1. 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

Silver and downy birch are the most common broadleaf tree species in northern Europe. In Sweden, the two species together make up approximately 12% of the standing forest volume. LÄS MER
4. Coated Norway Spruce : Influence of Wood Characteristics on Water Sorption and Coating Durability
Sammanfattning : Wood used outdoors is often degraded and discoloured by microorganisms as a natural part of its life cycle, particularly when exposed to high levels of moisture for prolonged times. In this case, the application of a coating (i.e. paint) is an option for increasing the service life of the wood. LÄS MER
5. Capture-based mud crab (Scylla serrata) aquaculture and artisanal fishery in East Africa- Practical and ecological perspectives : Mud crab ecology and aquaculture
Sammanfattning : Mud crab Scylla serrata is a crustacean that spends most of its life cycle in the mangrove environment throughout its range. Fishery and aquaculture of this crab are significant economic activities in coastal areas in the tropics and sub-tropics because of the meat quality and nutritional value. LÄS MER
