1. Baltic benthos communities and the role of the meiofauna
Sammanfattning : .... LÄS MER
2. Filamentous cyanobacteria in the Baltic Sea - spatiotemporal patterns and nitrogen fixation
Sammanfattning : Summer blooms of filamentous, diazotrophic cyanobacteria are typical of the Baltic Sea Proper, and are dominated by Aphanizomenon sp. and the toxic Nodularia spumigena. Although occurring every summer, the blooms vary greatly in timing and spatial distribution, making monitoring difficult and imprecise. LÄS MER
3. Deposit-feeding in benthic macrofauna : Tracer studies from the Baltic Sea
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
4. The neglected ecology of the sand goby: Abundance and feeding in the Baltic sublittoral
Sammanfattning : I investigated the ecology and population density of the sand goby, Pomatoschistus minutus, at sub-thermocline depth in the north-western Baltic proper. Most previous research on the sand goby, and the co-occurring closely related common goby, P. LÄS MER
5. Benthic use of phytoplankton blooms: uptake, burial and biodiversity effects in a species-poor system
Sammanfattning : Animals living in marine sediments (the second largest habitat on earth) play a major role in global biogeochemical cycling. By feeding on organic matter from settled phytoplankton blooms they produce food for higher trophic levels and nutrients that can fuel primary production. LÄS MER
