Predator Exposure Effects on Juvenile Amazon Molly Behavior Over Four Weeks

Four weeks of repeated behavioral trials on juvenile Amazon mollies reared with or without a visible predator. The dataset accompanies a study on how early-life predator exposure shapes behavioral development and individual variation under genetically and environmentally standardized conditions. Data includes activity, feeding duration, and visits to a feeding spot, compiled by Ulrike Scherer.

Use Cases

• Modeling behavioral development trajectories based on repeated activity and feeding measurements.
• Analyzing variance components (among-individual, within-individual) under standardized conditions.
• Testing the effects of early-life environmental cues on average behavior and behavioral variation.

Strengths

• Data collected under genetically and environmentally standardized conditions, reducing confounding variables.
• Behavior quantified repeatedly over four weeks with three trials per week per individual.
• Dataset is openly available under a CC-BY-4.0 license.

Limitations

• Row count and column-level documentation are unknown, requiring inspection after download.
• The dataset is small at 137.1 KB, indicating a limited scope and sample size.
