the nudibranchs suggests the importance of bacteria in their diet.
