Front. Mar. Sci. 4:196. doi: 10.3389/fmars.2017.00196 Genetic Population Structure and Demographic History of the Wide...
The sampling of fishes and Macrobenthic were performed in Goharbaran Mazandaran province by selecting four stations at a depth of 5 meters and four stations at a depth of 10 meters a monthly basis from May 2013 to April 2014 and fish samples of coastal blade caught were used. During the study, a total of 565902 Macrobenthic invertebrates isolates belonging to 22 species of 9 families. Oligochae...
Huge tsunami waves associated with megathrust earthquakes have a severe impact on shallow marine ecosystems. We investigated the impact of a tsunami generated by the 2011 M9.0 Tohoku-Oki earthquake on the seafloor and large benthic animals in muddy and sandy ria coasts (Otsuchi and Funakoshi bays) in northeastern Japan. We conducted underwater field surveys using scuba equipment in water depths...
Penelitian ini dilakukan pada ketiga pulau kecil yang ada di Bangka Belitung yaitu Pulau Putri, Panjang dan Semujur. Tujuan penelitian adalah untuk mengetahui keanekaragaman bivalvia gastropoda berdasarkan karakteristik masing-masing pulau. Metode digunakan metode Purposive sampling dengan teknik transek garis pengambilan tegak lurus terhadap pantai. Stasiun terdiri dari 3 stasiun 5 plot pencup...
Bivalvia merupakan golongan kekerangan remis, dan sebangsanya. Penelian ini dilaksanakan pada bulan November-April 2022 di perairan Desa Tanjung Pinang, Kecamatan Kusambi, Kabupaten Muna Barat. Analisis tekstur substrat lakukan Laboratorium Perikanan Ilmu Kelautan Universitas Halu Oleo. Pengambilan sampel bivalvia dilakukan dengan dua kali pengulangan dari masing-masing stasiun. meletakan trans...
There is only one exception to strict maternal inheritance of mitochondrial DNA (mtDNA) in the animal kingdom: a system named doubly uniparental inheritance (DUI), which is found in several bivalve species. Why and how such a radically different system of mitochondrial transmission evolved in bivalve remains obscure. Obtaining a more complete taxonomic distribution of DUI in the Bivalvia may he...
This is confirmed that bacteria and other living organisms are not able to decompose or excrete the heavy metals, so heavy metals concentrate and accumulate in their tissues and cause toxicity in other organisms in high levels of food chain via biomagnifications and transfer by organisms to the intermediate levels of food chain for instance macrobenthos. Mean concentration of lead was estimated...
This note is the first communication of the occurrence of the alien Anodonta (Sinanodonta) woodiana (Lea, 1834) (Bivalvia: Unionidae) in Lake Maggiore (Northern Italy). We have found empty shells of the bivalve first in August 2010, and since then, this species is colonizing rapidly the second deepest subalpine lake in Italy. Preliminary findings on morphometric features of A. woodiana in the L...
Reportamos los moluscos asociados a la valva derecha del ostión de roca Striostrea prismatica Gray, 1825. Un total doce valvas preservadas en alcohol al 96% fueron examinadas. Los las separados con ayuda un estereoscopio. Las analizadas tuvieron una longitud mínima 61.1 mm y máximo 84.2 mm. Se cuantificaron 164 valvas, representados por clases Gastropoda Bivalvia, 8 familias, 11 géneros, 12 esp...
In 2018 and 2019, quantitative aquatic macroinvertebrate samplings were carried out in the river network of Bükkösdi-víz (Mecsek Mountain). The identification 325,865 specimens originated from 40 sampling sites resulted occurrences 125 different species belonging to 12 higher taxa (Gastropoda – 9, Bivalvia 1, Hirudinea 4, Malacostraca 6, Ephemeroptera 16, Odonata 12, Plecoptera 3, Heteroptera 1...
