  2. 11. Intermittent fasting in chickens : Physiological mechanisms and welfare implications for broiler breeders

    Author : Caroline Lindholm; Jordi Altimiras; Ian Dunn; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Broiler breeder chickens are the parent stock used to produce broiler chickens raised for human consumption and have long been caught in a welfare dilemma. The immensely successful selection of fast-growing meat-type chickens over the last 80 years has created a remarkably efficient meat-producer and given us access to cheap chicken meat but has also created health problems for the animals.

  4. 12. Single-cell methodologies for ecological and metabolic mapping of mixotrophic microeukaryotes

    Author : Javier Florenza; Stefan Bertilsson; Alexandra Z. Worden; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; mixotrophy; single-cell;

    Abstract : Mixotrophy in aquatic protists is pivotal for our understanding of aquatic microbial food web dynamics. This thesis is centered around aquatic unicellular mixotrophs, and comprises three methodological approaches aimed to tackle mixotroph ecology at single-cell resolution: the identification of actively feeding mixotrophs in natural samples, the determination of specific interactions among mixotrophs and bacterial prey, and the profiling of two distinct mixotrophic populations based on the gene expression of their constitutive individuals.

  5. 13. Food choice in fallow deer – experimental studies of selectivity

    Author : Ulrika Alm Bergvall; Olof Leimar; Frederick D. Provenza; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; behavioural syndrome; neighbour contrast defence; neighbour contrast susceptibility; simultaneous negative contrast; plant secondary compounds; tannins; Ethology and behavioural ecology; Etologi och beteendeekologi; etologi; Ethology;

    Abstract : In this thesis, I experimentally investigate feeding selectivity in fallow deer (Dama dama), with respect to plant secondary compounds, especially tannins, which can decrease the quality of foods. I found that fallow deer avoided foods with higher amounts of tannic acid and Quebracho tannin, even though the deer ate some high-tannin food. READ MORE

  6. 14. Breastfeeding and introduction of other foods : A prospective longitudinal study in Sweden

    Author : Agneta Hörnell; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Obstetrics and gynaecology; accustoming; breastfeeding duration; chewing; coeliac disease; exclusive breastfeeding; feeding frequency; formula; night feeding; pacifier use; sleep; solids; suckling duration; thumb sucking; weaning; Obstetrik och kvinnosjukdomar; Obstetrics and women s diseases; Obstetrik och kvinnosjukdomar; pediatrik; Pediatrics;

    Abstract : This study, based on daily recordings of infant feeding, comprised 506 infants from Uppsala, Sweden. All mothers had had previous breastfeeding experience of at least 4 months, and were planning to breastfeed the index child for ≥6 months. READ MORE

  7. 15. 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
