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.
Empirical assessment of welfare in wild American mink and Eurasian otters: the effects of intra- and inter-specific population density
Grantees: Lauren A Harrington, Maria Diez Leon
Institutions: Oxford University
Project summary
This project seeks to determine whether the welfare of American mink is negatively impacted in the presence of high densities of Eurasian otters, whether both species’ welfare is compromised at relatively higher densities of conspecifics, and whether there is a seasonality to welfare impacts. The project will also assess whether behavioral time budget shifts in mink are associated with higher chronic stress levels as a proxy for negative impact on mink welfare. These questions will be addressed by measuring welfare through several different domains, including behavioral (exploratory behavior, vocalizations), physical (body condition, ectoparasite load), and physiological (telomere length, fecal glucocorticoid metabolites and hair cortisol) metrics.

Project summary
This project seeks to determine whether the welfare of American mink (Neovison vison) is negatively impacted in the presence of high densities of Eurasian otters (Lutra lutra), whether both species’ welfare is compromised at relatively higher densities of conspecifics, and whether there is a seasonality to welfare impacts.

Why we funded this project
This project has the potential to contribute significant information to the understanding of intra-specific density-dependent welfare and to the understanding of network effects among predator-prey and competitor interactions of wild animals. Its unusually diverse set of welfare metrics will allow for cross-validation, strengthening both this project and other projects applying the same metrics. The investigators each have a strong background in animal welfare and have made efforts to better align their work with Wild Animal Initiative’s priorities for wild animal welfare, which makes them good candidates to carry forward the validation of these welfare indicators (particularly telomere attrition, which is still relatively immature in its use as a welfare indicator).

Mapping welfare for conservation management
Grantee: Lisa Olivier
Institution: Game Rangers International
Project summary
This project will monitor behavioral and physiological parameters in African elephants over one year to map their perception of their environment. The aim is to test this approach’s potential as a leading indicator that is easy to measure, responds quickly to ecosystem changes, and highlights potential detrimental impacts. These measures will be aggregated to define a scale representing the animals’ perceptions of threat that can be estimated for a given time and place. The researchers will then project this data onto maps to identify areas of high and low welfare. The project will help conservation practitioners create management plans to protect wild animals by providing a head start in assessing changes in their surroundings.
Grantee: Lisa Olivier
Institutions: Game Rangers International, Zambia
Grant amount: $29,791
Grant type: Small grants
Focal species: African elephant (Loxodonta)
Conservation status: Endangered
Disciplines: Animal behavior, animal welfare science, wildlife management
Research location: Zambia
Project summary
To effectively steward wild animal welfare, leading indicators are needed that predict the future rather than summarizing the past. These must be easy to measure, respond quickly to ecosystem changes and highlight potential detrimental impacts that need addressing, including anthropogenic activities. This project aims to test the approach of mapping wild animals’ perception of their environment by monitoring an array of behavioral and physiological parameters in African elephants over a year as they navigate the landscape. These measures will be aggregated to define a scale representing the animals’ perceptions of threat that can be estimated for a given time and place. The researchers will then project these data onto maps to identify areas of high and low welfare, where animals may be feeling alternatively secure or fearful. The researchers intend for the project to help conservation practitioners create better management plans to protect wild animal populations by providing a head start in assessing changes in their surroundings.
Why we funded this project
We are excited by this project’s analysis of a long-term longitudinal dataset because of the importance of understanding how wild animals’ welfare varies with demographic factors such as age and sex, as these groups often face different challenges and have different ecological and behavioral requirements, and negative welfare impacts that fall on young individuals may also have ripple effects throughout their lives. We also appreciate this project’s holistic approach. The long-term monitoring means it is possible to consider not only the usual downstream welfare indicators based on health and behavior, but also upstream factors that might influence them, such as social interactions and exposure to predators.
