The aim of our study is to describe and visualise the spread of two non-indigenous land snail species Cepaea nemoralis and Monacha cartusiana in the Czech Republic during more than 100 years period. Several factors play an important role in changes of the distribution of these species: ecological (climate change), ethological (passive dispersal potencial) and economic (increasing traffic as a vector of spreading). The spreading of M. cartusiana has a rapidly increasing trend. More than half sites in the Czech Republic were colonised by this species in 2000-2010. While the spread of C. nemoralis has been continuous during the last century, the rapid range extension was recorded in the last two decades. © 2012 Versita Warsaw and Springer-Verlag Wien.

Taxonomic notes are provided for several taxa of Vespinae. Vespula austriaca (Panzer, 1799) and Vespula infernalis (de Saussure, 1854) can be distinguished by the sculpturing on the frons in the queen. Vespula yunlongensis Dong and Wang, 2003, is a synonym of V. flaviceps (Smith, 1870), NEW SYNONYMY, while V. yulongensis Dong and Wang, 2002, is not a synonym of that species, but of V. rufa (Linnaeus, 1758), NEW SYNONYMY. The type of Vespa peruana de Saussure, 1867, has been found in Geneva, and the species is confirmed as a synonym of Dolichovespula norwegica (Fabricius, 1781). Vespula shinanoensis Takamizawa, 2005, is a nomen nudum. © New York Entomological Society.

Extensive research was undertaken from 2010 to 2013 that focused upon the invertebrate fauna occurring in greenhouses of the botanical and zoological gardens in Czech Republic and Slovakia. Occurrences of the alien earwig, Euborellia annulipes (Lucas, 1847), were found in three greenhouses in Czech Republic, and these findings are the first to document established populations in Central European greenhouses. The spectrum of foods consumed by E. annulipes was studied with a post-mortem analysis of the gastrointestinal tract contents. Based on the analyses, we can conclude that E. annulipes is an omnivorous species that, in greenhouse conditions, predominantly feeds on plant tissue. Despite the fact that E. annulipes also feeds on invertebrates, our study points to a small proportion of such food in its diet under free-choice conditions in greenhouses. According to the large portion of plant tissues in the species’ diet, it could potentially be a pest of cultivated plants, especially seedlings and young plants with soft tissue. © 2015, The Japanese Society of Applied Entomology and Zoology.

Based on our data and the published literature, Euodynerus dantici dantici (Rossi, 1790), Euodynerus disconotatus sulfuripes (Morawitz, 1885), Euodynerus fastidiosus (de Saussure, 1853), Rhynchium acromum Giordani Soika, 1952, Tachyancistrocerus komarowi komarowi (Morawitz, 1885), and Polistes nimpha irakensis (Gusenleitner, 1976) are new records for the fauna of vespid wasps of Iran. New localities were found for some species and subspecies previously known in Iran. © Kasparek Verlag, Heidelberg.

Norway Spruce is the economically most important tree species in Europe and has been cultivated in plantations on a large-scale at low elevations, far outside its natural range. In the Bohemian Forest, it naturally occurs in pure stands above 1150 m a.s.l. and as a mixed tree species from 650 to 1150 m a.s.l. An understanding of natural distributions and the diversity along temperature gradients at various elevations is important for conservation, pest management, and predictions of future species assemblages by global warming. Here we investigated the species richness of canopy arthropods in spruce trees along a gradient from 300 to 1300 m a.s.l. using flight-interception traps. We analyzed species richness by combining diversity partitioning with a moving window approach after standardizing sample size per plot. Total richness decreased linearly as the elevation increased, which reflected declining temperatures and a declining regional species pool. Phytophages (herbivores excluding xylophages) were the most influenced. Richness did not peak at the transition zones of the three ecological elevation zones, neither for all species, nor for any of the separate functional groups. However, the proportion of both beetle and true bug spruce specialists significantly increased with elevation and actually doubled in richness above 1000 m a.s.l., where spruce is naturally dominating. Our results indicate that even planted spruce trees at lower elevations maintain high levels of species richness. Further climate warming will promote overall species richness, especially of phytophages, at all elevations. However, spruce specialists may be seriously threatened by global warming. © 2010 Elsevier B.V. All rights reserved.
