  1. 1. Flagellates in the marine microbial food web the ecology of a mixotrophic nanoflagellate, Ochromonas sp

    University dissertation from Umeå : Umeå universitet

    Author : Agneta Andersson-Nordström; [1989]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Microbial food web; flagellates; Ochromonas sp.; mixotrophy; size- selective grazing; remineralisation; excretion of DFAA;

    Abstract : Nanoflagellates were found to be abundant in a coastal area of the northern Bothnian Sea. The maximum concentration of nanoflagellates, approximately 8000 cells ml-1, was observed in July, coinciding with a decrease in the abundance of cyanobacteria. READ MORE

  2. 2. Submicron Calcium Phosphate Spheres for Biomedical Applications Synthesis and Use

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Tao Qin; Uppsala universitet.; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; calcium phosphate; spheres; dentinal hypersensitivity; drug release; tooth bleaching;

    Abstract : Calcium phosphate spheres as biomaterials have been attracting attention in recent years. Calcium phosphate occurs naturally in bone, and a hollow structure could be advantageous for drug loading and release. READ MORE

  3. 3. The Baltic Sea Wave Field Impacts on the Sediment and Biogeochemistry

    University dissertation from Tema vatten i natur och samhälle

    Author : Anette Jönsson; Linköpings universitet.; Linköpings universitet.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydraulic engineering; HYPAS; Wave modelling; Significant wave height; Wave energy; Vattenteknik; TECHNOLOGY Civil engineering and architecture Water engineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Vattenteknik;

    Abstract : The wave field in the Baltic Sea has been modelled for a two-year period with the spectral wave model HYPAS. There is a large seasonal variation in the field and a minor annual one, both reflect the wind variation in the area. Since the Baltic Sea is fetch limited, the dominant wind direction is important for the maximum wave heights. READ MORE

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

    University dissertation from Stockholm : Department of Systems Ecology, Stockholm University

    Author : Johan Näslund; Stockholms universitet.; [2010]
    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; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology Marine ecology; NATURVETENSKAP Biologi Terrestrisk; limnisk och marin ekologi Marin ekologi; Marine Ecotoxicology; marin ekotoxikologi;

    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. 5. Effect of environmental factors on bacterioplankton community composition, diversity and functionality

    University dissertation from Växjö, Kalmar : Linnaeus University Press

    Author : Johanna Sjöstedt; Linnéuniversitetet.; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mikrobiologi; Microbiology; Akvatisk ekologi; Aquatic Ecology; marine microbiology; bacterioplankton; community composition; diversity; functionality; environmental factors; disturbance; distribution;

    Abstract : The ocean covers more than 70 % of the Earth surface and represents the largest ecosystem on Earth. Bacteria are an important part of the marine food web not only in remineralisation but also since they utilize dissolved organic matter (DOM) and make the energy available to higher trophic levels.
