Field and Laboratory Data on Cocoon Hatching Dynamics of Amynthas tokioensis

This dataset supports the manuscript “Annual Endogenous Cycle and Thermal Drivers of Cocoon Hatching in the Earthworm Amynthas tokioensis” and includes both field-collected and experimental data. It contains:

 

• Soil temperature records from 2014–2017, recorded every 6 hours at 5 cm depth using iButtons

• Earthworm collection data including date, location, stage, and size

• Laboratory incubation results from 2023–2024 analyzing cocoon hatching times and embryonic development stages under controlled temperatures

 

The dataset also includes an R script used for statistical analysis and figure generation (Kaplan-Meier survival curves, Cox models, and developmental outcome summaries).
