  1. 1. Biomarkers and bioindicators of hypoxia and sediment toxicity in Monoporeia affinis

    Författare :Marie Löf; Brita Sundelin; Tina Elfwing; Elena Gorokhova; Ingela Dahllöf; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biomarkers; Bioindicators; Embryo aberrations; Hypoxia; Contaminated sediment; PAHs; PCBs; Metals; Baltic Sea; Amphipods; Monoporeia affinis; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Two of the most pressing environmental problems in the Baltic Sea are pollution and oxygen deficiency. The aim of this doctoral thesis was to evaluate a set of biomarkers and reproductive variables in the amphipod Monoporeia affinis to test their suitability as indicators of exposure to contaminants and hypoxia.

  3. 2. Assessing environmental and contaminant stressors in a benthic amphipod

    Författare :Therese Jacobson; Brita Sundelin; Tamara Galloway; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Multiple stressors; Reproduction; Temperature; Food; Parasites; Fenarimol; PFOS; TBT; Endocrine disruption; Ecdysteroids; Microsporidia; Microcosm; Crustacea; Amhipoda; Monoporeia affinis; Biology; Biologi; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Organisms in the aquatic environment encounter numerous stressors throughout their lifespan. Some of them are biotic such as food availability, predators and parasites. Others are abiotic and include shifting salinity and temperature change among others. LÄS MER

  4. 3. Analysis of Perfluoroalkyl Acids in Swedish Biota : Temporal trends, tissue distribution and toxicity

    Författare :Katrin Holmström; Urs Berger; Gregg Tomy; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental chemistry; PFOS; PFAS; pollutant; Baltic guillemot; peregrine falcon; Monoporeia affinis; time trend; toxicity; Environmental chemistry; Miljökemi; Persistent organic compounds; Persistenta organiska föreningar; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Perfluorinated alkyl acids (PFAS) are ubiquitous environmental contaminants. They are found in high concentrations in top predators worldwide, with perfluorooctane sulfonate (PFOS) as the predominant compound. LÄS MER

  5. 4. Improved environmental monitoring and assessment : Establishing links between effects of chemical pollution at different levels of biological organization in a Baltic Sea bioindicator species (Monoporeia affinis)

    Författare :Martin Reutgard; Magnus Breitholtz; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Environmental health assessment; environmental monitoring; chemical pollution; hypoxia; bioindicators; biomarkers; teratogenicity; embryo toxicity; oxidative stress; acetylcholine esterase. Monoporeia affinis; Baltic Sea; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : A large number of chemicals enters the marine environment via atmospheric deposition, run-off, rivers and streams, industrial effluents and municipal wastewater. To understand how chemicals affect environmental health, monitoring and assessment approaches need to combine physical, chemical and biological effect parameters from different levels of biological organization.

  7. 5. Predatory processes in Baltic benthos

    Författare :Gunilla Ejdung; Susanne Baden; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; zoologisk ekologi; Animal Ecology;

    Sammanfattning : The Baltic soft-bottom community is uniquely simple, with only a few benthic macro-faunal species, and is therefore well suited for mechanistic studies of inter-specific interactions. Two of the dominating organisms in this benthic community are the amphipod Monoporeia affinis and the bivalve Macoma balthica. Field surveys have shown that M. LÄS MER
