Government agencies are considering scores of applications to develop utility-scale solar power installations in the desert Southwest of the United States, but too little is known to judge their likely effects on wildlife, according to an article published in the December 2011 issue of BioScience.
Although solar power is often seen as a "green" energy technology, available information suggests a worrisome range of possible impacts. These concern wildlife biologists because the region is a hotspot of biodiversity and includes many endangered or protected species, notably Agassiz's desert tortoise. It and another tortoise, Morafka's, dig burrows that shelter many other organisms.
The article, by Jeffrey E. Lovich and Joshua R. Ennen of the US Geological Survey's Southwest Biological Science Center, notes that solar energy facilities are poised for rapid development and could cover hundreds of thousands of hectares. Assessments of their effects should count both onsite and offsite effects and include construction and decommissioning as well as the operational phase, the authors point out. Yet there are to date almost no peer-reviewed studies on the impacts of solar installations specifically.
The authors' initial attempt to catalogue the foreseeable effects draws attention to habitat fragmentation caused by roads and power lines, which could restrict gene flow, as well as the production of large amounts of dust through ground-disturbance. Solar plants are also expected to release pollutants such as dust suppressants, rust suppressants, and antifreeze, both in routine operation as well as through spills. They will predictably generate heat, electromagnetic fields, noise, polarized light, and possibly ignite fires. Evaporative ponds, which concentrate toxins, may be used and are a recognized hazard to wildlife. Because wet-cooled turbines need to be supplied with large amounts of water, developers are leaning toward using dry-cooled turbines, but these have a larger "footprint" than wet-cooled ones.
The dearth of reliable information indicates an urgent need for careful, controlled, pre- and post-construction studies of the effects of solar power plants in the Southwest, Lovich and Ennen argue. Such studies could attempt to determine information useful for optimally siting the plants, such as whether damage is minimized if they are concentrated in a few places or dispersed, as well as suggest preferred locations and mitigation possibilities.
After noon EDT on 9 December and for the remainder of the month, the full text of the article will be available for free download through the copy of this Press Release available at www.aibs.org/bioscience-press-releases/.
BioScience, published monthly, is the journal of the American Institute of Biological Sciences (AIBS). BioScience publishes commentary and peer-reviewed articles covering a wide range of biological fields, with a focus on "Organisms from Molecules to the Environment." The journal has been published since 1964. AIBS is an umbrella organization for professional scientific societies and organizations that are involved with biology. It represents nearly 160 member societies and organizations.

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...
