  1. 6. Effects of landscape patterns on small mammal abundance

    Författare :Frauke Ecke; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Landscape Ecology; Landskapsekologi;

    Sammanfattning : Several studies indicate a long-term decline in the numbers of voles in northern Fennoscandia. Altered land use and forest management practices have been proposed as possible causes of the decline. LÄS MER

  3. 7. Community Assembly and Spatial Ecology of Saproxylic Coleoptera

    Författare :Jonas Victorsson; Mats Björklund; Stefan Ås; Anne Magurran; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Terrestrial ecology; Terrestisk ekologi; Animal Ecology; zooekologi;

    Sammanfattning : Community assembly is the process deciding inclusion/exclusion of species in a developing community. Spatial ecology integrates spatial habitat factors with local biotic interactions within a given patch. I used standardized tree bolts (0.35-1 m long) to sample saproxylic (wood living) beetles in natural and managed forest types. LÄS MER

  4. 8. Ecosystem services - a tool in sustainable landscape management

    Författare :Magnus Tuvendal; Thomas Elmqvist; Rudolf de Groot; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ecosystem services; resilience; landscape; resource management; impact assessment; sustainability; sustainable; naturresurshushållning; Natural Resources Management;

    Sammanfattning : In this thesis I have worked with the ambition of approaching the question of how human-ecology interaction can be articulated in a way that is useful as a vector for societal transformation. The thesis addresses the difficult question of how the ecosystem service framework may help to address mismatches between social and ecological systems. LÄS MER

  5. 9. Ticks - ecology, new hazards, and relevance for public health

    Författare :Thérese Janzén; Monica Hammer; Patrik Dinnétz; Mona Petersson; Lars Korslund; Södertörns högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea region; eco-epidemiology; habitat; Ixodes persulcatus; Ixodes ricinus; landscape; risk; urbanization; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Sammanfattning : Ticks and tick-borne diseases are ranking second only to mosquitoes as vectors of pathogens responsible for diseases in both humans and domestic animals. In the countries around the Baltic Sea, two medically important tick species are increasing both in range and abundance, and the public health threat posed by tick-borne diseases in this area is steadily growing.

  7. 10. Fragmented landscapes : Assessment and communication of landscape connectivity in human-dominated landscapes

    Författare :Arvid Bergsten; Örjan Bodin; Bo Ebenman; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fragmentation; Connectivity; Network; Spatial; Landscape; Dispersal; Planning; Social-Ecological; Scale; IIC; STS; naturresurshushållning; Natural Resources Management;

    Sammanfattning : This licentiate thesis summarizes the first half of my PhD on the theme of management of fragmented landscapes. The thesis applies – and reflects on the use of – network analysis of connectivity in relation to landscape planning. LÄS MER
