1. 1. Betesmönster hos älg (Alces alces) vintertid i fjällnära skog : En studie av födoval i relation till trädslagssammansättning och habitat

   Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Författare :Ella Hambeson; [2023]
   Nyckelord :Food choice; Alces alces; forested mountainous terrain; winter diet; selection; Betesval; Alces alces; fjällnära skog; vinterföda; selektion;

   Sammanfattning : Browsing patterns in large herbivorous mammals are complex and decisions regarding food items occur at different levels depending on internal or external factors such as energy requirements and available food sources. A broader understanding of the behavior of animals living in habitats of economic interests for humans enables human exploitation with as little impact as possible on the animals' habitats. LÄS MER

3. 2. Spatial co-occurrence between wind power and boreal forestlands with lichen important for reindeer browsing : a landscape analysis

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

   Författare :Erik Lundmark; [2022]
   Nyckelord :lichen; qGIS; reindeer; reindeer husbandry; spatial analysis; wind power;

   Sammanfattning : To meet the increasing demand of renewable energy, Sweden aim to expand the onshore wind power production from 30 TWh today, to 80 TWh by 2040. Most wind power sites will be placed in Northern Sweden, which coincides with the reindeer husbandry area, where indigenous Sami have a legislated reindeer husbandry right. LÄS MER

4. 3. Predation as a driver of reproductive isolation : Differences in predation risk between whitefish (Coregonus lavaretus) spawning habitats

   Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Författare :Benjamin Lindberg; [2021]
   Nyckelord :Coregonus lavaretus; reproductive isolation; predation; spawning habitat; spawning time;

   Sammanfattning : The origin and maintenance of much of natural biodiversity can likely be explained by theecological speciation theory. Ecological speciation is defined as the process whenreproductive isolation arises through divergent selection caused by ecological factors, such asbiotic interactions and abiotic conditions. LÄS MER

5. 4. Habitat selection in moose and roe deer : a third order comparison

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

   Författare :Irene Hjort; [2019]
   Nyckelord :gps; camera trapping; habitat selection; order of selection; Alces alces; Capreolus capreolus; brownian bridge kernel method;

   Sammanfattning : Ungulates are important animals in Swedish culture and economy, yet they are considered to cause considerable damage on forests to the disadvantage for the forest industry. At the same time, the forest industry is one of the reasons for the increased carrying capacity of moose and roe deer. LÄS MER

7. 5. Have wolves (Canis lupus) finally scared moose (Alces alces) in Sweden?

   Master-uppsats, SLU/Dept. of Ecology

   Författare :Mark Jamieson; [2018]
   Nyckelord :landscapes of fear; predator-prey interactions; habitat selection; resource selection functions; ecology;

   Sammanfattning : Carnivores are coming back to Europe and the repercussions of their return on prey species is not fully understood. Research from North American studies suggests predators can indirectly affect how ungulates will select their habitat which can result in a change in vegetation growth as browsing pressure is relaxed in risky areas.
