  1. 1. Macroalgal community dynamics on coral reefs Implications for management

    University dissertation from Stockholm : Department of Systems Ecology, Stockholm University

    Author : Erik Mörk; Stockholms universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Macroalgae; Coral Reefs; Herbivory; Nutrients; Ecosystem change; Fish; Sea Urchins; East Africa; Marine Ecotoxicology; marin ekotoxikologi;

    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

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

    University dissertation from Stockholm : Department of Systems Ecology, Stockholm University

    Author : Albert Norström; Stockholms universitet.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; resilience; alternative stable states; regimes; feedbacks; recruitment; coral reefs; marine ecosystem management; regime shifts; phase shifts; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology Marine ecology; NATURVETENSKAP Biologi Terrestrisk; limnisk och marin ekologi Marin ekologi; Natural Resources Management; naturresurshushållning;

    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.

  3. 3. Coral reefs in the Anthropocene The effects of stress on coral metabolism and symbiont composition

    University dissertation from Stockholm : Department of Systems Ecology, Stockholm University

    Author : Suzanne Faxneld; Stockholms universitet.; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Corals; Disturbance; Galaxea fascicularis; ITS2; Metabolism; mtDNA; Pollution; Porites lutea; Symbiodinium; Temperature; Turbinaria mesenterina; Vietnam; Marine Ecotoxicology; marin ekotoxikologi;

    Abstract : Coral reefs constitute some of the most prolific and diverse ecosystems on our planet, but also among the most threatened.This thesis investigates the effects of environmental stressors on corals’ metabolism and symbiont diversity. READ MORE

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

    University dissertation from Stockholm : Zoologiska institutionen

    Author : Helena Strömberg; Stockholms universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bioerosion; cryptofauna; coral; invertebrates; damselfish; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology; NATURVETENSKAP Biologi 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.

  5. 5. Exploring the resilience in coral reefs

    University dissertation from Stockholm : Department of Systems Ecology, Stockholm University

    Author : Jerker Lokrantz; Stockholms universitet.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Coral Reefs; Resilience; Functional Groups; Vulnerability; Overfishing; Ecosystem Indicators; Tanzania; Zanzibar; NATURAL SCIENCES Biology Terrestrial; freshwater and marine ecology Marine ecology; NATURVETENSKAP Biologi Terrestisk; limnisk och marin ekologi Marin ekologi; naturresurshushållning; Natural Resources Management;

    Abstract : Considering the unprecedented global decline of coral reefs concerns about their future existence are well-justified. Safeguarding ecological resilience (i.e. the capacity of ecosystems to absorb disturbance without changing their identity) has become a prime goal for management in order to combat further degradation of coral reefs.
