2. 21. Macroalgal community dynamics on coral reefs : Implications for management

   Author : Erik Mörk; Nils Kautsky; Magnus Nyström; Tim R. McClanahan; Stein Fredriksen; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Macroalgae; Coral Reefs; Herbivory; Nutrients; Ecosystem change; Fish; Sea Urchins; East Africa; marin ekotoxikologi; Marine Ecotoxicology;

   Abstract : Although rather inconspicuous on healthy coral reefs, macroalgae form the basis of coral food webs. Today, macroalgae are generally increasing and many reefs undergo transitions from coral to macroalgal dominance resulting from e.g. enhanced nutrient loading or increased fishing. READ MORE

4. 22. Effects of Marine Protected Areas on Tropical Seagrass Ecosystems

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

   Abstract : 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. READ MORE

5. 23. Macroalgae in tropical seascapes : regulating factors and functions in the coastal ecosystem

   Author : Gustaf Lilliesköld Sjöö; Max Troell; Nils Kautsky; Lena Kautsky; Alina Szmant; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Macroalgae; Coral reefs; Nutrients; Herbivory; Ecological functions; East Africa; Regulating factors; Anthropogenic influence; Seaweed farming; Bioindicator; marin ekotoxikologi; Marine Ecotoxicology;

   Abstract : Although macroalgae usually are inconspicuous on pristine coral reefs, they often thrive on reefs that are subjected to various types of anthropogenic disturbance. This thesis consists of five papers and investigates how biomass and composition of macroalgal communities on coral reefs are affected by regulating factors, such as nutrient availability, herbivory, substrate availability and hydrodynamic forces.

6. 24. Just like couscous : Gender, agency and the politics of female circumcision in Cairo

   Author : Maria Frederika Malmström; Marita Eastmond; Aud Talle; Nordiska Afrikainstitutet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; anthropology; identity; gender; agency; embodiment; senses; body; sexuality; female circumcision; politics; social change; performativity; practice; political Islam; Egypt; Middle East; North Africa; anthropology; identity; gender; agency; embodiment; senses; body; sexuality; female circumcision; politics; social change; performativity; practice; political Islam; Egypt; Middle East; North Africa;

   Abstract : This dissertation explores how female gender identity is continually created and re-created in Egypt through a number of daily practices, of which female circumcision is central. In order to do so, the study inquires into the lived experiences and social meanings of female circumcision and femininity as narrated by women from lower class neighbourhoods in Cairo. READ MORE

7. 25. Fish community patterns in Tanzanian mangrove creeks

   Author : Augustine Mwandya; Martin Gullström; Olof Lindén; Stockholms universitet; []
   Keywords : Mangrove ecosystems; fish assemblages; Mugil cephalus; population genetics; spatial and seasonal variability; human disturbance; East Africa; NATURAL SCIENCES; NATURVETENSKAP; Animal Ecology; zooekologi;

   Abstract : Human beings have exploited the biota of mangrove systems for centuries and fish continue to be one of the main products harvested from these habitats. The assumption of mangroves functioning as recruitment areas for juvenile fish from neighbouring habitats such as seagrass beds and coral reefs is a common argument for conservation and management of mangrove ecosystems.
