  2. 1. Deposit-feeding in benthic macrofauna : Tracer studies from the Baltic Sea

    Author : Lars Byrén; Ragnar Elmgren; Lisa A. Levin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Deposit-feeding; Macrofauna; Baltic Sea; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Abstract : A low content of organic matter, which is largely refractory in nature, is characteristic of most sediments, meaning that aquatic deposit-feeders live on a very poor food source. The food is derived mainly from sedimenting phytodetritus, and in temperate waters like the Baltic Sea, from seasonal phytoplankton blooms. READ MORE

  4. 2. The importance of biodiversity for ecosystem processes in sediments : experimental examples from the Baltic Sea

    Author : Johan Näslund; Jonas Gunnarsson; Sara Sjöling; Nils Kautsky; Antoine Grémare; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biodiversity; Soft-bottom sediment; Ecosystem processes; Ecosystem function; Benthic-pelagic coupling; Baltic Sea; Trophic interactions; Pollutant biodegradation; Organic matter mineralization; Deposit feeder; Detritivore; Invasive species; Marine ecology; Marin ekologi; marin ekotoxikologi; Marine Ecotoxicology;

    Abstract : Aquatic sediments are, by surface, the largest habitat on Earth. A wide diversity of organisms inhabit these sediments and by their actions they have a large influence on and also mediate many ecosystem processes. READ MORE

  5. 3. Volcanic stratigraphy, chemical stratigraphy, and hydrothermal alteration of the Petiknäs South Volcanic-hosted massive sulfide deposit, Sweden

    Author : Denis Schlatter; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Abstract : The main exploration methods which have been used in the Skellefte district are prospecting for ore boulders in young glacial deposits and electrical geophysical methods. The discovery of new ores which likely are located at deep levels (>200 m), requires improved exploration methods, which in turn require a better understanding of the geology and alteration patterns of the known VMS deposits.

  6. 4. 3D structural framework and constraints on the timing of hydrothermal alteration and ore formation at the Falun Zn-Pb-Cu-(Au-Ag) sulphide deposit, Bergslagen, Sweden

    Author : Tobias Christoph Kampmann; Pietari Skyttä; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Malmgeologi; Ore Geology;

    Abstract : The Falun pyritic Zn-Pb-Cu-(Au-Ag) sulphide deposit, situated in the Palaeoproterozoic (1.9–1.8 Ga) Bergslagen lithotectonic unit in the south-western part of the Fennoscandian Shield, is one of the major base and minor precious metal sulphide deposits in Sweden. READ MORE
