We bring fitness trackers that tell you how many steps you’ve taken and how many calories you’ve burned.But Cory Williams of the University of Northern Arizona and colleagues tied a group of arctic yellow rats with devices like “fitness trackers,” documenting the behaviour of gender-specific arctic rats in different seasons.
One of the few ground squirrels hibernate animal as the Arctic tundra, they will be in the underground lair sleep all through the winter months. While hibernating in a year removed, they will often run on the ground. The male rats than in female rats more late hibernation, earlier recovery. Every spring, wake up the male rats in underground nests will eat food for gonadal growth, then to the ground with other males fight to establish their own territory. For the Arctics, “on the ground” is a prudent choice. Climb the ground means more food, but left the nest – bunker natural – often means greater risk. Williams and his colleagues are curious about how they make such choices and how they allocate time on the ground and underground.And whether there are different ways of making decisions in different genders.
The way to study this problem is to attach a “fitness tracker” to them.Well, to be precise, it’s the smart collar, which incorporates sensors that sense light to record the amount of time the arctic yellow rat experiences light every day.When the arctic rat moves on the ground, the light sensor accepts the surrounding light and is therefore “light”.And when they get to When dark underground, the sensor will switch to “no light” state.So for scientists, just analyzing the periods of “light” and “no light” can mimic where the arctic yellow rat works.
Their practice of giving squirrels a set of “fitness trackers” will also provide a reference for future researchers-it is more flexible and provides more information on different directions than the traditional field survey method with fixed cameras.They may be useful tools for ecological research.
