Hynobius Salamander Hatching Timing and Morphological Trait Measurements

Field observation data from three experiments on the salamander species Hynobius retardatus. The dataset includes counts of hatched individuals, their developmental stages, and morphological measurements such as body length, head width, and gape width. It was authored by Aoi Murase and last updated on April 13, 2026.

Use Cases

• Modeling the relationship between hatching timing and morphological development based on the described trait measurements.
• Analyzing survival outcomes for early- versus late-hatched individuals based on the described Experiment 3 data.
• Comparing predator and prey size metrics using the body length and gape width data from Experiment 3.
• Statistical replication of the original study's findings using the provided R code for analysis and figure generation.

Strengths

• Includes associated R code for statistical analysis and figure generation, facilitating reproducibility.
• Released under a permissive CC-BY-4.0 license, allowing for broad reuse.
• Data is structured across three distinct experiments, allowing for comparative analysis.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small at 163.8 KB, indicating a limited scope and sample size.
