1. 6. Beteende inför lek hos odlad respektive vild lax (Salmo salar L.) i Klarälven

   Kandidat-uppsats, Karlstads universitet/Fakulteten för samhälls- och livsvetenskaper

   Författare :Petra Wognum; [2011]
   Nyckelord :;

   Sammanfattning : In many regulated rivers, authorities have stocked hatchery salmon to compensate for loss of wild populations. However, hatchery fish have not always behaved as wild fish do, and stocking them has not always fully compensated for the loss of wild fish. LÄS MER

3. 7. Seasonal variations in distribution patterns and movements of bats in relation to habitat characteristics

   Master-uppsats, SLU/Swedish Biodiversity Centre

   Författare :Artiom Bondarenco; [2009]
   Nyckelord :key habitats; bats; Moldova; critical seasons; distribution; movements;

   Sammanfattning : Different types of land use, such as forestry and agriculture, change the distribution and composition of habitats in the landscape. In order to understand the consequences of that for different organisms, and to find methods for combining conservation with production of crops, timber and other products it is important to collect information on distribution pattern, habitat selection and movements of different organisms.

4. 8. Linking habitat characteristics and juvenile density to quantify Salmo salar & Salmo trutta smolt production in River Sävarån, Northern Sweden

   L3-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

   Författare :Johan Molin; [2008]
   Nyckelord :mapping; flow; substratum; electro-fishing; parr; radio-telemetry; spawning;

   Sammanfattning : Even though the European Union has set up goals for rivers that support wild salmon to reach a production that is 50% of the MAXIMUM natural potential, there is a general lack of knowledge about the production capacity of salmonids in Sweden. To estimate the production of salmon and sea trout in the Sävarån river, I combined habitat mapping with available electro-fishing data. LÄS MER

5. 9. Habitat selection by moose (Alces alces) in southwestern Sweden

   Magister-uppsats, Fakulteten för samhälls- och livsvetenskaper

   Författare :Anders Olovsson; [2007]
   Nyckelord :Alces alces; Euclidean distance-based analysis; global positioning system; habitat selection; moose; radio-telemetry; Sweden;

   Sammanfattning : The moose (Alces alces) is very important both economically and ecologically, therefore all knowledge of moose is vital for future management of the moose population. Little is known about moose habitat selection in Sweden. LÄS MER
