Description
Miguel Munguía-Rosas and co-authors studied why two tropical shrubs on the Yucatan Peninsula rarely cross-breed, in a 2023 paper. The shrubs are close kin and grow side by side. Barriers can act before a seed forms, like mismatched flowering times, or after. Past reviews lean on temperate herbs, so tropical shrubs may differ.
The team measured each barrier stage for the pair. Flowering overlap, pollinator visits, and pollen fit inside the flower were all checked. They weighed how much each barrier adds to total isolation. They also tested whether isolation runs stronger one way than the other. Results help explain how plant species split in the tropics.
