Data for flatworm-Daphnia trial under light pollution

(from the manuscript)<br>"To explore the effects of flatworms on <i>Daphnia</i> abundance under artificial light at night (ALAN), we conducted a population growth experiment over 19 days. The experimental design consisted of a flatworm treatment (flatworm absent / present) crossed with an ALAN treatment (dark at night / light at night), using four replicates per treatment combination (N = 24)....The experiment ran for 19 days, during which we counted the number of <i>Daphnia</i> three times per week."<br><br>The column names in the data set are self explanatory.
