11. Effects of community- and government-managed marine protected areas on tropical seagrass and coral communities
Sammanfattning : 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. LÄS MER
12. Fish for Food and Ecosystem Function : Fisheries, Trade and Key Ecosystem Processes in Coral Reefs
Sammanfattning : Fish is a key source of food and income to millions of people living along tropical coastlines. They also play essential roles underpinning key ecosystem processes in coral reefs. For example, herbivorous fish keep algae in check that otherwise may outcompete corals, reducing the reef’s social-ecological values. LÄS MER
13. Seagrasses in warming oceans : physiological and biogeochemical responses
Sammanfattning : The exponential increase of atmospheric greenhouse gas concentrations over the past 50 years has caused a rise in the global average temperature by more than 1ºC above pre-industrial levels. Ninety-three percent of this heat energy has been absorbed and stored by the oceans, increasing their temperatures, particularly in surface waters. LÄS MER
14. The Location and Variability of Southern ocean Fronts
Sammanfattning : The location of fronts has a direct influence on both the physical and biological processes in the Southern Ocean. Moreover, the Subtropical Front (STF) is believed play a key role in the global climate system. LÄS MER
15. Exploring Disaster Recovery: Stakeholder Interfaces, Goals and Interdependencies
Sammanfattning : Disaster risk management has seen the importance of coordination at various levels of planning and implementation, ranging from preparedness to disaster response, and in planning for long term recovery and sustainable development. This thesis aims to develop a deeper and analytical understanding of stakeholder coordination for disaster recovery. LÄS MER
