Large-scale integration of specimens, literature, and database infrastructure in Saxifragales.

Collections have played a central role in enabling the use of comprehensive phylogenetic approaches to test macroevolutionary approaches at global scales. As a complement to field-based work and aggregation of existing data, collections place into reach scales of biodiversity analysis previously inaccessible in evolution and ecology. Efficient informatics approaches to mobilizing available and generated data to build such comprehensive datasets are needed to build global biodiversity assessments.‚Äč We use the Saxifragales (2400 species) as a case study in integrating newly generated collections-based data with floristic literature and online data repositories for a comprehensively sampled approach to biodiversity assessment. We show the use of these data for phylogenetic reconstruction, name reconciliation, phenotype assembly, and niche modeling. We also report patterns of sequencing success from a large set of global collections spanning a century. Using an integrative approach, we show the assembly of a hybrid phylogenomic-sanger supermatrix (72% species-level coverage), a matrix of functional traits derivable from species descriptions (60% matrix completion, 100% of phyogenetic tips represented), and assembled occurrence records (84% tip coverage). We conclude by showcasing comparative applications of these data.
