Metagenomic characterization of archaeal and bacterial communities associated with coral, sediment, and seawater in a coral reef ecosystem of Phu Quoc island, Vietnam.

Recent advancements in metagenomics, particularly in the studies of conservative 16S rRNA sequences, have significantly accelerated our understanding of the relationship between corals and their associated microbial communities. While bacteria are known to be closely linked with corals, there is limited understanding of the connections between archaea and corals. Unlike previous 16S rRNA studies conducted in similar tropical coral reef ecosystems, we analyzed both the archaeal and bacterial communities associated with Acropora sp. and Lobophyllia sp. corals, as well as the surrounding sediment and water columns in Phu Quoc Island, Kien Giang Province, Vietnam. The data collected were sequenced using the 16S rRNA sequencing method and further analyzed using bioinformatics tools in the R programming language, employing DADA2 and phyloseq pipelines. We examined the compositions and diversity of bacteria and archaea in coral, sediment, and water column samples to establish potential connections between these two domains. The results revealed that archaea constituted a small percentage of all samples, averaging 3.18% in coral mucus and reaching an average of 7.49% in sediment samples. Among the most abundant archaeal taxa were Crenarchaeota and Nanoarchaeota, alongside bacterial taxa Gammabacteria, Cyanobacteria, and Desulfobacteria, which are associated with important metabolic processes within coral hosts. Alpha and beta diversity analyses confirmed the highest archaeal diversity in sediment samples and the distinct existence of microbial communities in each biotope. These findings complement our knowledge of archaea’s presence and potential roles in the coral-associated microbiome.

Analysis of Coral Reef Conditions in the Waters of Panjang Island, Central Bangka Regency

Coral reefs are organisms that live at the bottom of the water and take the form of sturdy limestone formations capable of withstanding the force of ocean waves. Ecologically, coral reefs serve as habitats where various animal and plant organisms seek food and shelter. This research aims to analyze the coral reef ecosystem conditions in the waters of Panjang Island and provide recommendations for sustainable management of marine biodiversity in the waters of Panjang Island, Central Bangka Regency. The Underwater Photo Transect (UPT) method involves underwater photography using a digital or regular digital camera equipped with a waterproof housing to withstand seawater exposure. The research results indicate that the percentage of live coral cover in the waters of Panjang Island ranges from 70.07% to 14.07%, categorizing it as fair to poor according to the Minister of Environment Decree No. 4 of 2001 on the Standard for Coral Reef Damage. Fourteen coral growth forms were identified in the waters of Panjang Island, belonging to 17 coral genera. Recommendations for managing marine resources on Panjang Island include sustainable tourism development. Environmentally based tourism development can serve as a solution for sustainably utilizing coral reefs and promoting improving coastal and fisheries management based on Marine Conservation Areas.

Reef Fish Community Structure in Penyusuk Waters, Bangka Regency, Indonesia (Case Study of Artificial Reef in PT. Artha Cipta Langgeng)

Reef fishes are important components of a healthy coral ecosystem. However, when coral reefs are degraded, reef fishes also lose their habitat resulting in a decline in reef fish production and sustainable livelihood for the communities depending on it. In this study, we determined the status of reef fish communities in an artificial reef at PT Artha Cipta Langgeng in the Penyusuk waters of Bangka Regency, Indonesia. Data on reef fish communities were collected using the underwater visual census (UVC) method, including in situ and ex-situ environmental parameters. A total of 2,987 individuals belonging to 12 reef fish species and five families were recorded across three stations. The abundance of reef fish ranges from 45 to 60 ind/m², categorized as highly abundant. Diversity, evenness, and dominance indices were calculated at 1.18-1.49, 0.56-0.65, and 0.26 -0.36, respectively which are categorized as low to moderate. The environmental parameters in the artificial reef are still within the standard limit for a reef ecosystem. The study emphasizes the importance of artificial reefs as an alternative to a degraded coral reef ecosystem in supporting the thriving existence of reef fishes in the Penyusuk waters.

