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.
Acoustic indicators of welfare in neotropical frogs: Calls as early-warning signals of sublethal suffering related to infection and environmental stress
Grantee: Erin Wall
Institution: Wavelength Animal Communication Science and University of Texas at Austin, United States
Project summary
Emerging evidence indicates that frog call characteristics are modulated by environmental and physiological conditions, offering the potential for rapid insights into an individual’s welfare. This project will examine the relationship between environmental conditions, physiology, and behavior to connect indices of welfare to variation in acoustic signals in neotropical frogs in Panama. By linking these measures to natural levels of sublethal infection and variation in environmental conditions, the researchers will aim to identify acoustic signatures of welfare and develop a rapid, non-intrusive welfare detection tool for thousands of species of vocalizing frogs.

Project summary
Climate change, habitat loss, and infectious disease are creating compounding challenges for frogs, yet we have limited tools to monitor the behavioral and physiological consequences of those challenges, assess frog welfare, or detect sublethal suffering. Emerging evidence indicates that frog call characteristics are modulated by environmental and physiological conditions, offering the potential for rapid insights into an individual’s welfare. This project will examine the relationship between environmental conditions, physiology, and behavior to connect indices of welfare to variation in acoustic signals in neotropical frogs in Panama. By linking these measures to natural levels of sublethal infection and variation in environmental conditions, we aim to identify acoustic signatures of welfare and develop a rapid, non-intrusive welfare detection tool for thousands of species of vocalizing frogs.
Why we funded this project
Along with supporting an early-career researcher, this grant will deliver a behavioral assessment framework and acoustic classifier tool for anurans to deepen our understanding of welfare in this diverse taxon and address the need for evidence-based, scalable welfare assessment methods.
