2. 1. 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

4. 2. Of seagrass and society : Exploring contributions of tropical seagrass meadows to food security

   Author : Benjamin Jones; Johan S. Eklöf; Lina M. Nordlund; Leanne C. Cullen-Unsworth; Richard K.F. Unsworth; Maricela de la Torre-Castro; Christina Hicks; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Biodiversity; Blue food; Food security; Social-ecological systems; Small-scale fisheries; Seagrass meadows; marinbiologi; Marine Biology;

   Abstract : Conserving biodiversity while simultaneously feeding a growing population is one of the grand challenges of the Anthropocene. Recently, global assessments have shone a light on the importance of the marine environment for the supply of food (often termed blue food), as well as the diverse and many livelihood opportunities associated to it.

5. 3. 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. 4. Carbon sequestration processes in tropical seagrass beds

   Author : Liberatus Dominick Lyimo; Mats Björk; Martin Gullström; Mariam Hamis; Teresa Alcoverro; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Seagrass; Carbon sequestration; Carbon sink; Eutrophication; Productivity; Nitrous oxide; Methane; Greenhouse gases; Tropical; Eastern Africa; Plant Physiology; växtfysiologi;

   Abstract : Seagrass meadows may play a substantial role in climate change mitigation as they are capable to sequester and store substantial amounts of anthropogenic carbon in plant biomass and, more importantly, in their underlying sediments. In this PhD thesis, the carbon-burial potential was assessed by quantifying the amount of organic carbon stored in different seagrass meadows, each dominated by one of the four major seagrass species in the Western Indian Ocean region.

7. 5. Swedish seagrass ecosystems in a changing climate : Coastal connectivity and global change sensitivity

   Author : Diana Perry; Martin Gullström; Jason Hall-Spencer; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; coastal seascape; shallow-water ecosystems; fish assemblages; connectivity; global change; climate change; multiple stressors; seagrass; Zostera marina; temperate region; Marine Ecology; marin ekologi;

   Abstract : Coastal shallow-water ecosystems are essential for providing several goods and services globally, with seagrasses as an important contributor for maintaining high biodiversity and productivity within the nearshore seascape. The temperate species Zostera marina serves as a vital habitat for many species, including ecologically and economically important juvenile fish. READ MORE
