  1. 1. Drivers of flower size evolution in the selfing species Arabidopsis thaliana

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Clàudia Fernández Mestre; [2023]
    Keywords : Arabidopsis thaliana; petal size; fitness; selection; evolutionary drivers; GWAS;

    Abstract : The influence of pollinators on the evolution of flower morphology has been extensively explored. Yet, the effect of other ecological factors, such as genetic drift, environmental filtering, and allometric constraints, gained less attention. In this study, we addressed the importance of those drivers in a predominantly selfing species. READ MORE

  3. 2. The perfect wing, The perfect trade-off? : What implements the main selection pressure on wing morphology?

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Emme MacDonald; [2023]
    Keywords : Bird; wing morphology; migration; habitat; aspect ratio; wing loading;

    Abstract : Selection pressure is a constant force in evolution, pushing birds and their wings towards an optimal shape and structure, were increasing performance, and minimizing the costs is central. But even though the science of aerodynamics can provide calculations of the optimal construction for the wing in different situations this rarely directly correspond to what is observed in nature.

  4. 3. Predictive MR Image Generation for Alzheimer’s Disease and Normal Aging Using Diffeomorphic Registration

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Yuqi Zheng; [2023]
    Keywords : Medical Image Generation; Brain Aging; Diffeomorphic Registration; AlzheimerŠs Disease; Medicinsk bildgenerering; Åldrande av hjärnan; DiffeomorĄsk registrering; Alzheimers sjukdom;

    Abstract : Alzheimer´s Disease (AD) is the most prevalent cause of dementia, signifying a progressive and degenerative brain disorder that causes cognitive function deterioration including memory loss, communication difficulties, impaired judgment, and changes in behavior and personality. Compared to normal aging, AD introduces more profound cognitive impairments and brain morphology changes. READ MORE

  5. 4. Assessing the potential impacts of tall buildings on a predominantly low-rise built urban environment : A case study from Västerås, Sweden

    University essay from Umeå universitet/Institutionen för geografi

    Author : Vera Schwab; [2022]
    Keywords : Tall buildings; The City Image; 3D modelling; GIS; Shadow Analysis; Visibility Analysis; Västerås;

    Abstract : Tall buildings have been constructed in many cities over the world to accommodate the demographic and economic growth in urban areas. These structures, however, have been widely discussed concerning their potential negative impacts on urban life. READ MORE

  6. 5. INDIVIDUAL TRAIT MATCHING OF BUMBLEBEES (BOMBUS) AND FLOWERS ALONG AN ENVIRONMENTAL GRADIENT

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Johan Per Michael Svedin; [2022]
    Keywords : Arctic climate change; Bombus; Flower morphology; Plant-pollinator trait-matching;

    Abstract : Insect pollinators serve a critical role in maintaining plant biodiversity and are especially susceptible to changes within their environment. To study the possible effects of seasonal variation in temperature, as well as climatic temperature increase on the plant-pollinator community, the relationship between bumblebee and flowering plant traits along an elevational gradient, representing warming-induced changes in plant community, were examined.
