Under a changing climate, patterns of forest disturbance are expected to change, but how will forest diseases respond? A summary of scientific information that addresses this question is now available on the Internet at http://www.fs.fed.us/psw/topics/insect_disease/.
The site includes a searchable bibliography. The summary, titled "Review of Literature on Climate Change and Forest Diseases of Western North America" is sponsored by the USDA Forest Service.
Currently the forested area annually infected by insects and pathogens in the United States is approximately 45 times the area affected by fire, with an economic impact almost five times as great. The literature review shows climate change generally will lead to reductions in tree health and will improve conditions for some highly damaging pathogens.
Citations and summaries for over 1000 records of journal articles and working papers on forest pathogens and climate are retrievable by author, topic, species, or geographic area. Search the on-line annotated bibliography to discover these and other examples:Sudden Oak Death is driven by extreme weather events where heavy rains during warm periods create optimal conditions for Phytophthora to reproduce and infect oaks.
An outbreak of Red Band Needle Blight on lodgepole pine is associated with increased summer precipitation that was beyond the range of previously recorded weather patterns.
The Alaska-yellow-cedar decline mystery was solved by noticing that areas with abundant dead yellow-cedar experienced temperatures that were relatively lower in the winter with reduced snowpack. The mortality is caused by earlier snow melt, exposing the yellow cedar's shallow roots to colder temperatures resulting in freeze injury and death.
This collaborative effort is the first of its kind to synthesize the information known about the interactions of climate change, pathogens and forests in a systematic and useful way for land managers addressing climate change.
This work is part of a larger Forest Service effort to incorporate climate change into its research, land management and day-to-day business operations. Learn more about the Forest Service Strategic Framework for Responding to Climate Change at http://www.fs.fed.us/climatechange/.

New 3-D model predicts best planting practices for farmers

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
