We study various aspects of ecology, biology and diversity of insects associated with woodlands together with processes affecting their habitats and survival. Our research combines entomology, ecology, forestry and GIS methods in order to contribute to rational, evidence-based conservation of biodiversity. To facilitate for information flow between the academic and the "real" worlds we also collaborate with various NGOs, state organizations, land owners and media.

VetExT excursion to Sweeden and Norway
Between August 6 and 18, Pavel Šebek and Petr Kozel, together with colleagues from ČSOP Vlašim and Arboristicá akademie took part in a workshop to learn more about veteranisation and tree management in northern Europe. We visited several sites with solitary trees, grazed forests including protected areas and palace parks in Sweeden and Norway. For instance, we saw one of the oldest (900 years) oak and one of the largest (ca 720 cm in circumference) elm in Europe. In the end, we learned numerous insights into traditional tree and forest management focused mainly on sustaining biodiversity and public security.

The legal action against the Ministry of Agriculture
Biology Centre CAS has pressed charges against the Ministry of Agriculture of the Czech Republic. The reason was a long-standing argument about the forest management plan that should be applied in the forest owned by the Biology Centre in the South Moravian Region.

Interreg excursion to France
Between 7.-15. October 2019, several members of our team, together with colleagues from AOPK, ŠOPSR, ČSO and Krok Kyjov went for an excursion to learn more about coppicing and pollarding in western Europe. We visited foresters in Bad Windsheim (Germany) and discussed their experience with bigger-scale middle-forest management. In France, we stopped in Maison Botanique (Boursay) in exposition of pollarded trees and then moved to Marais-Poitevin to see large-scale traditional management of pollarded ashes along river channels. We continued to the borders with Spain to Sare where we visited pollarded oaks, beeches and traditionally grazed forests. Altogether, we got several new insights and tips for traditional forest managements.

Trip to Russia
In summer 2019 our team, together with the German colleagues from the team of Jörg Müller, visited the Orenburg Region in southwestern Russia. A majority of the biodiversity in this region is shared with the Czech Republic or Germany, but due to a very low intensification in the local forestry and agriculture, many species and habitats we consider rare are quite commonplace.

Sampling in Stará obora
In 2019 we installed 12 window traps in Stará obora near Hluboká nad Vltavou. This sampling is a part of a large veteran project investigating the effect of deadwood microhabitats and sunlight on saproxylic communities. We also searched for saproxylic beetles in the area in order to collect some samples for the isotopic analyses. The fieldwork was carried out by Petr Kozel, Pavel Šebek and Jan Kadlec.

Cerambyx cerdo | Author: Lukáš Čížek
New article released
Our latest research article has been published in European Journal of Entomology. The paper describes the differences in realized niche of a veteran tree specialist, Cerambyx cerdo, among three sites in South Moravia. Although it is generally found on large veteran trees, the beetle can exploit even trees with small diameters, when these are in open conditions and their health deteriorated.

Paper and Cover
Our new paper Phylogeography of the endangered saproxylic beetle Rosalia longicorn, Rosalia alpina (Coleoptera, Cerambycidae), corresponds with its main host, the European beech (Fagus sylvatica, Fagaceae) illustrates how the population genetic structure of the phytophage is shaped by its close relationship to main host.

Moreover, the picture of the Rosalia longicorn (Rosalia alpina) was selected for the cover image of the December 2018 Issue of Journal of Biogeography.

Guidelines for conservation
In September, Ministry of the Environment has certified the guidelines for conservation of open woodlands written by our team members. The document describes different management strategies that can be used in maintenance and restoration of open woodland habitats. It should serve as a general guideline for conservationists, stakeholders and managers of protected areas.
