Plant-specific soil-borne diseases contribute to succession in foredune vegetation

Article Abstract:

Soil-carried pathogens that attack particular plants help to bring about the succession of plant species that characterizes European coastal foredune ecology. This succession involves the initial dominance of Marram grass or Ammophila arenaria, which then gives way to Festuca rubra, which is followed by other plants in a predictable order. Each plant becomes dominant because it is immune to the pathogens that diminished the previous dominant plant.

Evidence that decomposition rates of organic carbon in mineral soil do not vary with temperature

Article Abstract:

The turnover of forest mineral soil in forest soils seems to be very constant on a global scale. It does not vary according to differences in mean annual temperature.
