Forest Management Type Influences Diversity and Community Composition of Soil Fungi across Temperate Forest Ecosystems
Fungal communities have been shown to be highly sensitive toward shifts in plant diversity and species composition in forest ecosystems. However, little is known about the impact of forest management on fungal diversity and community composition of geographically separated sites. This study examined the effects of four different forest management types on soil fungal communities. These forest m...
متن کاملForest Commons in Boreal Sweden – Influences on Forest Condition, Management and the Local Economy
Holmgren E. 2006. Forest Commons in Boreal Sweden – Influences on Forest Condition, Management and the Local Economy. This thesis examines the influences of Swedish forest commons on forest condition, management and the local economy. The approach is rationalistic, i.e. outcomes of forestry activities are assessed in relation to aims. According to the stated objectives, forest commons should se...
متن کاملPotential site productivity influences the rate of forest structural development.
Development and maintenance of structurally complex forests in landscapes formerly managed for timber production is an increasingly common management objective. It has been postulated that the rate of forest structural development increases with site productivity. We tested this hypothesis for Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) forests using a network of permanent study plots es...
متن کاملHeterogeneity influences spatial patterns and demographics in forest stands
1. The spatial pattern of tree species retains signatures of factors and processes such as dispersal, available resource patches for establishment, competition and demographics. Comparison of the spatial pattern of different size classes can thus help to reveal the importance and characteristics of the underlying processes. However, tree dynamics may be masked by large-scale heterogeneous site ...
متن کاملCicada Emergence in Southwestern Riparian Forest: Influences of Wildfire
Annually emerging cicadas are a numerically and ecologically dominant species in Southwestern riparian forests. Humans have altered disturbance regimes that structure these forests such that floods are less common and wildfires occur more frequently than was historically the case. Impacts of these changes on primary consumers such as riparian cicadas are unknown. Because cicadas are consumed by...
