Voles are pedestrians, too, and need just as much help crossing the road as the big animals, says new research from the University of Alberta.
"There has been a mindset that bigger is better--driven by research on large mammals and especially bears," said Dr. Colleen Cassady St. Clair, from the Department of Biological Sciences. "This research shows that small affordable culverts, which can be placed with high frequencies while building roads, are very effective conduits for small mammals."
The study, recently published in the Journal of Applied Ecology, investigated how small mammals--meadow voles, red-backed voles and deer mice--used crossing structures built across the Trans-Canada Highway. Cassady St. Clair and graduate student Wayne McDonald looked at size, vegetative cover at the entrances of the structures and the distance from home ranges to determine what kind of structures the animals would use the most.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
