  1. 6. Spatial distribution and conservation planning of seabed biological diversity

    Författare :Genoveva Gonzalez-Mirelis; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Spatial autocorrelation; ecological classifications; distribution modelling; biotopes; conservation planning; biodiversity surrogates; GIS; spatial ecology; benthos; fjord;

    Sammanfattning : Knowledge of spatial patterns of biota has become a commodity for conservation practitioners and spatial ecologists alike. This type of information enables the identification of representative and unique biological features (at some nominal scale) which itself constitutes the application par excellence of knowledge of biodiversity distribution as it relates to the design of reserve networks and the realization of spatial planning.

  3. 7. Modelling elements in conversion of solid fuels - fixed bed combustion and gaseous radiation

    Författare :Robert Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combustion; fixed bed; modelling; solid fuels; gas radiation;

    Sammanfattning : For a long heat and power production by combustion of solid fuels has time been an established technique. Environmental concern of emissions for NOx, SOx and other harmful species has caused an increasingly stricter legislation on the emission levels of the boilers. LÄS MER

  4. 8. Applications of ocean transport modelling

    Författare :Hanna Corell; Kristofer Döös; Björn Kjerfve; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ocean transport modelling; connectivity; particle-tracking; sediment transport; Forsmark; marine protected areas; MPA; stream functions; heat flux; wind forcing; Carcinus maenas; atmosfärvetenskap och oceanografi; Atmospheric Sciences and Oceanography;

    Sammanfattning : The advective motion of seawater governs the transport of almost everything, animate or inanimate, present in the ocean and those lacking the ability to outswim the currents have to follow the flow. This makes modelling of advective ocean transports a powerful tool in various fields of science where a displacement of something over time is studied. LÄS MER

  5. 9. Species distribution models : ecological applications for management of biodiversity

    Författare :Simon Hallstan; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Species distribution models are a group of methods often used to estimate consequences of global change, to assess ecological status and for other ecological applications. The main idea behind species distribution models is that the geographical distributions of species can, to a large part, be explained by environmental factors and that species distributions therefore can be predicted in time or space.

  7. 10. Global Changes and European Terrestrial Ecosystems

    Författare :Emmanuel Gritti; Institutionen för naturgeografi och ekosystemvetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; European species; Climatic risk; pedology; cartography; climatology; Fysisk geografi; geomorphology; Physical geography; Vegetation modelling; Pollen analysis; Plant invasion; geomorfologi; marklära; kartografi; klimatologi; Global Changes;

    Sammanfattning : Global environmental changes are topics of important societal concern and current scientific interest. These changes are driven by many different forcing and feedbacks occurring at various time and geographic scales and are largely influencing the various Earth systems. LÄS MER
