Abstract
Diversity and conservation of saproxylic beetles in 42 European tree species: an experimental approach using early successional stages of branches
Highlights
Human impacts have modified forest ecosystems worldwide (Newbold et al, 2015)
To improve conservation practices for saproxylic beetles and especially red-listed species, we suggest a stronger incorporation of tree species diversity and sun exposure of into forest management strategies, including the enrichment of deadwood from native and with a specific focus on locally rare or silviculturally less important tree species
Even if the tree species was of less importance compared to sun exposure, it had a significant impact on communities of saproxylic beetles
Summary
Human impacts have modified forest ecosystems worldwide (Newbold et al, 2015). Intensive logging, altered disturbance regimes, and changes in forest structure have resulted in massive declines of ecological key elements, in EuropeEditor: Raphael Didham; Associate Editor: Mats Jonsell (Lindenmayer et al, 2008; Lindenmayer et al, 2012; Thorn et al, 2020). Human impacts have modified forest ecosystems worldwide (Newbold et al, 2015). Intensive logging, altered disturbance regimes, and changes in forest structure have resulted in massive declines of ecological key elements, in Europe. Dead and moribund trees have been extracted, as they were considered to be a waste of resources and to serve as a hatchery of forest pathogens (Cotta, 1865; Grove, 2002). Forest management practices have decreased the diversity of native tree species, for instance, by the establishment of coniferous tree plantations (Schelhaas et al, 2003) and the parallel introduction of various non-native tree species (Richardson & Rejmánek, 2011; Savill, 2015).
