  1. 31. How the sensory ecology of the bumblebee affects their functional traits

    Författare :Vun Wen Jie; Emily Baird; Mikael Carlsson; Martin How; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bumblebee; functional morphological traits; intraspecific differences; allometry; DRA; micro-CT; co-existence; Functional Zoomorphology; funktionell zoomorfologi;

    Sammanfattning : Morphological traits are important for trait-based ecological studies as they allow for the prediction of biodiversity across the biosphere. Currently, the predictive power of trait-based ecology is not often applied to terrestrial arthropods, even though they provide us with important agricultural, ecological, and cultural value.

  3. 32. Molecular and functional characterization of the insect hemolymph clot

    Författare :Malin Lindgren; Ulrich Theopold; Andreas Vilcinskas; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Innate immunity; hemolymph coagulation; transglutaminase; Molecular biology; Molekylärbiologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : All metazoans possess an epithelial barrier that protects them from their environment and prevents loss off body fluid. Insects, which have an open circulatory system, depend on fast mechanism to seal wounds to avoid excessive loss of body fluids. LÄS MER

  4. 33. Evaluation of the Rift Valley fever vaccination program in Mozambican cattle

    Författare :Belisário Moiane; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Rift Valley fever (RVF) is a viral disease that is spread by various arthropods (primarily mosquitoes) and affects ruminants and humans. RVF has led to tremendous losses of livestock in many African countries, Saudi Arabia, and Yemen, and its zoonotic impact on human deaths has been documented in most of the endemic countries where large outbreaks have occurred.

  5. 34. Effective conservation of biodiversity and ecosystem services in agricultural landscapes

    Författare :William Sidemo Holm; BECC: Biodiversity and Ecosystem services in a Changing Climate; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; biodiversity; ecosystem services; agri-environmental measures; cost-effectiveness; conservation;

    Sammanfattning : Agricultural land use is a major driver of biodiversity losses and changes in ecosystem services. Thus, for the sake of both humans and wild organism per se, effective strategies that enable both agricultural production and conservation of biodiversity and ecosystem services are urgently needed.

  7. 35. Host-pathogen interactions between Francisella tularensis and Drosophila melanogaster

    Författare :Malin Vonkavaara; Svenja Stöven; Ingrid Faye; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; arthropod vector; JNK; lipopolysaccharide; antimicrobial peptides; Clinical Bacteriology; klinisk bakteriologi; molekylärbiologi; Molecular Biology;

    Sammanfattning : Francisella tularensis is a highly virulent Gram-negative bacterium causing the zoonotic disease tularemia. Arthropod-borne transmission plays an important role in transferring the disease to humans. F. LÄS MER
