  1. 6. Do OTC warming effects on ecosystem processes depend on moss species identity, precipitation, and moss removal?

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Alexina Brännlund; [2023]
    Keywords : Experimental warming; Subarctic tundra mosses; Productivity; Ecosystem respiration; Decomposition;

    Abstract : Long-term warming experiments in arctic tundra have resulted in reduced moss cover and increased vascular plant cover. As mosses have a major impact on microclimatic conditions, changes in community composition can potentially alter direct and indirect drivers of productivity and decomposition, which are low in arctic ecosystems.

  3. 7. Mercury accumulation in lake sediments on different time scales – the influence of algal primary production

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Anne Rebotzke; [2023]
    Keywords : mercury; lake sediment; primary productivity; algal scavenging; biogenic silica; diatom proxy; chlorophyll-a; organic matter;

    Abstract : The aim of this work is to test the proposed approach of algal scavenging as a driver of sediment mercury (Hg) on different time scales and to gain a better understanding of the mechanisms of Hg accumulation in lake sediments. A 3000-year sediment record from Nylandssjön in northern Sweden was analysed for this purpose, as well as a 20-year sediment record from the seasonal sediment traps of this lake. READ MORE

  4. 8. Claws and Effect : how Small Carnivore Richness Responds to Habitat Diversity and Ecological Productivity
