Automated feeders have long fed mice, livestock, and poultry, but are incapable of feeding zoo animals such as gorillas. Gorilla food, consisting of cut vegetables and fruits, is too large to be dispensed by automated feeders. Instead gorillas are manually at a set time and location, which decreases the exercise and enrichment that accompanies their natural foraging. We designed and built [...]

Research into animal cognitive abilities is increasing quickly and often uses methods where behavioral performance on a task is assumed to represent variation in the underlying cognitive trait. However, because these methods rely on behavioral responses as a proxy for cognitive ability, it is important to validate that the task structure does, in fact, target the cognitive trait of interest [...]

The obesity epidemic is among the most serious and rapidly growing public health challenges of the 21st century. This rapid increase is concerning as obesity appears to negatively impact cognition and behaviour. Furthermore, some studies suggest that this negative effect could be carried across generations from both mothers and fathers although evidence is not consistent. Here, we attempt to [...]

The obesity epidemic, largely driven by the accessibility of ultra-processed high-energy foods, is one of the most pressing public health challenges of the 21st century. Consequently, there is increasing concern about the impacts of diet-induced obesity on behaviour and cognition. While research on this matter continues, to date, no study has explicitly investigated the effect of obesogenic diet [...]

Zebrafish (Danio rerio) are increasingly being used to model anxiety. A common behavioral assay employed for assessing anxiety-like behaviors in zebrafish is the “novel tank test”. We hypothesized that using deeper tanks in this test would result in greater between-individual variation in behavioral responses and a more ‘repeatable’ assay. After mapping the literature and identifying common [...]

1. Advances in datalogging technologies have provided a way to monitor the movement of individual animals at unprecedented spatial and temporal scales, both large and small. When used in conjunction with social network analyses, these data can provide insight into fine scale associative behaviors. The variety of technologies demand continuous progress in workflows to translate data streams from [...]
