Abstract

Gaining extensive knowledge of prey sources is an essential approach for understanding trophic structure and relationships, especially in highly diverse coral reef ecosystems. Groupers are a major Asian reef fish commodity, making it important to study grouper prey and the trophic relations involved. The wide distribution of groupers across different environments could lead to distinctive predatory behaviour. Therefore, this study was conducted to investigate and compare the taxonomic classification and composition of prey in the diets of two common groupers (Epinephelus areolatus and E. malabaricus) based on DNA metabarcoding of stomach contents and potential prey detection using environmental DNA tools at sites in the coral reefs of Raja Ampat, Indonesia. DNA recovered from the water column comprised taxa from the Arthropoda, Chordata, Cnidaria and Mollusca, several of which were also found in grouper guts, with Cnidaria the most abundant class. Diversity was high for potential prey species in the environment and prey consumed by each grouper species. The high overlap in prey identified from gut contents indicates these two epinephelids have a similar feeding strategy. However, nMDS ordination showed segregation between the prey consumed by each species and potential prey available in the environment. The results indicate a low likelihood of competition between the two grouper species, related to the abundance and wide choice of potential prey in the highly biodiverse Raja Ampat coral reef ecosystem.

Abstract

Halophila major is a new species with a wide distribution across various regions in Indonesia. The species was identified in 2020 through a combination of morphology and molecular approaches. Several studies have shown that it has a similar morphology to H. ovalis, which causes significant confusion during identification. Therefore, this study aims to describe the key identification and habitat of H. major and summarize seagrasses study opportunities based on the trend of published articles. A bibliometric analysis was used to summarize the habitat, morphometrics, molecular confirmation, and trend of seagrass topics in Indonesia. Based on the scientific articles, H. major has bigger morphometrics than H. ovalis. In addition, the number of paired and branching cross veins was reported to be an identification key of H. major. The species was also considered a deep ovalis found in 2-4 m depth. Genetically, the Internal Transcribed Spacer (ITS) gene marker was appropriate to showits phylogenetic tree. H. major was also classified into different clades with H. ovalis due to various factors. The results showed that genetics, tourism, and restoration were topics with the potential to be explored in the future. This study recommended collaborating in multi-institution to transfer knowledge, technologies, and project arrangements for seagrass exploration.Keywords:BibliometricHalophilaMarine angiospermaeMarin plantRediscoverySpecies

Abstract. Widiarti R, Zamani NP, Bengen DG, Madduppa H. 2021. Morphotype diversity of Prorocentrum lima in the western part of Indonesian waters. Biodiversitas 22: 609-616. Prorocentrum lima is one of the toxic benthic dinoflagellates, known to produce various toxins, including okadaic acid and dinophysis toxins. The species have a wide range of morphological variability, and possess morphotype diversity, which makes it essential to have detailed morphology observation for identification and other purposes. However, such comprehensive observation has never been reported from Indonesian waters. This study aims to determine the morphological characteristics (including pore size and number of pores) of P. lima morphotypes, in the western part of Indonesian waters (Bintan Island, Belitung Island, Seribu Islands, and Karimunjawa Islands). The results showed three different and unique morphotypes of P. lima, namely morphotype 1, morphotype 2, and morphotype 3. Three clusters were presented by Cluster Analysis, corresponded to the three morphotypes, which were Belitung Island clusters, Seribu Islands and Karimunjawa Islands cluster, and Bintan Island cluster, respectively. These findings support distribution of P. lima and its potential risk of toxicity in Indonesian waters, which prompts the necessity of conducting future research, to avoid the negative impact.

Abstract. Widiarti R, Zamani NP, Bengen DG, Madduppa H. 2022. Molecular characterization of toxic benthic dinoflagellate, Prorocentrum lima in west Indonesian waters using LSU 28S rDNA gene. Biodiversitas 23: 3257-3263. Prorocentrum lima is one of the toxic benthic dinoflagellates known to cause Diarrhetic Shellfish Poisoning (DSP), which is also associated with ciguatoxin-producing species, Gambierdiscus toxicus that causes Ciguatera Fish Poisoning (CFP). P. lima has a wide range of morphological variability and genetic diversity, but such research has never been reported from Indonesian waters yet. This study aimed to determine the molecular characteristics of P. limain west Indonesian waters, namely Bintan Island, Belitung Island, Seribu Islands, and Karimunjawa Islands. Molecular characterization was conducted by amplification on large subunit (LSU)28S rDNA gene. Extraction was conducted using freeze-thaw which was continued with single cell PCR method. Genetic distance values and phylogenetic analysis were analyzed using MEGA software. Based on molecular analysis, P. lima from this research was divided into two subclades, namely subclade A from Seribu Islands and Belitung Island, and subclade B from Karimunjawa Islands and Bintan Island. P. lima from Bintan Island showed a closer relationship with the reference sequence from the Genbank. Observation of molecular characters of P. lima showed that the genetic diversity of P. lima depended on the variation of the island’s morphogenesis type.These findings could support a further study on the distribution of P. lima in Indonesian waters, related to the genetic variation and toxin production, since Indonesia consists of many small islands.

