2. 1. Fish in the coastal seascape : exploring ecological processes and connectivity for conservation of temperate fish communities

   Author : Thomas Staveley; Martin Gullström; Mats Björk; Regina Lindborg; Emma Jackson; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; seascape ecology; landscape ecology; seagrass; marine habitats; fish; spatial analysis; connectivity; conservation; Sweden; temperate; Marine Ecology; marin ekologi;

   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

4. 2. Effects of Marine Protected Areas on Tropical Seagrass Ecosystems

   Author : Elisa Alonso Aller; Johan S Eklöf; Charlotte Berkström; Martin Gullström; Glenn Hyndes; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; coastal ecosystems; seagrass; marine protected areas; management; conservation; fish; herbivory; Western Indian Ocean; East Africa; tropical; Marine Ecology; marin ekologi;

   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. 3. Offshore wind farms - ecological effects of noise and habitat alteration on fish

   Author : Mathias H. Andersson; Sören Nylin; Magnus Wahlberg; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; renewable energy; fish population; artificial reef; attraction vs. production; habitat structure; reef effect; FAD; bioacoustics; noise disturbance; fish behaviour; detection range; threshold; masking; fish communication and hearing; Marine ecology; Marin ekologi; zoologisk ekologi; Animal Ecology;

   Abstract : There are large gaps in our understanding how fish populations are affected by the anthropogenic noise and the alteration of habitat caused by the construction and operation of offshore wind farms. These issues are of great importance as the construction of offshore wind farms will increase all over the world in the near future. READ MORE

6. 4. Effects of community- and government-managed marine protected areas on tropical seagrass and coral communities

   Author : Angelica Chirico; Johan Eklöf; Nils Kautsky; Even Moland; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; coastal ecosystems; conservation; marine spatial planning; locally managed; fisheries closure; benthic communities; fish; foundation species; macroalgae; secondary succession; life-history; trait variability; plasticity; tourism; human disturbance; fishing; experimental research; Western Indian Ocean; causal modelling; structural equation model; permanova; multivariate data; marin ekotoxikologi; Marine Ecotoxicology;

   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

7. 5. Marine seaweed invasions : Impacts and biotic resistance in native ecosystems

   Author : Josefin Sagerman; Sofia Wikström; Fransisco Arenas; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Plant invasion; exotic species; generalist herbivores; plant-herbivore interactions; enemy-release hypothesis; ecosystem function; marin ekotoxikologi; Marine Ecotoxicology;

   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
