Keberadaan dan kelimpahan gastropoda bivalvia sangat ditentukan oleh adanya vegetasi mangrove yang ada di daerah pesisir. Tekanan perubahan lingkungan dapat memengaruhi jumlah jenis perbedaan struktur dari bivalvia. Tujuan penelitan ini yaitu untuk mengetahui kepadatan ekosistem mangrove, komunitas serta kualitas perairan pada Perairan Desa Pangkil. Penelitian dilakukan bulan Juli-Agustus 2021....

Pulau Merah merupakan kawasan wisata pantai di Banyuwangi yang memiliki zona intertidal wilayah pantainya. Pada terdapat biota laut tinggal disana, salah satunya dari kelas bivalvia belum diketahui kelimpahan populasinya. Tujuan penelitian ini untuk mengetahui populasi moluska bivalvia. Metode digunakan pada dengan menggunakan transek line kuadrat disesuakan luas meliputi panjang garis dan reli...

Chemoautotrophic endosymbionts are the metabolic cornerstone of hydrothermal vent communities, providing invertebrate hosts with nearly all of their nutrition. The Calyptogena magnifica (Bivalvia: Vesicomyidae) symbiont, Candidatus Ruthia magnifica, is the first intracellular sulfur-oxidizing endosymbiont to have its genome sequenced, revealing a suite of metabolic capabilities. The genome enco...

Tellidorella (type species: T. cristulata) is a small eastern Pacific bivalve presently classified in the Cardiniidae, a family otherwise known as fossils from the Paleozoic and early Mesozoic. Evidence from shell characters including external sculpture, hinge teeth, and adductor muscle scars suggests a more appropriate placement in the subfamily Myrteinae of Lucinidae. This is the first record...

The ecosystem of the Caspian Sea have been strikingly changed by human activities. This area has undergone significant ecological alterations and serious environmental degradation since the beginning of 1990s. The impact of fish cage culture on the zooplankton community was studied in the southwestern Caspian Sea, off Jafrud during January to April 2013. A total of 12 zooplankton belonging to 9...

Fauna Europaea provides a public web-service with an index of scientific names (including important synonyms) of all living European land and freshwater animals, their geographical distribution at country level (up to the Urals, excluding the Caucasus region), and some additional information. The Fauna Europaea project covers about 230,000 taxonomic names, including 130,000 accepted species and...

Five lotic systems of Serra do Cipó, south-east Brazil, were investigated in order to assess the existing diversity of benthic macroinvertebrates, habitats-microhabitats, and the available trophic resources. For each river it was analysed the communities of benthic macroinvertebrates and the composition of some taxonomic groups (Plecoptera, Ephemeroptera, Trichoptera and Diptera Chironomidae): ...

Interand intra-specimen variability masks reliable temperature control on shell Mg/Ca ratios in laboratory and field cultured Mytilus edulis and Pecten maximus (bivalvia) P. S. Freitas, L. J. Clarke, H. A. Kennedy, and C. A. Richardson School of Ocean Sciences, College of Natural Sciences, Bangor University, UK Departamento de Geologia Marinha, INETI, Portugal Received: : 29 November 2007 – Acc...

Revived interest in molluscan phylogeny has resulted in a torrent of molecular sequence data from phylogenetic, mitogenomic, and phylogenomic studies. Despite recent progress, basal relationships of the class Bivalvia remain contentious, owing to conflicting morphological and molecular hypotheses. Marked incongruity of phylogenetic signal in datasets heavily represented by nuclear ribosomal gen...
