  1. 1. Eutrophication effects on a coastal macrophyte community in the Bothnian Sea

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

    Author : Emilia Linder Wiktorsson; [2021]
    Keywords : eutrophication; macrophytes; opportunistic algae; Baltic Sea; Bothnian Sea;

    Abstract : Eutrophication is a major concern in the Baltic Sea and it is affecting macrophyte communities by promoting the growth of opportunistic algae and decreasing the cover of perennial macrophyte species via shading. It is however uncertain how common eutrophication and its symptoms are in the northern parts of the Baltic Sea, the Botnian Sea. READ MORE

  3. 2. Herbivores effect on coral reefs : relationships between sea urchins, coral health and algae cover

    University essay from SLU/Dept. of Ecology

    Author : Linnéa Fridén; [2019]
    Keywords : sea urchins; coral health; coral bleaching; algae cover; correlation; influence;

    Abstract : Coral reefs are vital to marine ecology. The population dynamic on coral reefs are complex and sensitive to natural and anthropogenic changes. Various factors can affect the population dynamic and inflict change. Coral bleaching is threatening coral reefs worldwide and is a hot topic in today’s climate challenges. READ MORE

  4. 3. Stratigraphy and dating of a lake sediment record from Lyngsjön, eastern Scania : human impact and aeolian sand deposition during the last millennium

    University essay from Lunds universitet/Geologiska institutionen

    Author : Marijana Stevic; [2019]
    Keywords : aeolian activity; human impact; geochemistry; lake sediments; pollen; Earth and Environmental Sciences;

    Abstract : A small lake in north-eastern Scania, southern Sweden, Lake Lyngsjön, reveals a long history of aeolian sand drift based on a 3 meter long sediment sequence covering the last approximately 1400 years. Human impact, primarily through intensified land use and decreased forest cover, has periodically led to increased aeolian sand drift both locally and regionally. READ MORE

  5. 4. Importance of Fucus vesiculosus (bladderwrack) for coastal fish communities in the Baltic Sea

    University essay from Stockholms universitet/Institutionen för ekologi, miljö och botanik

    Author : Emma Mattsson; [2019]
    Keywords : Baltic Sea; Fucus vesiculosus; fish communities; fish nurseries; climate change;

    Abstract : Within temperate coastal seascapes, macroalgae provide habitats for different organisms such as invertebrates and fish. In analogy to seagrass meadows, macroalgae beds are known for their importance as fish nurseries. READ MORE

  6. 5. Cell Size Variation in Fossil Coccolithophores (Haptophyta) : A Study of Pliocene Sediments from Northwestern Australia

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Nicole Eliassen; [2018]
    Keywords : Coccolithophore; cell; carbon cycle; Australia; palaeobiology; climate change.; Fästalger Haptophyta ; kokkolitoforider; Pliocen; cell; kolcykel; Australien; paleobiologi; klimatförändring;

    Abstract : This report examines the size variations of fossil carbonate-producing haptophyte microalgae, coccolithophores, using sediments deposited during the Pliocene. The sediments were collected by the International Ocean Discovery Program (IODP) in 2015, off the coast of NW Australia (Gallagher et al., 2017). READ MORE
