Forestry is continually changing the habitats for many forest-dwelling species around the world. The grey-sided vole (Myodes rufocanus) has declined since the 1970s in forests of northern Sweden. Previous studies suggested that this might partly be caused by reduced focal forest patch size due to clear-cutting. Proximity and access to old pine forest and that microhabitats often contains stones...

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...

Examination of the original literature concerning species of Philometra (Philometridae, Dracunculoidea) parasitic in the abdominal cavity of European cyprinids revealed that P. abdominalis Nybelin, 1928 is a junior synonym of P. ovata (Zeder, 1803), a parasite of cyprinids of the genera Gobio, Phoxinus and Leuciscus. The valid name of the species parasitizing cyprinids of the genera Abramis, Ru...

Ongoing climate change is leading to browning of many lakes and coastal areas, which can impair fish body growth biomass production. However, whether how effects light limitation caused by on vary over early ontogeny unknown. In this study, we set up a mesocosm experiment test roach (Rutilus rutilus) responses depend size, if findings are robust densities. We also studied potential mechanism fo...

Abstract The habitat quality of the littoral zone is key importance for almost all lentic fish species. In anthropogenically created gravel pit lakes, often structurally homogenized with limited habitats. We supplemented deadwood brush piles in eight lakes and investigated diurnal seasonal use this other typical microhabitats by six dominant Shoreline habitats were sampled using point abundance...

The ability of targeted and nontargeted metabolomics to discover chronic ecotoxicological effects is largely unexplored. Fenitrothion, an organophosphate pesticide, is categorized as a "red list" pollutant, being particularly hazardous to aquatic life. It acts primarily as a cholinesterase inhibitor, but evidence suggests it can also act as an androgen receptor antagonist. Whole-organism fenitr...

A total of 81 roach (Rutilus rutilus) collected from 13 southern English river sites between 2007 and 2012, were analysed for organochlorine pesticides, PCBs, PBDEs and some metals. Unexpectedly high concentrations of the banned insecticide DDT and its degradation products DDE and DDD (∑DDTs) were found in the 10 fish from the river Lee (or Lea) which averaged 88 ± 70 (standard deviation) μg/kg...
