Poster sessions are particularly prominent at academic conferences. Posters are usually one frame of a powerpoint (or similar) presentation and are represented at full resolution to make them zoomable.
This study includes genotypic, phenotypic and environmental data for 869 unrelated Populus trichocarpa (black cottonwood) trees that have a natural distribution range in the western United States (northern California to Northern British Columbia). Whole genome re-sequencing data for 869 trees with 11.1 million SNPs were integrated with phenotype and environmental data using genotype-environment association (GEA) and redundancy analysis (RDA) methods to test for the evidence of local adaptation.
