  1. 1. Dietary fiber content and composition in heritage wheat

    Master-uppsats, SLU/Department of Molecular Sciences

    Författare :Lisa Andersson; [2022]
    Nyckelord :Heritage cereals; wheat; dietary fiber; fructan; Dacke; Dala Lantvete; Källunda; Ölandsvete;

    Sammanfattning : Wheat is the main food source in the world. A secured production has however been threatened by environmental changes in combination with the need of producing more food for a growing population. As a result, there has been an increasing interest in finding new crop varieties susceptible to abiotic stress. LÄS MER

  3. 2. Assessment of how environmental variables and vegetation structure influence peatland carbon fluxes

    Master-uppsats, Uppsala universitet/Växtekologi och evolution; Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Bernabé Ramírez; [2021]
    Nyckelord :;

    Sammanfattning : Boreal peatlands are important ecosystems from a carbon balance perspective because they are natural carbon sinks as a result of millennia of peat formation. However, due to climate change, these ecosystems are susceptible to changes in hydrology and temperature. LÄS MER

  4. 3. Context dependent variation in aggression and mating behaviour in the pygmy halfbeak (Dermogenys collettei) : a study of wild population

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Piotr Michalak; [2021]
    Nyckelord :aggression; animal behaviour; ecology; environment; group size; halfbeak; mating; OSR;

    Sammanfattning : To understand animal behaviour, it is important to consider the environment in which it occurs. The environment, consisting of both abiotic factors and social context, is usually highly variable and leads to variation in individual’s and group’s behaviour. LÄS MER

  5. 4. The effect of the interplay between fire frequency and grassland structure on tick abundances in the Hluhluwe-iMfolozi Park, South Africa

    Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Thilo Heinecke; [2020]
    Nyckelord :ticks; acari; pyrodiversity; grassland structure; fire ecology; fire frequency; grazing lawn;

    Sammanfattning : Fire in ecology is a very variable factor and its effects are best described as a complex feedback system with other biotic and abiotic factors. These feedback systems need to be understood to enable generalized conclusions about the influence of fire regimes. LÄS MER

  7. 5. Tea time for soils : decomposition experiments in Swedish long-term field trials

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Olle Åkesson; [2017]
    Nyckelord :Tea Bag Index; SOC; SOC dynamics; stabilization; decomposition;

    Sammanfattning : Abstract Soils represent a large carbon pool, with almost twice the amount contained in living plant biomass and the atmosphere combined. Consequently, soil has a significant impact on the global C cycle and it is suggested that soil organic C (SOC) sequestration is one of the most cost-effective alternatives to counteract climate change.
