From Scat to SNP: Unlocking Prey Identities in Carnivore Diet with Dr. Charles van Rees
24/09/2026 | 1hIn this Research Review episode, we’re joined by Dr. Charles van Rees to dive into a groundbreaking 2026 paper from Oregon State University (published in Molecular Ecology Resources). We break down how single nucleotide polymorphism (SNP) panels and non-invasive scat samples (many located by detection dogs!) are allowing researchers to identify individual prey animals consumed by carnivores. Join Kayla and Dr. Charles van Rees for a crash course in genetics, filtering out mixed DNA samples, and what this means for understanding predator-prey dynamics in the field.

Patreon: Madison David - Join us for a fantastic conversation with Lauralea Oliver of k9inSCENTive about the art of selecting rescue dogs for detection work.
With over 25 years of professional experience, Lauralea brings a wealth of knowledge to the table, having selected and placed numerous working dogs with handlers and conservation projects across the country. She has mastered selecting the traits that make a shelter dog excel in the field- and, crucially, knows exactly when to walk away.
The core theme of this episode is simple but vital: "Say no to the maybes" and only move forward with a dog you are absolutely sure about.

Melissa McCue-McGrath gets humped and peed on professionally more than she thought she would in this line of work. She has written two books. The first, "Considerations for the City Dog" was written for her clients in Boston who needed support for living with dogs in an urban setting, and the second, "Misadventures of the World's Okayest Dog Trainer" is for people who are curious about what it's like behind the scenes working with clients and dogs.
Melissa paved the way as the first American resident certified by the British Animal Behavior and Training Council, thanks to the Professional Association of Canine Trainers, also based in the UK. She's a Victoria Stilwell Academy faculty advisor, a trainer for Grisha Stewart's dog training academy, and was part of a nationwide study to see if pet dog trainers, like Melissa, could train pet dogs - like many of your dogs at home - to find an invasive species. There were six dogs in Melissa's cohort two years ago, and this year, the year the invasive Spotted Lantern Fly is predicted to be in her home state of Maine, Melissa has a total of 22 dogs at the Animal Welfare Society in Kennebunk Maine who can find the invasive spotted lanternfly...in a controlled setting :)
