Distribution of canopy heights along the elevational gradient. Percentages of measurements different height classes are coded left to right as: < 2 m, black; >2–5 m, red; >5–10 m, yellow; >10–15 m, blue; >15 m green. N = 441 at each site on a 5 x 5 m grid.

Rates of basal area residence time along an elevational transect in Costa Rican rain forest. Basal area residence time was calculated as the mean plot basal area over the interval divided by the mean rate of plot basal area addition (stocks divided by flux).
