  1. 1. 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. How Does Intraspecific Trait Variation Influence the Climate Niche Breadth of Tropical Tree Species?

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Helene Hansen; [2022]
    Keywords : intraspecific variation; niche breadth; plants;

    Abstract : With the contribution of intraspecific trait variation (ITV) to ecological processes being increasingly appreciated, its role in defining niche characteristics arises as a topic of interest. I hypothesised that species with a high magnitude of ITV would occupy a larger climate niche breadth than species with little ITV.

  5. 4. With neighbours like these : what influences the size of Scandinavian wolf territories

    University essay from SLU/Dept. of Ecology

    Author : Jakob Ahlberg; [2022]
    Keywords : wolves; home-range size; intraspecific competition;

    Abstract : The home-range of an animal and what factors influence it’s size and appearance is vital information when it comes to understanding and protecting a species. One of these factors can be intraspecific competition over resources, especially amongst territorial species like large carnivores. READ MORE

  6. 5. Brain morphology and behavioural variation in relation to habitat and predation risk in minnows (Phoxinus phoxinus)

    University essay from Uppsala universitet/Limnologi; Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Marina Gallego González; [2022]
    Keywords : brain size; Ecology; environmental complexity; European minnow; fish; geometric morphometrics; morphological divergence; phenotypic plasticity; schooling.;

    Abstract : So far, research on inter- and intraspecific teleost brain plasticity across different freshwater environments has been widely conducted. However, insights of brain morphological variation on social and predator avoidance behaviours are lacking. READ MORE
