Reproduction and survival data sets for Daphnia magna exposed to
chlordan during 21 days
Description
Reproduction and survival data sets of chronic laboratory toxicity tests with
Daphnia magna freshwater invertebrate exposed to six concentrations
of one organochlorine insecticide (chlordan) during 21 days. Six concentrations were
tested, with 10 replicates per concentration. Each replicate contained one
organism. Reproduction and survival were monitored at 22 time points.
Usage
data(chlordan)
Format
A data frame with 1320 observations of the following five variables:
replicateA vector of class numeric with
the replicate code (1 to 60).
concA vector of
class numeric with the chlordan concentrations in μ
g.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.
NreproA vector of class integer with the
number of offspring at each time point for each concentration and each
replicate.
