  1. 6. Temperature dependent preening behaviour in common guillemots Uria aalge

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Saga-Savanna Kynman; [2023]
    Keywords : common guillemot; common murre; seabirds; Stora Karlsö; heatstress; temperature; preening; allopreening;

    Abstract : As global temperature increase, new thermal conditions may challenge the physiological limits of endotherms. Examining the direct effects of extreme temperatures is an important component in understanding how these physiological limits may impact an organism’s behaviour, breeding success and survival.

  3. 7. Body patterning and cognition in cephalopods - a literature review

    University essay from SLU/Dept. of Animal Environment and Health

    Author : Georgina Chu; [2023]
    Keywords : cephalopods; octopus; body patterning; colour alteration; chromatophores; pigment cells; cognition; learning and memory;

    Abstract : Cephalopods are a valuable model for studying the evolution of cognition due to their distinctive brain structure, organisation, and connectivity patterns compared to vertebrates. The development of large brains and behavioural complexities are believed to be triggered by evolutionary pressures stemming from factors like heightened predation, more demanding foraging conditions, and intense mating competition.

  4. 8. Sharing space with a larger relative : examining interspecific effects of fallow deer on roe deer performance

    University essay from SLU/Dept. of Ecology

    Author : John-Christophe Hessler Frelinckx; [2023]
    Keywords : roe deer; fallow deer; interspecific competition; population densities;

    Abstract : Interspecific competition of some form is a part of life for most species across the world. For some species it can be part of their evolutionary history over many thousands of years, while for others it is a more recent experience, as is the case of roe deer (Capreolus capreolus) and fallow deer (Dama dama), in Scandinavia.

  5. 9. Thermal tolerance of native vs. invasive marine species at the Northern coast of Portugal

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Sofie Michelsen; [2023]
    Keywords : Biodiversity; Climate change; Marine ecosystems; Marine heat waves; Intertidal environment; Invasive species; Macroalgae; Mussels; Sustainable Development; Thermal tolerance;

    Abstract : Two prominent factors posing a major threat to biodiversity in marine ecosystems are climate change and the establishment of invasive species, and the interaction between these two. Because of the upwelling of cold, nutrient-rich water, the coast of Portugal is a thermal refuge and distribution edge for cold-adapted species, making it a particularly important study area from a biodiversity point of view.

  6. 10. Respiratory Motion Correction in PET Imaging: Comparative Analysis of External Device and Data-driven Gating Approaches

    University essay from KTH/Fysik

    Author : Nina Lindström Söraas; [2023]
    Keywords : PET CT; Tomographic reconstruction; Respiratory gating techniques; Image registration; Motion correction; PET CT; Tomografisk rekonstruktion; Gating tekniker; Bildregistrering; Rörelsekorrigering;

    Abstract : Positron Emission Tomography (PET) is pivotal in medical imaging but is prone to artifactsfrom physiological movements, notably respiration. These motion artifacts both degradeimage quality and compromise precise attenuation correction. READ MORE
