این مطالعه باهدف توصیف ویژگی های استخوان شناسی سگ ماهی خاردار فرید پاکی cobitis faridpaki و مقایسه آن با گونه c. taenia به اجرا درآمد. نتایج این تحقیق برخی اطلاعات در مورد ویژگی های زیست شناسی این گونه بومی جدیداً معرفی شده و همچنین ویژگی های قابل اعتمادتر استخوان شناسی برای شناسایی آن را فراهم خواهد آورد. بدین منظور، تعداد 20 نمونه سگ ماهی خاردار فرید پاکی از رودخانه سیاه رود توسط الکتروشوکر نم...
This study was carried out in the inland waters of Muğla Basin between 2018-2019. As a result field studies and literature, it determined that there were 36 species fish belonging to 17 families (Anguillidae, Atherinidae, Cobitidae, Leuciscidae, Cyprinidae, Gobionidae, Nemacheilidae, Aphaniidae, Poeciliidae, Blenniidae, Centrarchidae, Cichlidae, Gobiidae, Moronidae, Mugilidae, Salmonidae, Silur...
Taxonomic investigation of spined loaches from Dalmatia and Herzegovina was conducted on specimens from 14 localities. The results of the detailed morphological investigations were combined with genetic data (based on one mitochondrial and two nuclear genes) in order to resolve the taxonomic status of each Cobitis population. Among the investigated features of external morphology, the appearanc...
Loach minnow (Rhinichthys cobitis) and spikedace (Meda fulgida) are legally protected with the status of Endangered under the U.S. Endangered Species Act and are endemic to the Gila River basin of Arizona and New Mexico. Efficient and sensitive methods for monitoring these species' distributions are critical for prioritizing conservation efforts. We developed quantitative PCR assays for detecti...
به منظور تعیین تنوع زیستی، فراوانی و پراکنش گونه ماهیان موجود در رودخانه دینورآب اقدام به تعیین حداقل ۳ ایستگاه در مسیر رودخانه شده است. نمونهبرداری بصورت فصلی انجام و نمونههای صیدشده پس از انتقال به آزمایشگاه، با استفاده از کلید شناسایی معتبر تا حد گونه شناسایی شدند. در این تحقیق 19 گونه ماهی شامل ۴ خانواده (Cyprinidae)، (Nemacheilidae) ،(Cobitidae) (Poeciliidae) نمونهبرداری شد که متعلق ب...
Given the hybrid genomic constitutions and increased ploidy of many asexual animals, the identification of processes governing the origin and maintenance of clonal diversity provides useful information about the evolutionary consequences of interspecific hybridization, asexuality and polyploidy. In order to understand the processes driving observed diversity of biotypes and clones in the Cobiti...
The region of Balkans is often considered as an ichthyologic "hot spot", with a great number of species and high portion of endemics living in fresh waters in a relatively small area. The Adriatic watershed in Croatia and Herzegovina is inhabited by six spined loach species (genus Cobitis) whose extinction risk estimations were based solely on their extent of occurrence (and/or area of occupanc...
Gobies and their ectoparasitic monogenean flatworms are promising models for species diversification because of richness. Recent decades have seen the discovery several new Gyrodactylus (Monogenea: Gyrodactylidae) on European gobies, mostly in sand goby lineage especially eastern Mediterranean. However, fauna other gobies is much less understood. Therefore, we inspected five gobiid (34 specimen...
