Objective- The aim of this study was to determine the normal ultrasonographic and morphologic appearance of mammary gland and teat in Caspian mares during lactation and dry period. Design- Experimental study. Animals- Seven mature Caspian mares Procedures- Using a 6.5-8.5 MHz linear transducer the ultrasonographic appearance of lactating and dry mammary glands was determined in 7 mature Casp...

Russian ( ), Persian ( ) and Siberian ( Acipenser gueldenstaedtii A. persicus A. ) sturgeons are closely related ‘Ponto-Caspian’ species. Investigation of baerii their population structure is an important problem, the solution of which determines measures for conservation of these species. According to previous studies, ‘baerii-like’ mitochondrial genotypes were found in the Caspian Sea among 3...

Current taxonomy of western Eurasian trout leaves a number of questions open; it is not clear to what extent some species are distinct genetically and morphologically. The purpose of this paper was to explore phylogeography and species boundaries in freshwater and anadromous trout from the drainages of the Black and the Caspian Seas (Ponto-Caspian). We studied morphology and mitochondrial phylo...

The rapid rise of Caspian Sea water level (about 2.25 meters since 1978) has caused much concern to all five surrounding countries, primarily because flooding has destroyed or damaged buildings and other engineering structures, roads, beaches and farm lands in the coastal zone. Given that climate, and more specifically climate change, is a primary factor influencing oscillations in Caspian Sea ...

Russian ( Acipenser gueldenstaedtii), Persian ( A. persicus) and Siberian ( A. baerii) sturgeons are closely related 'Ponto-Caspian' species. Investigation of their population structure is an important problem, the solution of which determines measures for conservation of these species. According to previous studies, 'baerii-like' mitotypes were found in the Caspian Sea among 35% of Russian stu...

We present here the findings from a study of the microbiome of the southern basin of the Caspian Sea, the largest water body on Earth disconnected from any ocean and a brackish inland sea. By high-throughput metagenomics, we were able to reconstruct the genomes of representative microbes. The gross community structure (at the phylum level) was different from the structure of typical marine and ...

BACKGROUND Main objective of this study was to investigate the invasive activity of the liver fluke, Pseudamphistomom truncatum against the Caspian seal (Pusa caspica) and was exemplified at the gross, light microscopy (LM) and electron microscopy (EM) levels. METHODS The study was done on a freshly dead Caspian Seal in the southern coast of Caspian Sea. The checked Caspian seal probably bein...

Extraction and transportation of oil in the Sea are one of the pollution sources in the Seawater. Caspian Sea contains about 100000 million barrels of oil. It also contains over 35000 millions cubic meter of flue gas. Daily extractions of crude oil and gas and transportation of them are the main pollution sources of the Caspian Sea. Many truck to carry goods and oil tankers to carry oil from po...
