Table 2. Temporal variation in pollen dispersal distance in a population of Tabebuia aurea in a cerrado area of Central Brazil, in two flowering seasons.
| Season | N | Mean PD (s.d.) (m) | Max PD (m) | Median PD (m) | Ne | Ae (ha) |
|---|---|---|---|---|---|---|
| 2004 | 309 | 307.78 (438.80)a | 2339 | 118.00 | 786.37 | 120.98 |
| 2005 | 328 | 396.26 (546.77)b | 2608 | 161.00 | 1220.96 | 187.84 |
Ae, effective neighborhood pollination area (hectares); N, number of seeds analyzed; ; Ne, effective population size; PD, pollen dispersal distance (meters).
The analyses were based in 21 progeny arrays.
Mean PD values were statistically different, P = 0.017.
