Meet our grantees
Wild Animal Initiative funds academic research on high-priority questions in wild animal welfare.
The goal of our grants program is to fund research that deepens scientific knowledge of the welfare of wild animals in order to better understand how to improve the welfare of as many wild animals as possible, regardless of what causes the threats to their well-being.
We showcase our grantees and their projects here and continuously update this page as new projects are added.
Drivers of welfare in American pikas (Ochotona princeps)
Grantee: Johanna Varner
Institution: Colorado Mesa University
Project summary
Pikas (Ochotona princeps) in alpine habitats have recently faced population losses and range retractions. Declines are most prominent in isolated mountain ranges with limited high-elevation habitat, like the La Sals, where pikas are consequently likely to experience lower welfare. This project will assess the welfare of pikas in the La Sals through patterns of survival, population demographics, physiological stress, body condition, ectoparasite load, and hydration. The researchers will also test hypotheses correlating these indicators to habitat quality, and investigate resource competition between pikas and mountain goats.

Project summary
Due to recent population losses and range retractions, pikas (Ochotona princeps) are considered a sentinel for climate change in the alpine. However, declines are most prominent in isolated mountain ranges with limited high-elevation habitat, like the La Sals. Surrounded by low-elevation desert in all directions, pikas in the La Sals are likely to experience lower aggregate welfare (i.e., steeper population declines, greater physiological stress, and lower survivorship). This project will assess the welfare of pikas in the La Sals through patterns of survival, population demographics, physiological stress (fecal glucocorticoid metabolites; FGM), body condition, ectoparasite load, and hydration. The researchers will also test hypotheses correlating these welfare indicators to aspects of habitat quality. Finally, they will also investigate resource competition between pikas and mountain goats as another potential factor in pika welfare.
Why we funded this project
This project addresses our research priority of understanding the welfare implications of competition and other conflicts of interest between wild animals. It also focuses on a highly numerous species, the American pika. In that context, we appreciate that this project will model habitat quality on the spatial scale relevant to individual pika when assessing its association with their welfare. Finally, we value that they will use a wide variety of welfare indicators, representing the domains of physiology, behavior, and environment/demography, with each strengthening interpretation of the other.
