    Sammanfattning : Sveriges energibehov 2020 var 508 TWh och av det är kärnkraft, biobränsle, olja och vattenkraft de viktigaste energislagen. På grund av att biogasproduktion har ett netto noll utsläpp har regeringen har valt att investera 40% av klimatklivets budget till dessa projekt. LÄS MER

  3. 2. Behavioural Responses of Ungulates to Sound Systems : can simulated risk influence behaviour?

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Nyckelord :ungulates; landscape of fear; behavioural response; predation risk; playback experiment; ABR; management strategies;

    Sammanfattning : Increasing ungulate densities all over Europe are intensifying the ongoing human-wildlife conflict, embodied by mainly economical losses through damages in forestry and agriculture. Given the current circumstances, farmers and forest owners prefer a decrease in ungulate numbers through direct population control, whereas other stakeholders, such as hunters, wildlife watchers or photographers, prefer higher wildlife numbers.
