Who We Are: The Yellowstone Ecological Research Center (YERC)

In 1995, when grey wolves were released in Yellowstone National Park as part of their U.S. Endangered Species Act recovery plan, coyotes were among the residents hearing their first howls. So were ...

Alpine Otters... Now Arctic Beavers!

Great story in the New York Times today about beavers moving into the Arctic, most likely as a result of climate change. Like our upcoming Alpine Otters project, this research sheds light on nature...

Bringing Space Age Technology to the Beartooth Plateau

Our project will use snow tracking and scat analysis, two of the oldest, simplest, and most effective techniques devised for learning more about animals like river otters. But how can we learn more...

Recent Evidence of River Otters on the Beartooth Plateau

The splash I saw upon arriving at Jordan Lake last summer seemed way too big to be a fish. But after waiting a couple minutes, no brown furry head popped up, so we continued on and set up camp. The...

Thank you, Marypat! And thanks for your support and all your help getting the word out about this project. We will be sure to name an otter "Old Neutriment"...

Thanks for the kind words and generous contribution, Steve! I think you know as well as anyone how much we care about the Beartooths and its inhabitants (and how much we like getting out into the Beartooths to study its inhabitants!)

Cool photos, and congrats on getting funded! In the weasel photo, is that a hunk of black bear hanging in the tree? And for your wolverine traps, interesting to see you use dimensional lumber instead of more natural materials like Copeland's original log cabin trap design (although I do recognize that good logs "might" be hard to come by in your study area, and that the resident willows ain't gonna' cut it for a wolverine trap.) Do you think there is any loss of trap efficacy using the dimensional lumber? It would be interesting to do (albeit difficult to fully control and interpret) a comparative test in a forested environment. Shaping the natural materials just so does seem like it would be a time-consuming pain on-site, whereas the dimensional lumber seems like it would save a lot of time (when I built those traps for foxes I did not have to be so precise since a fox won't chew his way out like a wolverine would)....

The free software ML-Relate might be worth looking into for a cheap way to assess relatedness... good luck!

You're welcome, Angie! For effective research (as in, to make the most of limited time and limited funding), we usually need to focus on a very specific set of questions. Yet to actually have an important impact, we need to make sure to place those questions in the context of the bigger picture (there's probably an ecosystem metaphor here). I had a college professor who would always say "it doesn't matter how many primary feathers are on the wing of the golden-crowned warbler" (or something like that), "what matters is: who cares about these birds and their feathers? why is counting them important? what is the gap in knowledge we are addressing with this research?" So thanks to experiment.com for providing this "lab note" section, allowing us to put things in context, provide more background, and have conversations like this. And thanks to you, Angie, for your interest and support!

Thanks! And I think the outreach and support from within the experiment.com community has been pretty awesome too!

SPECIAL UPDATE: Since this Lab Note was posted, I was contacted via experiment.com's messaging service with an additional otter observation in the study area! The report was of tracks observed last month around the inlet of Kersey Lake and nearby streams. It is exciting to know that the word is getting out about this project, and that folks are keeping an eye out for otters and otter sign in the Beartooths. If anyone else has any observations to report, please contact me, and better yet, try to (1) estimate the number of otters present, and (2) collect track measurements (widest width and longest length NOT including claws) and slide widths from each individual. Thanks!

Thanks Emily! I will be sure to put Sam to work (and believe me, I've already told him all about it). Besides, he and the otters have a lot in common: like the snow, catch a lot of fish, show up in random places all over the Beartooths...

Hi Tom, we talked about my fox project a few years ago. Glad to see you are embarking on grad school with an exciting and important project. Good luck!
