在热带森林中，关于保持树种高度多样性的争论集中在树木凋落林隙作为主要干扰源的作用上。利用1988年飓风琼袭击尼加拉瓜加勒比海岸以来积累的10年数据系列，我们研究了物种积累随时间推移和增加个体采样的模式。我们的分析表明，飓风后的模式不同于一个简单的树木倒下的干扰后的模式，我们的结论是，先锋有限的大扰动，因此不抑制其他物种的方式，他们在较小的干扰。
The debate over the maintenance of high diversity of tree species in tropical forests centers on the role of tree-fall gaps as a primary source of disturbance. Using a 10-year data series accumulated since Hurricane Joan struck the Caribbean coast of Nicaragua in 1988, we examined the pattern of species accumulation over time and with increased sampling of individuals. Our analysis shows that the pattern after a hurricane differs from the pattern after a simple tree-fall disturbance, and we conclude that pioneers are limited in large disturbances and thus do not suppress other species the way they do in smaller disturbances.
