  1. 1. Reef Futures : Exploring the dynamics of transformative change in marine social-ecological systems

    Author : Franciska von Heland; Per Olsson; Beatrice Crona; Marja Spierenburg; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; transformative change; marine governance; multi-stakeholder collaboration; multi-level governance; institutional entrepreneurship; boundary work; narratives; Coral Triangle; Sustainability Science; vetenskap om hållbar utveckling;

    Abstract : The thesis explores issues relating to transformative change in the context of marine governance in the Coral Triangle, and the effects of such change processes on policy, stakeholder relations and management activities. Paper 1 studies how change-oriented actors (institutional entrepreneurs) operating at the international level can introduce and purposefully navigate large-scalechange processes. READ MORE

  2. 2. Coral Reef Habitats and Fish Connectivity : Implications for coastal management and fishery

    Author : Tove Lund Jörgensen; Michael Tedengren; Nick Graham; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; anthropogenic disturbance; coral reef habitat; fish community; coastal ecosystems; conservation management; spatial ecology; seascape perspective; holistic approach; marin ekotoxikologi; Marine Ecotoxicology;

    Abstract : Coral reefs have one of the highest levels of biodiversity of all ecosystems in the world and are important for both human livelihood and food security throughout many tropical countries. However, due to increased anthropogenic pressure on marine ecosystems, especially during the last couple of decades, coral reefs have become critically over-fished, and many reefs are now in a degraded state and are facing additional future threats due to further over-exploitation, chemical pollution, sedimentation, and effects of climate change.

  3. 3. Upholding the coral loop : Resilience, alternative stable states and feedbacks in coral reefs

    Author : Albert Norström; Magnus Nyström; Nancy Knowlton; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; resilience; alternative stable states; regimes; feedbacks; recruitment; coral reefs; marine ecosystem management; regime shifts; phase shifts; Marine ecology; Marin ekologi; naturresurshushållning; Natural Resources Management;

    Abstract : Coral reefs are suffering unprecedented declines in coral cover and species diversity. These changes are often associated with  substantial shifts in community structure to new dominant organisms. Ultimately, these “phase shifts” can be persistent and very difficult to return from.

  4. 4. Habitat structure, degradation and management effects on coral reef fish communities

    Author : Saleh A.S. Yahya; Martin Gullström; Sören Nylin; Narriman Jiddawi; Yunus Mgaya; Gunilla Rosenqvist; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fish assemblages; climate change; coral degradation; Indian Ocean; patch reefs; coral bleaching; resilience; zoologisk ekologi; Animal Ecology;

    Abstract : Coral reefs are among the most diverse and productive ecosystems on earth, and are critical to the survival of tropical marine ecosystems and sustenance of local human populations. However, coral reefs are quite vulnerable to disturbances, both natural and anthropogenic. READ MORE

  5. 5. Benthic cryptofauna and internal bioeroders on coral reefs

    Author : Helena Strömberg; Charlotta Kvarnemo; Pat Hutchings; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bioerosion; cryptofauna; coral; invertebrates; damselfish; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Abstract : The cryptofauna of coral reefs may act as a food source for fish, while being grazers or predators themselves, and hence constitute an important group in the coral reef food web. In addition, the actively eroding taxa of the cryptofauna contribute to the decomposition and recirculation of calcium carbonate and are consequently essential for the rebuilding new coral. READ MORE
