Genomic and transcriptomic analyses reveal polygenic architecture for ecologically important traits in aspen ( Michx.).

Intraspecific genetic variation in foundation species such as aspen ( Michx.) shapes their impact on forest structure and function. Identifying genes underlying ecologically important traits is key to understanding that impact.

Growing up aspen: ontogeny and trade-offs shape growth, defence and reproduction in a foundation species.

Background And Aims: Intraspecific variation in foundation species of forest ecosystems can shape community and ecosystem properties, particularly when that variation has a genetic basis. Traits mediating interactions with other species are predicted by simple allocation models to follow ontogenetic patterns that are rarely studied in trees. The aim of this research was to identify the roles of genotype, ontogeny and genotypic trade-offs shaping growth, defence and reproduction in aspen.
