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/.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
