21. Pheromone-based monitoring of Elater ferrugineus as an indicator for species-rich hollow oak stands
University essay from SLU/Plant Breeding and Biotechnology (until 121231)Abstract : The rare beetle Elater ferrugineus was sampled at 47 sites in the county of Östergötland, Sweden by means of pheromone-baited traps to assess its value as an indicator species for hollow oak stands rich in rare saproxylic beetle species. In addition Osmoderma eremita was sampled with the same method. READ MORE

23. Comparison of saproxylic beetle assemblages on four different broad-leaved tree species in south-eastern Sweden
University essay from Institutionen för fysik, kemi och biologiAbstract : Old hollow trees have declined in Europe and many saproxylic (wood-dwelling) beetles dependent on them are threatened. Several studies have been done on old hollow oaks and they have been shown to harbour a species-rich saproxylic beetle fauna. However, other broad-leaved trees might also be important to consider as supporting habitats. READ MORE

24. Metapopulation persistence of insects living in hollow oaks: effects of adding oaks in the surrounding landscape
University essay from Institutionen för fysik, kemi och biologiAbstract : The oak district of Östergötland is one of the largest oak forests left in Europe and it harbours many threatened species dependent on old hollow trees. In this study, the saproxylic beetle Osmoderma eremita living in hollow oaks was used as a model species and parameterised for a metapopulation model (the incidence function model) at the level of individual trees.
