  2. 11. Evolving ecological communities in changing environments

    Author : Jacob Johansson; Evolutionär ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; adaptive dynamics; competition; community evolution; ecological communities; environmental change; evolutionary branching;

    Abstract : This thesis consists of theoretical studies of the evolutionary consequences of environmental change in ecological communities. Paper I and II are concerned with the origin of diversity, i.e. how a single lineage can split into two, under the influence of selection induced by competitive interactions (evolutionary branching).

  4. 12. Ecological niche dynamic, lessons from plankton

    Author : Baptiste Serandour; Monika Winder; Thorsten Blenckner; Eric Goberville; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plankton; Metabarcoding; Spatial distribution modeling; Ecological niche; Climate Change; marinbiologi; Marine Biology;

    Abstract : Abiotic conditions shape biological communities around the globe. Through spatial and temporal heterogeneity, environments impact plankton physiology, phenology and distribution. READ MORE

  5. 13. Making complex commons work : identifying critical social-ecological factors and mechanisms for sustainable ecosystem management

    Author : Caroline Schill; Therese Lindahl; Björn Vollan; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Agent-based modelling; Behavioural experiments; Collective action; Common-pool resources; Cooperation; Ecological complexity; Knowledge sharing; Regime shifts; Social-ecological systems; Sustainable management; Thresholds; Uncertainty; Sustainability Science; vetenskap om hållbar utveckling;

    Abstract : Collective action holds the key to many sustainability challenges, from local to global scales. Whether it is to manage community-based fisheries or take action against climate change or biodiversity loss – the question on how to overcome the conflict between individual and collective interests (i.e. READ MORE

  6. 14. Extinctions in Ecological Communities : direct and indirect effects of perturbation on biodiversity

    Author : Alva Curtsdotter; Bo Ebenman; Peter Münger; Elisa Thébault; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In the dawning of what may become Earth’s 6th mass extinction the topic of this thesis, understanding extinction processes and what determines the magnitude of species loss, has become only too relevant. The number of known extinctions (~850) during the last centuries translates to extinction rates elevated above the background rate, matching those of previous mass extinction events. READ MORE

  7. 15. Contested Landscapes : social-ecological interactions between forestry and reindeer husbandry

    Author : Tim Horstkotte; Jon Moen; Camilla Sandström; Micheline Manseau; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Reindeer husbandry; forestry; adaptive capacity; arboreal lichens; snow; winter pasture; natural resource management; multiple use; land-use conflict; habitat fragmentation;

    Abstract : Throughout northern Fennoscandia, reindeer husbandry is a central part in the cultural heritage of the Sámi people. In its history, Sámi culture and reindeer husbandry have undergone significant adaptations to environmental, social and political challenges. READ MORE
