1. Quantity and quality of oaks (Quercus) as suitable habitats for the longhorn beetle species Plagionotus detritus : An inventory study in Stockholm and Uppsala County, Sweden
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : The longhorn beetle Plagionotus detritus is associated with newly dead oak wood and is declining throughout its distribution range. In Sweden, P.detritus has displayed one of the most dramatic reductions in distribution recorded for insect species and is near regional extinction. LÄS MER
2. Ekoparkernas inverkan på långhornskalbaggar (Cerambycidae) : artrikedom, abundans och artsamhällen i jämförelse med kommersiellt brukad skogsmark
Kandidat-uppsats, SLU/Dept. of Forest Ecology and ManagementSammanfattning : Several dead wood-dependent beetles need substrates which to great extent have been disfavored by intense forestry. Active and continuous restoration in Ecoparks may offer an option with intention to improve the habitation conditions. LÄS MER
3. Training dogs to indicate synthetic pheromones from Plagionotus detritus, Coleoptera, Cerambycidae to detect living beetles
Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)Sammanfattning : Using dogs to detect insects’ emitted volatiles is a non-invasive procedure, and a trained detection dog is potentially a fast and accurate method to search for saproxylic insects. The longhorn beetle Plagionotus detritus is categorized as Endangered in the Swedish Red List of Threatened Species. LÄS MER
4. Longhorn beetles in lesser spotted woodpecker habitat : a pheromone-based inventory of longhorn beetles in southern Sweden
Master-uppsats, SLU/Dept. of Plant Protection BiologySammanfattning : The understanding of species’ ecology and their trophic interactions, are crucial in the work of conservation. A population decline in a predatory species may be a result of a decline in their food source, a trophic level down. LÄS MER
5. Feromonbaserad inventering av eklevande långhorningsarter i fem habitattyper i sydöstra Sverige
Kandidat-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)Sammanfattning : Det intensifierade skogsbruket under de senaste 70 åren tillsammans med det ökade uttaget av avverkningsrester s.k. GROT (grenar och toppar) för biobränsleproduktion har lett till att ett flertal av Sveriges vedlevande insektsarter idag hotas av bristen på död ved. LÄS MER
