Survival data set of chronic laboratory toxicity tests with Gammarus pulex freshwater invertebrate exposed to eight concentrations of one fungicide (propiconazole) during four days. Eight concentrations were tested with two replicates of 10 organisms per concentration. Survival is monitored at five time points.
data(propiconazole)
A dataframe with 75 observations on the following four variables:
replicate
A vector of class factor
with the
replicate code (SC
for the control and A1
to G2
for other profiles).
conc
A vector of class numeric
with propiconazole
concentrations in \(\mu mol.L^{-1}\).
time
A vector of class integer
with the time points
(in days from the beginning of the experiment \(t = 0\)).
Nsurv
A vector of class integer
with the number of
alive individuals at each time point for each concentration and each
replicate.
