Reproduction and survival data sets for Daphnia magna exposed to
cadmium during 21 days
Description
Reproduction and survival data sets of chronic laboratory toxicity tests with
Daphnia magna freshwater invertebrate exposed to five concentrations
of cadmium during 21 days. Five concentrations were
tested, with four replicates per concentration. Each replicate contained 10
organisms. Reproduction and survival were monitored at 10 time points.
Usage
data(cadmium1)
Format
A data frame with 200 observations of the following five variables:
replicateA vector of class numeric with
the replicate code (1 to 20).
concA vector of
class numeric with the cadmium 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.
