系统地理学和景观遗传学是近30年来兴起的。系统地理学是种群遗传学和系统学之间的桥梁，景观遗传学是景观生态学和种群遗传学之间的桥梁。这两个领域可以被认为是简单的融合了经典的遗传学和基因组学，但是，它们在时间，空间和生物体的规模和所使用的方法不同。我开始简要总结每个领域的历史和范围，并建议，即使景观遗传学是一个年轻的领域（2003年创造）比地理学（1987年创造），早期的研究由Dobzhansky的“微地理种族”的Linanthus parryae在莫哈韦沙漠的加州和果蝇pseudobscura在美国西部的领域超过40年。理论，模型和方法的最新进展使研究人员能够更好地综合生态和进化过程，以回答生物学中一些最基本的问题。我强调了一些这些新的研究，并强调三个主要领域成熟的调查，利用空间明确的基因组规模的数据：物种形成，谱系分歧和物种界定，并通过时间和空间的适应性理解。需要研究的领域的例子突出显示，最后，我主张在更广泛的领域：植物地理学下的植物地理学和景观遗传学的联盟。
Phylogeography and landscape genetics have arisen within the past 30 y. Phylogeography is said to be the bridge between population genetics and systematics, and landscape genetics the bridge between landscape ecology and population genetics. Both fields can be considered as simply the amalgamation of classic biogeography with genetics and genomics; however, they differ in the temporal, spatial, and organismal scales addressed and the methodology used. I begin by briefly summarizing the history and purview of each field and suggest that, even though landscape genetics is a younger field (coined in 2003) than phylogeography (coined in 1987), early studies by Dobzhansky on the “microgeographic races” of Linanthus parryae in the Mojave Desert of California and Drosophila pseudoobscura across the western United States presaged the fields by over 40 y. Recent advances in theory, models, and methods have allowed researchers to better synthesize ecological and evolutionary processes in their quest to answer some of the most basic questions in biology. I highlight a few of these novel studies and emphasize three major areas ripe for investigation using spatially explicit genomic-scale data: the biogeography of speciation, lineage divergence and species delimitation, and understanding adaptation through time and space. Examples of areas in need of study are highlighted, and I end by advocating a union of phylogeography and landscape genetics under the more general field: biogeography.
