The Caspian Sea and its basin (e.g. Anzali wetland) is one of the natural habitats of wild common carp Cyprinus carpio. In this study the genetic structure of this species. In the south-west of Caspian Sea (the Anzali wetland) was investigated using PCR-RFLP analysis of D-loop region. Two hundred of mature fish were collected from 5 stations (40 individuals from each station) including Siahkesh...
Ceratium hirundinella is considered as a biological indicator in the environmental and climate changes. In the summer of 2018, the presence of Ceratium hirundinella reported in the Iranian region of the Caspian Sea. So the present study conducted to survey trend of Ceratium hirundinella fluctuations in the Iranian basin of the Caspian Sea during the last 3 decay. The study showed that in the wi...
Although hypersaline environments pose challenges to life because of the low water content (water activity), many such habitats appear to support eukaryotic microbes. This contribution presents brief reviews of our current knowledge on eukaryotes of water-column haloclines and brines from Deep Hypersaline Anoxic Basins (DHABs) of the Eastern Mediterranean, as well as shallow-water hypersaline m...
The present study aimed to survey heavy and toxic metal pollution (lead and cadmium) in the southern Caspian Sea basin through Liza aurata using geographic information system (GIS). Samples of the gill tissue of adult Liza aurata were taken in 10 stations over the southern coast of the Caspian Sea in spring and fall. Interpolation method, Kennedy density function, Moran test, and Gi* index in ...
This article provides a background for scientists interested in a general overview of the geology and geomorphology of Turkmenistan.
