Raw Data from Experiment

Data of dispersal of individual red flour beetles within experimental arrays. As described in the manuscript: "We allowed populations of Tribolium castaneum to disperse across replicate linear arrays, manipulating current density (low = 18 adults, high = 90 adults), current habitat quality (low = 99.5% corn flour, 0.475% wheat flour, 0.025% brewer’s yeast; high = 98.2% corn flour, 1.71% wheat flour, 0.09% brewer’s yeast), and juvenile density (low and high) in a fully-factorial design (2 current densities x 2 current habitat qualities x 2 juvenile densities x 15–20 replicate dispersal arrays = 143 arrays). One-third of beetles within each array were experimental beetles that experienced either a low or a high juvenile density (n=18 or 90), while the remaining two-thirds of beetles were standardized beetles that experienced an intermediate juvenile density (n=40)."
