Snow quality may affect the Canadian lynx’s ability to kill its prey, according to new research suggesting climate may be impacting one of the most fascinating ecological systems to intrigue biologists for decades. The University of Alberta’s Dr. Stan Boutin is part of a research team to study the relationship between the lynx and the snowshoe hare—an interaction that has grave implications on the dynamics of the whole boreal forest.
Boutin teamed up with other researchers from Canada, the United States and Norway—including evolutionary ecologist Nils Stenseth—to study the lynx-hare cycle, and how it related to the overall boreal forest community. Stenseth has previously argued that the 10-year cycle, which means a rise and fall of the hare population followed by a similar pattern of the lynx, differed according to regions of the country and those differences were tied to large-scale climatic patterns.
“The genetics of the lynx are quite different among these Canadian regions and we questioned whether there was some sort of barrier that might stop gene flow,” said Boutin, a biologist with the Faculty of Science. “We knew there was nothing physical between eastern and central regions, so we started to speculate that there may be something climate-related that would influence the lynx’s ability to prey on snow hares and their propensity to move between regions.”

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
