| Neighboring species | Target species | Effect value |
|---|---|---|
| sticky catchfly | common cow-wheat | 0.2379 |

Researchers Carolina Laura Morales and Anna Traveset gathered data about flowering plants growing alongside each other in various locations. In each case, the researchers identified one plant as a “target species” and a nearby plant as a “neighboring species.” The researchers then calculated a value to show how the neighboring species affected pollinator visits to the target species. The table shows that the prickly pear had an effect value of __________
