  1. 1. The diversity of fungi in coniferous forests and mixed forests

    University essay from Karlstads universitet

    Author : Ida Asplund; [2023]
    Keywords : Forest type; coniferous forest; mixed forest; fungi; fungal diversity; mycorrhiza; saprotrothic fungi; parasites; parasitic fungi; Skogstyp; barrskog; blandskog; svampar; svampdiversitet; svampmångfald; mykorrhiza; saprotrofiska svampar; parasiter; parasitiska svampar;

    Abstract : The fungal domain has one of the highest biodiversities among eukaryotes and species within the domain fill important ecological roles, such as mutualistic mycorrhiza, decomposers, parasites and pathogens. The development of forest ecosystems and their related processes has not only been linked to fungal diversity but the composition and abundance of fungi benefits the abundance and diversity of other species as well.

  5. 4. Spatial Variation of THg and MeHg Stream Concentrations and Its Relation to TOC

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Maria Tranvik; [2017]
    Keywords : Mercury; organic matter; catchment characteristics; GIS; deforestation; Kvicksilver; organiskt material; avrinningsområdesfaktorer; GIS; skogsavverkning;

    Abstract : Mercury (Hg) which originates from global emissions to the atmosphere can deposit far away from the source. There is often a weak correlation between Hg deposition and concentrations in runoff, therefore catchment specific parameters might be of importance in controlling the amount of Hg ending up in watercourses and fish.

  6. 5. Elephant utilisation of and impact on a locally threatened habitat, coastal scarp forest, in South Africa

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

    Author : Matilda Apelqvist; [2016]
    Keywords : elephant impact; forest; scarp forest; herbivores; woody plants;

    Abstract : Elephants are known to have a big influence on the environment. Their browsing routine includes the breaking of stems and branches, toppling of trees, and bark stripping. This, in combination with other factors, can have negative effects on the vegetation. READ MORE
