热带森林正以每年超过150 000平方公里的速度被砍伐（Whitmore，1997年），造成现有野生动物生境的大面积丧失和破碎。破碎化对热带生态系统的动态有无数的影响（例如，Laurance & Bierregaard 1997），但它对植物群落的影响只受到有限的关注（例如，Williams-Linera 1990; Laurance 1991，1997; Malcolm 1994; Turner et al. 1996）。我们描述的频率的死亡率和损害的家庭桃金娘科在破碎和连续的亚马逊雨林。通过评估边缘和面积效应以及碎片年龄的相对重要性，我们可以更好地了解最近破碎的森林生态变化的机制。
Tropical forests are being cleared at a rate of over 150,000 km2 per year (Whitmore 1997), causing exten-sive loss and fragmentation of existing wildlife habitats. Fragmentation has myriad impacts on the dynamics of tropical ecosystems (eg, Laurance & Bierregaard 1997) but its effects on plant communities have received only limited attention (eg, Williams-Linera 1990; Laurance 1991, 1997; Malcolm 1994; Turner et al. 1996). We describe the frequency of mortality and damage in trees of the family Myrtaceae in fragmented and continuous Amazonian rainforests. By assessing the relative importance of edge and area effects and fragment age, we can better understand the mechanisms of ecological change in recently fragmented forests.
