2. 11. Effects of contrasting types of marine protected areas on seagrass- and coral communities : are community-based reserves an important complement to government-managed protected areas?

   Author : Angelica Chirico; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; marin ekotoxikologi; Marine Ecotoxicology;

   Abstract : Coastal ecosystems, including seagrass beds and coral reefs, are among the most ecological and economical important ecosystems on Earth. At the same time as these ecosystems support livelihoods of coastal communities they are being highly degraded worldwide. READ MORE

4. 12. Fishing for sustainability : Towards transformation of seagrass-associated small-scale fisheries

   Author : Sieglind Wallner-Hahn; Maricela de la Torre-Castro; Christina Hicks; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; small-scale fisheries; co-management; social-ecological systems; ecosystem services; institutions; transformation; seagrass meadows; destructive gear; food-web interactions; marin ekotoxikologi; Marine Ecotoxicology;

   Abstract : Small-scale fisheries employ many millions of people around the world, and are particularly important in developing countries, where the dependency on marine resources is high and livelihood diversification options are scarce. In many areas of the world however, small-scale fisheries are at risk which threatens the food security and wellbeing of coastal people. READ MORE

5. 13. Natural and human-induced carbon storage variability in seagrass meadows

   Author : Martin Dahl; Martin Gullström; Miguel A Mateo; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Blue carbon sequestration; Carbon storage variability; Seagrass meadows; Anthropogenic disturbances; Climate change; marin ekologi; Marine Ecology;

   Abstract : Seagrasses are considered highly important CO2 sinks, with the capacity to store substantial quantities of organic carbon in the living biomass and sediments, and thereby acting as a buffer against climate change. In this thesis, I have studied carbon storage variability in temperate and tropical seagrass habitats and identified factors influencing this variation. READ MORE

6. 14. Effects of community- and government-managed marine protected areas on tropical seagrass and coral communities

   Author : Angelica Chirico; Johan Eklöf; Nils Kautsky; Even Moland; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; coastal ecosystems; conservation; marine spatial planning; locally managed; fisheries closure; benthic communities; fish; foundation species; macroalgae; secondary succession; life-history; trait variability; plasticity; tourism; human disturbance; fishing; experimental research; Western Indian Ocean; causal modelling; structural equation model; permanova; multivariate data; marin ekotoxikologi; Marine Ecotoxicology;

   Abstract : Tropical seagrass beds and coral reefs are among the most productive and diverse ecosystems on Earth and provide ecosystem services, such as fish production and coastal protection, and support livelihoods of millions of people. At the same time, these ecosystems are threatened globally by anthropogenic disturbances, such as overfishing, pollution and global warming. READ MORE

7. 15. Seagrass productivity : from plant to system

   Author : Diana Deyanova; Mats Björk; Mirta Teichberg; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Seagrass; Chlorophyll a fluorescence; Ageing; Productivity; Seasonality; Stress response; Plant Physiology; växtfysiologi;

   Abstract : Seagrasses form one of the most productive habitats on earth and are recognized as very efficient carbon sinks. The levels and patterns of productivity within and across different seagrass systems vary widely due to natural or human-induced factors. READ MORE
