The conservation of migratory species poses significant challenges that may be countered by detailed knowledge about the sites used migrants throughout annual cycle. We present first GPS-tracking data on migration declining Caspian terns Hydroprogne caspia breeding in Baltic Sea. For 39 from colonies along a latitudinal gradient 57 to 65°N, we identified key routes, stopovers and wintering area...

The present work was conducted to investigate the chemical composition (amino acid, mineral content, and lipid profile) of bones from three different Iranian pelagic fish species. The biochemical composition of Sardinella gibbosa, Clupeonella engrauliformis and Stolephorus indicus bones captured from the Iranian Ocean (the Oman Sea and Caspian Sea) were determined. The analysis of amino acids a...

The big eye kilka, Clupeonella grimmi, is a marine fish living in depth of 20 to 200 meter of the Caspian Sea. Its eye and retina were processed for histological and SEM studies. Paraffin embedded retina was cut radially and tangentially in 5 ?m thickness and stained with hematoxylin and eosin method. The unstained sections were manipulated for SEM image observations. Tangential retinal sect...

As rickettsioses may be severe diseases and Rickettsia prowazekii is a potential agent of bioterrorism, highly efficient diagnostic techniques are required to detect rickettsiae in patients. We developed a nested PCR assay using single-use primers targeting single-use gene fragments present in the genomes of both Rickettsia conorii and R. prowazekii. We used this "suicide" PCR with DNA from 103...
