Jaramillo P., Trigo M. M., Ramírez E., Mauchamp A., Insect pollinators of Jasminocereus thouarsii, an endemic cactus of the Galapagos Islands, Galapagos Research, 2010, 67:21-25
The study of a Santa Cruz population combines observations of morning flowering and visiting insects with flower isolation, a germination experiment and seedling growth measurements. It indicates a need for pollen transfer by an external agent, and separate limitations at the stages of germination and young plant survival. The discussion distinguishes the absence of autonomous self-pollination from undetermined self-compatibility, and proposes a relationship between population recruitment and irregular rainfall.
