Wolves use their noses to track their quarry by its scent. Now a scientist is turning the tables, building a handheld device that analyzes the odor of wolf scat to determine the age, gender, and individual identity of the animal that left it.
The goal is to improve estimates of the size and demographics of endangered Mexican gray wolf populations, and ultimately to help bring back the wolf and restore greater balance to the forests of the southwestern U.S. and Mexico.
The Mexican gray wolf (Canis lupus baileyi) is "the smallest, southern-most occurring, rarest, and most genetically distinct subspecies of gray wolf in North America," according to a U.S. Fish and Wildlife Service (USFWS) website.

Re: Device may tell more about wolves by examining scat
- That is pretty interesting! I can attest to the cost of genetic analyses like DNA barcoding, where extraction, amplification and sequencing per sample is costly. I can't come up with a price off of the top of my head though. Too many reagents and other factors like paying the person doing it.
That's interesting how they can extract the same sort of information as a genetic analyses might, but the accuracy isn't very impressive for more fine grain studies. DNA barcoding has a much more reliable identification than this gas chromatography method, but then again barcoding cannot identify individuals, only haplotypes and species.
I would be interested to find the papers about this. I am wondering if anyone has barcoded Mexican gray wolf scat!

Re: Device may tell more about wolves by examining scat
It's truly sad that someone would want to eradicate an animal. However, I understand the need to protect livestock. I just hope that nature will find a balance, and that the Mexican grays might one day flourish again. Kudos to Burnham! I hope his methods prove valuable in the research of this species. Interesting find, Koa.
Let me explain
This ugliness, this cruelty, this repulsiveness
It will all die out
And now, I cry for all that is beautiful

You certainly know more about the technical side of DNA and various methods than I do, so I'll take your word for it. Though, I can certainly understand it being rather costly.Nordue wrote:

It is a rather complicated matter. In regards to Mexican wolves "flourishing again," I regret that I am not as hopeful. If you'd like, you can certainly provide your thoughts/opinions in this thread, as well:Opheya wrote:It's truly sad that someone would want to eradicate an animal.

This is a truly fascinating idea, I would like to hear the findings of said device when that report comes out!

Re: Device may tell more about wolves by examining scat
This is an amazing idea! Talk about biomimicry–scat was meant to be sniffed. I really hope it takes off with wolves and other endangered animals.
