费氏杨（Populus棉白杨）是美国西南部和墨西哥北方重要的基础树种，具有构建多营养级群落、驱动生态系统进程和通过遗传功能性状变异影响生物多样性的能力。P.在上个世纪，由于地表水改道、非本地物种入侵和最近的气候变化，fremontiicover急剧下降。因此，P. fremontiigallery森林被认为是北美最受威胁的森林类型之一。在本文中，我们统一了四个概念领域的基因生态系统研究有关P。fremontii的生存能力，甚至在当前和未来的环境条件下茁壮成长：（i）在热浪期间与冠层热调节相关的水力功能;（ii）菌根互惠关系到气候变化的弹性和入侵的非本地树木/灌木，柽柳;（iii）表型可塑性作为应对气候快速变化的机制;和（iv）P. fremontii和其他密切相关的Populus物种，其中杂交种的活力增强可能会在环境变化中保持Populus的基础能力。我们还讨论了通过遥感将这些概念领域从基因扩展到生态系统水平的机会。我们预计，这些概念研究领域的探索将促进气候变化的解决方案，被认为是生物多样性保护至关重要的基础物种，并可以作为美国西南部和世界各地干旱地区适应性管理的模式。
Populus fremontii(Fremont cottonwood) is recognized as one of the most important foundation tree species in the southwestern USA and northern Mexico because of its ability to structure communities across multiple trophic levels, drive ecosystem processes and influence biodiversity via genetic-based functional trait variation. However, the areal extent ofP. fremontiicover has declined dramatically over the last century due to the effects of surface water diversions, non-native species invasions and more recently climate change. Consequently,P. fremontiigallery forests are considered amongst the most threatened forest types in North America. In this paper, we unify four conceptual areas of genes to ecosystems research related toP. fremontii’scapacity to survive or even thrive under current and future environmental conditions: (i) hydraulic function related to canopy thermal regulation during heat waves; (ii) mycorrhizal mutualists in relation to resiliency to climate change and invasion by the non-native tree/shrub,Tamarix; (iii) phenotypic plasticity as a mechanism for coping with rapid changes in climate; and (iv) hybridization betweenP. fremontiiand other closely relatedPopulusspecies where enhanced vigour of hybrids may preserve the foundational capacity ofPopulusin the face of environmental change. We also discuss opportunities to scale these conceptual areas from genes to the ecosystem level via remote sensing. We anticipate that the exploration of these conceptual areas of research will facilitate solutions to climate change with a foundation species that is recognized as being critically important for biodiversity conservation and could serve as a model for adaptive management of arid regions in the southwestern USA and around the world.
