Data were collected in the field from a common garden experiment conducted in 2011, near the town of Molas (Yucatan, México). These data include the number of fruits, seed predators, and seeds rescued by parasitoids from seed predator consumption, used to calculate relative fitness under scenarios of: one trophic level (potential seed number, i.e. fruit#*mean # of seeds per fruit), two trophic levels (potential seed # - seeds consumed by seed predators assuming no seed rescue [seed predator #*mean # of seeds per fruit]), and three trophic levels ([potential seed # - seeds consumed] + seeds rescued by parasitoids). Abbreviated headlines are as follows (from left to right): plant maternal family ("genotype"), fertility treatment (NF = not fertilized, F = fertilized, "treatment"), individual plant sampled ("plant"), number of recorded fruits ("fruit#"), number of fruits with a seed predator (i.e. seed predator abundance, "seedpredator#"), number of seeds consumed by seed predators assuming no seed rescue ("consumedseed#(no rescue)"), and the number of rescued seeds by parasitoids ("rescuedseed#"). Data were collected over a two-month period (November-December) in 2011
