  1. 1. Drivers of flower size evolution in the selfing species Arabidopsis thaliana

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Clàudia Fernández Mestre; [2023]
    Nyckelord :Arabidopsis thaliana; petal size; fitness; selection; evolutionary drivers; GWAS;

    Sammanfattning : The influence of pollinators on the evolution of flower morphology has been extensively explored. Yet, the effect of other ecological factors, such as genetic drift, environmental filtering, and allometric constraints, gained less attention. In this study, we addressed the importance of those drivers in a predominantly selfing species. LÄS MER

  3. 2. Capacitated Multi Depot Green Vehicle Routing for Transporting End-of-Life electrical waste : A practical study on environmental and social sustainability within the field of CMDGVRP with heterogeneous fleets

    Uppsats för yrkesexamina på avancerad nivå, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Karl-Johan Djervbrant; Andreas Häggström; [2021]
    Nyckelord :VRP; GVRP; CMDGVRP; Routing; Optimization; Environmental; Sustainability; Environmental sustainability; Social sustainability; Waste collection; Heterogeneous fleet;

    Sammanfattning : A comprehensive study is presented of the Capacitated Multi DepotGreen Vehicle Routing Problem (CMDGVRP) applied to a heterogeneous fleet of electronic waste collecting vehicles with two objectives: to reduce the total fuel consumption of the vehicles (environmental sustainability) and to limit the continuous drive-time of the drivers (social sustainability). Research has been limited from this aspect, and in this study, the focus is on the practical application of pickup and delivery of electronic waste. LÄS MER

  4. 3. Retaining Organizational Agility : How to Stay Competitive Without Competing

    Master-uppsats, Uppsala universitet/Företagsekonomiska institutionen

    Författare :Jens Karlstedt; Sebastian Hellenborg; [2020]
    Nyckelord :Organizational Agility; Agile Management; Growth; People-Centric Approach; Dynamic Capabilities; Drivers; Enablers; Practices;

    Sammanfattning : While conventional approaches of managing organizations have been considered to be outdated, Organizational Agility has been acclaimed for its prowess to cope with today's increasingly volatile and dynamic environment. Yet the predominant focus has been directed towards how agility is achieved, while its retention as organizations grow has to a great extent been unexplored. LÄS MER

  5. 4. Adaptive Evolution of Resource Use, Phenotypic Diversity, and Productivity of Phytoplankton Communities

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Nils Hellekant; [2019]
    Nyckelord :Adaptive Dynamics; phenotype; phytoplankton; plankton; BEF; Biodiversity; diversity; Spatial modeling; Ecosystem function; Evolution; Diversity;

    Sammanfattning : There is growing concern that the worldwide loss in biodiversity will harm the stability of the ecosystems, and thereby, the carrying capacity and critical ecosystem services the biosphere provides. Phytoplankton (microalgae) in lakes and oceans are arguably the most important primary producers. LÄS MER
