Table 2 Explanatory power of top SEMs.

Summary of top SEMs explaining predation intensity for each seed × predator type (from table S2). Data were arcsin-transformed and standardized to means = 0 and SD = 1 before analyses; hence, estimates are for relative comparison only. Full ranking of all 15 SEMs is shown in table S2.
