  2. 6. Phylogenomic Analysis of Vertebrate Evolution

    Author : Björn Hallström; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mammals; phyogenetics; phylogenomics; vertebrates; evolution;

    Abstract : The field of phylogenomics has emerged during the last five years, as the number of fully or partially sequenced genomes has increased rapidly. Using whole genomes for phylogenetic studies greatly increases the accuracy of the trees determined, and can potentially resolve phylogenetic questions that could not be resolved bu studies using only a few gene sequences.

  4. 7. Involvement of the immune system in phytohaemagglutinin-induced structural and functional precocious maturation of the gut in young rats

    Author : Olena Prykhodko; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; cytokines; mucosa; development; Gastrointestinal tract; mammals; immune system; T-cells;

    Abstract : Mammals are born with an immature gastrointestinal (GI) tract that allows the uptake of the specific nutrients and bioactive macromolecules in the milk, especially the protecting maternal antibodies. Eventually during weaning, the intake of milk decreases while that of solid food increases, and the GI system undergoes prominent structural and functional changes adapting the young this dietary change.

  5. 8. Myonuclear Organization and Regulation of Muscle Contraction in Single Muscle Fibres : Effects of Ageing, Gender, Species, Endocrine Factors and Muscle Size

    Author : Rizwan Qaisar; Lars Larsson; Jo Bruusgaard; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; single muscle cells; muscle nuclei; specific force; species; hypertrophy; mammals; ageing; gender; Physiology; Fysiologi;

    Abstract : The skeletal muscle fibre is a syncitium where each myonucleus regulates the gene products in a finite volume of cytoplasm i.e., the myonuclear domain (MND). READ MORE

  6. 9. Spatial Strategies for Biodiversity Conservation

    Author : André Pinto da Silva; Mats Bjõrklund; Greta Bocedi; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; global change; Southern Asia; mammals; ecological modelling; Biology with specialization in Animal Conservation; Biologi med inriktning mot zoologisk bevarandebiologi;

    Abstract : Biodiversity is being lost under alarming rates due to an unsustainable socio-economic trajectory causing global change. Such loss is unequally spread over the Earth, and Southern Asia has been and is projected to continue to be one of the most affected regions. READ MORE

  7. 10. Diversity and Limits of Colour Vision in Terrestrial Vertebrates

    Author : Lina Roth; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Reptiles; Dim light vision; Colour vision; Camera-type eyes; Vertebrates; Mammals; Geckos; Horses;

    Abstract : Most terrestrial vertebrates have colour vision, some perceive a less colourful world and others actually discriminate a wider colour spectrum than humans do. Still, we can all make use of the valuable colour information, which is more rigid than just brightness. READ MORE
