1. Hydroxylated polybrominated diphenyl ethers in Baltic Sea biota : Natural production, food web distribution and biotransformation
Sammanfattning : Hydroxylated polybrominated diphenyl ethers (OH-PBDEs) are naturally produced in aquatic ecosystems e.g. by algae. Many OH-PBDEs have been observed to be highly bioactive and to cause adverse effects through several pathways, e. LÄS MER
2. Towards understanding stable isotope signatures in stressed systems
Sammanfattning : Stable isotope analysis (SIA) is a valuable tool in ecotoxicology because δ13C and δ15N may provide insights into the trophic transfer of contaminants in a food web. The relationship between a species’ trophic position (TP, determined from δ15N) and internal concentration of biomagnifying contaminants can be established and used for regulatory purposes. LÄS MER
3. Pharmaecological perspectives : Exposure studies using coastal Baltic Sea organisms
Sammanfattning : This thesis investigates the effects of pharmaceutical substances on coastal Baltic Sea organisms. Despite an increasing awareness of the occurrence of pharmaceuticals in various aquatic compartments, current knowledge of their possible effects on non-target organisms is limited. LÄS MER
4. Grazing and the geographical range of seaweeds : The introduced Fucus evanescens and the newly described Fucus radicans
Sammanfattning : Along the coast of temperate oceans brown algae of the genus Fucus form dense stands on rocky shores and are keystone species of the coastal ecosystem. These large seaweeds are perennial and function as substrate for many sessile marine organisms, provide shelter for fauna and juvenile fish, and are food source. A number of abiotic (e.g. LÄS MER
5. Aspects of offshore renewable energy and the alterations of marine habitats
Sammanfattning : Several Western European countries are planning for a massive offshore renewable energy (i.e. wind and wave energy) development (ORED) along the European Atlantic coast and in the Baltic Sea. LÄS MER
