Fifty-nine stems of Tetrastichia bupatides, numerous frond segments, and roots from Oxroad Bay, Scotland, have recently been analyzed. They reveal that many characters originally used to describe this species exhibit a wider range of variation than previously suspected. These data suggest that ribs of the protostele are most commonly four...
Despite the importance of fire for maintaining the health of many ecosystems, the social and economic costs of wildfires have risen sharply in recent years. Across the western United States, historical land and fire management practices combined with climate change and modern human development pressures, are contributing to increased wildfire...

Changes in the structure of the U.S. agricultural
industry since World War II have transformed it into a
highly productive component of the domestic economy. But
these changes have not occurred without indirect costs. For
example, the reliance on agricultural chemicals has produced
environmental effects causing growing concern. In addition,...
Commercial thinning operations can result in damage to residual stems. A literature review revealed that little was known about the effects of residual logging wounds with regard to rotation-age commercial conifers, particularly Douglas-fir. An experiment to examine fungal colonization of Douglas-fir following logging damage showed that while damage was significant...

Understanding how forest roads interact with hillslope hydrology by intercepting and/or rerouting storm runoff will better enable land managers to
reduce erosion related to forest roads. Watershed scale knowledge of how culvert runoff response varies across the landscape would provide valuable
information to those individuals designing and maintaining forest road...
The impact of forest roads on the hydrology of forested watersheds has long been studied. While forest roads have been reported to alter storm runoff at the road segment scale, the potential for changes to be detectable at the small watershed scale has been debated. The purpose of this study...
Climate change, wildfire, timber harvest, and land conversion alter the availability of downed wood in forests of the western United States. Numerous taxa rely on downed wood for temperature and humidity refugia, and downed wood may play a key role in enabling the persistence of climate-sensitive, low-vagility species like terrestrial...

Stream restorations that increase geomorphic stability can improve habitat quality, which should benefit selected species and local aquatic ecosystems. This assumption is often used to define primary restoration goals; yet, biological responses to restoration are rarely monitored or evaluated methodically. Macroinvertebrate communities were inventoried at 6 study reaches within 5...
