  2. 2. Biodiversity and habitat conditions in reaches with high flow velocity along gradients in hydrological and geomorphological alteration : A study of six rivers in Sweden

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Anders Aalto; [2021]
    Nyckelord :Hydrology; Geomorphology; Biological variables; Human alteration;

    Sammanfattning : The vast majority of rivers in the developed world are affected by human alteration, which in turn negatively affects the species that rely on these highly diverse and species rich areas to survive. Homogenization of previously heterogenic areas due to a change in water discharge and the substrate availability in the rivers is often regarded as the main reason for the loss of species richness in rivers and the riparian zone.

    Sammanfattning : The ongoing global climate change with its rising trends in global temperature, can be linked to the increasing frequency, intensity, duration, and extent of extreme weather fluctuation. Urban heat waves, in combination with urbanization processes which replace natural landscapes with impervious surfaces, are causing the development and manifestation of urban heat islands (UHI) in cities.
