Description

Reproduction and survival data sets of chronic laboratory toxicity tests with snails (Lymnaea stagnalis) exposed to six concentrations of cadmium during 28 days. Six concentrations were tested, with six replicates per concentration. Each replicate contained five organisms. Reproduction and survival were monitored at 17 time points.

Usage

Format

A data frame with 612 observations of the following five variables:

replicate

A vector of class numeric with the replicate code (1 to 36).

conc

A vector of class integer with the cadmium concentrations in μ g.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.

Nrepro

A vector of class integer with the number of clutches at each time point for each concentration and each replicate.
