2. 1. 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

4. 2. 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

5. 3. Evaluation of suitable nursery areas for penaeid shrimps in shallow water systems in southern Mozambique

   Author : Daniela de Abreu; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tropics; Southeast Africa; Shallow water; Estuaries; Nursery ground value; Decapods; Penaeidae; Carbon and nitrogen isotopes; Diet; Acetyl cholinesterase; Butyryl cholinesterase; Metals;

   Abstract : Tropical shallow water habitats such as estuaries, mangrove forests and seagrass beds are important nursery areas for juveniles of many commercially important species including penaeid shrimp. Penaeids are one of the most important fishery resources worldwide, and in Mozambique they are the basis of a profitable commercial fishery, landing hundreds of tons per year. READ MORE

6. 4. Ecology of juvenile turbot and flounder in the Central Baltic Sea : Implications for recruitment

   Author : Jesper Martinsson; Sture Hansson; Magnus Appelberg; Anders Nissling; Leif Pihl; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Psetta maxima; Platichthys flesus; juvenile; Baltic Sea; nursery ground; distribution; recruitment; Marine Ecology; marin ekologi;

   Abstract : Our understanding of turbot and flounder ecology in the Baltic Sea is insufficient for sound management decisions. This thesis aims to fill some gaps in current knowledge by providing information of the ecology of turbot and flounder within their juvenile habitat, and to relate these findings to issues assumed relevant for recruitment variation.

7. 5. 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
