Mitochondria provide energy for biological cells to function, but this process is also a source of oxygen radicals that are capable of damaging nearby proteins. Mitochondrial protein damage can eventually lead to cell death, especially in the case of heart cells, where mitochondria are present in the highest concentrations. As...
Oomycetes form a deep lineage of eukaryotic organisms that includes a large number of plant pathogens which threaten natural and managed ecosystems. We undertook a survey to query the community for their ranking of plant-pathogenic oomycete species based on scientific and economic importance. In total, we received 263 votes from...
The U.S. Forest Service has published the final version of regulations on the surface use of National Forest lands under the amended mining laws of 1872. These regulations became effective September 1, 1974. Although the Mining Law of 1872 is still largely intact, the new regulations place some requirements in...
No-till pasture renovation can increase the quality and forage yield of underproductive pastures. Decreased erosion, lower costs, and less lost grazing time are advantages of no-till renovation compared to conventional renovation. Unwanted vegetation is first controlled with herbicides to decrease competition for introduced orchardgrass. Two field trials were conducted using...
Wildfire risk in temperate forests has become a nearly intractable problem that can be characterized as a socioecological “pathology”: that is, a set of complex and problematic interactions among social and ecological systems across multiple spatial and temporal scales. Assessments of wildfire risk could benefit from recognizing and accounting for...
A laboratory method for evaluating wood preservatives should provide in a comparatively short time an integrated measure of the relative permanence and fungus-inhibiting capacity of a product. There is as yet no generally acceptable laboratory method of this type. Systematic service records serve to bolster the reputation of established preservatives....
