Feeding behavior of brown trout, Salmo trutta fario, during spawning season in four rivers of Lar National Park, Iran
Brown trout, Salmo trutta fario, has a wide range of distribution in the north of Iran and in Karaj, Lighvanchai and Karun Rivers, but there is no report about its feeding behavior in some water resources including the Lar Natural Park. In order to study feeding behavior of this fish during spawning season, a survey was carried out in the rivers of Elarm, Aab-Sefid, Kamardasht and Delichayi in ...
متن کاملFunction of boundary rivers in hydropolitics cooperation:Danube river study

Especially, approximately half of the worldchr('39')s population lives within the basin of these rivers, and more than 90% are living in countries with these basins. This condition, by creating an undeniable relationship of interdependence, has made water a criti...
متن کاملStudies on the Chlorophylls and Photosynthesis of Thermal Algae from Yellowstone National Park, California, and Nevada
1. Myxophyceae normally growing at 65 degrees C. evolved oxygen upon irradiation and showed evidence of retaining the power to carry on the process of photosynthesis at 20 degrees C. This indicates that extra thermal energy is not essential for photosynthesis at least over a short period of time. 2. Chlorophyll a and b found in several species of Myxophyceae growing in waters ranging in tempera...
متن کاملDefining and Evaluating Exotic Species: Issues for Yellowstone Park Policy
—Exotics are species that are foreign to an ecological assemblage in the sense that they have not significantly adapted to resident biota or to local abiotic conditions, and resident species have not significantly adapted to them. Although they need not be human introduced nor damaging, when they are, a negative appraisal of such exotic species can be justified. Human introduction of exotics in...
متن کاملInvasive species impact: asymmetric interactions between invasive and endemic freshwater snails
The strength of biotic interactions between native and invasive species is a key component of invasive species impact, but often is not quantified explicitly. We measured biotic interaction strengths between an invasive and a native endemic snail species in 2 streams in the western United States. The invasive freshwater New Zealand mudsnail, Potamopyrgus antipodarum, was the dominant snail in a...
