Forest management affects the quality and availability of roost sites for forest-dwelling bats, but information on roost selection beyond the scale of individual forest stands is limited. We evaluated effects of topography (elevation, slope, and proximity of roads and streams), forest habitat class, and landscape patch configuration on selection of summer diurnal roosts by 6 species of forest-d...

Forest management and the stand age play key roles in determining composition of soil biota, including nematodes. We analysed effect interaction between stands natural forest influenced by human activity on nematode communities, necessary for realistically assessing specific potentials soils, plant protection, management, land use management. Nematode communities were evaluated compared managed...

Finland Academic dissertation To be presented, with the permission of the Faculty of Agriculture and Forestry of the University of Helsinki, for public criticism in the Walter auditorium of the EE-building (Agnes Sjöbergin k. 2) on December 10 th 2004 at 12 o'clock noon. Abstract Boreal forests are dynamic, spatially heterogeneous ecosystems, and important reserves of biological diversity and t...

Multiversion STM systems allow a transaction to read old values of a recently updated object, after which the transaction may serialize before transactions that committed earlier in physical time. This ability to “commit in the past” is particularly appealing for long-running read-only transactions, which may otherwise starve in many STM systems, because short-running peers modify data out from...

• Climate warming and droughts impact growth in central European oak forests. Growth shifts old-growth managed Quercus petraea declining trees are identified. sensitivity forests is higher than Past use legacies stand structure drive sensitivity. Managed more vulnerable under forecasted climate-warming. warming-related drought could become a major driver of large-scale forest dieback. However, ...

I examined the interactions of key components of a hunting system of Sitka black-tailed deer (Odocoileus hemionus sitkensis) on Prince of Wales Island, Alaska to address concerns of subsistence hunters and to provide a new tool to more effectively monitor deer populations. To address hunter concerns, I documented local knowledge and perceptions of changes in harvest opportunities of deer over t...

Soil health conceptualized as a measurable ecosystem property provides powerful tool for monitoring progress in restoration projects or implementation of best management practices to improve degraded lands and promote sustainable agroecosystems. We surveyed soils collected from range land uses (i.e., protected native non-native forest, managed pasture, unmanaged previously intensive agricultura...

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...

Large uncertainties characterize forest development under global climate change. Although recent studies have found widespread increased tree mortality, the patterns and processes associated with tree death remain poorly understood, thus restricting accurate mortality predictions. Yet, projections of future forest dynamics depend critically on robust mortality models, preferably based on empiri...
