“…The whole development lasts about two months (Silvestri 1919 In the Czech Republic, A. nebulosus occurs in coniferous, deciduous as well as in mixed forests, in lowland forests and even on forest-steppe habitats. We observed it very often on forest edges what was confirmed by Horváth et al (2002). A. nebulosus occurred almost exclusively on the forest edge but it was also present in the meadow close to the studied oak forests.…”

In the Czech Republic, A. nebulosus occurs in coniferous, deciduous as well as in mixed forests, in lowland forests and even on forest-steppe habitats. Larvae occur mainly on Picea sp., Pinus sp. and Abies sp.; adults occur on the same tree species and also on Larix sp., Quercus sp., Salix sp. and Fagus sp. Adults overwinter in the bark of several coniferous trees with thicker bark (mainly Pinus sylvestris L. and Larix decidua Mill.) where they are hidden in cracks. Woodpeckers attack such trees with masses ofA. nebulosus very intensively. In five localities with Malaise traps in the Nízký Jeseník Hills, the flight activity started at the beginning of May and ended in mid-June with the peak at the end of May and beginning of June in 2005. In 2006, the flight activity started later in mid-May and lasted to the beginning of July but was interrupted by cold and rainy weather. At higher altitudes were beetles sampled only in the first half of June in 2006. The size of males and females is very similar. In total, pronotum width of males varied between 0.85 mm and 2.40 mm, and females between 1.00 mm and 2.30 mm. There is no statistically significant difference between them. The equal sex ratio found in our material could confirm the fact that the flight activity of both sexes is the same.

“…These conditions possibly enable forest carabids to maintain stable populations in the ecotone. In addition, the great resemblance of the assemblages recorded in the forest interior and the forest edge is similar to that recorded in successional forest edges for other invertebrate taxa, such as spiders (Horváth et al, 2002) and various beetle families (Yu et al, 2006).…”

“…Several studies have shown that forest edges promote higher species richness, diversity and abundance in comparison to adjacent matrix habitats of various animal taxa, e.g. small mammals (Pardini, 2004), ungulates (Leopold, 1933, birds (Gates & Gysel, 1978) and spiders (Horváth et al, 2002). Forest edges, however, might have negative effects, particularly with respect to forest-inhabiting species, which avoid edges or have low abundance in these habitats (Lidicker, 1999).…”

Abstract. Boundaries between habitats are usually accompanied by transitions in the diversity and structural complexity of insect assemblages. Edge effects on carabid beetle assemblages across forest-meadow ecotones in Dinaric beech-fir forests were determined in the Gorski Kotar region of western Croatia. Carabid beetles were sampled using pitfall traps set along gradients extending 60 m from the forest edge into its interior and 60 m into the meadow. Embedded forest edges were greater than 100 years old and had a similar composition and structure of vegetation to that in the adjacent forest. A total of 20,526 individuals belonging to 66 carabid beetle species were recorded. Carabid assemblages in the ecotones were more similar to those in the forest interiors than those in the meadows. The classical edge effect hypothesis was not supported, since the ecotones were less diverse than the meadows, while the carabid assemblages of the forest interiors were the least diverse. Soil temperature, soil humidity and light intensity did not differ significantly between the ecotones and the forest interior. Therefore, embedded forest edges reduced the microclimate edge effect by providing stable microclimatic conditions for carabid assemblages similar to those in the forest interior. In addition, this enabled forest specialists and generalists to occur right up to the forest edge and maintain stable populations in the ecotone. On the other hand, ecotones acted as filters for certain forest generalist species and true barriers for most open-habitat species. This study confirmed that the structure and ages of the vegetation at edges may play a key role in determining the spatial pattern of carabid beetles across forest-meadow ecotones.

“…There were 10 randomly placed traps in all studied fragments. Each trap was 131 at least 50 m from the grassland edges, in order to avoid edge effects (Horváth et al 2002). 132 Traps consisted of 100 mm diameter plastic cups and contained about 200 ml 70 % eth-133 ylene glycol as a killing-preserving solution.…”
