  2. 21. Studies on new tuberculosis vaccine candidates in animal models

    Author : Melles Haile; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Background: Tuberculosis (TB) is a major health problem in many countries, especially in low income countries. Globally, TB causes more than 2 million human deaths annually and 1/5 of all adult deaths in developing countries. WHO estimates that one third of the world's population i.e. READ MORE

  4. 22. Zoom in on the precision livestock farming

    Author : Keni Ren; Johannes Karlsson; Hibo Li; Matti Pastell; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; precision livestock farming; computer vision; sensor fusion; object tracking; real-time location system; animal behaviour; machine learning;

    Abstract : Global attention to the welfare of zoo animals and livestock results in stronger legislation and higher pressure for achieving higher standards of animal welfare. Monitoring and understanding animal behaviour can assist in optimising the welfare of zoo and livestock animals. READ MORE

  5. 23. Magnetic map sense in animals: effects of geographic and magnetic displacements

    Author : Jannika Boström; Biologiska institutionen; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Oenanthe oenanthe; skylight polarization; geomagnetic map; geomagnetic field; endogenous migration programme; migratory fuelling; orientation; animal navigation;

    Abstract : Migration research is a large and diverse field and in my thesis I have focused on the impact of geomagnetic cues on animal orientation, navigation and migratory fuelling. Several animal species from widely different taxa possess the ability to sense and make use of geomagnetic information during migratory or homing events. READ MORE

  6. 24. In the wake of a bird - Quantifying aerodynamic performance of avian flight

    Author : Marco Klein Heerenbrink; Evolutionär ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; animal flight; flight performance; gliding; powered flight; wing morphology; aerodynamics; biomechanics; birds; jackdaw; Corvus monedula; wind tunnel; PIV;

    Abstract : Flight is an expensive form of locomotion, but also offers the ability to travel great distances at relatively low cost. Birds have developed various adaptations for optimizing flight performance. The main aim of this thesis is to identify how morphological variables in birds affect aerodynamic drag and flight performance. READ MORE

  7. 25. Bottlenecks and blowflies : Speciation, reproduction and morphological variation in Lucilia

    Author : Ann-Britt Florin; Lisa Meffert; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Population size; speciation; Lucilia sericata; morphological variation; Lucilia illustris; bottlenecks; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Animal Ecology; zooekologi;

    Abstract : This thesis attempts to improve our understanding of the role of population size for the process of speciation. First, the effect of population size on speciation is studied using several meta-analyses of published laboratory experiments. READ MORE
