Knowledge graph centered on Hierarchical leaf trait sampling in aspen clones (Salicaceae) with 29 nodes and 105 connections. Top connected: Rocky Mountain Biological Laboratory, Gothic, Engelmann Spruce, Populus tremuloides, Populus.
Hierarchical sampling design with nested random effects (site, plot, tree, branch) to assess intraspecific trait variation while accounting for clonal structure. Multiple leaves collected per branch to capture within-tree variation.
