Is an ultraviolet flashlight part of your camping kit? If not, you may want to get one. Scientists in Wisconsin have just discovered that flying squirrels, including two specimens from B.C., are vividly fluorescent under UV light.

Skeptical? At first, so were the colleagues of Wisconsin-based biologist Jonathan Martin, who stumbled upon the splendorous squirrels in his own backyard.

Martin told Black Press Media it all started when the world91裸聊视频檚 first fluorescent frogs were discovered in the tropics in 2017.

Intent on finding out if the frogs in his woodsy backyard also fluoresce (they don91裸聊视频檛), he purchased a UV flashlight.

Martin was outside with the flashlight, poking around in some of the surrounding plant life, when he heard activity at his bird feeder.

91裸聊视频淲e have quite a few flying squirrels that come to the bird feeder and I just happened to be out there, heard it and didn91裸聊视频檛 even think that it was a UV light in my hand,91裸聊视频� said Martin, who instinctively turned toward the squirrels. 91裸聊视频淚 was like, 91裸聊视频楬oly smokes!91裸聊视频�91裸聊视频�

Under the UV light, the flying squirrels were fluorescing pink.

91裸聊视频淭he pictures don91裸聊视频檛 do it justice,91裸聊视频� said Martin. 91裸聊视频淚t91裸聊视频檚 bright pink. It91裸聊视频檚 neon pink.91裸聊视频�

Being a professor of forestry at Northland College in Wisconsin, or a 91裸聊视频渢ree guy91裸聊视频� as he says, Martin was met with some skepticism when he told his mammal-specialized colleagues about the fuchsia fur.

But at Martin91裸聊视频檚 request, Northland natural resources professor Erik Olson took a UV flashlight along with him on a mammal trapping trip. Olson saw the ros茅 rodents, then so did Northland91裸聊视频檚 small animal expert Paula Spaeth Anich, and soon the professors were collaborating with Allison Kohler, an undergraduate student at Northland at the time.

Did you know flying squirrels GLOW PINK in the dark? They fluoresce under UV! My colleague made the startling discovery while standing in his backyard (in pajamas) with a UV flashlight!

Kohler, who is the lead author of they published in the Journal of Mammalogy on Jan. 23, went to museums to test flying squirrel specimens for the fluorescence.

91裸聊视频淲e saw it on virtually every specimen, so then we knew it was really something special,91裸聊视频� Martin said.

Martin was able to confirm there were at least two Canadian squirrels of the Glaucomys sabrinus (northern flying squirrel) variety included in the database of about 130 specimens.

Based on the longitude and latitude listed in the database, two of the Canadian specimens originated from B.C.91裸聊视频檚 Lower Mainland: One from Hope and one from Abbotsford.

Even more interesting are the years that some of the specimens, including the Canadian ones, were collected.

91裸聊视频淎ccording to the database, one of the specimens from B.C. was collected in 1894,91裸聊视频� said Martin.

While the scientists who made the discovery think the fluorescence may be caused by some sort of protein in their fur, further research is needed to know for sure.

91裸聊视频淭he next step would be to really dig into the location in the hair, the structure, the protein, as well as then the behaviour of these critters,91裸聊视频� Martin said.

91裸聊视频淒oes this affect their fitness or is this just an artifact, some weird thing that happens when you live a nocturnal life? We don91裸聊视频檛 know, we don91裸聊视频檛 know.91裸聊视频�
