1. Marine seaweed invasions : Impacts and biotic resistance in native ecosystems
Abstract : 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. READ MORE

2. Fish in the coastal seascape : exploring ecological processes and connectivity for conservation of temperate fish communities
Abstract : The need to understand patterns and processes in the marine environment has never been so profound as today, particularly as anthropogenic pressures upon coastal regions are drastically affecting habitats and species across a vast range. One approach to further understand these patterns and processes is through the use of seascape ecology methods. READ MORE

3. Importance of blue mussels for biodiversity and ecosystem functioning in subtidal habitats
Abstract : 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. READ MORE

4. Effects of Marine Protected Areas on Tropical Seagrass Ecosystems
Abstract : Seagrass beds are highly productive coastal ecosystems that sustain a rich and diverse associated fauna and flora. Increasing anthropogenic pressures threaten seagrass ecosystems and have already led to major seagrass losses across the world. READ MORE

5. Coral Reef Habitats and Fish Connectivity : Implications for coastal management and fishery
Abstract : Coral reefs have one of the highest levels of biodiversity of all ecosystems in the world and are important for both human livelihood and food security throughout many tropical countries. However, due to increased anthropogenic pressure on marine ecosystems, especially during the last couple of decades, coral reefs have become critically over-fished, and many reefs are now in a degraded state and are facing additional future threats due to further over-exploitation, chemical pollution, sedimentation, and effects of climate change.
