  1. 1. Changing population distribution in Sweden long term trends and contemporary tendencies

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Johan Håkansson; Högskolan Dalarna.; Umeå universitet.; [2000]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Population Distribution; Concentration; Dispersion; Accessibility; Migration; Natural increase; Population distribution; redistribution; Sweden; geographical levels; concentration; dispersion; accessibility; migration; natural population change; age composition;

    Sammanfattning : The aim of the thesis is to describe and analyse the population redistribution in Sweden at different geographical levels from the beginning of the 19th century to the end of the 20th century. The analysis is approached in three different ways. First, the redistribution at different geographical levels is analysed (papers I and II). LÄS MER

  2. 2. The role of microclimate for the performance and distribution of forest plants

    Detta är en avhandling från Stockholm : Department of Ecology, Environment and Plant Sciences, Stockholm University

    Författare :C. Johan Dahlberg; Stockholms universitet.; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; performance; microclimate; spatial scales; continental; landscape; distribution patterns; distribution limits; phenology; vegetative development; reproductive development; vital rates; population growth rate; vascular plants; bryophytes; distribution modelling; Plant Ecology; växtekologi;

    Sammanfattning : Microclimatic gradients may have large influence on individual vital rates and population growth rates of species, and limit their distributions. Therefore, I focused on the influence of microclimate on individual performance and distribution of species. LÄS MER

  3. 3. Biofilms in Nitrogen Removal - Bacterial Population Dynamics and Spatial Distribution

    Detta är en avhandling från Göteborg : University of Gothenburg

    Författare :Robert Almstrand; Göteborgs universitet.; Gothenburg University.; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; AOB; NOB; biofilms; image analysis; FISH; Nitrosomonas; population dynamics; spatial distribution;

    Sammanfattning : Efficient nitrogen removal at wastewater treatment plants (WWTPs) is necessary to avoid eutrophication of recipient waters. The most commonly used approach consists of aerobic nitrification and subsequent anaerobic denitrification resulting in the release of dinitrogen gas into the atmosphere. LÄS MER

  4. 4. Ecology and genetic population structure of Indo-Pacific bottlenose dolphins in East Africa

    Detta är en avhandling från Stockholm : Department of Zoology, Stockholm University

    Författare :Anna Särnblad Hansson; Stockholms universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Tursiops aduncus; population size; distribution; social structure; behaviour; conservation status; mitochondrial DNA; microsatellites; Zanzibar; western Indian Ocean; NATURAL SCIENCES; NATURVETENSKAP; Animal Ecology; zoologisk ekologi;

    Sammanfattning : Many marine mammal populations are threatened by anthropogenic activities. The Indo-Pacific bottlenose dolphins (Tursiops aduncus) off Zanzibar are subject to high levels of bycatch, negative impact from tourism and were previously hunted. LÄS MER

    Sammanfattning : The breakthrough for mechanized weaving in Sweden occured during the 1850's. Rapidly increasing quantities of cotton-textiles had to reach customers in a country with a scattered population and substansial social and economic differences between various parts of the country.
