The anatomy, histology and ultrastructure of the digestive tract of Orthrias angorae (Steindachner, 1897) were investigated using light microscopy, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The histological structure consists of four layers: mucosa, submucosa, muscularis and serosa. The esophageal mucosa consists of undifferentiated basal epithelial cells, m...
This study was conducted to determine ichthyofauna of the Büyük Karaçay stream of the River Orontes drainage in Turkey (eastern Mediterranaen basin). As the result of examination of the 911 individuals collected between June 2012 and May 2013, eight fish species belonging to five families have been recorded. Of these, African catfish Clarias gariepinus (Burchell, 1822), yellow barbel Carasobarb...
This study was conducted to provide length-weight (LWRs), length-length (LLRs) relationships and condition factor of Oxynoemacheilus seyhanensis from seven habitats belonging three inland water basins Turkey. A total 166 specimens were collected Yıldızeli, Taşköprü, Suşehri (Kızılırmak basin), Büyükpotuklu, Pınarbaşı Örenşehir (Seyhan basin) Akdağmadeni (Yeşilırmak rivers during 2017-2019. The ...
this study provides new data on chromosomal characteristics and dna barcoding of three endemic loaches of iran: spiny southern loach cobitis linea (heckel, 1847), persian stream loach oxynoemacheilus persa (heckel, 1848) and tongiorgi stream loach oxynoemacheilus tongiorgii (nalbant & bianco, 1998). the chromosomes of these fishes were investigated by examining metaphase chromosome spreads ...
سه نشانگر ریزماهواره کاملا متفاوت بمنظور بررسی تنوع و ساختار ژنتیکی سه جمعیت ماهی oxynoemacheilus argyrogrammaدر رودخانه¬هایاستان¬های کرمانشاه و کردستان مورد استفاده قرار گرفت. در کل تعداد 90 نمونه از سه منطقه جمع آوری شد. هر سه نشانگر ریزماهوراه مورد استفاده در این تحقیق پلی مورفیسم کافی را نشان دادند. در مجموع 36 الل برای سه جایگاه مورد استفاده بدست آمد. تعداد الل در هر جایگاه در محدوده 17– 6...
Lake Van is the largest saline soda lake in world and one of world’s few endorheic lakes greater than 3,000 km 2 surface area. Despite its huge size, no fish species have so far been known to permanently occur this due extreme environmental conditions. Here, we report discovery a population that inhabits some unique microbialites lake, at maximum depth 13 m about 500 offshore. We tested whether...
Information on density and abundance of globally threatened species such as tigers Panthera tigris is essential for effective conservation as well as to evaluate the success of conservation programmes. We monitored tigers in Parsa Widlife Reserve, Nepal, using camera traps, in , and . Once believed to be a sink for tigers from adjacent Chitwan National Park, Parsa now provides a ne...
Faeces provide relevant biological information which includes, with the application of genetic techniques, the sex and identity of individuals that defecated, thus providing potentially useful data on the behaviour and ecology of individuals, as well as the dynamics and structure of populations. This paper presents estimates of the sex ratio of different felid species (jaguar, Panthera onca; pu...
