. In this study, morphological variation of three species of Squalius in Iranian basins was studied. For this purpose, 709 specimens were captured from the Caspian Sea, the Urmia Lake, the Namak Lake and the Tigris basin. After anesthetizing in clove oil solution and fixing in 10% neutralized formalin, specimens were transferred to the Isfahan University of Technology Ichthyology Museum (IUT-IM...
Abstract This paper presents a robust approach using artificial neural networks in the form of a Self Organizing Map (SOM) as a semi-automatic method for analysis and identification of morphometric features in two completely different environments, the Man and Biosphere Reserve “Eastern Carpathians” (Central Europe) in a complex mountainous humid area and Yardangs in Lut Desert, Iran, a hyper...
in this study, by examining the character of the morphometric and meristic characters of garra variabilis samples which is obtained from different locality in tigris river, morphometric characters which are transformed, subjected to discriminant analysis and depending on grouping model, number of discriminant functions and according to importance of these in terms of explaining total variance, ...
Background and purpose: Dicrocoeliasis is a prevalent parasite in ruminants caused by different species of Dicrocoelium spp. This parasite lives in bile duct and gallbladder of ruminants and accidentally in human. The economic significance of dicroceliasis is due to direct damage to the liver and, consequently, to the loss of significant amounts of protein. The present study aimed to investigat...
