Demographic models
of growth and mortality can be used to infer the age
structure of tropical forest trees, but direct measurements are
required to
confirm model predictions. Using
radiocarbon isotope dating, tree age was directly determined for 44
large trees
from 15 species. Results demonstrated
that Central Amazon trees can unexpectedly live for more than 1000
years, and
that the mean age for meter-diameter trees was about 500 years (Chambers
et al.
1998, Chambers
et al. 2001b). Recently, broader
forest age structure study at a number of Amazon sites was carried out
by a Brazilian post-doctoral
researcher in our group (Vieira
et al. 2005). |
