  1. 1. Påverkar utfodring av unga vajor deras vikt, kondition och dräktighet?

    Kandidat-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Therese Nylén; [2022]
    Nyckelord :renar; vinterutfodring; vikt; kondition; dräktighet; reindeer;

    Sammanfattning : Vinterutfodring av renar (Rangifer tarandus tarandus) har blivit allt vanligare. Ökad nederbörd, växlande temperaturer och konkurrerande markanvändning av betesmarker, tex ökat skogsbruk och gruvor, har under de senaste decennierna resulterat i att det blir svårare för renen att finna bra vinterbete.

  3. 2. Den shifting behaviour of female wolverines (Gulo gulo) in Northern Sweden

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Rick Heeres; [2020]
    Nyckelord :wolverine; Gulo gulo; den; denning; denning behaviour; den shifts; habitat; environmental conditions; female experience; resource availability; survival analysis; reproduction; snow; climate;

    Sammanfattning : Many species of mammals make use of “den sites” for multiple purposes. Wolverine (Gulo gulo) females give birth to and rear their cubs in den sites during the denning season (February to June, hereafter denning season). LÄS MER

  4. 3. Effects of semi-domesticated reindeer’s maternal condition on calf survival

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Diego Stingo; [2018]
    Nyckelord :rangifer; calf; survival; weight; proportional odds; logistic regression;

    Sammanfattning : Semi-domesticated reindeer (Rangifer tarandus) husbandry in Sweden depends largely on sustainable management and productivity of the herd. Herd productivity is determined by the survival of the herd’s offspring from each year, which is affected by factors such as weather conditions, forage abundancy and predation. LÄS MER

  5. 4. Kan minskat lavbete och ett ändrat klimat ha nega-tiva konsekvenser för kalvningsresultat hos renar?

    Kandidat-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Emma Wärnsberg; [2018]
    Nyckelord :ren; caribou; Rangifer tarandus; dräktighet; kalvningsfrekvens; lav; vinterbete;

    Sammanfattning : Vinterdieten hos många renpopulationer består till största delen av lav. Främst på grund av det moderna skogsbruket har skogar inom renskötselområdet klassificerade som lavrika minskat med 71 % under de senaste 60 åren. LÄS MER

  7. 5. Maternal body condition : effect on time of calving, offspring survival and body weight in reindeer

    Master-uppsats, SLU/Dept. of Animal Nutrition and Management

    Författare :Caroline Korpinen; [2017]
    Nyckelord :reindeer; calf; mortality; weight; condition; nutrition; survival; predators;

    Sammanfattning : The reindeer husbandry faces many challenges and one of the most crucial is the high calf mortality. As some reindeer herding districts have their calving grounds based in the forest, they are at high risk of losing a large number of the calves each season to brown bear predation as the bears also rely heavily on the forest as their natural habitat.
