  1. 1. Constructing a food web from inventory data in a boreal forest-dominated national park in south-eastern Sweden

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Philip Kjellström; [2023]
    Nyckelord :ecological network; food web; boreal forest food web; national park food web; interspecific competition; swedish forest; construction food web;

    Sammanfattning : A food web was constructed for a boreal-forest dominated national park in south-eastern Sweden, called Tyresta national park and its surrounding nature reserve. Due to increasing threats to mammalian species and their critical role in the food web mammals were used as the outset of the food web, and from there branching out to taxa trophically interacting with mammals directly and indirectly.

  3. 2. Challenges in a changing climate : The effect of temperature variation on growth and competition in damselflies

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Kim Lea Holzmann; [2022]
    Nyckelord :ecology; climate change; thermal variation; competition; cannibalism; damselfly;

    Sammanfattning : Climate change is affecting biodiversity on multiple levels all over the world. Concomitant with a higher mean temperature, an increased amplitude of temperature variation is predicted. LÄS MER

  4. 3. Effects of diversified cropping on arthropod communities

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Eira Eksvärd; [2022]
    Nyckelord :carabids; spiders; traits; organic amendments; ley legacy effects;

    Sammanfattning : Även intensiva moderna jordbruk är beroende av ekosystemtjänster som organismer bidrar med såsom biologisk bekämpning av skadedjur. Effekten av biodiversitet på ekosystemprocesser förklaras inte i tillräcklig grad av taxonomisk mångfald, utan beror snarare på mångfalden av funktionella egenskaper bland arterna. LÄS MER

  5. 4. Biological control of thrips with Neoseiulus cucumeris and Orius majusculus in strawberry tunnels

    Master-uppsats, SLU/Dept. of Plant Breeding (from 130101)

    Författare :Robin Kalenius; [2016]
    Nyckelord :thrips; Neoseiulus cucumeris; Orius majusculus; strawberry; tunnels; resistance; IPM; IGP;

    Sammanfattning : Several cases of thrips resistance to pesticides have been observed due to heavy usage of insecticides during the seventies-eighties. Thrips complex enzyme metabolic detoxification system and fast reproduction has lead to a classification of major pest in strawberry production. LÄS MER

  7. 5. Effect of temporal increases in prey fish abundance on individual growth rates of coastal piscivores

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

    Författare :Johan Penner; [2016]
    Nyckelord :Three-spined stickleback; Perch; Growth; Intraguild Predation; Ontogeny; Baltic Sea.;

    Sammanfattning : Commercial fishing in the Baltic Sea has led to decrease in abundance of large predatory fish and as a result the predation pressure on smaller fish species has been reduced. Three-spined stickleback (Gasterosteus aculeatus) is among the species that have benefited from reduced predation pressure. LÄS MER
