Rozšíření mrchožroutovitých brouků (Coleoptera: Silphidae) otevřené krajiny ve vybraných nížinných oblastech České republiky

Abstract: Beetles of the family Silphidae are an important but imperfectly understood part of Palaearctic ecosystems. Our team studied the ecology of open-landscape silphids around Louny, Kutná Hora, Zábřeh and Židlochovice in 2008 and 2009. We used 420 baited pitfall traps and, at 84 localities, we collected 71 234 specimens of 15 silphid species. Distribution data for all species are provided here. We found three endangered carrion beetle species listed on the Czech Red List of Invertebrates. Two are vulnerable thermophilic species of open landscapes, Nicrophorus antennatus (Reitter, 1884) (collected around Louny and Židlochovice) and Nicrophorus germanicus (Linnaeus, 1758) (Louny, Zábřeh and Židlochovice). The third is the near threatened species, Nicrophorus sepultor Charpentier, 1825 (collected around Louny, Kutná Hora, Zábřeh and Židlochovice), which also prefers open landscapes.
