Fern environmental sex determination data
Description
Sex determination (male and female) data at ecologically relevant glucose, N, and P concentrations and stoichiometries, at both ambient and elevated levels of CO_2
. The term "ameristic" denotes gametophytes with only male gametangia, while the term "meristic" refers to gametophytes with female or female and male gametangia.
Usage
data("SexDeterm")
Format
A data frame with 156 observations on the following 11 variables.
CO2.Level
a factor with levels
Ambient
Elevated
CO2 levelsBlock
a numeric vector, the elevated CO2 experiment was completed in 2 blocks
Glucose.Level
the number of C atoms relative to the number of P atoms, with 5 indicating the presence of 6 micromolar glucose and 0 indicating the absence of glucose in the growth media
N.Level
the number of N atoms relative to the number of P atoms
P.Level
the number of P atoms relative to the number of N atoms
C.N.P
the ratio of C to N to P atoms, a factor with levels
