Reproductive ecology of the carnivorous plant <italic>Pinguicula moranensis</italic> (Lentibulariaceae).

Abstract: The interaction of plants with pollinators can be a determinant of their reproductive fitness. However, information about the pollination biology of carnivorous plants is scarce. To increase knowledge of reproductive ecology of carnivorous plants we focused on <italic>Pinguicula moranensis</italic>. Specifically, based on the presence of large, zygomorphic and spurred flowers, we predicted higher reproductive fitness in cross‐pollinated than in self‐pollinated flowers. Within a plot of 51 m2 we characterised the reproductive phenology, including flower lifespan and stigmatic receptivity. We identified pollinators and their movement patterns within the plot. Breeding system was experimentally evaluated using hand‐pollination (<italic>i.e</italic>. autonomous, self‐ and cross‐pollination). Flowers of <italic>P. moranensis</italic> were visited by long‐tongued pollinators, mainly members of the Lepidoptera. Hand‐pollination experiments confirmed our prediction and suggest that flower traits might favour cross‐pollination. We mainly discuss the implications of the patchy distribution of plants and behaviour of pollinators on gene movement in this plant species, as pollination between genetically related individuals could be occurring.
