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.”

Scientists from the Theory Department of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science (CFEL) in Hamburg have shown through theoretical calculations and computer simulations that the force between electrons and lattice distortions in an atomically thin two-dimensional superconductor can be controlled with virtual photons. This could aid the development of new superconductors for energy-saving devices and many other technical applications.
