  1. 1. FRÅN UTSÄTTNING AV ÖRINGROM TILL ÅRSYNGEL : EFFEKTER AV UTSÄTTNINGSMETODIK OCH INTRASPECIFIKA INTERAKTIONER

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

    Författare :David Rode; [2023]
    Nyckelord :;

    Sammanfattning : Egg stocking is a common method of re-establishing brown trout (Salmo trutta) populations, while the outcomes have been shown to give different results depending on variations in methods and locations. More recently, the dispersal of yearlings has been studied, but research on intraspecific interactions after egg stocking and the optimal number of eggs stocked are less studied. LÄS MER

  2. 2. Beware of your neighbour : the effects of intraspecific interactions and CO2-level on the plant growth of two Barley cultivars

    Kandidat-uppsats, SLU/Dept. of Plant Protection Biology

    Författare :Nadja Nyberg; [2023]
    Nyckelord :Barley; Salome; Fairytale; cultivar mixture; pure stand; intraspecific competition; plant-plant interactions; competitive ability; elevated CO2;

    Sammanfattning : Plants have evolved several ways to sense what is going on around them. They can detect possible competitors by picking up on airborne Volatile Compounds emitted from neighbouring plants. The cues can induce growth responses that enhances the competitive ability of the receiver. LÄS MER

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

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Jakob Ahlberg; [2022]
    Nyckelord :wolves; home-range size; intraspecific competition;

    Sammanfattning : 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. LÄS MER

  4. 4. The effect of temperature on the interaction between larvae of a native and a range expanding dragonfly species

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Sanne Everling; [2021]
    Nyckelord :Climate change; temperature; native; invasive; competition; behaviour; Odonata;

    Sammanfattning : Climate change might affect the distribution of species; therefore, it is important to anticipate the imminent impact of climate change. Even though climate responses have the potential to affect species interactions, most models on the effect of climate change on species distribution assume that species respond to climate individually.

  5. 5. Multifaceted effects of competition and plant-soil feedbacks on Achillea millefolium grown in soil from a riparian meadow : Emil Karlsson - Umeå University - Thesis project - 60 hp

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

    Författare :Emil Karlsson; [2021]
    Nyckelord :Plant; Competition; Plant soil feedback; Yarrow; Achillea millefolium; Centaurea cyanus; Soil; pH; Nitrate; Ammonium; Nitrogen; Soil texture; Light; Sweden; Height; Biomass; Field; Growth chamber; Greenhouse; Ecology; Relative fitness; Stabilizing niche; Konkurrens; Jordmån; Kärlväxter; Röllika; Blåklint;

    Sammanfattning : Competition between plant individuals and how plants alter soil properties are key processes which drive changes in plant communities over time. Estimating the relative importance of these processes and how they affect plant growth in different ecological contexts and communities is an active area of research. LÄS MER
