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

    Author : C. Johan Dahlberg; Kristoffer Hylander; Johan Ehrlén; Jason D. Fridley; []
    Keywords : 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;

    Abstract : 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. READ MORE

  2. 2. Urban shades of green Current patterns and future prospects of nature conservation in urban landscapes

    University dissertation from Stockholm : Department of Systems Ecology, Stockholm University

    Author : Sara Borgström; Regina Lindborg; Sara Cousins; Thomas Elmqvist; Christer Nilsson; [2011]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; urbanisation; nature conservation; urban planning; urban systems; nature reserves; Sweden; NATURAL SCIENCES; NATURVETENSKAP; Natural Resources Management; naturresurshushållning;

    Abstract : Urban nature provides local ecosystem services such as absorption of air pollutants, reduction of noise, and provision of places for recreation, and is therefore crucial to urban sustainable development. Nature conservation in cities is also part of the global effort to halt biodiversity decline. READ MORE

  4. 4. Epigenetic mechanisms of asthma and allergy

    University dissertation from Stockholm : Karolinska Institutet, Dept of Medicine, Solna

    Author : Nathalie Acevedo; Karolinska Institutet.; Karolinska Institutet.; [2015]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Abstract : Allergic diseases such as atopic eczema (AE) and asthma are chronic inflammatory disorders in which the regulation of the immune system is altered, in concert with disease-specific defects in target organs. Their inception requires gene-environment interactions but the molecular mechanisms contributing to the pathogenesis remain unclear. READ MORE

  5. 5. Small biotopes: Landscape and management effects on pollinators

    University dissertation from Centre for Environmental and Climate Research (CEC) and Department of Biology, Faculty of Science, Lund University

    Author : Annika Söderman; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Agri-environmnetal scheme; management; agriculture; landscape complexity; heterogeneity; landscape scale; mall biotopes; field boundaries; pollinating insects; pollination; bumblebees; solitary bees; hoverflies;

    Abstract : The intensification of agriculture during the second half of the twentieth century, has caused sever declines of farmland biodiversity, where loss of semi-natural habitats is one of the major drivers. To halt further loss of habitat and biodiversity, agri-environmental schemes (AES) are used to compensate farmers to use methods less harmful to the environment. READ MORE
