  1. 26. Uppföjlning av SCA:s nya drivningsmetod "Skonsam Effektiv Drivning"

    Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Karolina Ottosson; [2017]
    Nyckelord :Markfuktighetskarta; GPS-loggning; Körskador; Drivning; Planering;

    Sammanfattning : Körskadeproblematiken inom skogsbruket har under flera år varit en prioriterad fråga. När körskador uppstår på skogsmarken på grund av drivning kan det ha oönskade effekter som t.ex. kvicksilverutlakning, tillväxtförluster och försämrade livsmiljöer för vattenlevande organismer.

  3. 27. Inelastic LIDAR for Monitoring Aquatic Fauna

    Master-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Författare :Mikael Ljungholm; [2016]
    Nyckelord :LIDAR; Laser; hyperspectral; multispectral; inelastic; ecology; monitoring; plankton; aquatic; Scheimpflug; Technology and Engineering;

    Sammanfattning : This thesis is oriented around designing the world first inelastic hyperspectral LiDAR(Light Detection and Ranging) system for aquatic use. The system was designed around the task of monitoring zooplankton and environmental indicators in water. Scheimpflug lidar was previously developed for monitoring flying insects, aerosols and gases.

  4. 28. Biodiversity assessment for coastal fish communities in the Baltic Sea

    Master-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Aline Vullioud; [2016]
    Nyckelord :biodiversity; Baltic Sea; coastal fish communities; biodiversity changes; size-class;

    Sammanfattning : Biodiversity becomes of increasing concern in management of marine ecosystems. Measures of biodiversity are numerous and have been largely developed. Biodiversity can be partitioned in different components that indicate, for example, spatial and temporal changes in any communities. LÄS MER

  5. 29. Investigating epifauna community assembly in shallow bays using traits

    Master-uppsats, Stockholms universitet/Institutionen för ekologi, miljö och botanik

    Författare :Ola Pettersson; [2016]
    Nyckelord :Ecology; Traits; Baltic Sea; Aquatic ecology; Shallow bays; Ekologi; Akvatisk ekologi; Östersjön; Egenskaper; Grunda vikar;

    Sammanfattning : Ecological studies are often performed to investigate ecosystems from a taxonomic point of view (e.g. species richness or species composition). However, investigating variations in organism traits, rather than variations based on taxonomy, can yield higher mechaninistic understanding of the ecosystem. LÄS MER

  7. 30. Spring ice melt effect on benthic oxygen production

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Tommy Karlsson; [2015]
    Nyckelord :Benthic; Oxygen; Ice release; Ecology;

    Sammanfattning : In biology, the winter season is less studied than other seasons partly due to technical and logistical difficulties. The Arctic region is undergoing rapid changes with shorter and warmer winters, shorter snow duration and considerable changes in snow and ice cover as a result. LÄS MER
