  1. 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)

    Author : Klas Andersson; [2012]
    Keywords : Elater ferrugineus; Osmoderma eremita ; saproxylic; indicator ; Quercus sp. ; pheromones; conservation;

    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

  3. 22. Using sex pheromone and a multi-scale approach to predict the distribution of a rare saproxylic beetle

    University essay from Institutionen för fysik, kemi och biologi; Tekniska högskolan

    Author : Najihah Musa; [2012]
    Keywords : Conservation; Elater ferrugineus; habitat fragmentation; hollow deciduous trees; multi-scale approach; predicted distribution; sex pheromone;

    Abstract : The European red click beetle, Elater ferrugineus L., is associated with wood mould in old hollow deciduous tree. As a result of severe habitat fragmentation caused by human disturbance, it is threatened throughout its distribution range. READ MORE

  4. 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 biologi

    Author : Helena Johansson; [2011]
    Keywords : Conservation; coleoptera; beetles; saproxylic; broad-leaved trees; hollow; preferences;

    Abstract : 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

  5. 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 biologi

    Author : David Gilljam; [2009]
    Keywords : Metapopulation; Matrix; Fragmentation; Hollow oaks; Saproxylic; Conservation; Restoration;

    Abstract : 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.

  6. 25. Habitat preferences and reproductive success forthe threatened longhorn beetle Plagionotusdetritus

    University essay from SLU/Dept. of Ecology

    Author : Lina Sundkvist; [2009]
    Keywords : cerambycidae; longhorn beetle; reproductive success; oak; threatened;

    Abstract : Plagionotus detritus is a threatend longhorn beetle that only exists at one site in Sweden. It is saproxylic and depending on recently dead coarse oak wood for its larval development. READ MORE
