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.
Developing & refining behavioral assays for the measurement of ‘sentient welfare’ in gastropod molluscs
Grantee: Elizabeth Paul
Institution: University of Bristol, United Kingdom
Project summary
Compared to cephalopod mollusks, gastropod mollusks have been neglected in welfare research and public and legislative concern. This project will develop and refine key assays for the behavioral measurement of welfare in two gastropod species: the great pond snail (Lymnaea stagnalis) and the common garden snail (Cornu aspersum). The researchers will study the capacities of snails to experience consequences within two hypothesized domains of affective function: the first relating to a Punishment Avoidance System (associated with an animal’s responses to threats and punishments) and the second to a Reward Acquisition System (associated with an animal’s responses to opportunities and rewards).
Validating welfare indicators in an arachnid and their relationship to leg loss, a common defense strategy
Grantee: Ignacio Escalante
Institution: University of Illinois, Chicago
Project summary
This project will explore the welfare implications of leg loss, or “autotomy” — a common defensive strategy among animals. The project aims to validate welfare indicators within an understudied group of invertebrates, the Opiliones (Arachnida) in southwestern Costa Rica. Field and lab experiments will be used to test three potential behavioral welfare indicators: 1) movement patterns (approach vs. retreat), 2) speed, and 3) exploratory leg-tapping behaviors (count of leg taps) in response to positively and negatively valanced stimuli. These behaviors will be assessed when individuals are alone, in conspecific aggregations, and in barren versus complex housing. All experiments will include individuals with all legs and those with missing legs to assess how leg condition impacts welfare.
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.
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.
