  1. 1. Complementary feeding based on Nordic foods : effects on nutrient intake, growth, biomarkers and eating behavior

    Författare :Ulrica Johansson; Torbjörn Lind; Inger Öhlund; Lene Lindberg; Anna Winkvist; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Infant feeding; healthy diet; food preference; complementary feeding; eating behavior; repeated exposure; vegetables; fruit; Nordic diet; sustainable diet; nutrition; roots; berries; flavor learning; pediatrik; Pediatrics; Medicine; medicin; Nutrition; näringslära; Public health; folkhälsa;

    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

  3. 2. Forest Development and Interactions with Large Herbivores

    Författare :Christer Kalén; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Växtekologi; Plant ecology; modelling; preferences; browsing; deer; forestry; succession;

    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

  4. 3. Causes and consequences of niche differentiation between color morphs of pygmy grasshoppers

    Författare :Einat Karpestam; Anders Forsman; Birgitta Tullberg; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; color polymorphism; visual predators; Tetrix subulata; differential habitat use; niche; thermoregulation; feeding preferences; stable isotopes; Evolutionary Biology; Evolutionsbiologi;

    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.

  5. 4. Pine weevil feeding behaviour in relation to conifer plant properties

    Författare :Frauke Fedderwitz; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    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

  7. 5. Avian Malaria and Related Blood Parasites: Molecular Diversity, Ecology and Evolution

    Författare :Olof Hellgren; MEMEG; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diversity; Plasmodium; bird-migration; transmission; blackfly; host-specificity; host-preference; cytochrome b; DHFR-TS; recombination; phylogeny; Ecology; Ekologi; Genetics; cytogenetics; Genetik; cytogenetik; Parasitology human and animal ; Haemoproteus; Leucocytozoon; Parasitologi människa och djur ; Animal ecology; Djurekologi; Natural science; Naturvetenskap;

    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
