1. 1. 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

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. Sex and symbionts : New discoveries in local and regional patterns of coral ecology and reproduction

   Författare :Micaela Hellström; Michael Tedengren; Mats Grahn; John A. H. Benzie; Nancy Knowlton; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Indo-Pacific; S. elegans; G. fascicularis; Symbiodinium; size; reproduction; allozymes; ITS2; mtDNA; geography; environment; Marine ecology; Marin ekologi; marin ekotoxikologi; Marine Ecotoxicology;

   Sammanfattning : Coral reefs belong to the most diverse and the most threatened ecosystems on earth. Anthropogenic stressors and climate change have led to mortalities at levels unprecedented in modern times. The aims of this thesis are to investigate aspects of the corals’ ability to reproduce, disperse, adapt and survive. LÄS MER

5. 4. 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

7. 5. Biology, ecology and anthropogenic threats of Indo-Pacific bottlenose dolphins in east Africa

   Författare :Omar A. Amir; Per Berggren; Graham Pierce; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Growth; reproduction; feeding ecology; bycatch; organohalogen compounds; dolphins; Tursiops aduncus; Zanzibar; East Africa; Marine ecology; Marin ekologi; zoologisk ekologi; Animal Ecology;

   Sammanfattning : This thesis examines the biology, ecology and anthropogenic threats of Indo-Pacific bottlenose dolphins (Tursiops aduncus) off Zanzibar, Tanzania, based on research conducted and samples collected between 2000 and 2008. Distribution and occurrence are described based on incidental catches (bycatch) in gillnet fisheries. LÄS MER
