Surveying an endangered saproxylic beetle, Osmoderma eremita, in Mediterranean woodlands: a comparison between different capture methods

What is it about?

A mark-recapture study of an endangered saproxylic beetle was performed in central Italy by applying four independent capture methods. Detection probability and population size estimates were drawn from each of these four methods. We found that, since in the southern part of its distribution range, a single population of this endangered beetle is widespread in the landscape, conservation efforts should focus not only on preserving few and isolated monumental hollow trees, but should be extended to large stands.
