| Description | We studied a population of the hermit beetle (Osmoderma barnabita) and co-occurring saproxylic beetles in hollow willows at a small, isolated site in Southern Moravia (Czechia) in 2006 and 2009. The relationship between the presence/absence of the hermit beetle and the number of other saproxylic species, as well as its co-occurrence with individual species were investigated. In 2006, the species richness of saproxylic beetles was significantly higher in the trees not occupied by the hermit beetle, whereas it was independent of its presence in 2009. With did not find any saproxylic beetle species positively associated with the presence of O. barnabita in the cavities. In 2006, two species were associated with cavities uninhabited by the hermit beetle. The aspects of the observed pattern and methodological bias are discussed. |
