A data frame consisting of bivariate time series from an experiment for
studying prey-predator dynamics. The first time series consists of
the numbers of
prey individuals (Didinium natsutum) per ml measured
every twelve hours over a period of 35 days; the second time series consists
of the corresponding number of predators (Paramecium aurelia) per ml.
