  2. 11. Searching for food in complex environments : Integrating processes at multiple spatial scales

    Author : Thomas Alexander Verschut; Peter Hambäck; Peter Anderson; Ring Cardé; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Associational effects; Natal experiences; Olfaction; Oviposition; Plant Ecology; växtekologi;

    Abstract : Resources are often unevenly distributed through the environment, resulting in a challenging task for insects to locate food, mates and oviposition sites. Consequently, there is an ongoing need to unravel how insects rely on behavioural and sensory traits while searching for resources in heterogeneous environments. READ MORE

  4. 12. Oviposition strategies in butterflies and consequences for conservation

    Author : Anders Bergström; Sören Nylin; Jeremy A. Thomas; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Abstract : Oviposition strategies are an important component of life history evolution in insects. Oviposition is a complex behaviour, where females must locate suitable habitat patches, locate oviposition sites, evaluate the quality, and finally decide how many eggs to lay. READ MORE

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

    Author : Ahmed Saveer; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 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. READ MORE

  6. 14. Ecology of parasitoids and their hosts in oilseed rape fields

    Author : Josef Berger; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; parasitoids; herbivores; oilseed rape; pollen beetle; cabbage stem weevil; parasitoid community; niche separation; landscape scale; community composition; landscape configuration; Species abundance distribution SAD models; dispersal; metacommunity;

    Abstract : Oilseed rape fields are a very common crop in the agricultural landscape of southern Sweden, and they can harbour surprisingly many insect species. Some of them are herbivores that feed on various parts of the oilseed rape plant, others are natural enemies of the herbivores, and even more species are tourists from the surrounding landscape.

  7. 15. Symbiosis in Arbuscular Mycorrhizal Fungi : Unearthing genomic signatures

    Author : Shadi Eshghi Sahraei; Anna Rosling; Vasilis Kokkoris; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; arbuscular mycorrhizal fungi; mutualistic symbiosis; soil microeukaryotic communities; phylogenomics; single spore assembly; gene family evolution; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Arbuscular mycorrhizal (AM) fungi have been on earth since 470 million years ago. AM fungi form mutualistic symbiosis with most terrestrial plants and thus, are thought to have played important roles in land colonization together with plants. READ MORE