Manfaat Ekonomi Kelangsungan Ekosistem Terumbu Karang di Perairan Pulau Enggano Provisi Bengkulu: Sebuah Telaah Pustaka

Enggano Island has several potential biological resources that can improve the economy in the area, one of which is coral reefs. The biological resource potential of coral reef ecosystems in the Enggano Island area is one of the mainstays of community livelihoods, namely as a fishing ground for fishermen. This activity has been carried out for a long time and the intensity is getting higher from time to time, so it is necessary to conduct a study to calculate the value of the economic benefits of coral reef ecosystems in the Enggano Island area in the form of direct and indirect economic value for the benefit of sustainable management and utilisation. This literature review aims to provide information to various parties related to the Economic Benefits of Coral Reef Ecosystem Sustainability in Enggano Island Waters, Bengkulu Province. The results of the review of previous studies showed that the value of direct economic benefits amounted to Rp. 561,327,640, indirect benefits amounted to Rp. 46,342,500,000, optional benefits amounted to Rp. 2,516,077,983, and the benefits of the existence of the Enggano Island coral reef ecosystem amounted to Rp. 127,425,000,000. All of these economic benefits have been felt by fishing communities and other user communities.

Insight on thermal stress response of demosponge Chondrosia reniformis (Nardo, 1847)

Global warming has led to an increase in extreme weather and climate phenomena, including floods and heatwaves. Marine heatwaves have frightening consequences for coastal benthic communities around the world. Each species exhibits a natural range of thermal tolerance and responds to temperature variations through behavioral, physiological, biochemical, and molecular adjustments. Physiological stress leading to disease and mass mortality appears when tolerance thresholds are exceeded. Sessile species are therefore particularly affected by these phenomena. Among these sessile species, marine sponges are important members of coral reef ecosystems. To better understand the sponge thermal stress response, we tested the response of demosponge Chondrosia reniformis (Nardo, 1847) to three different temperatures (8 °C, 24 °C and 30 °C) during two exposure periods of time (4 and 14 h). Histological studies of whole parts of the sponge, biochemical analyses (Defense enzymes) and gene expression levels of some target genes were undertaken in this study. The exposure to cold temperature (8 °C) resulted in inhibition of antioxidant enzymes and less modification in the gene expression level of the heat shock proteins (HSPs). These latter were strongly upregulated after exposure to a temperature of 24 °C for 4 h. However, exposure to 30 °C at both periods of time resulted in indication of HSP, antioxidant enzymes, the gene involved in the apoptosis process (Bcl-2: B-cell lymphoma 2), the gene involved in inflammation (TNF: Tumor Necrosis Factor), as well as the aquaporin gene, involved in H2O2 permeation. Moreover, the normal organization of the whole organism was disrupted by the extension and fusion of choanocyte chambers and alteration of the pinacoderm. Interestingly, exposure to sublethal temperatures may show that this sponge has an adaptation threshold temperature. These insights into the adaptation mechanisms of sponges contribute to better management and conservation of sponges and to the prediction of ecosystem trajectories with future climate change.

Widespread Occurrence of Coral Growth Anomalies in the Republic of Maldives

In the last decades, there has been a concerning increase in the frequency and severity of coral disease outbreaks on a global scale, resulting in significant damage to the coral reef ecosystem and biodiversity. Growth anomalies (GAs) have been increasingly observed, with significantly higher occurrences in larger and older coral colonies compared to their smaller counterparts. However, there is a notable lack of knowledge and reports regarding growth anomalies in the Maldivian region. Here, we provide the first evidence of four distinct growth anomalies on three coral species, respectively on Acropora sp., Montipora sp., and Pachyseris speciosa, observed across four different locations across three atolls within the Maldivian Archipelago.

Application of Contingent Valuation Method on Economic Valuation of Coral Reef Ecosystems in Gili Gede Marine Area, West Nusa Tenggara

The most obvious way to measure non-market value is to question individuals directly about their willingness to pay for a good or service. This study evaluates the economic value of coral reef ecosystems using the contingent valuation method (CVM) technique by measuring the willingness to pay the community. Furthermore, this study aims to analyze the factors that influence the willingness to pay (WTP) and the amount of the value of the community's willingness to pay (WTP) for the conservation of coral reef ecosystems in Gili Gede waters. Sample determination in this study used purposive sampling techniques with interview structured data collection techniques guided by questionnaires. Data analysis used logistic regression for factors affecting WTP and multiple linear regression for factors affecting WTP values. The results of this study found that the average WTP value of the community was Rp. 7,257 / person in the mandatory scenario and Rp. 4,685 / person in the voluntary scenario. Factors that affect the willingness to pay the community for coral reef conservation fees in the Gili Gede fishing area are education and concern for the environment. For factors that affect the amount of the value of willingness to pay the community for coral reef conservation fees in the Gili Gede fishing area in the mandatory scenario are education, domicile and concern for the environment and in the voluntary scenario are gender, education, domicile and concern for the environment

