The global decline of amphibians has received a great deal of attention because amphibians are thought to be indicator species, or canaries in a coal mine that provide an early warning of environmental degradation. The topic has drawn considerable scientific attention because there is no obvious, simple cause. Researchers are pursuing a handful of explanations for worldwide losses of amphibian populations that are likely to affect all species. Thus, understanding the complexity of the amphibian decline case may provide insight as to how other species, including humans, may be affected by changes in the environment.
In a forthcoming special issue of Diversity and Distributions, several of the leading hypotheses for amphibian declines are addressed in a comprehensive volume for the first time in a primary scientific journal. In an introductory paper, Dr. James Collins (Arizona State University) and Dr. Andrew Storfer (Washington State University) establish a framework for studying the leading explanations. Leaders in the field then provide comprehensive reviews of the effects of: introduced non-native species (Lee Kats and Ryan Ferrer, Pepperdine University), increased ultraviolet radiation and chemical contaminants (Andrew Blaustein, Oregon State University, and others), global warming (Cynthia Carey and Michael Alexander, University of Colorado), and emerging infectious diseases (Peter Daszak, Consortium for Conservation Medicine, and others). Finally, future directions in amphibian conservation research are discussed in a summary article by the guest editor of the volume, Dr. Storfer.
The worldwide decline of amphibians is part of a general biodiversity crisis. Amphibians are clearly not canaries, but they are likely sending us the same message - our environment is changing and we are in danger if we don’t pay attention!

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
