11. Searching for food in complex environments : Integrating processes at multiple spatial scales
Sammanfattning : 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. LÄS MER
12. Oviposition strategies in butterflies and consequences for conservation
Sammanfattning : 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. LÄS MER
13. Recognition and modulation of olfactory signals in the noctuid moth spodoptera littoralis
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
14. Ecology of parasitoids and their hosts in oilseed rape fields
Sammanfattning : 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.

15. Symbiosis in Arbuscular Mycorrhizal Fungi : Unearthing genomic signatures
Sammanfattning : 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. LÄS MER
