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

    Författare :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; []
    Nyckelord :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;

    Sammanfattning : 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.

  2. 2. Seagrass productivity : from plant to system

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

    Sammanfattning : 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. LÄS MER

  3. 3. Carbon sequestration processes in tropical seagrass beds

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

    Sammanfattning : 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.

  4. 4. Drivers of carbon sink function in tropical seagrass beds : influence of carbon import, plant composition, seascape configuration and human activities

    Författare :Rashid O. Ismail; Mats Björk; Martin Gullström; Maria E. Asplund; Amelia S. Buriyo; Matern S.P. Mtolera; Teresa Alcoverro; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon sequestration; tropical seagrass meadows; coastal seascape; landscape configuration and transformation; calcification; allochthonous carbon; community respiration; carbon sink; human disturbance; coastal conservation; Plant Physiology; växtfysiologi;

    Sammanfattning : Seagrass meadows are effective carbon sinks, sequestering atmospheric CO2 and capturing allochthonous organic material, storing organic carbon (Corg) in their sediments, so called Blue Carbon. In tropical areas, seagrass meadows have a high number of calcareous organisms, which can offset carbon sequestration by releasing CO2 through their calcification. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER
