  1. 21. Standardization of the Compass Neuropils of the Australian Bogong Moth, Agrotis infusa

    University essay from Lunds universitet/Examensarbeten i molekylärbiologi

    Author : Liv de Vries; [2016]
    Keywords : Biology and Life Sciences;

    Abstract : Every summer the Australian Bogong moth migrates from southern Queensland to the Australian Alps in southern New South Wales. Other migrants such as the monarch butterfly use a time-compensated sun compass. However, the Bogong is nocturnal and only has access to skylight cues such as the moon, polarized light or the Milky Way. READ MORE

  3. 22. Biology of the diamondback moth (Plutella xylostella) and its future impact in Swedish oilseed rape production : a literature review

    University essay from SLU/Dept. of Ecology

    Author : Joakim Hermansson; [2016]
    Keywords : diamondback moth; Plutella xylostella; overwintering; climate; canola; oilseed rape; cosmopolitan pest; resistance; Brassica napus;

    Abstract : The biology of the Diamondback moth, Plutella xylostella, and its impact on oilseed rape production is reviewed. The Diamondback moth, DBM, is a serious, migratory, pest and a problem worldwide because its larval stage has a ravenous appetite, which causes major economic losses in Brassica crops. READ MORE

  4. 23. Previously undiscovered neurons of the Bogong moth brain: 3D-reconstruction and registration

    University essay from Lunds universitet/Examensarbeten i molekylärbiologi

    Author : Olle Claesson; [2016]
    Keywords : Biology and Life Sciences;

    Abstract : The Australian Bogong moths are thought to have the ability to sense the earth’s magnetic field. This ability has to be reflected in the animal’s neural architecture. Hence reconstruction of three brain neurons was carried out, though these respond to visual stimulation instead of magnetic. READ MORE

  5. 24. Design and Implementation of a Glider Control System

    University essay from KTH/Optimeringslära och systemteori

    Author : Hannah Lindberg; [2015]
    Keywords : ROBEX; MOTH; glider; buoyancy; OBC; actuators; pitch; deflection; AHRS;

    Abstract : ROBEX is a unique research project combining Airbus Defence and Space’s robotics expertise with deep-sea exploration technology to discover more about the most extreme environments environments known to man. As a part of this project, a deep-sea glider called MOTH, is under development with the objective to determine whether gliders can be used as a platform for bathymetric and electromagnetic soundings of the seafloor as well as for new water column research.

  6. 25. Transgenerational phenotypic plasticity: can parental host plant experience affect the phenotype of the offspring? : a study in behavior and physiology in Spodoptera littoralis

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Axel Rösvik; [2015]
    Keywords : transgenerational phenotypic plasticity; Spodoptera littoralis; performance; migration; preference;

    Abstract : The Darwinian theory of natural selection first popularized by Charles Darwin in the mid-19th century has been widely accepted as one of the key mechanisms of evolution. However, before Darwin other scientists such as Jean-Baptiste de Lamarck had their theories about evolution. READ MORE
