Abstract

The Halmahera Walking Shark (Hemiscyllium halmahera) is an endemic species in the Halmahera Sea. Information related to the environment in general has not been described in a complex manner. The environment is the main factor to support the life of biota. Environmental characteristics are a determining factor in the sustainability of biota. The study aims to provide information related to the physical environment of the habitat of the H. halmahera species. Primary data collection was carried out directly (in situ). Current data was taken using the Lagrange method using a currents drogue. Tides using tidal palms and observed for 24 hours. Secondary data was taken from Marine Copernicus and the Geospatial Information Agency (BIG). All data were tabulated and analyzed by Ocean Data View (ODV) software. The results of the study found that the surface current velocity was found to be in the fast current category. Current speed descriptively provides information on the life of H. halmahera. Primary data shows that the direction of the surface current moves to the east and north. Secondary data in vertical distribution shows weak zonal and meridional current shifts. The tidal pattern was found to be two high and low tides (semidiurnal). The distribution of surface temperature was found to be around 30-32oC. The vertical temperature profile found three layers, namely 1-13m (30oC), 65m (25oC) and 71m (20oC). The chemical environment showed all normal variables. The physical and chemical environmental conditions support H. halmahera to inhabit the sea area of Morotai Island. The environmental description has provided a brief understanding of how the ecological role of the H. halmahera species. Management and sustainability of the environment in the future due to climate change can be done with information on habitat characteristics.Keywords:coral triangleHalmaheranicheNorth Malukutropical

Abstract

Graphical Abstract Highlight Research 1. This research provides initial and current information regarding seagrass on small islands right on the equator. 2. directly depicts the diversity, density and cover of seagrass in a unique region, namely a small island crossed by the equator. 3. The environmental conditions of marine waters in seagrass areas on islands crossed by the equator have been described. 4. The latest information specifically describing seagrass and the ecology of equatorial marine environments. Essential for the development of future knowledge and technology. 5. DNA barcoding was capable of resolving field identification challenges and providing taxonomic clarification based on DNA sequence data.   Abstract Equatorial small islands host dynamic coastal ecosystems, yet seagrass biodiversity and molecular identification remain poorly documented. Complete information on coastal ecosystems has not been provided for seagrass in the equatorial latitudes. Seagrass is dynamically distributed throughout the equatorial latitudes. The area that the equatorial latitudes also traverse is known as the indotropic region. Eastern Indonesia’s Kayoa Island is situated directly on the equator. However, seagrass biodiversity and DNA-based species confirmation in this region remain insufficiently documented. There are no published research on seagrass, particularly on biodiversity. The aim of this study is to reveal the diversity of seagrass in equatorial latitudes on the small islands. The methodology in this study was purposive sampling with a quadrant line transect was used to obtain the samples. In situ identification of seagrass species was done. Seagrass samples were taken from the leaves for DNA analysis purposes. Leaf samples were analyzed using molecular methods in the laboratory. To determine the distribution of seagrass ecology and environmental were subjected to PCA analysis. The results showed that six seagrass species were identified. It has been discovered that seagrass may develop in the tropical region under typical environmental conditions. Despite the fact that six species were discovered, diversity was limited. In this region, seagrass cover is typically high and supports a healthy species density. Species diversity was low, whereas percent cover and density were locally high. Overall, the study indicated relatively low diversity and density values. DNA barcoding has revealed differences in morphological identification.This discovery represents preliminary data that can be investigated further in subsequent studies.

Abstract

Noctiluca scintillans is a mixotrophic dinoflagellate commonly associated with eutrophic coastal systems and bloom dynamics. This study aims to characterize the morphometric variability of N. scintillans in Jakarta Bay, a tropical coastal environment strongly influenced by anthropogenic nutrient enrichment, and to evaluate how cellular morphology reflects functional and ecological responses under eutrophic conditions. Plankton samples were collected in February 2024 and analyzed using high-resolution microscopy to quantify key morphometric traits, including cell diameter, biovolume, aspect ratio, surface area-to-volume (SA:V) ratio, and nucleus-to-cytoplasm (N:C) ratio. Differences between red (RNS) and green (GNS) morphotypes were assessed using non-parametric statistical analyses, and preserved measurements were corrected to estimate live cell size. A total of 121 cells were analyzed, with RNS overwhelmingly dominating the population. RNS exhibited significantly larger cell diameter and volume than GNS, while SA:V ratios differed significantly between morphotypes, indicating functional differences in size-related morphology. In contrast, aspect ratio did not differ significantly, suggesting overall conservation of cell shape across morphotypes. Estimated live cell sizes indicate that N. scintillans populations in Jakarta Bay are dominated by relatively small cells compared to those reported from temperate regions. Variability in the N:C ratio further suggests heterogeneity in cellular physiological states within the population. Overall, these findings establish a morphometric baseline for N. scintillans in Jakarta Bay and highlight the value of morphometric traits as integrative indicators of physiological variability and environmental forcing in tropical eutrophic coastal systems.

