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.

4. 3. DNA adductomics: Method development and integration in biological effect monitoring

   Författare :Giulia Martella; Elena Gorokhova; Hitesh V. Motwani; Brita Sundelin; Gunnar Boysen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DNA adducts; Nucleic acids; High-resolution mass spectrometry; Data-independent acquisition; Biological effect monitoring; Environmental contaminants; Biomarkers; Amphipods as sentinel species; Environmental Sciences; miljövetenskap;

   Sammanfattning : Environmental omics can provide informative biomarkers for identifying pathologies or physiological responses to environmental change. Nucleic acid adductomics, one of the newest omics techniques, is particularly well suited for assessing exposure and effects of environmental contaminants because the technique can capture modifications at the (epi)genome level.

5. 4. Coping with environmental change : Lessons from isotope studies in a sentinel species

   Författare :Matias Ledesma; Agnes Karlson; Marleen De Troch; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; stable isotope; compound-specific nitrogen stable isotope analysis; trophic niche; harmful algae blooms; contaminants; stress; reproductive success; environmental change; Baltic Sea; marin ekologi; Marine Ecology;

   Sammanfattning : Adaptive evolution and phenotypic plasticity are two key mechanisms by which natural populations avoid extinction in the face of environmental change. Evolutionary young systems, such as the Baltic Sea with low species diversity and steep environmental gradients, are good models for studying how wild populations cope with environmental changes, such as climate-induced alterations in food supply and exposure to environmental contaminants.

7. 5. Deposit-feeding in benthic macrofauna : Tracer studies from the Baltic Sea

   Författare :Lars Byrén; Ragnar Elmgren; Lisa A. Levin; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Deposit-feeding; Macrofauna; Baltic Sea; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

   Sammanfattning : A low content of organic matter, which is largely refractory in nature, is characteristic of most sediments, meaning that aquatic deposit-feeders live on a very poor food source. The food is derived mainly from sedimenting phytodetritus, and in temperate waters like the Baltic Sea, from seasonal phytoplankton blooms. LÄS MER
