2. 1. 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

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

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

   Abstract : 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. READ MORE

5. 3. Seaweed in the tropical seascape : Importance, problems and potential

   Author : Stina Tano; Christina Halling; Sofia Wikström; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Seaweed; Macroalgae; Eucheumoids; Non-indigenous; Haplotype; Fish; Nursery; Epifauna; Diversity; Seaweed farming; Zanzibar; East Africa; Tropical; marin ekotoxikologi; Marine Ecotoxicology;

   Abstract : The increasing demand for seaweed extracts has led to the introduction of non-native seaweeds for farming purposes in many tropical regions. Such intentional introductions can lead to spread of non-native seaweeds from farming areas, which can become established in and alter the dynamics of the recipient ecosystems. READ MORE

6. 4. Fish in the coastal seascape : exploring ecological processes and connectivity for conservation of temperate fish communities

   Author : Thomas Staveley; Martin Gullström; Mats Björk; Regina Lindborg; Emma Jackson; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; seascape ecology; landscape ecology; seagrass; marine habitats; fish; spatial analysis; connectivity; conservation; Sweden; temperate; Marine Ecology; marin ekologi;

   Abstract : The need to understand patterns and processes in the marine environment has never been so profound as today, particularly as anthropogenic pressures upon coastal regions are drastically affecting habitats and species across a vast range. One approach to further understand these patterns and processes is through the use of seascape ecology methods. READ MORE

7. 5. Ecological connectivity in East African seascapes

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

   Abstract : 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. READ MORE
