  2. 1. The potential of wetlands for mitigation of eutrophication and brownification

    Author : Anna Borgström; Akvatisk ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Brownification; Constructed wetlands; Cyanobacteria; Eutrophication; Filamentous algae; Green algae; Macrophytes; Multifunctionality; Nitrogen; Phosphorus; Total organic carbon; Water color;

    Abstract : Increasing nutrient concentrations (eutrophication) and water color due to dissolved organic matter (brownification) pose continuous threats to freshwater ecosystems worldwide, threatening ecosystem services like drinking water supply. Changing the increasing trends of eutrophication and brownification on our aquatic ecosystems is challenging. READ MORE

  4. 2. Brownification of freshwaters - the role of dissolved organic matter and iron

    Author : Sara Ekström; Enhet akvatisk ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Brownification; freshwater; water color; dissolved organic matter DOM ; iron Fe ; decreasing acidification; climate change;

    Abstract : The term brownification refers to the trend of increasing water color, i.e. the water becoming browner, which has been observed throughout the northern hemisphere over the last decades. Brownification has both ecological and societal implications. READ MORE

  5. 3. Multiple stressors in rotifer communities: : Effects of predation, climate change, and brownification

    Author : Huan Zhang; Enhet akvatisk ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Climate change; community dynamic; brownification; heat wave; inducible defense; rotifer; plasticity; multiple stressors; Predation; prey;

    Abstract : Most organisms on Earth live in an environment where they are exposed to multiple pressures, including predation and climate change. In many aquatic ecosystems, organisms have to handle additional challenges such as brownification, co-occurring with climate warming. READ MORE

  6. 4. Plankton communities in a changing world - responses to temperature, brownification and lake restoration

    Author : Mattias Ekvall; Enhet akvatisk ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Climate change; temperature; warming; brownification; biomanipulation; zooplankton; cyanobacteria; microcystin; grazing; Daphnia;

    Abstract : The effects of increasing temperatures, in light of climate change, have been a well-studied topic during the past decades. However, aquatic ecosystems are also faced with additional challenges such as increasing water colour, known as “brownification”. READ MORE

  7. 5. Structuring factors for macroinvertebrate communities and the importance for ecosystem processing

    Author : Pia Hertonsson; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ephemeroptera; competition; Predation risk; brownification; invasive sp.; decomposition; grazing; growth; gastropoda; mortality; amphipoda; isopoda;

    Abstract : Aquatic macroinvertebrates play important roles in our ecosystems and are essential for the ecosystem processing. An improved knowledge of structuring factors, such as competition and predation, and the way in which they operates in the macroinvertebrate community is crucial for our understanding of not only the macroinvertebrates but also the ecosystem in general.
