  1. 1. Ecological connectivity in East African seascapes

    Författare :Charlotte Berkström; Nils Kautsky; Susan S. Bell; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; fish; functional group; food-web interactions; nursery; coral; seagrass; mangrove; landscape ecology; Marine Ecotoxicology; marin ekotoxikologi;

    Sammanfattning : Coral reefs, seagrass beds and mangroves constitute a complex mosaic of habitats referred to as the tropical seascape. Great gaps exist in the knowledge of how these systems are interconnected. This thesis sets out to examine ecological connectivity, i.e. LÄS MER

  2. 2. Effects of Marine Protected Areas on Tropical Seagrass Ecosystems

    Författare :Elisa Alonso Aller; Johan S Eklöf; Charlotte Berkström; Martin Gullström; Glenn Hyndes; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; coastal ecosystems; seagrass; marine protected areas; management; conservation; fish; herbivory; Western Indian Ocean; East Africa; tropical; marin ekologi; Marine Ecology;

    Sammanfattning : Seagrass beds are highly productive coastal ecosystems that sustain a rich and diverse associated fauna and flora. Increasing anthropogenic pressures threaten seagrass ecosystems and have already led to major seagrass losses across the world. LÄS MER

  3. 3. Identification and implications of fish nurseries in tropical and subtropical seascapes

    Författare :Linda Eggertsen; Charlotte Berkström; Nils Kautsky; Johan Eklöf; Simon Pittman; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; marinbiologi; Marine Biology;

    Sammanfattning : Many species of reef fish reside in specific nursery habitats as juveniles. Seagrass meadows, and mangroves are examples of well-recognized nursery habitats, but only recently canopy-forming seaweeds have been found to provide important habitats for some fish species in the tropics.

  4. 4. Introduced and indigenous macroalgae : Ecological effects, functions and regulating factors in tropical seascapes

    Författare :Maria Eggertsen; Christina Halling; Charlotte Berkström; Johan Eklöf; Jennifer Smith; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; macroalgae; introduced species; coral-algae interactions; nursery habitats; herbivory; Eucheuma denticulatum; tropical seascape; marin ekologi; Marine Ecology;

    Sammanfattning : Tropical marine shallow-water areas are highly productive systems that promote important ecological functions and biodiversity. Stressors on these systems are intensifying due to increasing anthropogenic disturbances on multiple scales. LÄS MER
