2. 1. Habitat-Forming Seaweeds in a Changing Climate

   Author : Alexandra Kinnby; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ocean acidification; Warming; Freshening; Temperature; Salinity; pH; pCO2; Fucus vesiculosus; Phlorotannins; Grazing; Tissue resilience; Macroalgae;

   Abstract : Climate change is an umbrella term encompassing some of the largest and most potent selective pressures currently acting on ecosystems. It can have diverse effects on marine systems; the most powerful of which are changes to salinity through altered patterns of precipitation and evaporation, temperature through increased global temperature, and pH through the dissolution of CO2 into seawater where it ultimately reacts with water to form carbonate (CO32-) and hydrogen ions (2H+).

4. 2. From Sea to Society - Climate Change, Microbial Community Interactions and Assessing Climate Risk on Society

   Author : Gurpreet Kaur-Kahlon; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Phytoplankton; Bacteria; Climate change; Quorum sensing; Microbial blooms; Vulnerability factors; Arabian Sea; Southwest India;

   Abstract : Unicellular organisms, microalgae and bacteria, less than one millimeter in size make the world go round. Phytoplankton and cyanobacteria, for example, plays an inevitable role contributing 50-85% to the world’s oxygen via photosynthesis. READ MORE

5. 3. Baltic Sea phytoplankton in a changing environment

   Keywords : NATURVETENSKAP; NATURAL SCIENCES; phytoplankton ecology; cyanobacteria; dynamics; environmental factors; successional patterns; interactions; life strategies; non-ribosomal peptides; diversity; nodularin; N. spumigena; Akvatisk ekologi; Aquatic Ecology;

   Abstract : Future climate scenarios in the Baltic Sea project increasing sea surface temperature, as well as increasing precipitation and river runoff resulting in decreased salinity. These changes can severely impact the dynamics and function of brackish water communities, specifically phytoplankton. READ MORE

6. 4. Role of manganese redox cycling for trace metals in the Baltic Sea

   Author : Susanne Bauer; Per Hall; Luleå tekniska universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Applied Geology; Tillämpad geologi;

   Abstract : Redox zones are defined by steep gradients of changing concentrations and changing redox potential. They form a transition zone between oxic and anoxic/sulfidic conditions, where nitrate, manganese and iron reduction occurs. These redox zones can be situated in the sediment as well as in the water column. In the Baltic Sea both types are found. READ MORE
