  1. 1. Seaward Landward : Investigations on the archaeological source value of the landing site category in the Baltic Sea region

    Författare :Kristin Ilves; Frands Herschend; Ingmar Jansson; Antony Firth; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; Archaeology; Coastal archaeology; Maritime archaeology; Maritime cultural landscape; Landing sites; Harbours; Critical historiography; Sociology of landing sites; Model of interaction; Methodology; Shore displacement; Phosphate analysis; Baltic Sea region; Archaeology; Arkeologi;

    Sammanfattning : There is a tendency in archaeology dealing with watercraft landing sites in a wider context to assume a direct relationship between sites in coastal and shore-bound areas and the practise of landing, without any deeper practical or theoretical exploration of the reality of any such relationship. This problem has its origins in the poor archaeological and conceptual definitions of watercraft landing sites obstructing any real understanding of the role of these sites in the maritime cultural landscape.

  3. 2. Migrant (‘dago’) fishers in coastal East Africa : understanding fisher migration and its role in artisanal fisheries

    Författare :Innocent Ngao Wanyonyi; Linnéuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Akvatisk ekologi; Aquatic Ecology;

    Sammanfattning : Coastal and marine resources support tourism and recreation, urbanizationand coastal development sectors as well as marine genetic resources and bioprospecting. Fishing remains the most important economic activity forprovision of food and income to coastal communities. LÄS MER

  4. 3. Technology and systems for stump harvesting with low ground disturbance

    Författare :Simon Berg; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Tree stumps could make a significant contribution to the transition from a fossil- to a bio-based economy, but current stump harvesting operations have adverse ecological effects. The ground disturbance caused by the up-rooting leads to increased carbon emissions from the soil and increases risks of leaching of heavy metals and nutrients, while removal of stump wood increases nutrient removal and reduces amounts of dead wood in the forest.

  5. 4. Semiochemical-mediated attraction and oviposition in pyralid moths

    Författare :Christian Olsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ekologi; Lepidoptera; behaviour; pest control; Ecology; learning; olfaction;

    Sammanfattning : Moths use chemical signals emanating from food to find sites for oviposition and subsequent larval feeding. By identifying these odours, novel approaches to pest management can be developed, such as monitoring of females in pest populations. LÄS MER

  7. 5. Humans and Seagrasses in East Africa : A social-ecological systems approach

    Författare :Maricela de la Torre-Castro; Nils Kautsky; Carl Folke; Patrik Rönnbäck; Edward H. Allison; Stockholms universitet; []
    Nyckelord :seagrasses; social-ecological systems; institutions; seaweed farming; artisanal fisheries; common-pool resources; natural resource management; Zanzibar; Tanzania; East Africa; Western Indian Ocean;

    Sammanfattning : The present study is one of the first attempts to analyze the societal importance of seagrasses (marine flowering plants) from a Natural Resource Management perspective, using a social-ecological systems (SES) approach. The interdisciplinary study takes place in East Africa (Western Indian Ocean, WIO) and includes in-depth studies in Chwaka Bay, Zanzibar, Tanzania. LÄS MER
