  2. 1. Aquatic vegetation in coastal ecosystems : The role of biotic interactions and environmental change for ecosystem functions and resilience in the Baltic Sea

    Author : Åsa Austin; Johan S. Eklöf; Joakim P. Hansen; Serena Donadi; Matthew E. S. Bracken; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; biodiversity; ecosystem functions; ecosystem multifunctionality; water clarity; fish recruitment; functional traits; feedbacks; biotic interactions; competition; facilitation; foundation species; seagrass; macrophytes; lagoons; brackish water; Baltic Sea; marin ekologi; Marine Ecology;

    Abstract : Coastal ecosystems are among the most productive on Earth but subjected to many human pressures. In shallow coastal areas, aquatic vegetation constitutes foundation species that sustain secondary production and act as a nutrient filter, which may buffer human impacts. READ MORE

  4. 2. Anthropogenic Disturbances and Shifts in Tropical Seagrass Ecosystems

    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.
