Table 2.

Results of a simulation adding genetic variation in phenology (i.e. hatching or emergence date) to the genetic variation in growth rates of Xysticus (table 1). All simulations include R = 3 and are just for Xysticus acting as predator (potential generality). See table 1 for explanation of columns.

type of between-trait covariation	population		CV-ROP	links	cannibalism
phenology correlated with growth rates	high genetic variation	583.2 (0.8)	128.4	19	7921 (5.4)
	low genetic variation	1144.6 (1.6)	76.2	5	4114 (2.8)
phenology uncorrelated with growth rates	high genetic variation	307.5 (0.4)	196.0	18	5629 (3.9)
	low genetic variation	1066.6 (1.5)	84.6	5	3149 (2.2)
phenology alone	high genetic variation	374.3 (0.5)	179.2	17	3776 (2.6)
	low genetic variation	1002.6 (1.4)	93.6	5	2791 (1.9)