Abstract

Graphical Abstract   Highlight Research The large river discharge from several tributaries causes strong stratification in the Banyuasin Estuary. RoFI in the Banyuasin Estuary does not only occur seasonally, but can also occur in daily cycles. Tidal dynamics control RoFI dynamics in the Banyuasin Estuary. Estuarine plumes formed on the surface based on synoptic imagery prove that RoFI can also extend seasonally.   Abstract The Region of Freshwater Influence (RoFI) is the river-sea transition zone where freshwater, suspended materials, and associated properties are exchanged and redistributed by estuarine dynamics. This study is the first to identify RoFI and contributes to increasing primary productivity in aquatic environments. This research aims to identify physical processes such as tides and currents in the RoFI based on observational CTD data. CTD measurements (14 stations) collected data salinity, temperature, density, and turbidity, visualized using ODV. Tidal and current data identified RoFI dynamic controls. Sentinel-2A imagery mapped the surface plume. RoFI dynamics exhibit significant seasonal and daily changes. Low salinity 10–15 PSU, indicating freshwater intrusion, dominates, with residual currents typically ranging from 0.1 m/s to 0.2 m/s. PCA analysis 91.32% variability demonstrates that the RoFI expands during ebb tide and narrows during flood tide due to estuarine intrusion of high-salinity oceanic currents. RoFI in the Banyuasin estuary introduce freshwater, nutrients, suspended particulates, and even pollutants that can cause large-scale detriment. Therefore, the recommendations given are that the protection of spawning and nursery areas, as well as the control of aquaculture waste, should be prioritized to minimize pressure on fishery resources.

Abstract

Lembongan Island and Perancak are two areas located in Bali Province that have mangrove ecosystems that are utilized as ecotourism areas with different geomorphologies. This study was conducted with the aim to determine the density and spatial distribution of gastropods and their relationship with environmental characteristics using a multivariate analysis approach i.e., Correspondence Analysis (CA) and Principal Component Analysis (PCA). Sampling used a purposive sampling method consisting of 3 zones based on distance from the sea, namely the sea, middle and land zones. The results showed that the most gastropod species in Lembongan Island were found in the sea zone with 17 which the most gastropod species is Pyrene ocellata, while in Perancak the most gastropod species were found in the middle zone with 13 which the most gastropod species is Sphaerasiminea miniata. Environmental characteristics such as temperature, pH, ORP, salinity and dissolved oxygen still support the survival of gastropods. There is twelve mangrove species have found, were Rhizopora stylosa, Rhizopora apiculata, Rhizopora mucronata, Rhizopora lamarckii, Bruguiera gymnorrhiza, Ceriops tagal, Avicennia marina, Avicennia alba, Avicennia rumphiana, Avicennia officinalis, Sonneratia alba, and  Xylocarpus granatum.

Abstract. Darus RF, Bengen DG, Zamani NP, Ismet MS. 2024. Using morphometric characters to estimate leaf productivity of seagrass Halophila major. Biodiversitas 25: 4994-5004. Halophila major is a seagrass species with new records in Indonesia. This species was described based on morphometric characteristics and DNA sequencing. In this study, we expand our understanding about this species by looking at its leaf productivity. This study aims to determine the productivity of H. major leaves collected across various locations of Indonesian waters and analyses its relationship with morphometric characters. Morphometric characters (Leaf Length-LL, Leaf Width-LW, and Leaf Area-LA) were used to see the correlation with leaf productivity parameters, namely Leaf Dry Weight (LDW), Specific Leaf Area (SLA), Biomass (BIO), and Carbon Concentration (CS) estimated using allometric methods. The result of this study indicates that the biomass of H. major is greater than H. ovalis, its closest relative. LL and LW were more strongly correlated with LDW compared to LA. Biomass was also greatly influenced by LL and LDW. Leaf productivity variation is affected by the leaf size, suggesting that leaf productivity can be used to distinguish seagrass species under the similar genus. This study showed that allometric equations can be used quickly to assess the biomass of small seagrasses. However, more data is needed for knowing and interpreting a character in new seagrass species. Hence, this study must be replicated for other seagrass species.

Abstract. Putra RD, Siringoringo RM, Abrar M, Puranamasari NW, Bengen DG, Zamani NP, Subhan B, Aji LP, Giyanto, Almanar IP, Dollu EA. 2025. Reef fish resilience following a significant earthquake disaster in the Nias Islands, Indonesia. Biodiversitas 26: 1836-1845. The geological upheaval of the Nias Islands, Indonesia, due to a major earthquake in 2005, resulted in lithospheric shifts, causing a sea floor uplift of approximately 1-2 meters. This uplift led to localized coral mortality, posing a threat to certain reefs and consequently impacting the composition of coral reef fishes. This study aims to explore the enduring changes in coral reef fish composition before and after the earthquake. Underwater Visual Census (UVC) transect surveys were conducted using standard SCUBA diving equipment to quantify fish abundance and biomass in benthic substrate transect locations. The reef fish assemblages categorized into corallivores (Chaetodontidae), herbivores (Acanthuridae, Scaridae, and Siganidae), and carnivores (Haemulidae, Lethrinidae, Lutjanidae, and Serranidae), were studied from eight fish families, with species identification conducted at the individual level. Analysis of corallivorous fish abundance during the pre-earthquake period (2004), earthquake event (2005), and post-earthquake recovery (2007-2010) revealed no significant differences (Kruskal-Wallis, p: 0.58). Corallivore abundance was lower in the pre-earthquake conditions, increased during the earthquake (Pairwise Wilcoxon test, p-value: 0.74), decreased in 2007 (Pairwise Wilcoxon test, p-value: 0.071) after the disturbance, but rebounded in 2008 (Pairwise Wilcoxon test, p-value: 0.23). Post the seismic event in 2005, ecological indices reflecting Shannon diversity (H’) and Uniformity Index Evenness (J) among reef fish, especially the corallivore group, consistently displayed a noticeable decline. However, recovery progress levels were exclusively regained by 2010.
