The island species–area relationship (ISAR) quantifies how the number of species increases as the area of an island or island-like habitat gets larger and is one of the most general patterns in ecology. However, studies that measure the ISAR often confound variation in sampling methodology and analyses, precluding appropriate syntheses of its underlying mechanisms. Most ISAR studies use only presence–absence data at the whole-island scale, whereas we planned to use a framework that applies individual-based rarefaction to synthesize whether and how the ISAR differs from the null expectation of the passive sampling hypothesis.

综合表明，岛屿物种-面积关系是从被动采样之外的过程中产生的

岛屿物种-面积关系 (ISAR) 量化了物种数量如何随着岛屿或岛状栖息地的面积变大而增加，并且是生态学中最普遍的模式之一。然而，测量 ISAR 的研究通常会混淆采样方法和分析中的变化，从而无法对其潜在机制进行适当的综合。大多数 ISAR 研究仅使用全岛尺度的存在-不存在数据，而我们计划使用一个框架，该框架应用基于个体的稀疏性来综合 ISAR 是否以及如何与被动抽样假设的零期望不同。
