  1. 6. Spatial Vision in Bees : Behavioural investigation of spatial resolution and contrast sensitivity

    Författare :Aravin Chakravarthi; Funktionell zoologi; []
    Nyckelord :Insect vision; Honeybees; Bumblebees; Spatial resolution; Contrast sensitivity; Motion detection; Object discrimination;

    Sammanfattning : Bees use multiple sensory modalities to perform day-to-day tasks. Light allows them to perceive objects and the general features of their surroundings, enabling them to find food and to navigate safely across the landscape. LÄS MER

  3. 7. On Identification of Biological Systems

    Författare :Egi Hidayat; Alexander Medvedev; Peter Stoica; Elling Jacobsen; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system identification; biomedical systems; insect vision; endocrine systems; orthogonal basis functions; time delay; impulse response; Laguerre functions; Laguerre polynomials; excitation design; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : System identification finds nowadays application in various areas of biological research as a tool of empiric mathematical modeling and model individualization. A fundamental challenge of system identification in biology awaits in the form of response variability. LÄS MER

  4. 8. The visual ecology of bees - Tales of diverse eyes and behaviours

    Författare :Pierre Tichit; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Animal behaviour; Arthropods; Bumblebees; Compound Eyes; Crystalline cones; Flight control; Image analysis; Landing; Sensory ecology; Stingless bees; Vision; X-ray microtomography;

    Sammanfattning : The buzzing flight of bees is a popular summer hit. Yet, outside of a few familiar species of honeybees and bumblebees, these fantastic little creatures are still mostly unknown. With about twenty-five thousand species, bees are a very diverse group. They can be found in drastically different habitats. LÄS MER

  5. 9. A behavioural investigation into Eristalis tenax : Pursuit, approach estimation, locomotor activity and rearing

    Författare :Malin Thyselius; Karin Nordström; Anna Rostedt Punga; Yuri Ogawa; Emily Baird; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Eristalis tenax; Insect rearing; Hoverflies; Pollinators; Circadian rhythm; Target detection; Motion vision; Pursuit; LAMS; Flight arena;

    Sammanfattning : Hoverflies are suggested to be the 2nd most important pollinator group after bees and bumblebees, and with the changing climate and dwindling numbers of pollinators it might never have been more important understanding our pollinators. Given the hoverflies’ small brains, beautiful aerial acrobatics, good temporal resolution, but limited spatial resolution, these flies make interesting study animals for flight behaviour and vision research.

  7. 10. Valorization of Low Value Organic Waste by the use of Black Soldier Fly Larvae – Bioconversion of Sludge from the Pulp and Paper Industry

    Författare :Robert Norgren; Anders Jonsson; Olof Björkqvist; William Hogland; Mittuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sustainable sludge management; bioconversion; insect protein;

    Sammanfattning : The current economic system is not sustainable, as it is based on a linear flow of resources from extraction, production, use and disposal. The linear flow of resources must be replaced with a circular flow where waste is seen as a resource. LÄS MER
