Scientists and scientists often need to see individual animals in the forest to help answer questions about population size, eating habits and more. But there’s a problem: Many of the marks they use, like symbols with colors or numbers on them, are clearly visible in the sun – it’s hard to learn. Killing nocturnal animals.

Now, researchers with post-doctoral colleague Yasmine Majchrzak have found a simple and effective way to solve this problem: a bar code model using hot rods attached to antennae or collars used in field research.

“We’re capturing people because we’re looking at life and nature, so we thought, what if we could put some kind of base on the collars and antennae and try to See them that way? ” where Majchrzak.

Non -invasive, non -invasive use of the same type of ducts can be reduced to cover cords or wires to prevent wear and tear. It’s a real reminder that when photographs are printed with inflated photo frames, that’s what researchers usually set up in the field.

“The biggest limitation with current methods is that you can’t really see numbers or colors or something like that at night,” Majchrzak said. “The fact that you can have a mindset that’s easy to see is a huge benefit.”

Simply incorporating an integrated feature into the collars and antennae is now the ideal model for a wide range of sizes and animal species, Majchrzak explains. .

“We were able to use it in a small way, the snowshoe hare, it’s not a place where people can often get personal information.”

With snowshoe hares, Majchrzak and his colleagues were able to try out a new breed of Canadian lynx – two good ways to try them because they are black at night, he explains.

The track can be used to monitor the number of animals that cannot be captured.

Majchrzak said the new method could be used to answer ecological questions, such as how often a mother visits a nest to watch her young or animals spend a lot of time. ana.

“I hope this paper will be available to other researchers who are looking for a way to identify people at night for their own research, and maybe it will help them.”

Colleagues include Stan Boutin, a physician in the Department of Biological Sciences, and Banting postdoctoral fellow Michael Peers.
