  1. 11. Dietary preferences of Golden eagles (Aquila chrysaetos) in Sweden : a camera trap approach

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

    Author : Tomas Melin; [2020]
    Keywords : Aquilla chrysaetos; breeding; camera trap; Golden eagle; nestling; prey; Sweden;

    Abstract : Food availability and suitable habitat are necessary for reproductive success of raptors. Monitoring these variables may therefore provide important insights on fitness and population dynamics of species such as the golden eagle (Aquila chrysaetos), which are often very difficult to monitor.

  3. 12. Land cover changes in Southern Sweden from the mid-Holocene to present day: insights for ecosystem service assessments

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Robert O'Dwyer; [2019]
    Keywords : Geography; Geographical Information Systems; GIS; Physical Geography; Götaland; Landscape Reconstruction Algorithm; Fossil Pollen; Ecosystem Services; Earth and Environmental Sciences;

    Abstract : Climate change and human impact play a huge role in the sustainability and development of ecosystems and the services they offer to societies over temporal and spatial scales. Fossil pollen-based estimates provide unique information on past land cover change, but to date there are not many methods able to create spatially continuous maps and have a fine scale of land cover changes inferred from pollen information.

  4. 13. The effect of natural disturbances on the carbon balance of boreal forests

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Amelie Lindgren; [2011]
    Keywords : geography; physical geography; natural disturbance; carbon balance; boreal forest; geografi; naturgeografi; naturliga störningar; kolbalans; boreal skog; Earth and Environmental Sciences;

    Abstract : Natural disturbances such as fires, insect outbreaks and windthrows are able to influence the balance between the ecosystem gain and loss of carbon in the boreal forest. This effect of natural disturbances on the ecosystem carbon balance has been proposed as one of the reasons why the CO2 concentration in the atmosphere varies between years. READ MORE

  5. 14. 250 years of disturbance dynamics in a pristine old-growth Picea abies forest in Arkhangelsk region, north-western Russia : a dendrochronological reconstruction

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Tatiana Khakimulina; [2011]
    Keywords : Forest history; disturbance dynamics; canopy gap; old-growth forest;

    Abstract : To describe the historical patterns of natural disturbance regimes in European borealforests we conducted a dendroecological study in a primeval old-growth sprucedominated stands and reconstructed the long-term dynamics of canopy disturbances.We treated the radial growth releases of individual sub-canopy trees as the majorindicator of sudden openings in the forest canopy.

  6. 15. Mortality dynamics in an old-growth stand of beech (Fagus sylvatica) in Southern Sweden

    University essay from SLU/Southern Swedish Forest Research Centre

    Author : Mauricio Ivan Fuentes Perivancich; [2010]
    Keywords : beech; Southern Sweden; mortality dynamics;

    Abstract : Mortality patterns were assessed in an old growth beech stand in southern Sweden. Aprevious inventory of 1200 trees in 1996 was used as a base for an inventory in 2006.Mann-Whitney U test was used to compare statistical distribution between living anddead trees of those inventoried in 2006.
