Biodiversity conservation requires conserving evolutionary potential—the capacity for wild populations to adapt. Understanding genetic diversity and evolutionary dynamics is critical for informing conservation decisions that enhance adaptability and persistence under environmental change. We review how emerging landscape genomic methods provide plant conservation programs with insights into evolutionary dynamics, including local adaptation and its environmental drivers. Landscape genomic approaches that explore relationships between genomic variation and environments complement rather than replace established population genomic and common garden approaches for assessing adaptive phenotypic variation, population structure, gene flow, and demography. Collectively, these approaches inform conservation actions, including genetic rescue, maladaptation prediction, and assisted gene flow. The greatest on-the-ground impacts from such studies will be realized when conservation practitioners are actively engaged in research and monitoring. Understanding the evolutionary dynamics shaping the genetic diversity of wild plant populations will inform plant conservation decisions that enhance the adaptability and persistence of species in an uncertain future.

保护进化潜力:将景观基因组学与现有方法相结合,为植物保护提供信息



生物多样性保护需要保护进化潜力——野生种群的适应能力。了解遗传多样性和进化动态对于为保护决策提供信息至关重要,以增强环境变化下的适应性和持久性。我们回顾了新兴的景观基因组方法如何为植物保护计划提供对进化动力学的见解,包括局部适应及其环境驱动因素。探索基因组变异与环境之间关系的景观基因组方法补充而不是取代现有的群体基因组方法和用于评估适应性表型变异、群体结构、基因流和人口统计学的常见花园方法。总的来说,这些方法为保护行动提供信息,包括基因拯救、适应不良预测和辅助基因流。当保护从业者积极参与研究和监测时,此类研究将产生最大的实地影响。了解塑造野生植物种群遗传多样性的进化动力学将为植物保护决策提供信息,从而增强物种在不确定的未来的适应性和持久性。
