总结我们简要回顾了目前的方法检测非随机模式的时间重叠的开花和结果曲线。我们讨论了这些方法背后的假设，并提出了一种新的分析方法，使用计算机模拟来测量n明智的，而不是成对的，时间重叠。我们量化观察到的n-明智的重叠不同的程度，从最小可能的n-明智的重叠，并将我们的方法应用到几个数据集来测试的假设，种间竞争的动物游客产生开花曲线的重叠小于预期的机会。我们的分析结果几乎没有支持这一假设，但建议替代标准，物种可能会被选择。
SummaryWe briefly review current methods for detecting nonrandom patterns in the temporal overlap of flowering and fruiting curves. We discuss the assumptions behind these methods and propose a new method of analysis using computer simulations to measure n-wise, rather than pairwise, temporal overlap. We quantify the extent to which observed n-wise overlap differs from minimum possible n-wise overlap and apply our method to several data sets to test the hypothesis that interspecific competition for animal visitors has produced flowering curves whose overlap is less than that expected by chance. Results of our analyses provide little support for this hypothesis but suggest alternate criteria by which the species may be selected.
