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

2. Macroalgae in the Baltic Sea : responses to low salinity and nutrient enrichment in Ceramium and Fucus
Abstract : The brackish Baltic Sea is a marginal environment for both marine and freshwater species. The rate of ecological differentiation is presumably high due to strong selection pressure from a gradient of decreasing salinity that has been present in its current state for only about 3 000 years.

3. Effects of community- and government-managed marine protected areas on tropical seagrass and coral communities
Abstract : Tropical seagrass beds and coral reefs are among the most productive and diverse ecosystems on Earth and provide ecosystem services, such as fish production and coastal protection, and support livelihoods of millions of people. At the same time, these ecosystems are threatened globally by anthropogenic disturbances, such as overfishing, pollution and global warming. READ MORE

4. Introduced and indigenous macroalgae : Ecological effects, functions and regulating factors in tropical seascapes
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

5. Macroalgal community dynamics on coral reefs : Implications for management
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
