  2. 1. The Big Bad EU? Species Protection and European Federalism : A Case Study of Wolf Conservation and Contestation in Sweden

    Author : Yaffa Epstein; Jan Darpö; An Cliquet; Uppsala universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Habitats Directive; species protection; subsidiarity; Endangered Species Act;

    Abstract : This dissertation examines how eco-knowledge intersects with the changes to EU legal cultures and practices known as eurolegalism. This conjunction has created a mechanism for the extension of EU law in the Member States even in the face of a weakened EU. READ MORE

  4. 2. Disentangling Lecania

    Author : Rikke Reese Næsborg; Leif Tibell; Stefan Ekman; Bengt Oxelman; Christian Printzen; Uppsala universitet; []
    Keywords : Biology; Crustose lichens; Phylogeny; Taxonomy; Morphology; New species; Phylogenetic diversity; Rare species; ITS; mt-SSU; RPB2; IGS; Biologi; Lecania; Ramalinaceae;

    Abstract : This thesis focuses on phylogenetic, taxonomic, ecological, and conservation aspects of the crustose lichen genus Lecania (Ramalinaceae, lichenized Ascomycota). Lecania has previously been defined on basis of relatively few morphological characters, and the genus had never been treated in molecular phylogenies. READ MORE

  5. 3. Food Webs, Models and Species Extinctions in a Stochastic Environment

    Author : Patrik Karlsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ekologi; Ecology; functional redundancy; trophospecies; species aggregation; environmental stochasticity; interaction strength; spectral colour; food web structure; food webs; extinction risk;

    Abstract : In light of the current global mass extinction of species, ecologists are facing great challenges. In order to reverse the path towards additional extinctions early warning systems to guide management actions need to be developed. READ MORE
