1. Marine Seaweed Invasions : the Ecology of Introduced Fucus evanescens
Sammanfattning : Biological invasions are an important issue of global change and an increased understanding of invasion processes is of crucial importance for both conservation managers and international trade. In this thesis, I have studied the invasion of the brown seaweed Fucus evanescens, to investigate the fate and effect of a perennial, habitat-forming seaweed introduced to a coastal ecosystem.

2. Marine seaweed invasions : Impacts and biotic resistance in native ecosystems
Sammanfattning : Marine seaweeds constitute one of the most productive plant systems known on Earth and a rich fauna including juvenile fish and crustaceans is dependent on the habitats they form. Human influence on marine costal ecosystems has resulted in large scale changes to the abundance and distribution of species, where species introductions constitute an obvious part. LÄS MER
3. Importance of blue mussels for biodiversity and ecosystem functioning in subtidal habitats
Sammanfattning : Blue mussels, Mytilus spp., occur on rocky and sedimentary shores worldwide where they often form dense aggregates. These assemblages change the local environment and create unique habitats. LÄS MER
4. The importance of biodiversity for ecosystem processes in sediments : experimental examples from the Baltic Sea
Sammanfattning : Aquatic sediments are, by surface, the largest habitat on Earth. A wide diversity of organisms inhabit these sediments and by their actions they have a large influence on and also mediate many ecosystem processes. LÄS MER
5. Scaling Marine and Water Management
Sammanfattning : This book is concerned with the linkages between legal systems and the complexity of nature. It explores how legal delimitations of ecosystems and diffusion of management across different levels of administration affects priorities and outcomes of natural resource management. LÄS MER
