The ranchland near the southwestern Alberta town of Pincher Creek is a hot zone for grizzly bear encounters according to a new study conducted by researchers at the University of Alberta.
The research, led by former U of A graduate student Joe Northrup, mapped the locations of 303 grizzly bear encounters over the last 10 years. There were no human fatalities despite the fact that the vast majority of the encounters happened on private ranch land.
The researchers had strict guidelines for measuring a grizzly bear encounter. "We didn't count sightings of bears by back-country hikers," said Northrup. "We only documented encounters where there the bear approached people and there was a potential threat to the person or their property."
The researchers also surveyed the sites of bear encounters on or near private land and came up with a property description with a high potential for trouble in the Pincher Creek area. "Our research showed that a ranch house on a quarter-section that is lined with trees and close to a river bed has a high potential for problems," said Northrup. He added that river beds coming down from the mountains are a popular transportation route for bears.By far the biggest attractant for grizzly bears in the ranchland area is dead cattle and Northrup says it's a complicated hazard. "Ranchers need permits to remove dead cattle because of health restrictions to control Mad Cow disease," said Northrup, adding permits can be time consuming and the researchers found another problem. "The land fill has to be able to accept dead cattle and the Pincher Creek dump doesn't have that kind of permit," said Northrup.
The research by Northrup, U of A biology professor Mark Boyce and G.B. Stenhouse of the Foothills Research Institute was published in the journal, Animal Conservation.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
