Upon recent rediscovery of the dolichopodid Orthoceratium lacustre (Diptera: Dolichopodidae) in Flanders (northern Belgium) three sites with potential habitat of the species in Flanders were visited in September 2016. The survey revealed the presence of a population of the species at each site. In order to explain its apparent absence in Flanders for nearly the past 40 years, information on the distribution,...
Aphid species Brachycaudus divaricatae Shaposhnikov, 1956, originally described from Turkmenistan and earlier known from the Middle East and Eastern Europe only, is a successful invader to Central Europe. Its principal winter host, Prunus cerasifera, was originally distributed in Central Asia, Near East, and South Eastern Europe. Now it is common in Eastern and Central Europe. Brachycaudus divaricatae...
Mass hibernacula of several tens of thousands of Pipistrellus pipistrellus associated with the swarming of bats during seasonal movements should serve as important sites of gene flow in this species. The massive occurrence of hibernating bats which is observed in few caves in the Carpathian Mountains encourages the idea that the genetic diversity at these sites will be greater comparing to known situation...
The main objective of this paper is to report the effect of shrub removal and mowing on the diversity and composition of ground-dwelling spider assemblages in Natura 2000 habitats of Mátra Mountains. We found significant effects of shrub removal and mowing on spider communities. Diversity decreased in the year following shrub removal but increased in the following years. Spider diversity in the final...
