描述了法属圭亚那热带雨林的树冠动态(即树冠空隙的形成和关闭)。研究了林冠空隙的形成。对林隙大小测量的困难进行了研究，并研究了树木倒塌和树枝倒塌的原因和后果。结果表明，林隙位置不是随机的。草皮因素可能会使森林中的一些地区成为干扰热点，而其他地区则较少受到干扰。此外，还讨论了林隙的封闭和林隙中树木的育苗表现。林隙中的补充量在很大程度上取决于林隙形成之前出现的苗木和树苗的偶然出现。讨论了物种的专门化，并得出结论，关于物种微生境可用性(在林隙中)和微生境需求的详细信息可能表明，哪些个体在哪个位置有最高的生存机会。最后，对这些发现在森林实践中的潜在应用进行了研究。
The canopy dynamics (i.e. the formation and closure of canopy gaps) of a tropical rain forest in French Guiana are described. The formation of canopy gaps is investigated. The difficulties with gap size measurements are studied, and causes and consequences of treefalls and branchfalls are examined. It is concluded that canopy gap location is not random. Sod factors may make some areas in the forest hot spots of disturbances, whereas other areas are less frequently disturbed. Furthermore, the closure of canopy gaps and tree seedling performance in gaps are discussed. Recruitment in gaps is largely determined by the fortuitous occurrence of seedlings and sapling that were present before the gap was formed. Specialisation of species is discussed and its concluded that detailed information on micro-habitat availability (in gaps) and on micro-habitat needs of species may indicate which individuals at which location have the highest chance of survival. Finally, the potential application of these findings for application in forest practices are examined.
