  1. 1. Laser Based Flow Measurements to Evaluate Hydraulic Conditions for Migrating Fish and Benthic Fauna

    Author : S M Sayeed Bin Asad; Staffan Lundström; J. Gunnar I. Hellström; Anders G. Andersson; Berhanu Mulu Geberkiden; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fish Migration; Step Cylinder; Shedding; Vortex Street; Shear stress; PIV; benthic fauna; river; stones; Strömningslära; Fluid Mechanics;

    Abstract : Hydropower is one of the main sources for Sweden’s energy, which is clean and renewable. It is a clean energy source because no fuels are burned which does not pollute the air and it is a renewable energy source as it only uses natural water cycle for generating energy. READ MORE

    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

  4. 4. Wave energy conversion and the marine environment : Colonization patterns and habitat dynamics

    Author : Olivia Langhamer; Anders Berglund; Jan Sundberg; Andrew Gill; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; artificial reefs; benthos; biodiversity; biofouling; colonization; environmental impact; fish; shellfish; Mytilus edulis; renewable energy; wave power; Biology; Biologi; Animal Ecology; Zooekologi;

    Abstract : A wave energy park has been established on the Swedish west coast outside Lysekil and pioneer work about its interactions with the marine environment has been conducted. So far, little is known about the effects of offshore energy installations on the marine environment, and this thesis assists in minimizing environmental risks as well as in enhancing potential positive effects on the marine environment.

  5. 5. Novel approaches to the environments and ecosystems of the fish-tetrapod transition

    Author : Hannah Byrne; Per Ahlberg; Grzegorz Niedzwiedzki; Henning Blom; Benjamin P. Kear; Matt Friedman; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; fish-tetrapod transition; synchrotron scanning; tides; coprolites; Carboniferous;

    Abstract : The fish-tetrapod transition is one of the most important evolutionary events in Earth’s history, giving rise to terrestrial vertebrates around 390 million years ago. It set the stage for a series of evolutionary events that ultimately resulted in modern-day terrestrial vertebrates including ourselves. READ MORE
