The aim of this study was to analyze 16 trace elements (Al, As, B, Ba, Cd, Co, Cr, Cu, Fe, Li, Mn, Mo, Ni, Pb, Sr, and Zn) in different barbel (Barbus barbus) tissues and to detect the presence of genotoxic effects in erythrocytes with the alkaline comet assay. Barbel specimens were collected in the Danube river near Belgrade, Serbia, where the discharge of untreated communal and industrial was...

BACKGROUND Brominated flame retardants (BFRs)--polybrominated diphenyl ethers (PBDEs) and hexabromocyclododecane (HBCD)--belong to the group of relatively "new" environmental contaminants. The occurrence of these compounds in the Czech aquatic ecosystem was for the first time documented within the 3-year monitoring study initiated in 2001. In 2002-2003 HBCD and the major PBDE congeners (28, 47,...

The iguanid lizard Tropidurus peruvianus was studied along an ocean cliff and beach in northern Peru during winter. T. peruvianus inhabit arid coastal areas of Peru providing refugia such as cliffs, rock outcrops and driftwood. Lizards first appear at burrow entrances between 0730 and 0800 hrs, but may delay activity as much as four hours if conditions are unsuitable. The number of lizards acti...

the native fishes of iran are imp ortant, since the stock of population are declining and the species of some fishes are in danger , because of industrialization, pollution, dryness, purposeful or accidental introduction of exotic species. the inland water species of iran are import ant, since they have not been yet completely identified. in order to conduct taxonomic revision and survey of pop...

We describe a new species of goby, Varicus lacerta sp. n., which was collected from a mesophotic reef at Curacao, southern Caribbean. The new species is the tenth species of Varicus, all of which occur below traditional SCUBA depths in the wider Caribbean area. Its placement in the genus Varicus is supported by a molecular phylogenetic analysis of three nuclear genes and the mitochondrial gene ...

The Psammodromus hispanicus species group has been recently shown to include three lineages that differ in morphology (San-Jose et al. 2012), have largely parapatric range but exhibit little evidence of historical gene flow (Fitze et al. 2011), leading to the recognition of these three lineages as distinct species (Fitze et al. 2012). The eastern species can be unambiguously associated with the...
