虽然种群遗传多样性在物种保护中有广泛的应用，但没有研究探讨这种多样性在社区一级的后果。我们表明，人口的遗传多样性（种间杂交）在一个占主导地位的河岸树影响节肢动物群落组成的207种。在一个实验园中，植物杂交类型构建了个体树木的节肢动物群落，在野生林分中，植物遗传多样性占节肢动物多样性变异的近60%。虽然以前的实验花园的研究已经证明了植物基因型对节肢动物群落的影响，我们的研究将这些发现从实验花园中的个体树木扩展到植物种群遗传多样性是构建节肢动物多样性的重要因素的三角叶杨的自然林分。这些研究结果表明，在一个优势物种的遗传多样性的保护是远远超过以前认识到的重要，可能是特别重要的杂交系统。
While population genetic diversity has broad application in species conservation, no studies have examined the community-level consequences of this diversity. We show that population genetic diversity (generated by interspecific hybridization) in a dominant riparian tree affects an arthropod community composed of 207 species. In an experimental garden, plant cross type structured the arthropod community of individual trees, and among stands in the wild, plant genetic diversity accounted for nearly 60% of the variation in arthropod diversity. While previous experimental garden studies have demonstrated the effects of plant genotype on arthropod communities, our study extends these findings from individual trees in an experimental garden to natural stands of cottonwoods where plant population genetic diversity was a significant factor structuring arthropod diversity. These findings argue that the preservation of genetic diversity in a dominant species is far more important than previously realized, and may be particularly important in hybridizing systems.
