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.
Assessing behavioral and physiological welfare indicators for the Kashmir loach (Triplophysa kashmirensis)
Grantee: Misba Rehman
Institution: Sher-e-Kashmir University of Agricultural Sciences and Technology, India
Project summary
This project aims to develop and validate non-invasive behavioral and physiological welfare indicators for the Kashmir loach (Triplophysa kashmirensis). The researchers will use underwater cameras to record behaviors like activity, refuge use, foraging, and abnormal swimming patterns. Physiological welfare will be assessed using mucus sampling to measure cortisol concentrations and supplementary indicators including oxidative stress and immune markers. The team will validate indicators by testing their correlation with key water quality parameters. The project aims to establish the first field-based welfare assessment framework for this species and develop a transferable model for wild freshwater fishes inhabiting mountain stream ecosystems.
Raman spectroscopy as a novel non-invasive technique to assess wildlife welfare
Grantee: Teresa Romero
Institutions: University of Lincoln, University of Portsmouth
Project summary
Analysis of hormones accumulated in the hair has emerged as a non-invasive tool for measuring chronic stress in wildlife, but hair analyses are currently limited by variation in cortisol concentrations. This project will test whether Raman spectroscopy, which is suitable for the field and does not require sample pre-treatment, is a better way to use hair samples to assess steroid hormones. The planned methodology will make use of samples of mammalian hair with a known cortisol content using a control technique — liquid chromatography mass spectrometry — for comparison. The samples will be subjected to analysis by Raman to validate the technique and establish a robust analytical methodology for the non-invasive analysis of welfare biomarkers in wildlife.
Improving the welfare of translocated individuals - European mink as a case study
Grantee: Maria Diez Leon
Institution: University of London
Project summary
This project will assess how levels of two behaviors thought to track positive and negative welfare states — play behaviors and abnormal repetitive behaviors — influence post-release welfare metrics in two on-going reintroduction programs for the European mink. Fecal glucocorticoid metabolite levels will be measured to validate these behavioral indicators pre- and post-release. By differentially raising mink in conditions known to improve welfare, the researchers will investigate whether captive environments that promote play and decrease abnormal repetitive behaviors improve pre-release and post-release welfare, whether individual welfare state pre-release correlates with post-release welfare outcomes, and how the welfare of captive-born individuals differs from that of wild-born individuals.
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.