Effects of Different Intensities and Wavelengths of Light on the Growth of Juvenile Tridacna noae

ABSTRACT Giant clams play a vital role in the preservation of coral reef ecosystems; however, the population of juvenile Tridacna sp. has experienced a decline primarily attributed to low survival rates, overfishing, marine pollution and the effects of climate change. Light intensity reportedly influences the growth and survival of giant clams. They possess the ability to thrive in oligotrophic tropical marine environments by utilising photosynthates from symbiotic zooxanthellae (Symbiodiniaeae). This study assessed the impact of different light intensities and wavelengths on growth rate (GR) and survival rate (SR) of juvenile T. noae. GRs of juvenile T. noae cultivated under 12,500 (518 ± 69%) and 20,000 lx (541 ± 40%) were significantly higher compared to those grown in 5,000 lx (271 ± 17%) (P < 0.05). Additionally, juvenile T. noae cultivated under white (662 ± 142%) or red light (554 ± 135%) exhibited lower growth rate than blue light (BL, 727 ± 146%). However, no significant change in SR was observed among experimental groups (P > 0.05). This study emphasised the significance of light intensity and wavelength in captive rearing of giant clams, contributing to the sustainable production of cultured organisms for research and conservation purposes.

Environmental generalism, holobiont interactions, and Pocilloporid corals in the warming oceans of the eastern coast of Australia

Ocean warming has been driving mortality events across the world’s coral reef ecosystems and is resulting in multifaceted ecosystem restructuring. With the rapid shifts occurring across ecosystems, questions arise of which species, in which locations, have the capacity to persevere under climate change. Environmental generalism refers to species with the biological traits that support environmental flexibility, enabling the organism to occupy a broad range of environmental conditions. Some Scleractinia have been categorised as environmental generalists and proposed as likely winners under changing climate conditions, as environmental generalists have been considered less susceptible to environmental disturbance than specialist species. Given the complexity of the holobiont structure of corals, which includes photoendosymbiosis and diverse microbial consortia, understanding the complexity of the coral holobiont–environment interaction for the generalist corals will be an important factor in accurately predicting the success of these species into the future. Here we conduct a literature search to compile topics and concepts of environmental generalism for Australia’s warming coral reef ecosystems and the breadth of holobiont responses to ecosystem restructuring. We synthesise these findings in the context of the latitudinal expanse of Australia’s coral reefs to highlight how it is necessary to understand the biological underpinnings of generalist corals.

Spatial and temporal diversity of fish captured by light traps in various habitats in coastal waters in the oldest marine protected area in Vietnam and its implications for conservation

Abstract Vietnam's oldest marine protected area, the Con Dao Archipelago, hosts a high diversity of fishes, but they are not taken into account in its management. Knowledge of the spatial and temporal diversity of fishes is critical to identify the ecological functions of protected habitats, including as nurseries and feeding grounds. One way to assess diversity is using light traps that target young fish stages. Fish were collected monthly from June 2016 to May 2017 using light traps in three main habitats: seagrass beds, coral reefs and the harbour. Morphometry and DNA barcoding were used to identify the species caught. A total of 11,293 fish were collected, of which 1,248 were barcoded and assigned to 158 species belonging to 81 genera and 34 families, evidence that coral reefs and seagrass beds in Con Dao marine protected area (MPA) are home to a highly diverse and abundant community of fish species. Species richness and Shannon diversity indices did not differ significantly among sampling sites, but both species composition and diversity indices differed in the wet and dry seasons. The abundance of fish was related to sea water temperatures, which varied significantly depending on the month. During the dry season, fish diversity peaked in April, when the water temperature was highest. Conserving fish in Con Dao MPA is important not only for the characterization of the trophic network in coral reefs and seagrass beds but also for preservation of coral reef ecosystems and endangered species. Ensuring connectivity between coral reefs and seagrass beds in Con Dao MPA would facilitate fish conservation but, at present, the MPA only focuses on protecting fragmented habitats that are home to a number of endangered mammal species. Local authorities should establish a continuum of protected areas along coastal habitats and seasonal controls on fishing as part of sustainable management of MPAs.

