از آنجا که شاخصهای انتخاب زیستگاه در ارائۀ ویژگیهای زیستگاهی یک گونه و برنامههای حفاظتی به کار برده میشود، این مطالعه بهمنظور بررسی ترجیح زیستگاهی گونۀ گل چراغ، Garra rufa در رودخانۀ دینورآب (استان کرمانشاه)، یک سرشاخۀ حوضۀ رودخانۀ کرخه به اجرا درآمد. به اینمنظور، ویژگیهای زیستگاهی شامل عمق آب، سرعت جریان آب، عرض رودخانه، عرض ناحیۀ پتامال (ناحیۀ حاشیۀ رودخانه)، نوع غالب پوشش سنگ بستر، pH، دما، هدایت الکتریکی (EC)، کل مواد جامد محلول (TDS) در 18 ایستگاه از پایین‌دست به سمت بالادست اندازهگیری و ثبت شدند. محدودۀ استفادهشده و محدودۀ زیستگاه انتخابی با توجه به میزان در دسترس بودن هر واحد زیستگاهی برای هر متغیر بهدست آمد. نتایج نشان داد دامنۀ مطلوبترین عمق 30>-26 سانتیمتر با شاخص مطلوبیت 779/0، شاخص عرض رودخانه در دامنۀ 2/7>-6 متر با شاخص مطلوبیت 7/0، سرعت جریان در دامنۀ 31/0>-24/0 متر بر ثانیه با شاخص مطلوبیت 38/0، ساختار بستر با قطر متوسط در دامنۀ 5/5>-5 سانتیمتر با شاخص مطلوبیت 1، دمای آب دامنه 19>-18 درجۀ سانتیگراد با شاخص مطلوبیت 618/0، pH در دامنۀ 44/7>-32/7 با شاخص مطلوبیت 545/0، EC آب در دامنۀ 310>-290 با شاخص مطلوبیت 767/0، TDS آب در دامنۀ 610>-580 ppm با شاخص مطلوبیت 712/0 و عرض ناحیۀ پتامال در دامنۀ 6>-8/4 متر با شاخص مطلوبیت 634/0 بود. نتایج نشان داد رودخانۀ مورد مطالعه برای گونۀ Garra rufa یک زیستگاه با مطلوبیت متوسط است.
