    Sammanfattning : Wood is a natural raw material, and would hardly be considered a risk to the environment. However, the handling of wood materials on an industrial scale has been shown to have a negative impact on water bodies that run-off from industrial sites that process wood-based materials. LÄS MER

  5. 4. Bacterioplankton population dynamics in a changing ocean

    Författare :Markus V. Lindh; Jarone Pinhassi; Pierre Galand; Linnéuniversitetet; []

    Sammanfattning : Bacterioplankton is characterized by high diversity, short generation times and rapid turnover. Despite their small size, these numerous microorganisms are a fundamental piece of aquatic ecosystems by channeling carbon to higher trophic levels through dissolved organic matter utilization.