BIOLOGICAL IMPACTS OF ANCHORING ON SPECIES DIVERSITY, ABUNDANCE, AND DISEASE PREVALENCE OF CORAL REEFS IN KARIMUNJAWA, INDONESIA

Karimunjawa National Park (KNP) has increasing tourist visits and shipping traffic as its main tourist destination. These conditions have the potential to the degradation of coral reef ecosystems. Hence, the objective of this study was to investigate the biological effects of anchorage on disease prevalence, % coral cover, abundance, and diversity of corals. The six islands with high, medium, and low anchoring intensities were selected. The survey method was carried out by scuba diving on each selected island at depths of 3 and 8m by establishing a 2x25m line and belt transects with three replications. The statistical results indicated that there were significant differences among anchoring levels in disease prevalence. Even the coral abundance and diversity tend to be lower on the island with high anchoring activity. However, there were no significant differences in species richness, diversity index, or relative abundance among anchoring levels. Moreover, the different levels of anchoring also made no difference in the percentage of coral cover (p 0.087 &gt;0.05). This study revealed that anchoring damage might be indirectly responsible for the dispersal and elevated levels of disease. Further study is needed to identify anchoring activity and coral disease in wider areas to conserve the coral reefs of KNP.

Mangrove Plant Community Structure of Kwala Indah Village, Batu Bara Regency

Coastal areas are transitional areas between land and marine ecosystems that have high biological productivity. Mangroves are a type of plant that grows in coastal areas or river estuaries and has an ecological function by acting as the last defense against sea waves after coral reef and seagrass ecosystems, as sediment traps, as a place to find fish food, as a fish spawning ground, as a shelter, and as a place for fish farming. Mangrove Plant Community Structure Research in the Kwala Indah Village Area was conducted in August–October 2023 with the aim of knowing the types of mangroves, mangrove diversity and uniformity, dominance, Important Value Index (INP), and mangrove crown cover in Kwala Indah Village. The method used in the observation of mangrove plant community structure is to use the quadrant transect method by analyzing species density, relative density, species frequency, relative frequency, species dominance, relative dominance, and important value index at the tree, sapling, and seedling levels, as well as crown cover. Based on the results of the study, 7 species were found, namely Xylocarpus granatum, Xylocarpus mekongensis, Rhizophora apiculata, Rhizophora mucronata, Soneratia alba, Bruguiera parviflora, and Excoecaria agallocha. Xylocarpus and Rhizopora have the highest INP, diversity, uniformity, and dominance. Canopy cover is in the medium category; coastal areas are transitional areas between terrestrial and marine ecosystems that have high biodiversity values.

Condition of Coral Reef in Kelagian Besar Island

The coral reef ecosystem plays many important roles for society. One of the its role is as a tourist attraction. Kelagian Island lies near Pahawang island which is the major attraction of marine tourism in Lampung. This position makes Kelagian Island the most potential alternative island after Pahawang Island. However, sufficient information about the coral condition and profile in Kelagian Island has yet to support this potential. For that reason, a study about coral reef conditions on Kelagian island must be conducted to provide information and support the possibility of tourism development on Kelagian island. This study was conducted in August 2022 using Point Intercept Transect (PIT) in three different sites on Kelagian Island. Coral reef condition in 3 meter depth were generally in good condition, meanwhile in 7 meters depth coral reef condition were in medium state. There were 22 genera found in Kelagian island. Acropora and Porites were found dominating three meter depth. On the other hand in seven meter of depth, Goniopora and Favia were abundantly found. Diversity index, Evenness, and Dominance Index in Kelagian Island are 2,29-2,49 (medium), 1-0,83 (stable), and 0,12-0,15 (low) respectively.

