western parts of the chaharmahal and bakhtiyari province (ardal county) due to containing high mountains, deep valleys and small intermountain plains as well as the placement in the path of the nomads have long been of interest to humans. the nomadic communities of the mountainous regions of chaharmahal va bakhtiyari culturally interacted with the lowland areas of fars and khuzestan's plai...

From 1997 to 2004, we used radio telemetry to investigate movement and distribution patterns of 206 adult fluvial bull trout (mean, 449 mm FL) from watersheds representing a wide range of habitat conditions in northeastern Oregon and southwestern Washington, a region for which there was little previous information about this species. Migrations between spawning and wintering locations were long...

The sockey salmon entry to the Bolshaya River on Zavyalov Island in northern Okhotsk Sea was registered for first time July 26, 2021. Larger specimens were observed among pink going spawn this river, and one of them caught by a brown bear at distance 300 m from river mouth. It female sockeye Oncorhynchus nerka (Walbaum, 1792); data its size weight are presented.

Environmental DNA (eDNA) monitoring is a novel molecular technique to detect species in natural habitats. Many eDNA studies in aquatic systems have focused on lake or ponds, and/or on large vertebrate species, but applications to invertebrates in river systems are emerging. A challenge in applying eDNA monitoring in flowing waters is that a species' DNA can be transported downstream. Whether an...

Hydrologic regime plays a major role in structuring biotic diversity within river ecosystems by controlling key habitat conditions within the river channel and floodplain. Daily flow records from seven hydrological stations and the range of variability approach were utilized to investigate the variability and spatial pattern of the hydrologic alterations induced by the construction of the Three...

This paper introduces new insights into the hydrochemical functioning of lowland river systems using fieldbased spectrophotometric and electrode technologies. The streamwater concentrations of nitrogen species and phosphorus fractions were measured at hourly intervals on a continuous basis at two contrasting sites on tributaries of the River Thames – one draining a rural catchment, the River En...

The 1993 flood of the Missouri River led to the abandonment of agriculture on considerable land in the floodplain. This abandonment led to a restoration opportunity for the U.S. Federal Government, purchasing those lands being sold by farmers. Restoration of this floodplain is complicated, however, by an imperfect understanding of its past environmental and vegetative conditions. We examined en...
