we report observations on the natural history of lizards in the gando protected area, within the sistan and baluchestan province, iran. the identity of the lizards is recorded, along with remarks on some meristic characteristics. brief descriptions of their habitats are also given with a distribution map. lizards (n = 132) were collected and photographed in 2008-09. twelve species belonging to ...

Schizothorax curvifrons is a morphometrically and meristically most variable and economically valuable promising fish food from Kashmir Valley. Since there is a lack of information on stock structure of wild populations on this species, this study was aimed to investigate the intraspecific variation of this important snowtrout. For this, two rivers and one lake in Kashmir Himalaya were sampled ...

Fierce predatory freshwater fishes, the species of Percocypris (Cyprinidae, Teleostei) inhabit large rivers or lakes, and have a specific distribution pattern. Only a single species or subspecies occurs in each large-scale drainage basin of the Southeastern Tibetan Plateau. In this study, the molecular phylogenetic relationships for all but one of the described subspecies/species of Percocypris...

Caudal neurosecretory system is an additional neuroendocrine system found in fishes. Great variation has been observed among different groups of fishes, so far its organization is concerned. Much work has been undertaken on the caudal neurosecretory system of elasmobranchs and teleosts. large size scattered Dahlgren cells in the posterior end of spinal cord, corresponding to last few vertebrae,...
