In the course of forest management works in the Karkonosze National Park a total of 630 circular sample plots arranged in a 200 × 300 m graticule were established using the mathematical statistical method. Litter samples were collected from the centres of these plots in the autumn of 2002 and 2003 in order to determine the species composition of groups of rove beetles (Staphylinidae) and to prepare their zoocenological characteristics. A total of 136 beetles, belonging to 32 taxa, were found in samples. Identified groups were analysed using zoocenological indexes for montane and subalpine forests. It was found that the dominant species were Othius subuliformis Steph., Geostiba circellaris (Grav.), and Amischa analis (Grav.). In the groups of the montane forest 15 taxa were distinguished with a distinct domination of Othius subuliformis and Geostiba circellaris. Staphylinidae groups of the subalpine forest consist of 26 taxa and indicate a domination structure characteristic for undi...

Trends of changes in species richness and dominance in staphylinid communities depending on the age of pine plantations have been analyzed. The species richness of these communities is high in the plantations of age classes 1 and 2 (11 and 28 years, respectively) but decreases in the plantations of age class 3 (60 years). The highest and lowest indices of species diversity are observed in the plantations of age classes 2 and 3, respectively. Four groups of rove beetles have been distinguished by the criterion of their dominance in pine plantations of different ages.
Studies on rove beetles [Coleoptera: Staphylinidae] in Hungarian orchards ecosystems
Journal of fruit and ornamental plant research, 2006
Dominance and distributions of rove beetles in apple and pear orchards were studied in Hungary. Omalium caesum, Sphenoma abdominale, Drusilla canaliculata, Palporus nitidulus, Dexiogyia corticina, Mocyta orbata, Oligota pumilio and Purrolinus laeticeps were the species usually found with higher relative abundance in the orchard staphylinid communities. Although these species occurred in most of the orchards, their abundance varied considerably and their relative abundance in the total sample was under nine percent. Considering the different soil types, staphylinid species were more frequently found in sandy or sandy-loam soils than in clay, but the difference was not significant. The staphylinids were frequently found in the conventionally treated and also in the abandoned plantations. The soil types, herb cover of the orchards and the treatments played role in forming the staphylinid communities in the orchards.

In the present paper the authors offer new data to the knowledge of the beetle fauna from the Breite reserve. Altogether 40 species were identified during this study. The majority of species are common in Romania. Cerambyx cerdo Linnaeus, 1758, Morimus funereus Mulasant 1863 and the stag beetle Lucanus cervus (Linnaeus, 1758) are listed in the Annex II of the Habitats Directive. Faunistical analysis for the recorded data and management recommendations are given also.
The species richness and species composition of Coleoptera assemblages were investigated in deciduous tree canopies in Hungary. Apple and pear orchards were investigated in Nagykovácsi, Kecskemét and Sárospatak in 1990-94, and limes and maples in Keszthely in 1999-2002. This study presents in detail the findings on leaf beetles. Earlier investigations in Hungary revealed surprisingly high diversity of Coleoptera assemblages in the canopy of apple and pear orchards. Altogether 324 species, almost 3 per cent of Hungary's beetle fauna, were represented: 253 in apple and 188 in pear orchards. The majority of the species belonged to the Curculionidae, Chrysomelidae and Coccinelidae families. The proportion of leaf beetles ranged between 15 and 20 %. The commonest leaf-beetle species in the canopy of the commercial orchards investigated were Phyllotreta vittula, Phyllotreta atra, Phyllotreta nigripes, Oulema melanopus, and Aphthona euphorbiae. In the abandoned orchards, the commonest were Luperus xanthopoda, Smaragdina salicina and Orsodacne lineola. Examination of the fauna of parks, avenues and other planted urban plant stocks has only begun to occupy researchers in the last decade. Analysis of the full Arthropoda assemblages of these plant stocks has still not been undertaken. The proportion of leaf-beetle species in the material gathered on maples and limes in Keszthely ranged between 17.0 and 21.3 per cent. Apart form leaf beetles, the bulk of the specimen material collected consisted of species of the Coccinellidae, Staphylinidae and Curculionidae families. The commonest leaf-beetle specimens collected in the lime canopy were Aphthona euphorbiae, Chaetocnema tibialis, Longitarsus lycopi, Longitarsus pellucidus, Longitarsus pratensis and Longitarsus succineus. The commonest on maple were Aphthona euphorbiae, Chaetocnema concinna, Chaetocnema tibialis, Longitarsus lycopi, Longitarsus pellucidus, Longitarsus succineus, Phyllotreta cruciferae and Phyllotreta vittula. It was concluded that leaf beetles contribute a high proportion of the biodiversity of the deciduous tree canopy, sometimes occurring with high species richness and abundance. However, the reasons for this occurrence and their potential role are poorly understood.

Monitoring saproxylic beetle diversity, though challenging, can help identifying relevant conservation sites or key drivers of forest biodiversity, and assessing the impact of forestry practices on biodiversity. Unfortunately, monitoring species assemblages is costly, mainly due to the time spent on identification. Excluding families which are rich in specimens and species but are difficult to identify is a frequent procedure used in ecological entomology to reduce the identification cost. The Staphylinidae (rove beetle) family is both one of the most frequently excluded and one of the most species-rich saproxylic beetle families. Using a large-scale beetle and environmental dataset from 238 beech stands across Europe, we evaluated the effects of staphylinid exclusion on results in ecological forest studies. Simplified staphylinid-excluded assemblages were found to be relevant surrogates for whole assemblages. The species richness and composition of saproxylic beetle assemblages both with and without staphylinids responded congruently to landscape, climatic and stand gradients, even when the assemblages included a high proportion of staphylinid species. At both local and regional scales, the species richness as well as the species composition of staphylinid-included and staphylinid-excluded assemblages were highly positively correlated. Ranking of sites according to their biodiversity level, which either included or excluded Staphylinidae in species richness, also gave congruent results. From our results, species assemblages omitting staphylinids can be taken as efficient surrogates for complete assemblages in large scale biodiversity monitoring studies.

Identification of forest stands with priority for the conservation of biodiversity is of particular importance in landscapes with a long cultural and agricultural history, such as Central Europe. A group of species with a high indicator value for the naturalness of forest ecosystems are saproxylic insects. Some of these species, especially within the order Coleoptera, have been described as primeval forests relicts. Here, we compiled a list of 168 "primeval forest relict species" of saproxylic beetles based on expert knowledge. These species can serve as focal and umbrella species for forest conservation in Central Europe. They were selected because of their dependence on the continuous presence of primeval forest habitat features, such as over-mature trees, high amounts of dead wood, and dead wood diversity, as well as their absence in managed Central European forests. These primeval forest relict species showed a moderately strong clumping pattern within the phylogeny of beetles, as indicated by phylogenetic signal testing using the D-statistic. When we controlled for phylogenetic relatedness, an ordinal linear model revealed that large body size and preference for dead wood and trees of large diameter are the main characteristics of these species. This list of species can be used to identify forest stands of conservation value throughout Central Europe, to prioritize conservation and to raise public awareness for conservation issues related to primeval forests.
