The usefulness of selected species and cultivars of willows for the enrichment of the feeding base of deer family in the Notecka Forest

A number of willow varieties and cultivars may be used as the components of the feeding base for deer family. It should be clarified which willow varieties and cultivars are especially preferred as their feed and are not too demanding with regard to their site and maintain their vitality for a long time withstanding eating deer. The Notecka Forest is a large forest complex, where conifer sites are in dominant. However, it is possible to find fragments of forest with the better water conditions, where the introduction of willows may be very advantageous

Pseudochrysis Semenov, 1891 is the valid genus name for a group of cuckoo wasps frequently referred to as Pseudospinolia Linsenmaier, 1951 (Hymenoptera, Chrysididae)

The cuckoo wasp genus Pseudochrysis Semenov, 1891 is currently treated by several authors as a junior subjective synonym of Euchroeus Latreille, 1809, due to a type species designation by O. W. Richards in 1935. In the original description of the genus Pseudochrysis, Semenov (1891) distinguished two subordinated taxa within the genus Pseudochrysis: the subgenus Pseudochrysis and the subgenus Spintharis (sensu Dahlbom 1854). Semenov included three species in the subgenus Spintharis, but failed to mention any species included in the nominal subgenus. He was the first author, however, who listed in a subsequent publication (Semenov 1892) eleven species to be included in the nominal subgenus. According to the International Code of Zoological Nomenclature (ICZN 1999, Art. 67.2.2), these eleven species are deemed to have been listed in the original description. One of these, Chrysura humboldti Dahlbom, 1845, was explicitly designated by Semenov (1892) as type species of Pseudochrysis. We therefore consider the designation of Pseudochrysis (Spintharis) virgo Semenov, 1891 as type species of Pseudochrysis by Richards (1935) as invalid. The currently widely used genus name Pseudospinolia Linsenmaier, 1951 (type species Chrysis uniformis Dahlbom, 1854) is consequently to be regarded as a junior subjective synonym of Pseudochrysis, given the current circumscription of the genus Pseudospinolia (including both Pseudospinolia humboldti and Pseudospinolia uniformis)
