亚马逊有一个非常高的，虽然还不完全知道，物种多样性分布在马赛克的异质栖息地，也很差的特点。由于这种多方面的复杂性，亚马逊河流域对地理基因组学方法提出了巨大的挑战，这些方法试图找到地球地质历史和生物多样性之间的因果关系，包括使用基因组数据来解决地质问题。这一挑战甚至更大，因为需要跨学科的方法，尽管跨学科工作的困难，在不同的研究领域的文献的误解可能会产生不切实际的生物-地质联系的情况。地质学家和生物学家的信息交流和联合工作对于建立更有力和更现实的假设至关重要，这些假设涉及过去的气候如何影响种群之间的分布和连通性，排水网络的演变如何影响生物多样性，以及生态特征和物种相互作用目前如何定义生物多样性的空间组织，以及这个组织在过去和未来的变化。亚马逊河流域的异质性以及历史进程对其不同区域和生态系统的不同影响必须在地理学、保护和决策中得到更全面的认识。从这个角度来看，我们提供的例子，地质，气候和生态信息相关的生物多样性在亚马逊河流域的研究，最近的进展（及其局限性）可能是不明显的研究人员在其他领域。这三个例子包括气候模式输出的局限性、河流水系的复杂演变以及物种与其生境之间受生态专门化影响的复杂联系，它们是一个小样本，旨在说明采取更综合的跨学科方法的紧迫性。
Amazonia has a very high, although still incompletely known, species diversity distributed over a mosaic of heterogeneous habitats that are also poorly characterized. As a result of this multi‐faceted complexity, Amazonia poses a great challenge to geogenomic approaches that strive to find causal links between Earth's geological history and biotic diversification, including the use of genomic data to solve geologic problems. This challenge is even greater because of the need for interdisciplinary approaches despite the difficulties of working across disciplines, where misinterpretations of the literature in disparate research fields can produce unrealistic scenarios of biotic‐geologic linkages. The exchange of information and the joint work of geologists and biologists are essential for building stronger and more realistic hypotheses about how past climate may have affected the distribution and connectivity among populations, how the evolution of drainage networks influenced biotic diversification, and how ecological traits and species interactions currently define the spatial organization of biodiversity, and thus how this organization has changed in the past and may change in the future. The heterogeneity of Amazonia and the different effects of historical processes over its distinct regions and ecosystems have to be more completely recognized in biogeography, conservation; and policymaking. In this perspective, we provide examples of geological, climatological; and ecological information relevant to studies of biotic diversification in Amazonia, where recent advances (and their limitations) may not be apparent to researchers in other fields. The three examples, which include the limitations of climate model outputs, the complicated evolution of river drainages; and the complex link between species and their habitats modulated by ecological specialization, are a small subsample intended to illustrate the urgency for more integrated interdisciplinary approaches.
