Growth and metamorphosis data from a rearing experiment on Rana ornativentris

Amphibian larvae exhibit high plasticity in response to environmental conditions such as food and temperature, determining the timing and size of metamorphosis. While extensive research has been conducted on the mechanisms governing when and at what size metamorphosis occurs, specific models indicating species-specific metamorphic points have not been established. To create such a model, we conducted a rearing experiment using Rana ornativentris larvae as an example. We reared the larvae under different feeding conditions, monitored their growth, and recorded the number of days to metamorphosis and the body size at metamorphosis., R. ornativentris tadpoles were reared in a laboratory to obtain data on individual growth curves and consequential actual size and age at metamorphosis. Variations in aquatic growth rates were created by varying the amount of available food.
Two egg masses were collected from the field on April 9, 2017 and incubated until they hatched. When tadpoles reached Gosner’s stage 25 (Gosner 1960) on April 17, they were individually placed in a plastic container (129-mm diameter, 72-mm height) with 300 mL of aged tap water (day 0). Individuals were randomly assigned to one of the six food treatment groups (shown below) with seven individuals per group. In total, six or nine individuals that hatched from each egg mass were photographed with a scale to estimate the initial body weight using a formula for the relationship between snout-vent-length (SVL) and body weight obtained in another study (W(mg) = 206 × SVL(mm)2.85, Iwai et al. 2019). Containers were incubated (MIR-254-PJ or MIR-554-PJ, Panas..., , # Growth and metamorphosis data from a rearing experiment on Rana ornativentris

## Description of the Data and file structure

Sheet \"weight\"
Growth data for rearing experiment of Rana ornativentris tadpoles.
The first row shows individual ID, and the first column shows the time (day).
Data are shown as body weight (mg).

Sheet \"Larval period\"
Larval period of Rana ornativentris tadpoles.
The first column shows individual ID, and the second column shows the larval period (day).

There were six levels of food conditions.
A: 1.6 mg/day
B: 2.5 mg/day
C: 3.2 mg/day
D: 4.1 mg/day
E: 5.0 mg/day
F: ad libitum
The first letter of each ID name represents the food condition.
