Database of thermosensitive period of development for sex determination

Description

Database of thermosensitive period of development for sex determination.
This database can be used with the functions plot() or info.nests().
The attributes TSP.begin.stages and TSP.end.stages for each dataframe give respectively the first and the last stages for TSP. Then the metrics for the limits of TSP are the average sizes before and after the TSP (see example, below).
If the metric for the stages before the TSP or after the TSP is not known, it will use the available information.

Usage

TSP.list

Format

A list with dataframes including attributes
