#' @description Database of thermosensitive period of development for sex determination.\cr
#' This database can be used with the functions plot() or info.nests().\cr
#' 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).\cr
#' If the metric for the stages before the TSP or after the TSP is not known, it will use the 
#' available information.
