First of its kind lab in Canada telling time using animal teeth

On Wednesday, a brand-new lab inspecting wildlife tooth opened at Lethbridge School. It’s the primary of its form in Canada.

“The Wildlife Analytics Lab is beginning off specializing in cementum evaluation, which is technical jargon for wanting inside tooth to find out the age of animals,” stated Dr. Everett Hanna, an Environmental Sciences teacher at Lethbridge School.

He defined like cement, cementum holds tooth in place, and inside there are annuli, the ring-like bands and areas seen in tree trunks.

“Similar to in a tree the place we now have development rings, the identical rules apply. Sadly with a tree you may simply reduce it and take a look at the rings, in a tooth you should undergo fairly an elaborate chemical course of to get at these annuli which can be kind of embedded throughout the tooth roots,” stated Hanna.

From there, the lab gives age estimates for wildlife mammals to these within the fee-for-service program. In line with Hanna, this course of is useful for harvest allocation in looking or illness administration, and in some circumstances understanding reproductive historical past.

“In species like black bears, when females have younger cubs and so they’re lactating, the years by which they’ve these younger and so they’re lactating the annuli are nearer collectively, so you may clearly see years once they have younger and years the place they don’t,” stated Hanna.

The Alberta Skilled Outfitters Society (APOS) offered $145,000 from their Wildlife Administration Fund to fund the acquisition of recent gear from Leica, in addition to to rent scholar lab techs and a devoted lab technician.

“That cash was instrumental, it’s the rationale we’re the place we’re right here immediately,” stated Hanna.

Corey Jarvis, president of APOS explains it was a possibility for a made-in-Alberta resolution for a excessive demand space of analysis.

“We have to know and analyze, and Alberta wants that knowledge earlier than they will make good wildlife administration choices,” stated Jarvis.

“You needed to get an export allow up to now to ship wildlife components to the states and the prices have been in U.S. {dollars} and effort and time to get stuff down and again, so I feel it can [mean] much more well timed evaluation probably right here as nicely, so the advantages are nice throughout I feel on this system.”

As soon as the lab is in full operation Hanna has objectives of analyzing 4,000 to five,000 tooth per 12 months and sooner or later, growing a course of to assist monitor migratory patterns.

“If we are able to improve Canadian wildlife conservation by this contribution, practice college students, develop analysis alternatives, and develop this resolution right here in Lethbridge, I feel these are all win-win-wins,” stated Hanna.
