Neozoen sind ein weit verbreitetes Phänomen. Einige Arten verursachen ökologische und wirtschaftliche Probleme und werden als eine der größten Umweltrisiken weltweit betrachtet. Zur Verwendung bei einer Initiative zum Monitoring von gebietsfremden Tierarten auf dem Biodiversitäts-Datenportal Observation.org haben wir eine Liste von Arten zusammenge...

The ability to locate and colonise ephemeral deadwood resources is crucial to saproxylic beetle assemblages. Saproxylic beetles locate suitable substrates mainly through visual cues and via olfactory cues emitted by deadwood, other insects and fungi. For the conservation of saproxylic beetles, it is essential to understand which abiotic and biotic...

Entomological survey of the Boubín old-growth forest was conducted in the Šumava National Park in 2020. In total 364 individuals belonging to 11 species of ground beetles (Carabidae) were collected using pitfall traps with vinegar. Saproxylic beetles were captured using flight interception traps with salt solution. A total of 90 species belonging t...

We observed a preference of saproxylic beetles towards shaded areas with different species composition between shaded and sun-exposed areas.

Gnathotrichus materiarius Fitch, 1858 is an invasive bark beetle that colonizes conifers and has spread widely in Europe. The beetle was introduced from North America to Western Europe, where it was first detected in France in 1933. In countries of Western and Northern Europe, the first detections were found at ports or airports, which probably ser...

Forest set‐aside is a commonly employed conservation strategy, but large‐scale disturbances regularly evoke discussions on its utility for biodiversity conservation in former production forests. In this study, we reconstructed the return of a primeval forest specialist, the beetle Peltis grossa (Linnaeus, 1758) of the family Trogossitidae, to two n...

Lowland oak forests host high biodiversity throughout Europe, and to maintain their high biodiversity potential we need to understand how current silviculture practices influence these ecosystems. The most common harvest approach in oak woodlands remains clear-cutting followed by site preparation for reforestation. The site preparation can vary in...

Most European temperate woodlands are managed as high forests by clear-cutting or selective cutting. Such forests are shady environments, providing limited opportunities for light-demanding woodland associated organisms. Coppicing has been identified as a suitable tool for biodiversity conservation, because it leads to a spatially and temporally dy...

Entomological survey of the Stožec-Medvědice site was conducted in the Šumava National Park in 2018. A total of 27 species of ground beetles (Carabidae) were collected using pitfall traps with vinegar. Important is finding of Carabus irregularis and Pterostichus selmanni roubali which are considered to be relict species of old-growth forests. Sapro...

After about hundred years of absence of the endangered beetle Peltis grossa in the area of the Šumava National Park, the species was found at 26 sites in years 2018-2020. Direct search methods such as reporting adults and exit holes, peeling the bark of snags and checking bark beetle pheromone traps were used to find the species. P. grossa inhabite...

Invasive organisms represent great threats to ecosystems and great challenges to forest management. In Europe, the black timber bark beetle (Xylosandrus germanus) is an invasive secondary pest that mostly attacks the logs of felled trees. We showed the invasion history for Europe and using many local surveys, we summarize the current distribution a...

As most European forests are commercially managed for wood production, excluding the disintegration phase of the forest development cycle, a serious decline of numerous species has been observed. The intensity of forest management is critical for biodiversity conservation, especially in regard to saproxylic organisms, as it reduces the abundance of...

The presence of the endangered beetle Phloeostichus denticollis was confirmed at two sites (Liščí Hřbety near Kubova Huť and Zátoňská Hora Nature Reserve) in the Bohemian Forest (Šumava in Czech, Böhmer-wald in German), Czechia. In total four individuals were captured by peeling the bark of sycamore maples. These are the first published records of...

We present new records of Dryocoetes himalayensis Strohmeyer, 1908 from Central Europe. This alien species of bark beetle, native in Himalayan region, has been recorded in one locality in Slovakia (Brestovany, Trna-va Region), two localities in Lower Austria (Marchegg and Drösing, Weinviertel Region) and four localities in the Podyjí National Park...

• Although most studies exploring the vertical distribution of arthropods in forests have been limited to discrete comparisons between understorey and canopy, few have sampled across multiple heights. • We studied vertical distribution of scolytine beetle flight activity in temperate lowland broadleaf and montane beech‐fir forests using flight inte...

We provide records of two endangered species of saproxylic insects, Aradus obtectus Vásárhelyi, 1988 (Hemiptera: Heteroptera: Aradidae) and Peltis grossa (Linnaeus, 1758) (Coleoptera: Trogossitidae), documenting for the first time their presence in the Bílé Karpaty Protected Landscape Area and Biosphere Reserve in the eastern Czech Republic (= the...

New distributional data on the rare and endangered saproxylic beetle, Peltis grossa (Linnaeus, 1758), and its Eastern vicariant Peltis gigantea (Reitter, 1882) are provided. Peltis grossa is recorded from 21 European countries, with first or first exact records provided for Asian Turkey, Kosovo, Macedonia and Montenegro. In contrast, the species is...

Objective: The finer scale patterns of arthropod vertical stratification in forests are rarely studied and poorly understood. Further, there are no studies investigating whether and how altitude affects arthropod vertical stratification in temperate forests. We therefore investigated the fine-scale vertical stratification of diversity and guild st...

List of sampled beetle species. Information on Family, number of specimen in the mountain and lowland forest, sparoxylic status (1: obligatory; 2: facultative; 3: potentially), trophic guild (m: mycetophagous; n: necrophagous; p: phytopagous; s: saprophagous; x: xylophagous; z: zoophagous), red list status (CR: critically endangered; EN: endangered...

Global warming and land-use change are expected to be additive threats to global diversity, to which insects contribute the highest proportion. Insects are strongly influenced by temperature but also require specific habitat resources, and thus interaction between the two factors is likely. We selected saproxylic beetles as a model group because th...

Little has been published on scolytine beetles of the Moravian-Silesian Beskids, a mountain range at the border of Czechia and Slovakia. Available information was either very general or focused on bark beetles of spruce forests. Several beech-fir forests have been preserved in the area, the most valuable ones protected in nature reserves. Due to a...

Níže uvedené nálezy byly učiněny v průběhu terénního cvičení Ústavu botaniky a zoologie PřF MU Brno ve dnech 11.–16. září 2010.
