Described is Melita mirzajanii n. sp. (Melitidae) from the southwestern corner of the Caspian Sea. It shows no particular similarity to any species known from the Mediterranean Sea. It inhabits, as the only amphipod species, dense growths of Amphibalanus cf. improvisus (Darwin 1854) in a port, at low and highly fluctuating salinities. Its most striking characters are: absence of any pleonal or ...

  The stocks of Caspian roach ( Rutilus rutilus ), an economically important species in the Caspian Sea, is depleting. Annually, millions of fingerlings of these species are produced artificially and restock in the mouth of Qare Soo River in the Southern Caspian Sea, where they exposed to the pesticides coming from rice and orchard farms in the region. The fate of this exposure in hypo-osm...

Ecosystems in the Caspian Sea region have been heavily modified by anthropogenic activities, mainly as a result of changes in the water flow and degradation of the water quality in the ecosystems. Changes in the regional environment have influenced regional economies, particularly obvious in the impacts on fish stocks. Using the methodology developed in the GIWA project, experts in the region c...

feeding habits of caspian marine shad alosa braschnikowii (borodin, 1904), inhabiting in the western part of caspian sea such as prey spectrum and seasonal dynamics have been studied. as in other parts of caspian sea, throughout the year, the main hunt of caspian marine shad constituted kilkas, gobies and shrimps while other groups of zoobenthos were represented in a lesser extent. importance o...

Sea-level changes through the Quaternary era have provided recurrent opportunities for the biosphere to significantly shape the coastal geomorphology of eastern Africa. Key agents in this shaping have been the calcium carbonate-fixing biota that have constructed the oceanfacing fringing reefs and produced the extensive backreef sediments that form the limestone platforms, cliffs and terraces th...

Round goby (Neogobius melanostomus, Pallas 1814) which belongs to Gobiidae, inhabits in the Black Sea, Marmara Caspian Sea and rivers that flows into fore stated seas. The main population parameters, such as age, length, sexual composition, length-weight relationship, growth, condition factor, gonadosomatic index reproduction of N. melanostomus were investigated from coasts southern this study....

Iran is known as the most complex and varied country in southwest Asia, in terms of geography, vegetation, climate and consequently biological diversity. The rather high number of recorded endemic species of Fulgoromorpha in Iran indicates a high potential for speciation in some areas. In this study, in order to identify the endemic zones for Fulgoromorpha of Iran, three main biogeographic regi...

A total of 48 female spirlins Alburnoides sp. from the Kesselian stream (South Caspian Sea basin, northern Iran) were examined during a period from July 2008 to June 2009 to obtain data on fecundity, and to determine the spawning season of this carp. The mean absolute fecundity of females spirlin was 1722.92 (653.88) eggs. The fecundity has positive correlation with the size of the female. The...

The interaction between sea and atmosphere has profound effects on the regions climate. Meanwhile, the sea surface temperature is considered as one of the most effective components of water bodies, and the controller of many atmospheric behaviors. Because of the importance of sea surface temperatures effects on atmospheric elements and also given the role of global warming on land and sea surfa...
