  1. 1. Light, temperature and competition : understanding the causes for climate-driven regime shifts in arctic marine benthos

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Kim Scherrer; [2015]
    Nyckelord :macroalgae; light; invertebrate; coralline algae; Arctic; benthic; regime shift; climate change; marin ekologi; tång; kalkalg; Arktis; regimskifte; klimatförändring; ljus;

    Sammanfattning : In the Arctic, shallow sea-floor communities have been documented to shift abruptly from an invertebrate-dominated state to a state with high macroalgal abundance. Climate warming, resulting in increased water temperatures and decreased sea ice cover, could trigger such regime shifts in benthic ecosystems, but the underlying mechanisms are not clear. LÄS MER

  3. 2. Petrology and depositional history of the Campanian strata at Maltesholm, Scania, southern Sweden

    Magister-uppsats, Lunds universitet/Geologiska institutionen

    Författare :Olof Sandström; [1994]
    Nyckelord :Kristianstad basin; Maltesholm; Campanian; grainstone; facies; storm sediments; hummocky cross bedding; conglomerates; shallow marine environment; rudists; belemnites; Earth and Environmental Sciences;

    Sammanfattning : Campanian sediments of the Maltesholm quarry consist of mostly coarse grained, poorly consolidated, ruditic grainstones, almost free of micrite and lime mud, with interbedded clay horizons. The main constituents of the grainstones are coralline algae and quartz. LÄS MER
