Augyles crinitus (KIESENWETTER, 1850) (Coleoptera: Heteroceridae) was found in the Słonne Mountains: (UTM: EV89) Sanok-Olchowce vic., the Stream Olchowski. They are first record of this species from Poland.
Literatural records about true water beetles (sensu JÄCH 1998) of the Middle-Eastern Poland were compiled and critically analysed. 241 species have been recorded so far. Two further species were given basing on false determination (Helophorus micans, Limnebius stagnalis). Species recorded in particular faunistic regions were listed. The fauna of the analysed area was discussed according to its geographical diversity, habitat differentiation and the conservation of endangered habitats. The importance of this area for the protection of beetle species and assemblages was emphasized.
A new species of Austrelmis, A. uaik sp. nov., from Patagonia, is described from adults of both sexes. Mature larvae of this species are also described and illustrated in detail. Adults of A. uaik are compared with those of A. patagonica, the only other species known from Patagonia and with other described argentine Austrelmis species. Larvae of A. uaik are compared to other previously described larvae from Argentina. A key to the known species of Austrelmis known from Argentina is included.
Genetic variability of three sympatric crucian carp (Carassius carassius) populations from NW Poland was studied within a research project aimed at assessing the utility of those populations for stocking in inland waters. DNA samples were collected from 65 individuals. Restriction analysis was performed using 4 enzymes (HaeIII, HinfI, FspBI, TasI) of known restriction sites. The restriction profiles obtained were classi fied as belonging to a single haplotype (H-1). Selected DNA products were sequenced; the subsequent comparison made it possible to detect the presence of substitutions in the genome fragment analysed.
