  2. 2. Metapopulation ecology of Osmoderma eremita - dispersal, habitat quality and habitat history

    University dissertation from Jonas Hedin

    Author : Jonas Hedin; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; extinction debt; habitat history; habitat quality; pheromone; telemetry; capture-mark-recapture; metapopulation; dispersal; oak; Osmoderma eremita; beetle; Animal ecology; Djurekologi;

    Abstract : This thesis starts with a review of different biodiversity assessment methods in forests and the rest deals with the metapopulation ecology of Osmoderma eremita, a threatened beetle living in hollow trees. I concentrate on the effect of dispersal, habitat quality and habitat history for the presence, population size and future survival of this species. READ MORE

  3. 3. Habitat compensation in nature-like fishways Effects on benthos and fish

    University dissertation from Karlstad : Karlstads universitet

    Author : Stina Gustafsson; Olle Calles; Martin Österling; Jostein Skurdal; Paul Giller; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biocanal; biodiversity; brown trout; freshwater pearl mussel; functional feeding groups; habitat heterogeneity; large woody debris; macroinvertebrates; PIT-tag; salmonids; Biology; Biologi;

    Abstract : The construction of nature-like fishways has become an increasingly common measure to restore longitudinal connectivity in streams and rivers affected by hydroelectric development. These fishways also have the potential to function as habitat compensation measures when running waters have been degraded or lost. READ MORE

  5. 5. Small biotopes in agricultural landscapes: importance for vascular plants and effects of management

    University dissertation from Lund University, Faculty of Science

    Author : Therese Irminger Street; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Small biotopes; incidental habitat; vascular plants; woody vegetation; grassland species; resource provisioning; species richness; habitat specificity; non-crop habitat; landscape complexity; heterogeneity; local management; agri-environment scheme;

    Abstract : As a consequence of agricultural intensification, large areas of non-crop habitat have been lost and farmland biodiversity has declined. Previous studies have shown that the extent of non-crop habitat influences farmland biodiversity, but the relative importance of different habitat types is less well known and the contribution of small incidental habitats to landscape-scale species richness is not fully understood.
