inter- and intra-population variations of a recently described endemic cyprinid fish alburnoides qanati coad and bogutskaya, 2009 collected from three localities in the kor river basin, iran, were studied by applying morphometric and meristic characters using canonical discriminate function analysis (dfa), principal component analysis (pca) and cluster analysis (ca). in dfa, the overall random ...

This study describes proboscis morphology and identifies morphometric differences among five species of noctuid moths with different feeding habits (fruit versus nectar-feeding). Morphological and morphometric parameters were analyzed using scanning electron microscopy and light microscopy. Measurements included: galea height in ten sites from base to tip, total proboscis length, and length of ...

Seventeen morphometric and seven meristic body characteristics were examined in 406 specimens of damselfish (234 females and 172 males) caught in the middle Adriatic (near the Korčula and Kopište Islands). The differences between the mean values of the measured morphometric characteristics in the males and females were not statistically significant. Modes were identical in males and females for...

Knowledge on the fish species is important in habitat protection management. This study was conducted to compare the morphological characteristics of two populations of Rhinogobius similis from Hariroud basin based on landmark morphometric truss network system. A total of 60 individuals from Polkhatoun (30 specimens) and Tafrihgah dam (30 specimens) stations were caught by electrofishing 220 vo...

the genus allactaga is a group of rodents with five morphospecies distributed in the iranian plateau. in order to conduct a taxonomic revision at the species level, 27 individuals were collected in the iranian plateau from localities typical of each species. phylogenetic relationships within species were analyzed using cytochrome oxidase subunit i and morphometric data. maximum parsimony, maxim...

Two dimensional slope profile morphometric investigation in a part of the land failure prone Garhwal region of the Lesser Himalaya, Tehri district, U. P., India, indicates that the landslip morphology is closely related to the dominant movement processes active in this terrain. Technique developed for the morphometric analysis of landslips involves the use of five morphometric indices. Each ind...

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...

introduction management principles predominated on the development and evolution stages of the geomorphic landscapes are different. this is because of variability in landscape evolution, its relationship with other system components and its response to environmental changes and feedback. one of the most important methods of management of geomorphic landscape is the study and evaluation of morph...

This study was conducted to investigate morphometric variation and differentiation in common kilka (Clupeonella cultriventris) caught from Amir Abad and Babolsar fishing ports during winter 2013. Totally, 330 specimens (272 specimens from Amir Abad port and 58 specimens from Babolsar port) were caught by lift net and 30 absolute morphometric traits, 9 meristic traits, length and gonad, body wei...
