This article presents the first record of the bark bug Aradus (Aradus) aterrimus Fieber, 1864 in the Czech Republic.

The locality hosts a considerable number of old, often hollow trees (Acer pseudoplatanus, Fagus sylvatica, Quercus petraea, Tilia cordata), with older shrubs of Corylus avellana and younger individuals of the aforementioned tree species in the undergrowth. A large amount of dead wood is present,...

The work aimed to evaluate the current state of the ichthyofauna in the Slovak section of the Vlára River, paying particular attention to the distribution and selected population characteristics of the Bulgarian golden loach (Sabanejewia bulgarica). As part of the ichthyological survey, a total of 17 fish species belonging to 10 families were recorded at four localities in the longitudinal profile of the river. The barbel and grayling zone’s characteristic rheophilic species dominated in terms of abundance (A. bipunctatus, G. obtusirostris, P. phoxinus, S. cephalus a B. barbus). The Bulgarian golden...
