Climate change's effects on temperate rain forests surprisingly complex

22.01.2013
Science-based strategies help managers to adapt to general warming trend

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.

The Pacific Northwest Research Station—headquartered in Portland, Oregon—generates and communicates scientific knowledge that helps people make informed choices about natural resources and the environment. The station has 11 laboratories and centers located in Alaska, Oregon, and Washington and about 390 employees. Learn more online at http://www.fs.fed.us/pnw.

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
