Arroyo-Pérez E., Jiménez-Sierra C. L., Zavala Hurtado J. A., Flores J., Shared pollinators and sequential flowering phenologies in two sympatric cactus species, Plant Ecology and Evolution, 2021, 154(1):28-38, doi: 10.5091/plecevo.2021.1544
One year of observations of 231 Ariocarpus kotschoubeyanus and 212 Neolloydia conoidea plants in Tolimán compares the phenology of the co-occurring species. Two-day series of flower observations show three shared bee taxa and different proportions of their visits. The paper includes flower structure and activity and controlled pollinations, with a clear distinction between fruit set and seed set. During the annual cycle studied, flowering peaks of the two cacti occurred at different times.
