  1. 31. Sea cages, seaweeds and seascapes : Causes and consequences of spatial links between aquaculture and ecosystems

    Författare :Nils Hedberg; Tedengren Michael; Nils Kautsky; Barry Costa-Pierce; Stockholms universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Spatial links; Aquaculture; Coral Reefs; Seagrass; Seascape; marin ekotoxikologi; Marine Ecotoxicology;

    Sammanfattning : Aquaculture is of growing importance in the global seafood production. The environmental impact of aquaculture will largely depend on the type of environment in which the aquaculture system is placed. LÄS MER

  5. 34. Tracing and apportioning sources of dioxins using multivariate pattern recognition techniques

    Författare :Anteneh Assefa; Mats Professor; Karin Professor; Paul Professor; Patrik Andersson; Shigeki Masunaga; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polychlorinated dibenzo-p-dioxin; polychlorinated dibenzofuran; positive matrix fac- torization; PMF; principal component analysis; PCA; Baltic Sea; sediment core; PCDD F; sources; marine; fish; environmental half-live; peak year; peak level; temporal trend; spatial variation; coastal; offshore; chemical fingerprint; Environmental Science; miljövetenskap;

    Sammanfattning : High levels of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) in edible fish in the Baltic Sea have raised health concerns in the Baltic region and the rest of Europe. Thus, there are urgent needs to characterize sources in order to formulate effective mitigation strategies. LÄS MER

  7. 35. Climate change time machine : Adaptation to 30 years of warming in the Baltic Sea

    Författare :Friederike Ermold; Anssi Laurila; Jukka Jokela; Kerstin Johannesson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; climate change; thermal adaptation; evolution; Baltic Sea; Biotest Basin; ecological interactions; biological invasions; phenotypic plasticity; Biologi med inriktning mot populationsbiologi; Biology with specialization in Population Biology;

    Sammanfattning : Earth mean surface temperature has increased by 1 °C since the industrial revolution, and this has already had considerable effects on animal and plant species. Ecological responses to the warming climate – often facilitated via phenotypic plasticity – are ubiquitous. LÄS MER
