  1. 1. Transcriptomic profiling of marine bacteria between development and senescence phases of a phytoplankton bloom

    University essay from Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Author : Dennis Amnebrink; [2018]
    Keywords : Transcriptomics; bacteria; microbes; DOM; marine environment; bioinformatics;

    Abstract : Bacterioplankton provide important ecosystem functions by carrying out biogeochemical cycling of organic matter. Playing an important role in the microbial loop they help remineralize carbon and nutrients. Bacteria also interact with phytoplankton during phytoplankton blooms. READ MORE

  2. 2. Modelling vegetation dynamics and carbon fluxes in a high Arctic mire

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Laura Reinelt; [2015]
    Keywords : methane dynamics; biogeochemical cycling; vegetation dynamics; ecosystem modelling; LPJ-GUESS; geography; physical geography; high Arctic wetland; Zackenberg; Earth and Environmental Sciences;

    Abstract : High Arctic wetlands are an important component of the global climate system. Nevertheless estimations of their expected response to climate change and associated climate-feedbacks have large uncertainties. Improving models for vegetation and carbon dynamics of ecosystems is an important step towards making predictions more accurate. READ MORE

  3. 3. Effects of forestry on emission of CO2 from boreal lakes

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

    Author : Cecilia Larsson; [2013]
    Keywords : carbon dioxide; boreal lakes; forestry; dissolved organic carbon; global carbon cycling;

    Abstract : Inland waters have long been neglected in the global carbon cycle. They represent only 2,8%of the land area, but it has come clear that inland waters play a key role in the transformationof terrestrial fixed carbon to the atmosphere. READ MORE

  4. 4. Modeling of the Nitrogen Cyclein the Sediments of the Western Gotland Basin, Baltic Sea

    University essay from KTH/Industriell ekologi

    Abstract : Modeling of the nitrogen cycling in the sediments of the Baltic Sea is the major objective of thepresent study. A model of the nitrogen cycling in the sediment of the Western Gotland Basinwas developed. READ MORE

  5. 5. Simulation of Selenium Remobolisation and cycling in sediment

    University essay from KTH/Industriell ekologi (flyttat 20130630)

    Author : Erik Palm; [1997]
    Keywords : Modelling; selenium; biogeochemistry; bioturbation; sediment; pollutant fate; Lake Macquarie;

    Abstract : Lake Macquarie is the largest estuarine lake in New South Wales and is located on the eastern seaboard of Australia, approximately 85 km north of Sydney.The study of heavy metal concentrations in surficial sediments, sediment cores, seagrasses and fish conducted by the New South Wales Department of Mines in 1974 revealed that significant heavy metal contamination of Lake Macquarie has occurred.
