Females and males of three tree species did not differ in growth or mortality over an interval of 9.5 years. Comparing between sexes and across species, there was no consistent pattern of effects of short-term (1 year) growth and fecundity on longer-term gorwth or mortality. Effects of size were significant (but minor) for growth in one species, and were significant for mortality in two species. Soil type affected mortality in one species, but affected growth in all three species. Sex and size are not consistently strong bases for predicting the performance of adult trees.
三种树种的雌性和雄性在9.5年的时间间隔内，生长或死亡率没有差异。在性别间和物种间进行比较时，短期（1年）生长和繁殖力对长期生长或死亡率没有一致的影响模式。大小对一个物种的生长有显著（但较小）影响，对两个物种的死亡率有显著影响。土壤类型对一个物种的死亡率有影响，但对所有三个物种的生长都有影响。性别和大小并非始终是预测成年树木表现的有力依据。
