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.
WellSeal: Non-invasive quantification of welfare in lactating harbour seals
Grantee: Jess Harvey-Carroll
Institution: University of Gothenburg
Project summary
Limited availability of harbor seal birthing sites leads to intraspecific competition, forcing mothers to choose when and for how long to forage, and resulting in trade-offs between maternal and offspring welfare. These trade-offs may be exacerbated by fishing, as harbor seals swim large distances to obtain food. This project will use camera trap footage and 3D modeling to assess the influence of maternal welfare on time spent away from pups, and pup welfare during periods of maternal absence. Welfare will be assessed based on body condition, an index of the optimality of haul-out position, and a record of positive and negative interactions. The assessment will be aggregated at colony level to compare welfare between colonies with varying access to food.
Pre- and Post-release Welfare Indicators for Recovery Programs
Grantee: Laney Hayward Nute
Institution: University of Mississippi
Project summary
Captive-raised animals translocated to the wild often suffer high mortality. This project seeks to identify a set of pre- and post-release indicators of welfare to target released Attwater’s prairie chickens for management interventions. Pre-release, the coping styles of birds will be identified during routine cage transfers and handling. Following release, the fine-scale movements of released birds will be traced using customized data loggers. Investigating the association of pre- and post-release behaviors with body condition, daily environment changes, and survival, will identify which birds from future releases will need special attention to aid their survival. The researchers hypothesize that individuals with a more proactive personality will disperse further post-release and suffer higher mortality rates compared to more reactive individuals.
Developing a consensus profile of wild animal welfare: integrating non-invasive monitoring of the gut microbiome with stress physiology and behavior
Grantee: Sam Sonnega
Institution: University of Massachusetts Dartmouth
Project summary
This project will characterize the gut microbiome of white-footed mice and investigate its relationship with their stress physiology and behavior. Mice will be trapped and fecal samples collected to measure glucocorticoid concentrations and gut microbiome composition. Concurrently, open-field trials will be conducted to assess individual variation in cognitive bias. Perception of predation risk will also be experimentally manipulated by exposing mice to playbacks of predator noises. By correlating the gut microbiome with behavioral and endocrine metrics, a consensus profile of the mice’s welfare will be developed that reflects the complexity of their responses to environmental perturbations, and how those responses can scale up to population and ecosystem level changes via the demographic effects of stress in a “landscape of fear.”
Assessing the Welfare of Wild Olive Baboons (Papio anubis) at the Uaso Ngiro Baboon Project, Laikipia, Kenya
Grantee: Monica Wakefield
Institution: Northern Kentucky University and Iowa State University
Project summary
This project aims to assess the welfare of wild baboons using a holistic approach. The study takes advantage of almost 40 years of long-term ecological, demographic, health, and behavioral information on >170 individually known baboons, and will examine how various factors such as age, sex, and social rank correlate with individual welfare measures such as incidence of injury and disease, body mass, and pro-social or agonistic behaviors. The annual scale of the dataset will also enable the researchers to test how events such as droughts have affected welfare during specific periods, and how these effects may have varied according to individual animals’ demographic profiles and biographies.
The animal welfare of animal warfare: how inter-group interactions affect wild animal wellbeing
Grantee: Dominic Cram
Institution: University of Cambridge
Project summary
This project will investigate the welfare consequences of inter-group conflicts in wild Kalahari meerkats. It will use an established dataset of meerkat behavior, body weight, territory use, and reproduction, covering more than 500 inter-group interactions over 14 years. Identifying the short- and long-term welfare implications of inter-group interactions in meerkats will shed light on similar animal warfare in group-living insects, fish, birds, and mammals. Clarifying the circumstances that lead to the most harmful battles will provide a first step in understanding how their frequency could be reduced, which could limit the suffering they cause and enhance the welfare of group-living wild animals.
Development of octopus mind in the wild: a behavioral, ecological and evolutionary investigation into sentience and emotional states in Octopus insularis juveniles
Grantee: Michaella Andrade
Institution: Federal University of ABC
Project summary
There is evidence that evolutionary pressures can cause behaviors with opposite meanings to develop opposite forms, the way a frown is the opposite of a smile. One way to understand the expression of emotion in animals may therefore be to identify pairs of behaviors that are opposites. In octopuses, which are increasingly being recognized as sentient, colors can be signals of emotional valence during conflict and other situations. Yet no study has tested whether octopuses have opposite pairs of color signals. This project will produce descriptions of evolutionary and behavioral patterns that reflect the emotional states and sentience of juvenile octopuses, which may contribute to the welfare of octopuses and other invertebrates.
Determining the practical and statistical methods necessary for employing field-based metrics of welfare on wild, juvenile, birds
Grantee: Daniel Hanley
Institution: George Mason University
Project summary
Because welfare can vary between individuals and throughout the life of an animal, methods for measuring, assessing, and comparing welfare have been a barrier to our understanding of juvenile welfare. Initial investigations of welfare metrics are needed to estimate age-specific welfare in wild juvenile animals, to determine how they deviate from population-level estimates, and to extend methods and metrics to other systems. This study will examine welfare in free-living prothonotary warblers to establish standardized field and analytical procedures necessary to obtain age-specific animal welfare estimates. Prothonotary warblers are an ideal model system for studying age-specific welfare because they have well-defined life stages, face unique environmental risks, have variable survival, and nest within cavities, affording a degree of standardization and control.
It takes guts to grow in the city: the role of the gut microbiome in the welfare of juvenile urban birds
Grantee: Pablo Capilla-Lasheras
Institution: University of Glasgow
Project summary
Approximately 30 million blue tits hatch every year in UK cities, but around 63% die as juveniles. One reason for this may be that juvenile birds in urban habitats tend to have low-quality diets, causing stunted growth and increased early-life mortality. Research suggests that gut microbiome composition may contain indicators of an animal’s welfare, but this has received little attention in a wild animal context. This project will combine telomere attrition, begging behavior, and other health metrics with a study of juvenile birds’ gut microbiomes to investigate how to improve the welfare of juvenile blue tits in urban areas. It will also test the potential for gut microbiome enrichment to improve the life experience of juvenile birds in urban habitats.
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.
The impact of anthropogenic stressors on the affective state of juvenile Murray cod
Grantee: Rafael Freire
Institution: Charles Sturt University
Project summary
Many freshwater fish populations have severely declined as a result of human-caused changes in their environment. Population decline often results from an increased mortality rate experienced on the individual level, with likely implications for the welfare of individuals living through a period of population decline. This study will examine how differences in water quality and the presence of potential predators affect a behavioral indicator of welfare — judgment bias — in juvenile Murray cod (Maccullochella peelii). In the future, data about how juvenile fish respond to these factors could guide interventions for helping juvenile fish survive to adulthood in the wild.
