An article by science journalist Livi Milloway chronicles an "ah-ha" moment we had in Yellowstone National Park. The story published in The Wildlife Society Bulletin, titled An herbivore by any other name, unpacks how Hannah Hoff's recent paper in PNAS challenges the status quo when it comes to how scientists study and understand wildlife diets. 

Led by Hannah Hoff, in collaboration with the National Park Service and the Brown University Herbarium, the lab just published a blockbuster paper that summarizes, critiques, and enhances how ecologists tend to talk about what wildlife eat. 

The Apportionment of Dietary Diversity in Wildlife was published by PNAS on July 14th. There are some surprising and potentially sensitive elements to the story—both for how we monitor and manage wildlife populations and for how we address our implicit biases when observing and reporting on wildlife as scientists.

A new paper from the lab was led by postdoc Bethan Littleford-Colquhoun and published in Royal Society Open Science: "Body size modulates the extent of seasonal diet switching by large mammalian herbivores in Yellowstone National Park." The paper is free to read and download.

Beth used cutting-edge genetic and GPS-tracking technologies to test age-old ideas about why animals select the foods that they do. The work involved collaboration from experts in wildlife ecology and management, genomics, remote sensing, and botany -- with contributions from the National Park Service, several citizen science organizations, and funding from NSF as well as the Department of Interior. 

As Beth summarized in an interview with News@Brown, we have come to more accurately understand wildlife populations as a collection of animals that can respond individualistically to changes in their environment. From summer to winter, animals have to radically change the kinds of foods they eat. But it's not just that: they also have to take care to update their overall foraging strategy as they shift from foraging socially as part of a large herd to foraging more independently for their own unique sets of resources.

It feels good to have more of the lab getting back into the swing of fieldwork after the worst years of the early pandemic!

The lab has always maintained some field activity throughout the pandemic. Ezequiel has been remote from field sites across Argentina, Robert and Peter have been keeping active at Mpala in Kenya, and Colin (and the lizard team) as well as Amanda (and the terrapin team) had managed to keep active around the northeastern US. But a lot of us had to cut back or go it alone more than we would have liked. The tide is turning, though!

This summer we have had a group led by Beth (postdoc), Hannah (incoming grad student), and Maddy (UTRA student) at Yellowstone -- collecting dung, surveying plants, coordinating with collaborators -- with support from our scientific partners at the National Park Service and the Brown University Herbarium. Amidst the ongoing recovery from disastrous flooding along the Yellowstone River, we were able to get out into the field together to advance a number of priority projects for the lab. 

We are super grateful to funders: NSF (CAREER & EPSCoR award), Department of Interior (Cooperative Agreement), Brown University (UTRA & IBES).
