Landscape genomics is the modern version of landscape genetics, a discipline that arose approximately 10 years ago as a combination of population genetics, landscape ecology, and spatial statistics. It studies the effects of environmental variables on gene flow and other microevolutionary processes that determine genetic connectivity and variations in populations. In contrast to population genetics, it operates at the level of individual specimens rather than at the level of population samples. Another important difference between landscape genetics and genomics and population genetics is that, in the former, the analysis of gene flow and local adaptations takes quantitative account of landforms and features of the matrix, i.e., hostile spaces that separate species habitats. Landscape genomics is a part of population ecogenomics, which, along with community genomics, is a major part of ecological genomics. One of the principal purposes of landscape genomics is the identification and differentiation of various genome-wide and locus-specific effects. The approaches and computation tools developed for combined analysis of genomic and landscape variables make it possible to detect adaptation-related genome fragments, which facilitates the planning of conservation efforts and the prediction of species' fate in response to expected changes in the environment.
景观基因组学是景观遗传学的现代形式,景观遗传学大约在10年前兴起,是种群遗传学、景观生态学和空间统计学相结合的一门学科。它研究环境变量对基因流动和其他微观进化过程的影响,这些过程决定了种群的遗传连通性和变异。与种群遗传学不同,它在个体样本层面开展研究,而非种群样本层面。景观遗传学与基因组学和种群遗传学的另一个重要区别在于,在景观遗传学中,对基因流动和局部适应性的分析定量考虑了地形和基质特征,即分隔物种栖息地的不利空间。景观基因组学是种群生态基因组学的一部分,种群生态基因组学与群落基因组学一道,构成了生态基因组学的主要部分。景观基因组学的主要目的之一是识别和区分各种全基因组和位点特异性效应。为基因组和景观变量的联合分析而开发的方法和计算工具,使得检测与适应性相关的基因组片段成为可能,这有助于规划保护工作,并预测物种在应对预期环境变化时的命运。
