The influence of forest regrowth, original canopy cover and tree size on saproxylic beetles associated with old oaks [PDF]

open access: yes, 2000
Abandoned management has caused many sites with free-standing, large oaks (Quercus robur) to become more shaded. This study shows how forest regrowth affects beetle species associated with old oaks in south-eastern Sweden. Beetles were trapped by pitfall
