Windstorms, bark beetle outbreaks and fires are important natural disturbances in coniferous forests worldwide. Wind-thrown trees promote biodiversity and restoration within production forests, but also cause large economic losses due to bark beetle infestation and accelerated fungal decomposition. Such damaged trees are often removed by salvage logging, which leads to decreased biodiversity an...

A new type of logs, the command log, is being employed to replace the traditional data log (e.g., ARIES log) in the inmemory databases. Instead of recording how the tuples are updated, a command log only tracks the transactions being executed, thereby effectively reducing the size of the log and improving the performance. Command logging on the other hand increases the cost of recovery, because...

Conducting psychophysiological experiments that measure how players experience digital games not only allows investigating the effects digital games have on players, it also gives game developers a tool to validate game design. In order to develop digital games rapidly that can be used as stimuli in psychophysiological experiments, a coherent and flexible development environment is required. A ...

Sixty-four different logging scenarios for an initially undisturbed forest stand at Deramakot (Malaysia) were simulated with rain forest growth model FORMIND. The scenarios differ regarding the logging cycle, logging method, cutting limit and logging intensities. We characterise the impacts with four criteria describing the yield, canopy opening and changes in species composition. Multicriteria...

We summarize the documented and potential impacts of salvage logging--a form of logging that removes trees and other biological material from sites after natural disturbance. Such operations may reduce or eliminate biological legacies, modify rare postdisturbance habitats, influence populations, alter community composition, impair natural vegetation recovery, facilitate the colonization of inva...
