Survival data set for Daphnia magna exposed to dichromate
during 21 days
Description
Survival data set of chronic laboratory toxicity tests with
Daphnia magna freshwater invertebrate exposed to six concentrations
of one oxidizing agent (potassium dichromate) during 21 days. Six
concentrations were tested with one replicate of 50 organisms per concentration.
Survival is monitored at 10 time points.
Usage
data(dichromate)
Format
A data frame with 60 observations on the following four variables:
replicateA vector of class numeric with the
replicate code (1).
concA vector of
class numeric with dichromate concentrations in mg.L^{-1}.
timeA vector of class integer with the time points
(in days from the beginning of the experiment t = 0).
NsurvA vector of class integer with the number of
alive individuals at each time point for each concentration and each
replicate.
