1. 1. Trophic ecology of meiofauna : Response to sedimentation of phytoplankton blooms in the Baltic Sea

   Författare :Francisco J.A. Nascimento; Ragnar Elmgren; Richard Warwick; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Meiofauna; Cyanobacteria; competition; facilitation; ecosystems processes; Marine ecology; Marin ekologi; Marine Ecology; marin ekologi;

   Sammanfattning : Marine soft sediments are the second largest habitat on Earth. How animal communities in this habitat are structured is a central issue in marine ecology. Food is an important limiting factor for many benthic populations, and settling organic matter from phytoplankton blooms is of vital importance to them. LÄS MER

3. 2. Benthic-pelagic coupling in a changing world : Structural and functional responses of microbenthic communities to organic matter settling

   Författare :Séréna Albert; Francisco J. A. Nascimento; Monika Winder; Stefano Bonaglia; Tom Moens; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Soft sediments; benthic-pelagic coupling; organic matter export; meiofauna; nitrogen cycle; metabarcoding; Baltic Sea; Marine Ecology; marin ekologi;

   Sammanfattning : Marine soft sediments form the second largest habitat on the planet. Organisms residing in this environment represent a vast reservoir of biodiversity, and play key roles in ecosystem processes. LÄS MER

4. 3. Microbenthos under Pressure : Impacts of human activities on bacteria and meiofauna communities in Baltic soft sediments

   Författare :Sven Iburg; Francisco J. A. Nascimento; Owen Wangensteen; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; soft sediments; benthic ecosystems; anthropogenic disturbance; contamination; recreational boating; bottom trawling; meiofauna; bacteria; metabarcoding; Baltic Sea; mjuka sediment; bentiska ekosystem; antropogenisk påverkan; förorening; fritidsbåtar; bottentrålning; meiofauna; bakterier; metabarcoding; Östersjön; marin ekologi; Marine Ecology;

   Sammanfattning : The marine benthic zone is one of the largest habitats on the planet, harbouring a large diversity of life that underpin many important ecological processes. However, these habitats have been under growing stress from human activities, profoundly altering their living communities. LÄS MER

5. 4. Ecological succession of benthic macrofauna following disturbance : Effects of contaminants and in situ sediment remediation

   Författare :Caroline Raymond; Jonas S. Gunnarsson; Agnes M. L. Karlson; Francisco J. A. Nascimento; Joanna Norkko; Gert Van Hoey; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Activated carbon; Benthos; Bioturbation; Contaminants; Environmental indices; Environmental monitoring; Environmental quality; Seafloor integrity; Sediment remediation; marin ekologi; Marine Ecology;

   Sammanfattning : More than 70% of the Earth is covered by water, and most of the sea floor consists of soft sediments, such as mud, clay and sand. Thus, soft sediments form one of the most important habitats on Earth, with a high diversity of organisms. LÄS MER

7. 5. Sediment remediation using activated carbon: amending knowledge gaps

   Författare :Robert A. Rämö; Jonas S. Gunnarsson; Agnes M. L. Karlson; Francisco J. A. Nascimento; Barbara Beckingham; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; sediment contamination; sediment remediation; sorbent amendment; activated carbon; benthic community; macroinvertebrates; Baltic Sea; Marine Ecotoxicology; marin ekotoxikologi;

   Sammanfattning : Many coastal sediments have accumulated large quantities of contaminants from past anthropogenic activities and now act as a secondary emission source of legacy pollutants to coastal ecosystems. New sediment remediation strategies are needed to address widespread sediment pollution. LÄS MER
