    Author : Simon Selberg; [2019]
    Keywords : aspen; populus; tremula; saproxylic; beetle; fauna; depot; species; richness; abundance; diversity; cwd; course; woody; debris; forest; asp; populus; tremula; vedlevande; skalbagge; fauna; depå; art; mångfald; diversitet; död; ved; cwd; skog;

    Abstract : The biodiversity of saproxylic organisms and in the case of this study, saproxylic beetles, is dependent on the amount and quality of course woody debris (CWD) in the environment. Over the past decades the quantity of CWD in Swedish forests has increased, yet the quality has decreased, forests are managed and exploited, and old-growth forests are rarer. READ MORE

  3. 3. Fire effects in a landscape of fear : food availability and perceived predation risk as potential determinants of patch utilization by herbivore prey

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : David Kymmell; [2019]
    Keywords : landscape of fear; forest fire effects; herbivore prey; camera trapping;

    Abstract : Context: A major effect of climatic change is the global increase in forest fires, which potentially creates an increase in food availability for herbivorous species. Also vegetation density and the numbers of tree logs increase in burned sites, and this is thought to influence the perceived risk of herbivore prey species, which affects their anti‐predator behaviour and thereby the patch utilization.

  5. 5. The relative importance of beavers (Castor fiber) and browsers on the recruitment of broad-leaved trees in riparian areas

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Matilda Karlsson; [2019]
    Keywords : beaver; Castor fiber; ungulates; herbivory; broad-leaved; riparian; conservation management;

    Abstract : Managed forest landscapes in Sweden are dominated by boreal coniferous forest and are deficient in broad-leaved trees. Both beavers (Castor fiber) and ungulate browsers prefer broad-leaved trees to conifers, and the interaction between multiple herbivores may have a considerable impact on the recruitment of deciduous trees in riparian areas.
