  1. 11. The Impact of Multiple Drivers on Marine Systems : Novel approaches for studying structural changes

    Författare :Johanna Yletyinen; Thorsten Blenckner; Örjan Bodin; Erik Bonsdorff; Daniel Stouffer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; naturresurshushållning; Natural Resources Management;

    Sammanfattning : Human action is transforming the species composition, biogeochemistry and habitats of the world’s oceans at unprecedented rates. The cumulative effect of natural and anthropogenic drivers is challenging to measure, in part due to indirect effects and the complexity of marine systems. LÄS MER

  4. 13. Spatial Modelling of Coastal Fish – Methods and Applications

    Författare :Göran Sundblad; Ulf Bergström; Alfred Sandström; Peter Eklöv; Christian Möllmann; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; habitat; niche; species distribution modelling; juvenile; fish; larvae; spawning; Marine ecology; Marin ekologi; NATURAL SCIENCES; NATURVETENSKAP; Freshwater ecology; Limnisk ekologi; Biology; Biologi; Biology with specialization in Limnology; Biologi med inriktning mot limnologi; Biologi med inriktning mot zooekologi; Biology with specialization in Animal Ecology; Limnologi; Limnology;

    Sammanfattning : Environmental factors influence species and habitats on multiple scales creating a mosaic of distribution patterns. Studying factors shaping these patterns are central to our understanding of population dynamics and ultimately ecosystem functioning. LÄS MER

  5. 14. Diazotrophy and diversity of benthic cyanobacteria in tropical coastal zones

    Författare :Karolina Bauer; Birgitta Bergman; Paul K. Hayes; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Marine cyanobacteria; benthic nitrogen fixation; diversity; diazotrophy; Lyngbya majuscula; Zanzibar; western Indian Ocean; Plant physiology; Växtfysiologi;

    Sammanfattning : Discoveries in recent years have disclosed the importance of marine cyano-bacteria in the context of primary production and global nitrogen cycling. It is hypothesized here that microbial mats in tropical coastal habitats harbour a rich diversity of previously uncharacterized cyanobacteria and that benthic marine nitrogen fixation in coastal zones is substantial.

  7. 15. Mapping bathymetry : From measurement to applications

    Författare :Benjamin Hell; Martin Jakobsson; Michele Rebesco; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ocean and coastal mapping; Digital Bathymetric Model; Geographical Information System; Applications of bathymetric data; Baltic Sea; Arctic Ocean; Seafloor morphology; Ocean circulation; Other earth sciences; Övrig geovetenskap; Marine Geoscience; marin geovetenskap;

    Sammanfattning : Surface elevation is likely the most fundamental property of our planet. In contrast to land topography, bathymetry, its underwater equivalent, remains uncertain in many parts of the World ocean. Bathymetry is relevant for a wide range of research topics and for a variety of societal needs. LÄS MER
