  1. 6. Mechanistic aspects of host plant preference in butterflies

    Författare :Alexander Schäpers; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; zoologisk ekologi; Animal Ecology; etologi; Ethology; zoologi; Zoology;

    Sammanfattning : Searching and locating resources is essential for survival. In herbivorous insects search behavior is conducted on several scales, requiring input and integration of information from different sensory modalities. LÄS MER

  3. 7. Pyralid moth reproduction: Communication, Constraints & Control

    Författare :Camilla Ryne; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; plant parasitology; Entomology; växtparasitologi; Entomologi; Animal ecology; Djurekologi; Chemistry; Kemi;

    Sammanfattning : Olfactory cues play an important role in the reproduction of three pyralid moths, the Indian meal moth (Plodia interpunctella), the Mediterranean flour moth (Ephestia kuehniella) and the almond moth (E. cautella). Both males and females of P. interpunctella are capable of multiple matings. LÄS MER

  4. 8. Traits or species – space or environment : how to understand the spatial structure of springtail community composition

    Författare :Lina Ahlbäck Widenfalk; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : How communities are structured and the processes shaping species composition are among the basic questions in ecology. Knowledge about these processes is essential to predict changes in community composition in response to changes in for example climate or land use practices. LÄS MER

  5. 9. Recognition and modulation of olfactory signals in the noctuid moth spodoptera littoralis

    Författare :Ahmed Saveer; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Food, mates and host plants are essential resources for plant-feeding insects. Optimal resource localization that fulfils the physiological need and reproductive goals of an insect is of utmost importance. LÄS MER

  7. 10. The genomic basis of the response to female-limited X-chromosome evolution

    Författare :Yesbol Manat; Evolutionär ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; X chromosome; Sex chromosome; Drosophila melanogaster; Experimental evolution; sexual selection; intralocus sexual conflict;

    Sammanfattning : In this thesis, I attempted to achieve a better understanding of the nature of X-linked polymorphic loci using a female-limited X chromosome (FLX) experimental evolution in Drosophila melanogaster. I expected that expressing the evolved X chromosome will result in an increase in female fitness and a decrease in male fitness. LÄS MER
