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.
Comparative assessment of capybara (Hydrochoerus hydrochaeris) welfare in protected, semi-anthropized, and anthropized environments in Argentina
Grantee: Débora Silvia Racciatti
Institution: Universidad de Buenos Aires, Argentina
Project summary
This project will assess how different levels of human disturbance are associated with behavioral, physiological, and health-related welfare indicators in capybara (Hydrochoerus hydrochaeris). Using camera traps, direct observations, non-invasive fecal sampling, and body condition assessments, the team will evaluate a suite of indicators and test not only whether they vary in predicted directions across environments, but how consistently they converge across welfare domains, identifying which measures most reliably discriminate conditions of higher versus lower welfare in free-ranging populations.
An evaluation of effective disturbance mitigation measures for European badgers (Meles meles) occupying setts during forestry operations
Grantee: Stephen McAuliffe
Institution: University of Brighton and Forest Research
Project summary
In order to avoid possible disturbance to European badgers, forestry guidance in England states that activities using heavy machinery should be prohibited within 20 meters of active badger setts. This research aims to validate that the approved noise and vibration mitigation buffer distances intended to prevent disturbance from anthropogenic activities are effective. Observations of badger behavior will be made in woodland habitats, and fecal cortisol metabolites will be collected for analysis. If changes in behavior and increases in cortisol levels are not found following exposure to forestry noise and vibration greater than 20 meters away, robust evidence will be provided to validate that badger welfare is not being adversely impacted by legally sanctioned forestry activities.
City living – assessing the welfare costs of urban living in spotted hyaena (Crocuta crocuta)
Grantee: Emma Stone
Institutions: Carnivore Research Malawi, University of the West of England
Project summary
Networks of green spaces and river corridors support a population of urban spotted hyenas in Lilongwe City, Malawi. However, human-wildlife conflict (HWC) is frequent. Using non-invasive techniques, this project will measure and compare the fecal and hair cortisol levels, mean body condition, tooth ware, hematological parameters, and disease in urban and rural populations of spotted hyenas. Behavioral experiments (exposure to novel objects and threatening scents) will also be used to assess individual boldness in urban and rural populations as a risk factor, which may increase propensity for HWC and therefore mortality and stress. Results will be used to inform policies to reduce HWC and implement welfare considerations as part of the population’s conservation management plan.
From rehabilitation centers to the wild: Evaluating brown bear stress using blood and scat parameters
Grantee: Morteza Naderi
Institution: Koç University
Project summary
Brown bears play a prominent role in the ecosystems of northern and eastern Turkey. However, there are serious long-term threats to their welfare and viability that are common to other large omnivores, such as habitat fragmentation and increasing contact with humans. For example, open garbage dumps are located across the bear’s distribution and affect behavioral patterns in bears, including seasonal migration habits, whereby the bears would normally move into different areas to exploit seasonal resources. This project will involve a collaboration with KuzeyDoga, one of the only nature conservation NGOs in Turkey, to monitor the behavior and stress physiology of individual free-living bears using GPS collars, camera traps, and blood and fecal glucocorticoids (GCs).
Introducing a novel tool to compare stress levels in captive and wild Macaca fascicularis
Grantee: Vets4welfare
Institution: Vets4welfare Foundation
Project summary
This project will compare cortisol concentrations in the hair of Indonesian monkeys from three groups: one in the wild, one that has been kept in captivity for the entertainment industry, and one in the process of rehabilitation following rescue from the entertainment industry. The aim of the project is to compare stress responses under wild, poor-welfare captive, and high-welfare captive environments. The hair cortisol data will be compared with veterinary and forensic records and other welfare-relevant observations (e.g. of infections or injuries) where possible. The researchers also intend to determine whether mistreatment in captivity leaves a signal in hair cortisol that could be detected after the fact and used to identify monkeys who have been illegally trafficked.
The impact of road noise on the welfare of free-living juvenile white-footed mice
Grantee: Michael Sheriff
Institution: University of Massachusetts Dartmouth
Project summary
This project will examine how road noise impacts the ability of juvenile white-footed mice in Massachusetts to respond to the threat of predation. Preliminary work has shown that experimental manipulation of road noise disrupts the foraging responses of (adult) small mammals to predation risk, possibly by masking their ability to perceive predators’ auditory cues. Perception of predation threat will be experimentally manipulated by auditory playback of owl noises at sites near and far from the highway, paired with controls at the same distances from the highway without auditory playback. Anxiety-related behaviors will be recorded in juveniles in an open field trap, and their feces will be studied to assess physiological stress and nutritional status.
