  1. 16. Predators and losses of farm animals : using historical swedish data to evaluate bounties

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Joakim Lundsten; Edvin Rapp; [2015]
    Keywords : bounty; Sweden; historical; predators; farm animals; damage; wolf; sheep;

    Abstract : Bounties have been a widely used method of wildlife management, especially for predators. Bounties were used by ancient Greeks and are still used frequently around the world. Despite this, there are few quantitative evaluations of the methods efficiency. READ MORE

  3. 17. Beyond genotype : Using SNPs for pedigree reconstruction-based population estimates and genetic characterization of two Swedish brown bear (Ursus arctos) populations

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Robert Spitzer; [2015]
    Keywords : molecular ecology; SNPs; pedigree reconstruction; rarefaction; population estimates;

    Abstract : Reliable population estimates are an important aspect of sustainable wildlife management but usually difficult to obtain for rare and elusive large carnivores. I tested a new method developed by Creel and Rosenblatt (2013) to estimate the population size of two Swedish brown bear (Ursus arctos) populations. READ MORE

  4. 18. Short window of opportunity for brown bear (Ursus arctos) predation on reindeer (Rangifer tarandus) calves

    University essay from SLU/Dept. of Ecology

    Author : Linnéa Eleonora Kjellberg; [2014]
    Keywords : Ursus arctos; Rangifer tarandus; predation; management; reindeer husbandry;

    Abstract : To improve and develop a management system for reindeer husbandry regarding minimizing depredation by brown bears, knowledge about current depredation patterns is required. Using data obtained from a predation study regarding brown bear predation on reindeer from 2010 to 2012 I aimed at investigating what solutions are available to minimize brown bear predation on reindeer calves.

  5. 19. SNP-based conservation genetics of the southern Swedish brown bear (Ursus arctos) population

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Joanna Fahlén; [2014]
    Keywords : molecular ecology; population genetics; eDNA; non-invasive;

    Abstract : Species with small population sizes needs to be managed in order to prevent extinction in the long-term. Genetic monitoring of wild populations over time is important since it enables for management strategies that takes the genetic status into consideration. READ MORE

  6. 20. Hur påverkar licensjakt björnstammens (Ursus arctos) tillväxt i Gävleborgs län?

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Fredrika Vretling; [2014]
    Keywords : brunbjörn; populationstillväxt; jakt; kvot ;

    Abstract : Licensjakt på brunbjörn har varit tillåten i Gävleborgs län i mer än ett decenium, samtidigt kan jakt påverka populationstillväxten stark eftersom björnar har en naturligt låg dödlighet. Detta gör det viktigt att förstå hur kön och ålder hos de fällda björnarna påverkar populationens framtida tillväxt. READ MORE