Abstract

Soft corals of the genus Clavularia (Blainville 1830) have complex and difficult to distinguish morphological characteristics, making them rather difficult to identify. A paucity of information exists for Indonesian coral reefs, a complex biogeographic region at the confluence of the Pacific and Indian Ocean that covers an extensive geographic area and several marine ecoregions, is subject to several ocean current systems, and includes a high diversity of habitats. Specimens of Clavularia inflata were collected from eleven study sites across the Indonesian archipelago, morphologically described based on their sclerite characteristics, and compared among sites. Sclerite observations were divided into four parts for each colony, namely pinnules, crowns, calyces, and stolons. The sclerites found in C. inflata comprised various forms such as rods, fingers, sticks, and brackets. Morphometric measurements of C. inflata showed specimens from Kepulauan Seribu had the largest pinnule, calyx, and stolon sclerites compared to other locations. The maximum mean size of crown sclerites was observed for specimens from Maluku Tenggara Barat. Similarities in the shape of sclerites resulted in specimens from Kangean, Morotai, Tanjung Lesung, Bontang, Lombok and Natuna forming a cluster, while those from Maluku Tenggara Barat and Arborek were dissimilar to other sites. Smaller sclerite sizes in specimens from Arborek are likely related to strong currents at that site. In conclusion, there were variations in the size of sclerites across the eleven study sites, with several sites forming a cluster of similar sclerite dimensions. Further studies using molecular markers are suggested to further explore the possibility of cryptic species.

Abstract

Restorasi terumbu karang adalah serangkaian upaya ilmiah dan manajerial untuk memulihkan ekosistem terumbu karang yang rusak akibat faktor alam dan aktivitas manusia. Teknik restorasi yang digunakan termasuk transplantasi karang, pembuatan terumbu karang buatan, dan pengendalian stresor lokal seperti polusi, overfishing, dan perubahan iklim. Kegiatan restorasi di Indonesia telah dilaksanakan di lebih dari 500 titik dalam 30 tahun terakhir, melibatkan ribuan unit terumbu buatan dan jutaan fragmen karang. Namun, banyak dari kegiatan ini tidak menunjukkan keberhasilan yang ditandai dengan kegagalan.  Faktor peningkatan suhu laut, persaingan dengan alga atau spons, serta faktor manusia menjadi penyebab utama. Saat ini, Indonesia belum memiliki standarisasi untuk menilai keberhasilan restorasi terumbu karang. Oleh karena itu, penting untuk mengembangkan parameter dan indikator yang dapat digunakan untuk menilai efektivitas dan keberhasilan kegiatan restorasi, guna memastikan keberlanjutan ekosistem terumbu karang.

DNA barcoding and phylogeneticreconstruction of shark species landed in Muncar fisheries landing site in comparison with Southern Java fishing port. Biodiversitas 16:55-61. Sharks are one of main fisheries commodity that are currently exploited on a large scale because of their high economic value.The identification of sharks has been a difficult one due to the specimen’s similarity in morphology and mostly have had key diagnosticfeatures removed. This study aimed to identify and to review the status of sharks, and also to reconstruct the shark species that werelanded at South Java fishing port using molecular approaches. The DNA amplification was using cytochrome oxidase I mitochondrial oflocus and 600-700 basepairs. A total of seven species from 59 individuals was identified including Alopias pelagicus, Carcharhinusfalciformis, C. sorrah, C. amblyrhynchos, Galeocerdo cuvier, Atelomycterus marmoratus, and Spyrna lewini. The diversity of sharkspecies landed in Muncar during the last 2 years has been decreased. The identified sharks species in this study sites were about 18% ofall Indonesian sharks. The result of this study is expected help the Government to manage shark fisheries in Indonesia.

Abstract

Madduppa HH, Subhan B, Suparyani E, Siregar AM, Arafat D, Tarigan SA, Alimuddin, Khairudi D, Rahmawati F, Bramandito A. 2013. Dynamics of fish diversity across an environmental gradient in the Seribu Islands reefs off Jakarta. Biodiversitas 14: 17-24. The reefs of Seribu Islands have been affected by multitude of anthropogenic pressures. However, the biodiversity of reef fishes across the archipelago linked to environmental condition is poorly known. This study aimed to investigate the biodiversity and the trophic level of fish communities across the archipelago. The study on reef fish communities was conducted on 33 reef sites associated with islands or shoal randomly chosen from each zone along environmental gradients from the inshore water nearest of Jakarta Bay to the offshore water of the outer islands. The study sites represented each sub-districts within the archipelago, namely Pari, Tidung, Panggang, Kelapa, and Harapan. A total of 46,263 individual fishes were counted, belonging to 216 species and 29 families. The multivariate analysis of fish abundance using the Bray Curtis similarity index and non-metric multidimensional scaling (MDS) clearly showed the clustering of sub-districts, near and far from Jakarta Bay. The results showed that the sub-districts can be clustered into three groups. Group one consists of one sub-district (Pari) located in the southern part of the Seribu Islands near Jakarta Bay. Group two consists of three subdistricts (Tidung, Panggang, Kelapa) located in mid of the archipelago. The third group consists of one sub-district (Harapan) located in the northern part of the Seribu Islands. Based on species richness and fish diversity indices, the sub-districts can be clustered into two groups (1 = Pari and Tidung, 2 = Panggang Kelapa, Harapan). However, levels of similarities among sub-districts varied. The fish community in sub-district of Pari was dominated by carnivorous, omnivorous and herbivorous fishes, while those in the rest of subdistricts were dominated by omnivorous and carnivorous fishes. The present study results showed that the biodiversity of reef fishes across the Seribu Islands seemed to be linked to the environmental conditions.
