Abstract

Small, fragmented plant populations with low genetic diversity are susceptible to deterministic and stochastic events that can affect long-term persistence of species. Penstemon lemhiensis Keck (Plantaginaceae) is a rare endemic with small, scattered populations across Idaho and Montana threatened by cumulative impacts of biological invasion, drought, and altered fire regimes. When contextualized by an understanding of rangewide distributions under different environmental change scenarios, conservation genetics can be leveraged to motivate proactive conservation action among collaborating stakeholder groups. We applied a genotypingby- sequencing (GBS) approach across eight populations and 93 individuals of P. lemhiensis. Genetic differentiation among populations followed an isolation-by-distance pattern and ranged from low to moderate (FST = 0.095-0.280). Values of inbreeding were low, and often negative (FIS = -0.039-0.032), indicating outbreeding within populations. Population structure analyses identified six ancestral populations and admixture across all individuals. We contextualized these findings by fitting bioclimatic niche models to past, present, and future climate regime scenarios. Habitat connectivity peaked mid-Holocene and nearly disappeared in the future scenario. Genetic analyses and species distribution models indicated that the species may experience drastic range contraction and accelerated isolation and inbreeding in future. We identified a core area in the Upper Big Hole Valley, Montana most likely to persist as suitable habitat. The National Park Service, Bureau of Land Management, and US Forest Service were identified as key stakeholders in that valley. We outline a proactive collaborative conservation strategy that aim to maintain wild P. lemhiensis populations.

保护基因组学和物种分布模型激励快速变化时代的主动和协作保护
遗传多样性低的小而分散的植物种群容易受到确定性和随机事件的影响,这些事件可能影响物种的长期持久性。车前草(Penstemon lemhiensis Keck)是一种罕见的地方性植物,在爱达荷州和蒙大拿州分布着小而分散的种群,受到生物入侵、干旱和改变的火灾制度的累积影响。在了解不同环境变化情景下的大范围分布的背景下,保护遗传学可以用来激励合作的利益相关者群体采取积极的保护行动。我们对8个种群和93个lemhiensis个体采用了基因分型测序(GBS)方法。群体间的遗传分化遵循距离隔离模式,FST = 0.095 ~ 0.280,范围从低到中等。近交值较低,且常为负值(FIS = -0.039 ~ 0.032),表明种群内有近交。种群结构分析确定了6个祖先种群和所有个体的混合种群。通过将生物气候生态位模型拟合到过去、现在和未来的气候情景中,我们将这些发现置于背景中。栖息地连通性在全新世中期达到峰值,在未来情景中几乎消失。遗传分析和物种分布模型表明,该物种未来可能经历剧烈的范围缩小和加速的隔离和近交。我们在蒙大拿州的上大洞谷确定了一个核心区,最有可能成为合适的栖息地。国家公园管理局、土地管理局和美国林务局被确定为该山谷的主要利益相关者。我们概述了一个积极主动的合作保护策略,旨在维持野生lemhiensis种群。
