Host specificity, habitat and microhabitat preferences of xylophagous and saproxylic beetles

Collecting samples from flight intercept trap

We investigate general and local patterns of xylophagous and saproxylic beetle resource and habitat use. Sampling methods include mainly flight intercept traps and rearing from standardised baits made of wood of various tree species and exposed in various microhabitats of temperate and tropical woodlands.

Getting high with the „big shot“Diversity of saproxylic beetles in forest

Looking through a crystal ball: Past, present and future of beetles associated with old trees

Woodlands of lower Morava and Dyje rivers floodplain

Diversity of saproxylic beetles stands and falls with amount of available old, open-grown trees. Combining data on local habitat requirements of model taxa, with data on current number of suitable trees and trees potentially suitable in the future allows for identification of periods critical to old-tree associated fauna due to shortage of suitable habitats, and thus allows for taking adequate management measures. Further, using historical aerial photomaps, we are able to quantify extent of habitat loss during the last 100 years. The model species represent various guilds of old-tree associated biodiversity e.g. the Hermit beetle (Osmoderma barnabita) - a tree hollow specialist; the jewel beetle Eurythyrea quercus specialised on the dead-wood of very old oaks; and the Capricorn beetle (Cerambyx cerdo) specialised on living old oaks.

Population ecology and habitat requirements of endangered beetles

We investigate biology, habitat needs, population size, demography, and mobility of endangered beetles, including the globally threatened ground beetle Carabus hungaricus, the Alpine longhorn (Rosalia alpina), the Hermit beetle (Osmoderma barnabita), the Capricorn beetle (Cerambyx cerdo) and some other species.
