The effects of 7- and 14-day exposure to water-dissolved Cu at sublethal concentrations 0.01 0.1 mg/L subsequent increase in water temperature a rate 8°C/h on intestinal proteolytic activity (PA) amylolytic (AA), as well brain acetylcholinesterase (AChE) water-soluble protein (WSP) content juvenile roach Rutilus rutilus have been vivo studied. Additionally, the values upper were determined by c...

Artificially cultivating Chroogomphus rutilus is too inefficient to be commercially feasible. Furthermore, isolating C. rutilus mycelia in the wild is difficult. Thus, it is important to determine the natural habitat of its fruiting body. This study focused on the ecology of the C. rutilus habitat to isolate and classify beneficial microorganisms that could affect its growth, which could be use...

Purpose. To assess the variability of histological parameters medial zone roach (Rutilus rutilus) liver. establish level effect transformed conditions existence on fish physiological status. determine prospect using monitoring data in ichthyological practice to morphofunctional state fish. Methodology. Primary materials were obtained different parts Southern Bug River, which differ their degree...

Quantifying the effects of human activity on the natural environment is dependent on credible estimates of reference conditions to define the state of the environment before the onset of adverse human impacts. In Europe, emission controls that aimed at restoring ecological status were based on hindcasts from process-based models or paleolimnological reconstructions. For instance, 1860 is used i...

Generalist species commonly have a fundamental role in ecosystems as they can integrate spatially distinct habitats and food-web compartments, as well as control the composition, abundance and behavior of organisms at different trophic levels. Generalist populations typically consist of specialized individuals, but the potential for and hence degree of individual niche variation can be largely ...

the purpose of the present study was to determine the acute toxicity (lc 50 ) of hgcl 2 and cuso 4 in caspian roach ( rutilus caspicus ) and cuso 4 in caspian kutum ( rutilus kutum ). the caspian roach lc 50 values for hgcl 2 at 24, 48, 72, and 96-hrs of exposure, were 0.64, 0.61, 0.42, and 0.28 mg l -1 , respectively, and for cuso 4 were 11.55, 5.08, 2.49, and 1.47 mg l -1 , respectively. the ...
