The size of a lynx family photographed on the Haines Road earlier this week fits with the cat's current population cycles, according to an Environment Yukon biologist. 

Earlier this week, photos of a lynx and her five young sunning themselves captured the of attention on social media.

Carnivore biologist Ramona Maraj said lynx can have up to eight kits, when the snowshoe hare, their main prey, are abundant.

"We're coming into what's known as a lynx high. Lynx cycle every 10 years with snowshoe hare. It's one of the more famous ecological phenomena," she said in an interview on CBC's A New Day. 

In low years, Maraj said lynx may have just one or two offspring. 

Some 'messiness' to the cycle

Maraj said the snowshoe hare populations have recently peaked and are now starting to collapse. Lynx populations usually lag by a year or two, meaning that their numbers may start to decline next year.

But Maraj said the cycle is actually quite complex, with factors like climate change playing a role. Sometimes, lynx will move off of hare and start eating squirrel, grouse and ptarmigan. 

"There's a little bit of messiness to it, but for the most part we do see a strong 10-year signal [cycle]."

She said the majority of research on lynx cycles has been done near Kluane Lake.

"It's pretty neat that such an amazing ecological phenomenon ... is studied here in the Yukon."
