  1. 1. Conservation of saproxylic beetles in a wooded pasture in northern Scania

    Master-uppsats, Lunds universitet/Examensarbeten i biologi

    Författare :Andreas Schmidt; [2018]
    Nyckelord :Biology and Life Sciences;

    Sammanfattning : The area of wooded pasture in Europe has decreased drastically over the last centuries due to abandoned management. Herrevadskloster is a newly formed nature reserve in northern Scania with an unusually long continuity of being an open, grazed woodland containing large old trees. LÄS MER

  3. 2. Medium-term population development and responses to habitat conditions of a beetle, Osmoderma eremita, inhabiting hollow trees

    Uppsats för yrkesexamina på avancerad nivå, SLU/Southern Swedish Forest Research Centre

    Författare :Olle Tranberg; [2016]
    Nyckelord :Osmoderma eremita; European hermit beetle; metapopulation; colonization and extinction; habitat; saproxylic species; tree hollows; Pedunculate oak; Quercus robur;

    Sammanfattning : Old oaks play an important role in the southern Swedish landscape by maintaining available habitats for many saproxylic species, several of which today are on the international Red List of threatened species. Old oaks can develop important habitats, such as hollows with wood mould, which is the habitat for the European hermit beetle (Osmoderma eremita). LÄS MER

  4. 3. Comparison between three landscape analysis tools to aid conservation efforts

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Elsa Nordén; [2016]
    Nyckelord :circuit theory; graph theory; connectivity; habitat fragmentation; GIS algorithms; Physical Geography and Ecosystems Analysis; Earth and Environmental Sciences;

    Sammanfattning : Habitatminskning är ett stort hot mot den biologiska mångfalden, som ofta orsakar sämre spridning mellan habitat. I och med att kunskapen om landskapssamband har växt, har GIS-verktyg för att rumsligt analysera landskapssamband för olika arter blivit allt vanligare. LÄS MER

  5. 4. Vems landskap ska förändras för att öka den biologiska mångfalden? : En studie av skillnaderna i odlingslandskapets konnektivitet med avseende på två skyddsvärda arter med olika preferenser

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Lisa Arnesén; [2014]
    Nyckelord :Betweenness centrality; component analysis; patch; component; ecology; landscape perspective; ekologi; nätverksanalys; konnektivitet; landskapsekologi; landskapsperspektiv; biologisk; mångfald; komponentanalys; läderbagge; bivråk;

    Sammanfattning : Organisms relevant for nature conservation dont follow administrative borders. Because of this there is a need for a landscape perspective within conservation and planning, and a need for the species of interest to have legal protection. LÄS MER

  7. 5. Pheromone-based monitoring of Elater ferrugineus as an indicator for species-rich hollow oak stands

    Master-uppsats, SLU/Plant Breeding and Biotechnology (until 121231)

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

    Sammanfattning : 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. LÄS MER
