Fungal Interactions with Human Activities

All of the above roles of fungi in natural ecosystems are increasingly influenced by human activity. In Chap. 6 we will examine some specific interactions between anthropogenic impacts and the function of fungi, together with how fungi may be used to mitigate some of the effects of human-induced disturbance and pollution. Fungi are negatively influenced by acidifying pollutants, such as sulfur dioxide, which damages the physiological capacity of fungi (Arnolds, 1991 Dighton and Jansen, 1991...

Edaphic Relations Biodiversity and Function

Evidence to demonstrate the differences in activity among ectomycorrhizal fungal species is plentiful within the literature. In many papers that compare the plant response to a variety of ectomycorrhizal associates, there are differences in plant response (Villeneuve et al., 1991a). Most of these studies are conducted in the laboratory or greenhouse, however, in somewhat artificial conditions. Field observation of the advantage of inoculation of tree seedlings with a variety of mycorrhizal...

Interplant Linkages Competition Vs Synergism

In the 1960s Bjorkman 1960 discovered that by injecting radioactive carbon into the stem of a pine tree he could detect the isotope in an adjacent Monotropa plant. Monotropa is an achlorophyllous plant that was thought to be parasitic on the roots of trees, as it could not manufacture its own carbohydrates by photosynthesis. He also noted that there were ectomycorrhizal associations of the roots of both the Monotropa plant and the tree. He therefore suggested that there could be a carbohydrate...
