  3. 2. Spatial Vision in Birds: Anatomical investigation of spatial resolving power

    Författare :Mindaugas Mitkus; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Raptors; Seabirds; Parrots; Birds; Double cones; Development; Retinal ganglion cells; Visual spatial resolution; Visual ecology; Vision;

    Sammanfattning : Avian eyes are big both in relative and absolute terms, thus the importance of vision to birds is obvious. Even though the general eye plan is rather conservative throughout the group, there is a great variation in visual capabilities. LÄS MER

  4. 3. Evolution of olfaction in Lepidoptera and Trichoptera : Gene families and antennal morphology

    Författare :Jothi Kumar Yuvaraj; Funktionell zoologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; evolution; pheromone receptors; olfaction; chemosensory; sensillum; HEK 293 cells;

    Sammanfattning : In moths, females produce sex pheromone compounds to attract males over a long distance for mating. The antennae of moths and many other insects have specialized odorant receptors (ORs), called pheromone receptors (PRs), to sense the pheromone compounds and they group in a monophyletic clade (PR clade).

  5. 4. Avian MHC: variation and selection in the wild

    Författare :Helena Westerdahl; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; polymorphism; balancing selection; cDNA; avian malaria; great reed warbler; Djurekologi; bird; Animal ecology; immune defence; MHC class II; Major Histocompatibility Complex; MHC class I;

    Sammanfattning : In vertebrates the Major Histocompatibility Complex (MHC) plays a central role in the specific immune defence against various pathogens. Compared with other coding genes the MHC genes exhibit an extremely high level of polymorphism that is maintained by balancing selection. LÄS MER

  7. 5. Neural Interfaces to the Odour World of Scarab Beetles

    Författare :Mattias Larsson; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Djurekologi; Animal ecology; Intra; Antennal lobe; CNS; Attraction; Olfactometer; Behaviour; Mass spectrometry; Gas chromatography; Electrophysiology; Single sensillum; Receptor neuron; Plant volatile; Sex pheromone; Neuroethology; Odour detection; Olfaction; Coleoptera; Scarabaeidae; Entomology; plant parasitology; Entomologi; växtparasitologi; Environmental chemistry; Miljökemi;

    Sammanfattning : Antennal detection and central nervous integration of behaviourally relevant odours in scarab beetles (Coleoptera: Scarabaeidae) was investigated, using the two Japanese scarabs Anomala cuprea and Phyllopertha diversa (Rutelinae), and the Central African fruit chafer Pachnoda marginata (Cetoniinae) as model species. Electrophysiological single cell recordings in A. LÄS MER
