#' Survival of Daphnia magna exposed to multiple stressors
#'
#' A data set of mixture toxicity experiments. Individuals of Daphnia magna were
#' exposed to combinations of food stress and multiple concentrations of the
#' pesticides esfenvalerate and prochloraz. The survival was recorded at 21 days
#' after contamination.
#'
#' @format A data frame with 58 rows and 4 variables:
#' \describe{
#'   \item{food}{The amount of food in percent.}
#'   \item{esfenvalerate}{The concentration of esfenvalerate in µg/L.}
#'   \item{prochloraz}{The concentration of prochloraz in µg/L.}
#'   \item{survival}{The mean survival in percent.}
