Reporting guidelines for terrestrial respirometry: Building openness, transparency of metabolic and evaporative water loss data

Respirometry is an important tool for understanding whole-animal energy and water balance in relation to their environment. Consequently, the growing number of studies using respirometry over the last decade warrants reliable reporting and data sharing for effective dissemination and research synthesis. We provide a checklist guideline on five key areas to facilitate the transparency and [...]

Switching to bioplastics may exacerbate ingestion of lost and discarded fishing gear by marine invertebrates

Bioplastics are argued to be more environmentally sustainable than conventional plastics. Yet, little is known about how bioplastics degrade in marine environments or their likelihood of being ingested by animals. We measured changes in the weight of biodegradable, semi-biodegradable, and non-biodegradable fishing gears (soft plastic lures, SPLs) in or out of seawater over 14 days. We then [...]

Quantifying clearance rates of restored shellfish reefs using modular baskets

Shellfish reefs are among the most degraded ecosystems globally, prompting substantial efforts to restore them. While biodiversity gains of restored reefs are well documented, other ecosystem services such as water filtration remain poorly quantified. We present a novel way of measuring water filtration by restored reefs using modular restoration structures called Robust Oyster Baskets (ROB 400). [...]

ForageFeeder: a low-cost open source feeder for randomly distributing food

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 [...]

Repeatability of performance within and across contexts measuring behavioral flexibility

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 [...]

Intergenerational effects of overfeeding on aversive learning in zebrafish (Danio rerio)

Hamza Anwer, Dominic Mason, Susanne Zajitschek, et al.

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 effects of an obesogenic diet on behaviour and cognition in zebrafish (Danio rerio): traits average, variability, repeatability, and behavioural syndromes

Hamza Anwer, Rose E O'Dea, Dominic Mason, et al.

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 [...]

An efficient new assay for measuring zebrafish anxiety: tall tanks that better characterize between-individual differences

Hamza Anwer, Dominic Mason, Susanne Zajitschek, et al.

Subjects: Animal Experimentation and Research, Life Sciences, Research Methods in Life Sciences

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 [...]

Workflow for constructing social networks from automated telemetry systems

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 [...]
