quantifying morphological characteristics of body shape in fishes can help their correct identification as well as understanding of evolutionary history of their different populations. hence, this study was aimed to compare the morphological characteristics of different population of tuini fish (capoeta damascina) in inland-water of iran using geometic morphometrics method (gm). in total 373 sp...

Interrelationships, origin and phylogenetic affinities of brown trout Salmo trutta populations from the southern Caspian Sea basin, Orumieh and Namak Lake basins in Iran were analysed from complete mtDNA control region sequences, 12 microsatellite loci and morphological characters. Among 129 specimens from six populations, seven haplotypes were observed. Based on mtDNA haplotype data, the Orumi...

Interrelations bctwecn drainage area, lake area, length, mean breadth, mean depth, and maximum depth arc examined in 2G2 rock basins and 137 basins lying in or dammed by glacial drift. The effect of lake dimensions upon the time taken for complete water replacement is calculated, and an illustration is given of the influence of lake urea and mean depth upon the tcmpcrature of surface and bottom...

The atmospheric deposition of H+, SO4, and Hg to Little Rock Lake in northern Wisconsin has declined substantially during the past decade. Parallel decreases have been observed in the surface waters of the lake. Here we extend the observations to the fish community and we present evidence of a contemporaneous decline in levels of Hg in fish tissue. By comparing data from two separated basins of...

The manifold role of aquatic macrophytes in lake ecology is closely linked to their distribution and biomass, which in turn is a synergy of various environmental factors. The implication of different environmental variables on macrophyte speciation and life form structure in lake Hiidenvesi, with an uneven eutrophication history, was studied. The persisting life forms refl ected the somewhat in...
