  1. 1. Plant-soil feedbacks in boreal tree species

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Kailey Tentis; [2023]
    Nyckelord :plant-soil feedback; plant economic spectrum; biotic feedback; abiotic feedback; sterilization-inoculation experiment; conspecifics and heterospecifics;

    Sammanfattning : Plant-soil feedback (PSF) is important for understanding how plants influence the composition and abundance of soil biota and nutrients and how this affects plant growth. The plant economic spectrum (PES) also plays a role. LÄS MER

  3. 2. 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

  4. 3. Biotiska faktorers inverkan på markstrukturen

    Kandidat-uppsats, SLU/Dept. of Soil and Environment

    Författare :Sanna Krüger Persson; [2017]
    Nyckelord :markstruktur; näringsväv; feedback; markorganismer; aggregat;

    Sammanfattning : Soil structure is a key factor in the functioning of soil, including its ability to support root growth. Soil structure influences the circulation of nutrients and affects the gas exchange, and acts as habitat for the soil organisms. LÄS MER
