Table 1. Parameters of the plant–pollinator networks.
| 2007 | 2008 | 2009 | 2010 | |
| Plant species (total 138) | 79 | 88 | 100 | 108 |
| Plants as % of total species | 59.4% | 66.2% | 75.2% | 81.2% |
| Mean links per plant (± SD) | 5.7±7.2 | 8.9±7.7 | 8.4±7.1 | 7.2±5.6 |
| Maximum links in plant | 43 | 45 | 33 | 26 |
| Pollinator species (total 347) | 126 | 128 | 149 | 149 |
| Pollinators as % of total species | 38.1% | 38.7% | 45.0% | 45.0% |
| Mean links per pollinator (± SD) | 3.6±4.8 | 6.12±8.6 | 5.7±7.8 | 5.2±8.4 |
| Maximum links in pollinator | 40 | 58 | 51 | 71 |
| Interactions (total 2293) | 452 | 790 | 847 | 781 |
| Interactions as % of total interactions | 19.7% | 34.5% | 36.99% | 34.1% |
| Connectance | 4.54 | 7.01 | 5.67 | 4.85 |
| Nestedness | 0.968** | 0.952** | 0.957** | 0.963** |
| NODF | 19.17** | 25.44** | 29.43** | 32.10** |
Values are given for observations made in each year as well as the entire 4-year study period. Connectance is the percentage of interactions divided by the number of possible interactions; Nestedness is (100−T)/100, where T is the temperature. NODF (Nestedness based on overlap and decreasing fill) values are explained in the text (Methods). (* P<0.05; ** P<0.01).
