A team of researchers led by Melinda Smith at Yale and Travis Huxman at the University of Arizona report that, from desert to rainforest, during drought conditions, the maximum rain use efficiency (RUEmax), or effective productivity of plant growth per unit of precipitation converges to a common value.
During the late 1960s and early 1970s, the International Biological Program (IBP) began to study how water affects productivity in different ecosystems. It was not until this current group of scientists pooled long-term data in a workshop at the National Center for Ecological Analysis and Synthesis at University of California, Santa Barbara that the scope and similarity of productivity in all ecosystems was seen. Their study, published in the journal Nature, represents datasets from 14 ecosystems.
The RUEmax model predicts that when water is the most limiting resource there will be convergence in the production-precipitation ratio for all biomes. The previous, site model predicts there will be a difference in productivity and that sensitivity of different ecosystems is a function of the different forms of plant growth.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
