Flow refugia, locations that maintain substrate stability and low hydraulic stress during periods of high flow, can ensure riverine resilience in the face increasing hydrological unpredictability. Despite their known importance, they have been overlooked recent years with work on drought refugia currently seeing greater attention. Moreover, research role flow artificial flood pulses regulated r...
چکیده بهمنظور مطالعه و شناسایی فون ماکروبنتوزهای چشمه دادین کازرون واقع در جنوب غربی فارس در ایران از فروردین تا اسفند سال 1393، نمونهگیری از پنج ایستگاه مختلف چشمه شامل مرکز، شمال، جنوب، غرب و شرق چشمه انجام گردید. نمونهبرداری از رسوبات با استفاده از گرب مدل ون وین انجام شدند. پس از شستشوی رسوبات برای جلوگیری از فساد موجودات زنده با استفاده از فرمالین یک درصد تثبیت و سپس شناسایی ماکروبنتوزه...
a In the 1980s an explosive increase o f the introduced Nile perch (Iates sp.; Harrison 1991) in Lake Victoria caused the destruction o f approximately 65% of the endemic haplochromine cichlid~ The eradication o f approximately 200 vertebrate species in less than a decade may well represent the largest extinction event among vertebrates during this century. The introduction o f the Nile perch c...

Deciphering evolutionary processes occurring within contaminated populations is important for the ecological risk assessment of toxic chemicals. Whereas increased tolerance to contaminants is well documented in aquatic animal populations, whether such phenotypic changes occur through genetic adaptation is still debated. In that sense, several studies with the freshwater crustacean Gammarus conc...
