Abstract

Apristus europaeus was recorded for the first time in Croatia. It was found in the dry river bed of the temporary Krčić River (Dalmatian Zagora region), situated beneath the Dinara Mountains. This record represents the southeasternmost distribution border of this species in Europe. Apristus europaeus was sampled with pitfall traps in July 2014. The substrate was composed of boulders, without mosses or algae. Microclimatic conditions were unfavourable for soil invertebrates, since the dry river beds were exposed to intense solar radiation and wind. Our findings show that A. europaeus could quickly recolonize new and unstable habitats, implying that it has a high dispersal capacity. However, this study raises the question of the A. europaeus habitat preference, for in previous studies, it was characterised as a stenotopic hygrophilous species inhabiting the banks of flowing waters.
