使用聚类方法分析了在3个欧洲国家收集的果蝇物种之间的关联。由此产生的树状图相结合，以给出一个计划的协会所示的所有3个调查。这些一般群体是根据已知的果蝇繁殖地来解释的。一个生态组，真菌繁殖物种进行了详细的研究，并调查了它们的地理关联模式。采集量最大的3个种是D. transversa，D. phalerata和D.在西欧，喀麦隆似乎在南北方向上相互取代。生态边缘区可以用一个物种在其生态群中的出现频率来定义。
The associations shown between species of Drosophila collected in 3 European countries are analyzed using a clustering method. The resulting dendrograms are combined to give a plan of associations shown by all 3 surveys. These general groups are interpreted in the light of what is known about Drosophila breeding sites. One ecological group, the fungal breeding species are examined in detail and their pattern of geographical associations investigated. The 3 most abundant species in collections, D. transversa, D. phalerata and D. cameraria appear to replace one another in a north-south direction in western Europe. Ecologically marginal areas may be defined using the frequency of a species within its ecological group.
