INTRODUCTION The effect of logging on spotted owls (Strix occidentalis) and their habitat has been one of the most pressing wildlife conservation questions facing western forest managers for the past 30 years. Two subspecies, the northern and Mexican spotted owls (S. o. caurina and S. o. lucida, respectively), have been listed as threatened, in part, based on the loss of habitat due to logging ...
Green-tree retention is a forest management method in which some living trees are left on a logged area. The aim is to offer 'lifeboats' to support species immediately after logging and to provide microhabitats during and after forest re-establishment. Several studies have shown immediate decline in bryophyte diversity after retention logging and thus questioned the effectiveness of this method...
Forest fragmentation and selective logging are two main drivers of global environmental change and modify biodiversity and environmental conditions in many tropical forests. The consequences of these changes for the functioning of tropical forest ecosystems have rarely been explored in a comprehensive approach. In a Kenyan rainforest, we studied six animal-mediated ecosystem processes and recor...
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...
The Director's Workshop is an iconic interface for the logging of multimedia information in domain-independent, multimedia archives. The interface makes use of a temporally indexed, semantically structured representation of the content for multimedia information. Descriptive icons are quickly selected by cascading through icon hierarchies, and then organized into palettes for use in the logging...
This paper investigates the problem of rollback recovery in distributed shared memory (DSM) systems. We propose a new log-based recovery approach, which can tolerate multiple node failures. The recovery approach employs an independent checkpointing technique and a new logging scheme. The independent checkpointing technique periodically interrupts the execution of a node to save the node’s state...
Trustworthy system logs and application logs are crucial for digital forensics. Researchers have proposed different security mechanisms to ensure the integrity and confidentiality of logs. However, applying current secure logging schemes on heterogeneous formats of logs is tedious. Here, we propose Forensics Aware Language (FAL), a domain-specific language (DSL) through which we can apply a sec...
This paper describes a set of tools that allows a developer to instrument a C/C++ program to log data at run-time and then analyze that data to verify correct behavior. The logging tools provide the developer with a means to log a variety of di erent data to a variety of di erent outputs. They also allow for synchronized logging of data from distributed programs. One logging output option is an...
