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

2. Exploring the resilience in coral reefs
Sammanfattning : 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.

3. Macroalgal community dynamics on coral reefs : Implications for management
Sammanfattning : 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. LÄS MER
4. Coral reefs in the Anthropocene : The effects of stress on coral metabolism and symbiont composition
Sammanfattning : 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. LÄS MER
5. Benthic cryptofauna and internal bioeroders on coral reefs
Sammanfattning : 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. LÄS MER
