Abstract

177 Hurricane Disturbance and Tropical Tree Species Diversity. 2000. Vandermeer, J., Dept. of Biotogy, University of Michigan, Ann Arbor, MI 48109, jvander@umich.edu; I. Granzow de la Cerda, D. Boucher, I. Perfecto, and Javier J. Ruiz. Science 290(5492):788-791. The so-called intermediate disturbance hypothesis states that very large or small disturbances in tropical forests will not prevent suppression of a tree species--that only intermediate disturbances, such as tree-fall gaps, have this effect. To test this hypothesis, the authors examined whether large disturbances also suppress species. They used studies of post-hurricane forest succession that began in February 1989 to examine the pattern of species accumulation on the Caribbean coast of Nicaragua after the large disturbance caused by Hurricane Joan in 1988. Their analysis shows that the pattern after a hurricane differs from that after a single tree-fall disturbance. They conclude that pioneer trees do not respond well after large disturbances and do not suppress other species like they do following smaller disturbances.

177飓风扰动与热带树种多样性。2000年,Vandermeer,J.,密歇根大学生物系,密歇根州安娜堡48109,jvander@umich.edu;I.Granzow de la Cerda、D.Boucher、I.Perfecto和Javier J.Ruiz。《科学》290(5492):788-791。所谓的中间干扰假说指出,热带森林中非常大或很小的干扰不会阻止对一个树种的抑制——只有中间干扰,如树木坠落间隙,才会产生这种影响。为了验证这一假设,作者研究了大型扰动是否也会抑制物种。他们利用1989年2月开始的飓风后森林演替研究,研究了1988年飓风琼造成的大规模扰动后尼加拉瓜加勒比海海岸的物种积累模式。他们的分析表明,飓风过后的模式与单一树木坠落扰动后的模式不同。他们得出的结论是,先锋树在大扰动后反应不佳,也不会像在小扰动后那样抑制其他物种。

期刊介绍: Ecological Restoration is a forum for people advancing the science and practice of restoration ecology. It features the technical and biological aspects of restoring landscapes, as well as collaborations between restorationists and the design professions, land-use policy, the role of education, and more. This quarterly publication includes peer-reviewed science articles, perspectives and notes, book reviews, abstracts of restoration ecology progress published elsewhere, and announcements of scientific and professional meetings.