Insights from the 2-year-long human confinement experiment in Grand Cayman reveal the resilience of coral reef fish communities

In March 2020, the world went into lockdown to curb the spread of the novel coronavirus (SARS-CoV-2), with immediate impacts on wildlife across ecosystems. The strict 2-year long lockdown in Grand Cayman provided an unprecedented opportunity to assess how the ‘human confinement experiment’ influenced the community composition of reef fish. Using a suite of multivariate statistics, our findings revealed a stark increase in reef fish biomass during the 2 years of lockdown, especially among herbivores, including parrotfish, with drastic increases in juvenile parrotfishes identified. Additionally, when comparing baseline data of the community from 2018 to the 2 years during lockdown, over a three-fold significant increase in mean reef fish biomass was observed, with a clear shift in community composition. Our findings provide unique insights into the resilience of reef fish communities when local anthropogenic stressors are removed for an unprecedented length of time. Given the functional role of herbivores including parrotfish, our results suggest that reductions in human water-based activities have positive implications for coral reef ecosystems and should be considered in future management strategies.

The Conditions of Coral Reef Ecosystem on Seureudong Island, South Aceh

The coral reef ecosystem on Seureudong Island, Sawang Bau Village, Sawang District, South Aceh is very important for the surrounding ecosystem, with the fringing reef type, namely the shape of its growth around the island. This study aims to determine the current condition of coral cover and the types available on Seureudong Island. The method used is the Point Intercept Transect (PIT). The results showed that the forms of coral found at the study site were branching, digitate, encrusting, foliose, massive, mushroom, plates, and submassive. The percentage of the bottom substrate is dominated by hard coral (hard coral) at 45.3%, Dead Coral with Algae/DCA (37.11%), and (9.89%), rubble of 3.56%, rock (1.56%), algae turf (1.44%), macroalgae (1%) and dead coral (0.11%). At the study site, 25 genera were found with Porites (36%) as the most common genus found. At the research location, there are also genera with a total presence of less than 1%. These genera are Acanthastrea, Ctenactis, Favia, Favites, Fungia, Gardineroseris, Goniopora, Halimeda, Heliopora, Hydnophora, Leptastrea, Montastrea, Pavona, and Seriatopora. The quality of the waters at the research location still complies with the standards of coral life. The results of these observations must be carried out periodically so that they can always update the condition of the coral reefs on Seureudong Island

Awareness and perceptions of coral reef ecosystem use and management in ‘pseudo community’ and government-managed marine protected areas in Kwale county, Kenya

Both local ‘pseudo community’ and government-managed Marine Protected Areas (MPAs) are fundamental tools in the protection of coral reef ecosystems from human-driven threats globally. Inclusive decision-making between the local community and the government in co-management is vital to the success of MPAs. Consequently, understanding community awareness and perception of the coral reef ecosystem is an essential aspect for transformative change in the sustainable use of coral reef ecosystem services. This study aimed to assess and compare the community's awareness and perceptions of coral reef ecosystem benefits in the face of different management options between Diani Chale and Kisite-Mpunguti MPAs in south coast Kenya. We collected qualitative and quantitative data through 16 focus group discussions (n = 147) and household surveys (n = 412 in Diani Chale and n = 413 in Kisite-Mpunguti MPAs) on communities living in villages within 5 kilometers of the shoreline of the selected MPAs. The findings revealed that 77.6% (640/825) of the respondents were aware of coral reef ecosystems in their area. There was a higher awareness of coral reefs among respondents in government-managed Kisite-Mpunguti MPA (84.5%, 349/413) compared to pseudo-community-managed Diani Chale MPA (70.6%, 291/412). A higher proportion of respondents in Kisite-Mpunguti relied on coral reef resources for their livelihoods (p < 0.01). Moreover, a significantly higher percentage of respondents from Kisite-Mpunguti agreed or strongly agreed that local people derive economic benefits from the establishment of MPAs compared to Diani Chale (67.6% versus 52.2%, p < 0.001). Furthermore, more respondents from Kisite-Mpunguti expressed positive support for the establishment of more government-managed MPAs (55.69% versus 32%), and Locally Managed Marine Areas (53.9% versus 38.86%). Based on these findings, inclusive support by local communities towards coral reef conservation is recommended to increase their participation in positive environmental behaviors in Kenya and other countries in the Western Indian Ocean region. Additionally, improved political goodwill is required to support the creation of more and larger areas under marine protection, especially in the Diani Chale area.

