2. 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

4. 2. Biomarkers for assessing benthic pollution impacts in a subtropical estuary, Mozambique

   Author : Maria Perpétua Janeiro Scarlet; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; subtrophical estuary; contaminants; biological hierarcial biomarkers; scope for growth; burrowing response; acethylcholinesterase; benthic fauna; southern Mozambique;

   Abstract : This thesis focuses on the marine environment in a subtropical estuary and particularly on exploring a suite of easy-to-use, cost effective and environmentally valid biological response tools (biomarkers). The main driving force of the thesis is the knowledge of the numerous anthropogenic impacts. READ MORE

5. 3. Transport by Benthic Macrofauna: Functional Classification and Biogeochemical Response

   Author : Stina Lindqvist; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Marine sediments; Early diagenesis; Bioturbation; Functional groups; Benthic fluxes; Imaging; Ecosystem function; Sediment reworking; Transport proxies; Fluorescent particles;

   Abstract : Burrowing and reworking activities by benthic macrofauna regulate rates and pathways during organic matter mineralisation in bioturbated sediments. In so doing, they also affect the overall cycling of elements crucial in the biosphere (e.g. C, N, P, Fe, Mn and S). READ MORE

   Author : Jacob Hagberg; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES;

   Abstract : .... READ MORE

7. 5. Benthic use of phytoplankton blooms: uptake, burial and biodiversity effects in a species-poor system

   Author : Agnes M. L. Karlson; Ragnar Elmgren; Carlo Heip; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; biodiversity; ecosystem functioning; benthic-pelagic coupling; niche; resource partitioning; competition; eutrophication; cyanobacterial blooms; diatoms; invasive species; Baltic Sea; Marine ecology; Marin ekologi; Marine Ecology; marin ekologi;

   Abstract : Animals living in marine sediments (the second largest habitat on earth) play a major role in global biogeochemical cycling. By feeding on organic matter from settled phytoplankton blooms they produce food for higher trophic levels and nutrients that can fuel primary production. READ MORE
