1. Complementary feeding based on Nordic foods : effects on nutrient intake, growth, biomarkers and eating behavior
Sammanfattning : Background: Early nutrition is fundamental to growth and development. Infants develop long lasting food preferences very early in life from food exposures when the brain is impressionable and sensory pathways are receptive. LÄS MER
2. Forest Development and Interactions with Large Herbivores
Sammanfattning : This thesis discusses aspects of feeding habits of moose (Alces alces) and their impact on forest development. The development of forage that is available to moose was studied by sampling the amount of edible biomass on pine and birch trees. LÄS MER
3. Causes and consequences of niche differentiation between color morphs of pygmy grasshoppers
Sammanfattning : In this thesis, I used the color polymorphic pygmy grasshopper, Tetrix subulata, as a model system in order to investigate the degree of niche differentiation between alternative color morphs that are present within a single population. First, I hypothesized that individuals belonging to different color morphs differ in their innate food preference due to somewhat dissimilar physiology, and in their actual food consumption due in part to differential habitat use.

4. Pine weevil feeding behaviour in relation to conifer plant properties
Sammanfattning : The pine weevil (Hylobius abietis (L.)) is a forest insect distributed over the Palearctic region. The adults feed on the phloem of young conifer plants causing high economic losses for the European forest industry. Still, there is very little knowledge about the structure of its feeding behaviour. LÄS MER
5. Avian Malaria and Related Blood Parasites: Molecular Diversity, Ecology and Evolution
Sammanfattning : Malaria-like parasites consist of a large group of species that infects primates, rodents, bats, lizard and birds. I have focused on parasites from the genera Haemoproteus, Plasmodium and Leucocytozoon that are infecting birds. LÄS MER
