    University essay from SLU/Dept. of Ecology

    Author : Linnéa Bergström; [2020]
    Keywords : SLU; rödlistade kärlväxter; ekologi; skötselplan;

    Abstract : Den biologiska mångfalden är viktig ur flera perspektiv men nu är den hotad. Över 400 arter av kärlväxter är rödlistade och det drabbar även t.ex. humlor, bin och fjärilar. READ MORE

  3. 17. One Million-Point FFT

    University essay from Linköpings universitet/Datorteknik

    Author : Tobias Mellqvist; Hans Kanders; [2018]
    Keywords : Large FFT; FFT; Cooley–Tukey; SDF; Binary tree; FPGA; triangular matrix;

    Abstract : The goal of this thesis has been to implement a hardware architecture for FPGA that calculates the fast Fourier transform (FFT) of a signal using one million samples. The FFT has been designed using a single-delay feedback architecture withrotators and butterflies, including a three-stage rotator with one million rotation angles. READ MORE

  4. 18. Hur har dagfjärilsarternas utbredning förändrats sedan 1950-talet i Sverige?

  5. 19. The surrounding landscape’s impact on species density in species-rich grasslands

    University essay from Linköpings universitet/Biologi

    Author : Frida Eningsjö; [2017]
    Keywords : Landscape; plants; species density; species-rich grassland;

    Abstract : When the agricultural revolution took place, the biodiversity decreased and during the last century more than 90 % of the area of species-rich grasslands has been lost. Fragmentation has occurred with the area lost and insects, e.g. butterflies, suffer because of this. READ MORE

  6. 20. Traits and habitat specialization influence in future range shifts of butterflies in a warmer climate

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Jennie Frida Linn Gustafsson; [2017]
    Keywords : Climate change; Range shift; Trait; Pyrgus armoricanus; Butterfly;

    Abstract : Climate change is considered one of the greatest future threats against biodiversity. One predicted consequence of a global temperature increase is that biomes will move against the poles, which will force species to either adapt to an unsuitable habitat or follow their climatic range shift.
