Longer, warmer growing seasons associated with a changing climate are altering growing conditions in temperate rain forests, but not all plant species will be negatively affected, according to research conducted by the U.S. Forest Service's Pacific Northwest Research Station.
Research featured in the January 2013 issue of Science Findings—a monthly publication of the station—reveals a complex range of forest plant responses to a warming climate.
"Although the overall potential for growth increases as the climate warms, we found that plant species differ in their ability to adapt to these changing conditions," said Tara Barrett, a research forester with the station who led the study.
Barrett and her colleagues explored trends in forest composition in southeastern and south-central Alaska, home to the bulk of the world's temperate rain forests. The researchers found an uptick in growth in higher elevations of the region over the 13-year period, with an almost 8-percent increase in live-tree biomass, a measure of tree growth. Individual species within the rain forest, however, differed—western redcedar biomass increased by four percent, while shore pine declined by almost five percent.
As forest managers consider climate impacts like these in the management of their forests, scientists, including Barrett and research biologist David L. Peterson, are communicating climate change science within the agency, helping managers—in Alaska and beyond—to meet this challenge.
In another research effort, featured in the December 2012 issue of Science Findings, Peterson summarized the scientific basis for climate change adaptation. He and his colleagues across the country have conducted case studies that revealed the critical role of science-management partnerships in adaptation planning and have produced a climate change guidebook and Web portal for climate science information.
"The main objective is to get science in the hands of managers so that they have the basic information but also have access to the documentation they need to do their jobs," said Peterson.

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...
