  6. 4. Coastal Communities on the Move : House and Polity Interaction in Southern Ostrobothnia 1500 BC-AD 1

    Author : Peter Holmblad; Karin Viklund; Henrik Asplund; Umeå universitet; []

    Abstract : This work attempts to seek new insights in understanding the archeological phenomena traditionally labelled as the western Bronze Age and the coastal Pre-Roman cultures of Finland (1500 BC-AD 1), by studying the phenomena from a socioeconomic interaction and practice oriented community perspective. The basic line of thought is that it was the everyday life of the local agents and their interactions that constituted the local communities. READ MORE

  7. 5. Swedish seagrass ecosystems in a changing climate : Coastal connectivity and global change sensitivity

    Author : Diana Perry; Martin Gullström; Jason Hall-Spencer; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; coastal seascape; shallow-water ecosystems; fish assemblages; connectivity; global change; climate change; multiple stressors; seagrass; Zostera marina; temperate region; Marine Ecology; marin ekologi;

    Abstract : Coastal shallow-water ecosystems are essential for providing several goods and services globally, with seagrasses as an important contributor for maintaining high biodiversity and productivity within the nearshore seascape. The temperate species Zostera marina serves as a vital habitat for many species, including ecologically and economically important juvenile fish. READ MORE