Inferring the health of coral reefs on the Egyptian coast of the Gulf of Aqaba for three branching-coral species

ABSTRACTThis investigation examined the vulnerability of three branching coral species (Acropora humilis, Pocillopora damicornis, and Stylophora pistillata) to environmental changes within the marine reserves of Taba, Nuweiba, and Dahab in the Gulf of Aqaba. Coral growth rates were assessed as a key indicator of coral reef vitality, reacting to shifting physicochemical parameters. A. humilis manifested the highest growth rate, followed by S. pistillata and P. damicornis. Site-specific data analysis found Dahab displayed the greatest coral proliferation, with Taba exhibiting the least. Accounting for seasonal changes, spring showed maximal coral growth. Statistical analysis revealed a positive correlation between salinity and coral growth rate, contrasted by a negative correlation with variables such as pH, PO4-P, and silicate (SiO4-Si). This work underscores the significant influence of environmental factors on coral growth rates, and by extension, the health of coral reef ecosystems. These findings are integral to coral reef management, suggesting mitigation of adverse environmental factors could enhance these ecosystems’ resilience against climatic shifts and human-induced stressors. By combining species, site, seasonal, and physicochemical variations, this research underlines the importance of localized conservation strategies.

Outplants of the Threatened Coral Acropora cervicornis Promote Coral Recruitment in a Shallow-Water Coral Reef, Culebra, Puerto Rico

The numerous socioeconomic and ecological challenges that coral reef degradation poses in the Greater Caribbean have led to a surge in restoration efforts. In this context, outplanting nursery-reared coral colonies has emerged as one of the most common strategies used to rejuvenate degraded reefs and reinstate critical ecosystem processes such as coral recruitment. However, the extent to which coral outplanting promotes the recruitment of coral species remains a subject of ongoing debate. This study tested the hypothesis that reintroducing the threatened coral Acropora cervicornis to a degraded coral reef promotes coral recruitment. To test our hypothesis, a series of recruitment quadrats were established in an area populated with A. cervicornis outplants and in a reference location devoid of the coral. To further investigate the relationship between A. cervicornis and coral recruitment, an experiment was implemented in which half of the quadrats in the restored area received a coral outplant, while the other half were left undisturbed. After one year, all coral recruits located within the quadrats were counted and identified. It was found that in the restored area the mean recruit density exceeded that of the reference location by a factor of 2.15. Results also unveiled a positive association between coral recruitment and the presence of A. cervicornis. Specifically, the mean recruit density in quadrats that received an A. cervicornis colony was 2.21 to 4.65-times higher than in the quadrats without coral outplants. This intriguing observation underscores the pivotal role of A. cervicornis in shaping the recruitment dynamics of corals within degraded reef areas, highlighting the potential of active coral outplanting to enhance the resilience of deteriorating coral reef ecosystems.

Abundance Megabentos in Coral Reef Ecosystems in the Waters of Gelasa Island, Central Bangka Regency.

Megabenthos is a group of fauna that inhabits the benthic zone, which is the bottom or substrate of aquatic environments (both infauna and epifauna), with a body size exceeding 10 mm (1 cm). This study aims to analyze the abundance of megabenthos in the coral reef ecosystem, examine the relationship between megabenthos abundance and the physical and chemical parameters of the aquatic environment in the coral reef ecosystem, and analyze the relationship between megabenthos abundance and coral life forms in the waters of Gelasa Island. This research was conducted in September 2022 in the waters of Gelasa Island. Megabenthos data were collected using the Bentos Belt Transect (BBT) method, while coral data were collected using the Underwater Photo Transect (UPT) method. The study identified 10 species of megabenthos in the coral reef ecosystem of Gelasa Island. The species found at the research site include Diadema setosum, Diadema antillarium, Echinothrix calamaris, Drupella cornus, Drupella rugosa, Trochus conus, Tectus pyramis, Tridacna squamosa, Tridacna crocea, and Acanthaster planci. The percentage of live coral cover at the research site ranged from 26.60% to 71.00%. Megabenthos abundance was analyzed using Principal Component Analysis (PCA) to examine the relationship between megabenthos and the physical and chemical parameters of the aquatic environment and the relationship between megabenthos and coral life forms.
