Table 1.
Realized inaccuracy values calculated from locations of pollen deposition on 12, 23 and 15 bumble-bees visiting Pedicularis densispica, P. tricolor and P. dichotoma, respectively (pollen deposition inaccuracy) and stigma contact tallied from photographs of fluorescent powder on bees and bees on flowers
| Pedicularis species | Fitness indicator measured | Mean2-scaled inaccuracy | Proportion of inaccuracy due to deviation from optimum (%) | Proportion of inaccuracy due to imprecision (%) |
|---|---|---|---|---|
| P. densispica | Dyed pollen | 0·258 | 17·9 | 82·1 |
| Total pollen | 0·367 | 31·9 | 68·1 | |
| Stigma contact position | 0·156 | 48·0 | 52·0 | |
| P. tricolor | Dyed pollen | – | ||
| Total pollen | 0·159 | 35·2 | 64·8 | |
| Stigma contact position | 0·153 | 62·3 | 37·7 | |
| P. dichotoma | Dyed pollen | – | ||
| Total pollen | 0·068 | 16·9 | 83·1 | |
| Stigma contact position | 0·016 | 57·2 | 42·8 |
