2. 1. Drivers of carbon sink function in tropical seagrass beds : influence of carbon import, plant composition, seascape configuration and human activities

   Author : Rashid O. Ismail; Mats Björk; Martin Gullström; Maria E. Asplund; Amelia S. Buriyo; Matern S.P. Mtolera; Teresa Alcoverro; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon sequestration; tropical seagrass meadows; coastal seascape; landscape configuration and transformation; calcification; allochthonous carbon; community respiration; carbon sink; human disturbance; coastal conservation; Plant Physiology; växtfysiologi;

   Abstract : Seagrass meadows are effective carbon sinks, sequestering atmospheric CO2 and capturing allochthonous organic material, storing organic carbon (Corg) in their sediments, so called Blue Carbon. In tropical areas, seagrass meadows have a high number of calcareous organisms, which can offset carbon sequestration by releasing CO2 through their calcification. READ MORE

4. 2. Genetic Aspects of Environmental Disturbances in Marine Ecosystems : Studies of the Blue Mussel in the Baltic Sea

   Author : Josefine Larsson; Mats Grahn; Inger Porsch-Hällström; Katarzyna Smolarz; Andrew Whitehead; Södertörns högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Blue mussel; Baltic Sea; anthropogenic disturbance; pollution; sewage effluents; harbors; genetics; genomics; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

   Abstract : Anthropogenic environmental changes can serve as drivers for evolutionary responses in wild populations. To predict the long-term impact of anthropogenic changes on populations, it is crucial to understand the genetic effects caused by these disturbances. READ MORE

5. 3. Road Ecology for Environmental Assessment

   Author : Mårten Karlson; Berit Balfors; Ulla Mörtberg; Jo Treweek; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Roads; Railways; Biodiversity; Environmental Assessment; GIS; Decision Support; Mark- och vattenteknik; Land and Water Resources Engineering;

   Abstract : Transport infrastructure is closely linked to several politically relevant sustainability issues, and since 1985 a formalized environmental assessment process is linked to planning and construction of new roads and railways in the EU (EU directives 85/337/EEC and 2001/42). The aim of the environmental assessment process is to think in advance; to identify, predict and evaluate significant environmental changes resulting from a proposed activity, in order to adjust the proposed activity accordingly and to avoid unnecessary and unexpected consequences.

6. 4. Environmental Technology and its Role in the Search for Urban Environmental Sustainability : The Dynamics of Adaptation

   Author : Santiago Mejía-Dugand; Olof Hejlm; Leenard Baas; Julio Dávila; Linköpings universitet; []
   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Technology Adaptation; Governance Mechanisms; Spread of Technology; Stakeholder Involvement; Proof-of-concept; Environmental Technology Suppliers; Urban Imaginaries;

   Abstract : The aim of this thesis is to analyze the role that environmental technology plays in the solution of environmental problems in cities, and discuss models and conditions that can facilitate the processes of selection, implementation and use of environmental technologies in and by cities.The technological component is perhaps one of the most important characteristics of modern cities.

7. 5. Turbulent ship wakes and their spatiotemporal extent

   Author : Amanda Nylund; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; shipping; ship wake; turbulence; environmental impact;

   Abstract : Shipping activities occur in almost every part of the global oceans and in intensely trafficked shipping lanes there can be up to one ship passage every ten minutes. All these ships impact the marine environment in different ways through pollution or physical disturbance. READ MORE
