  1. 1. Modelling the effects of substituting pollinators in decline

    University essay from Lunds universitet/Matematik LTH

    Author : Axel Eriksson; [2023]
    Keywords : pollinators; plants; mutualism; competition; equilibrium populations; Mathematics and Statistics;

    Abstract : While pollination is essential for many plant species and ecosystem functions, pollinator populations worldwide are declining. This decline is largely due to abiotic changes in the environment: climate change and other anthropogenic impacts, such as pesticides and land use change. READ MORE

  3. 2. Multi Agent Reinforcement Learning for Game Theory : Financial Graphs

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

    Author : Bryan Yu; [2021]
    Keywords : Multi-Agent Reinforcement Learning; Reinforcement Learning; Game Theory; Financial Networks; Financial Graphs; Machine Learning; Financial Graphs; Computational Economics; Multi-Agent Reinforcement Learning; Reinforcement Learning; Game Theory; Financial Networks; Financial Graphs; Machine Learning; Financial Graphs; Computational Economics;

    Abstract : We present the rich research potential at the union of multi agent reinforcement learning (MARL), game theory, and financial graphs. We demonstrate how multiple game theoretic scenarios arise in three node financial graphs with minor modifications. We highlight six scenarios used in this study. READ MORE

  4. 3. Golden Eagle (Aquila chrysaetos) genomics across Scandinavia : population structure and effects of marker selection

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Måns Näsman; [2018]
    Keywords : aquila chrysaetos; rad-seq; marker selection; hardy weinberg; population structure;

    Abstract : Rapid development in DNA-sequencing has led to increased use of single nucleotide polymorphisms (SNPs) as molecular markers in wildlife genetic studies. RAD-sequenced SNP-markers can produce large datasets that are successfully used in studies on animal population structure. READ MORE

  6. 5. Genetic analysis of the otter population (Lutra lutra) in Kristianstad’s Vattenrike Biosphere Reserve, Sweden

    University essay from Högskolan Kristianstad/Sektionen för lärande och miljö

    Author : Sanne Bergman; [2017]

    Abstract : During the past century the Swedish otter (Lutra lutra) population showed a rapid decline in abundance and genetic diversity. Among the most affected areas was the southern province of Skåne. After prohibiting hunting of otters and banning harmful pollutants like PCB, Swedish populations slowly recovered. READ MORE
