“…The abundance of species in a community will affect the diversity of ecosystems in the area. The variety of a species will decrease if the number of species and there are variations in the number of individuals of a larger species (Sawitri et al 2019;Duya et al 2021). Diversity (H') in the mangrove ecosystem, especially for the life of saving crabs or burrowing crabs, can be influenced by various factors such as the growth of mangrove vegetation, tides, sound pollution, and vibrations caused by human and natural activities (Sinamo et al 2020;Hasan and Padjadjaran 2021).…”

The Mangrove ecosystem is an ecosystem that is around the edge of the coast and many organisms live in this ecosystem, one of them is crabs. The crabs that are often found are deposit crabs from the Ocypodidae and Sesarmidae families that act as balancers in the mangrove ecosystem. This study aimed to analyze species, diversity, evenness, and dominance in the mangrove vegetation area of Koto XI Tarusan District, West Sumatera, Indonesia. The method used is the descriptive method. The biodiversity of brachyuran crabs’ families, Ocypodidae and Sesarmidae, was analyzed with the Shannon-Wiener index (H’). Four indices were calculated for crabs Ocypodidae and Sesarmidae: species identification, Shannon-wiener (H’) diversity, evenness, and dominance indices. The results showed that there were six species of deposited crabs from the Ocypodidae and Sesarmidae families, namely Uca bellator, U. rosea, Perisesarma eumolpe, P. plicatum, Sarmatium germaimi, and Sesarma curoense. The most abundant species (Di) came from the family Sesarmidae. However, for all stations, diversity (H') has a value that is in the medium category, and evenness (E) is in the high category at each station. The dominance (D) obtained a value categorized as low at each observation station. The condition of environmental parameters in the mangrove vegetation area is included in the category of a good environment. It is still within normal limits for the crabs of the Ocypodidae and Sesarmidae families to live. Two substrate types are found in each observation path: muddy and sandy mud.

The violin crab Uca spp. is a benthic organism that has an ecological role in the mangrove ecosystems. Passo mangrove ecosystem is degraded which can threaten the existence of violin crabs. The study was held in May-June 2023 to analyze the species composition and density of violin crabs. The results of the study can be used as basic data for the violin crabs and their habitat management. The study was conducted at 3 stations using the purposive sampling method. Sampling of violin crabs and substrate structures at each station was carried out at the lowest low tide using the plot method randomly. Data of violin crab species were calcified based on taxon. Data of substrate are classified by presentation of each fraction. Seven species of violin crabs are found in the study namely U. annulipes, U. perplexa, U. vocans, U. mjorbergi, U. lactea, U. dussumieri, and U. vomaris. The total density of violin crabs ranges from 8.1-29.9 ind/m2. The total highest density of violin crab is found in station 1 and lowest at station 2. Species densities differ between stations. The highest species density is U. perlexa (1.4–10.2 ind/m2), and the lowest is U. vomeris (0.0-2.1 ind/m2). Keywords: Uca spp., Mangrove, Habitat, Passo Abstrak Kepiting biola Uca spp. merupakan organisme bentik yang memiliki peranan ekologi pada ekosistem mangrove. Ekosistem mangrove Passo mengalami degradasi yang dapat mengancam keberadaan kepiting biola. Penelitian dilakukan pada bulan Mei - Juni 2023, yang bertujuan untuk menganalisis komposisi spesies dan kepadatan kepiting biola. Hasil penelitian dapat digunakan sebagai data dasar bagi pengelolaan kepiting biola dan habitatnya. Penelitian dilakukan pada 3 stasiun yang ditetapkan menggunakan metode purposive sampling. Sampling kepiting biola dan struktur substrat pada tiap stasiun dilakukan saat surut terendah menggunakan metode plot yang ditempatkan secara acak. Data spesies kepiting biola dikalsifikasikan berdasarkan takson. Data fraksi substrat diklasifikasikan berdasarkan presentasi berat tiap fraksi. Selama penelitian ditemukan 7 spesies kepiting biola yaitu U. annulipes, U. perplexa, U. vocans, U. mjorbergi, U. lactea, U. dussumieri, dan Uca vomaris. Kepadatan total kepiting biola berkisar antara 8,1-29.9 ind/m2. Kepadatan total tertinggi pada stasiun 1 dan terendah pada stasiun 2. Kepadatan spesies berbeda antar stasiun penelitian. Spesies dengan kepadatan tertinggi adalah U. perlexa (1,4-10,2 ind/m2). Spesies dengan kepadatan terendap yaitu U. vomeris (0,0-2,1 ind/m2). Kata kunci: Uca spp., Mangrove, Habitat, Passo

Mangrove ecosystem provides high ecological contribution to various biological resources including fiddler crab, Uca spp in its ecological and economic role in the ecosystem. The study held in September to October 2020 to analyze species composition, density and characteristic of bioturbation (color, substrate structure and the shape). The study was conducted at 3 station using purposive sampling method. The stations are determined based on the characteristic of the fiddler crabs habitats (living status, the vegetation of mangrove, substrate tipes and utilization level). Three species of fiddler crabs are found in the study namely Uca perpelexa, U. lactea, and U. mjoebergi. The highest density is represented by U. perpelexa. The highest density of fiddler crab is found in station 2 with various habitats characteristics. The color of the bioturbation are different in every station considering the substrate structure. Substrate fraction is dominated by sand in various catagories in every station especially on its roughness (rough, medium and soft). Five shapes of bioturbation are found by the study considering the various percentage of total and the various of inhabitant species in every station. The bioturbations are influenced morfologicaly by substrate structure and the existing rooting of the mangrove vegetation.
