  1. 6. Chemical communication in mating shore crabs Carcinus maenas

    Författare :Mattias Ekerholm; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Zoology; Urine communication; Behavior; Spatial scale; Male pheromone; Primer pheromone; Zoologi; Olfaction;

    Sammanfattning : Locating and evaluating a suitable partner for mating is one of the most important events in any sexually reproducing organism. To achieve this, an animal must be able to locate its partner over both long and short distances, and finally evoke the proper mating behaviour. LÄS MER

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

    Författare :C. Johan Dahlberg; Kristoffer Hylander; Johan Ehrlén; Jason D. Fridley; Stockholms universitet; []
    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

  4. 8. Conceptualising Solutions in Business Networks: The Case of Heavy Vehicle Maintenance

    Författare :Klas Hedvall; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Heavy Vehicle Maintenance; Temporal Embeddedness; Spatial Embeddedness; Solutions; ARA Model; Interaction Centric; Business Networks; Industrial Network Approach;

    Sammanfattning : This thesis problematises and conceptualises the phenomenon of solutions in business networks based on processual approaches to solutions and the Industrial Network Approach to business markets. In particular, the thesis focuses on the interorganisational and interactive aspects involved in solutions embedded in business networks. LÄS MER

  5. 9. Linking plant population dynamics to the local environment and forest succession

    Författare :Johan Petter Dahlgren; Johan Ehrlén; Ove Eriksson; Mark Rees; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Actaea spicata; Forest herbs; Forest succession; Integral projection model; Plant demography; Plant phenology; Population dynamics; Pre-dispersal seed predation; Seed mass; Soil potassium; Specific leaf area; Terrestrial ecology; Terrestisk ekologi; Plant Ecology; växtekologi;

    Sammanfattning : Linking environmental variation to population dynamics is necessary to understand and predict how the environment influences species abundances and distributions. I used demographic, environmental and trait data of forest herbs to study effects of spatial variation in environmental factors on populations as well as environmental change in terms of effects of forest succession on field layer plants.

  7. 10. Strengthening conservation through green infrastructure : linking protected areas, habitats and species

    Författare :Ewa Orlikowska; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The green infrastructure (GI) concept was developed to mitigate habitat fragmentation. The European Union (EU) defines GI as “a strategically planned network of natural and semi-natural areas …designed and managed to deliver a wide range of ecosystem services and to improve connectivity of protected areas in order to promote multifunctional landscapes”.
