Yes. Hybrids were not significantly different from their parental species in survivorship or fecundity in filed plots in situ (in Brazil). Those data are in this table.

Hybrids also competed well for pollinator services (Fig. below). Hybrids were visited more often than their frequency in the plots would have predicted in the lixo plot, and at approximately the expected rate in the other two plots.

Figure: Percentage of pollinator visits (bars) to N. alata, N. forgetiana or their F1 hybrid in mixed plots. Lines indicate the percentage of each type of plant in each plot, i.e., the expected pollinator visitation rate if pollinators had no preference. Black bars indicate large hawkmoths and white bars indicate hummingbirds. Observed visitation rates (bars) were significantly different (by X²df=2,) from expected rates (lines) in all cases at the p<0.001 level.
