Physalis_dilution_study.csv relates to
Appendix S1. Part IV. The relationship between sample concentration and detected compound
richness.

These data are summarized from GC/MS analysis of a single extraction of Physalis angulata
that was run on the instrument at different concentrations. See methods in paper for
details. 

Variable descriptions:

*Concentration.mgperml: Concentration of sample in solvent in mg extract per ml solvent
*PeakNum: Number of peaks detected on GC-MS.



Physalis_diversity_abundance_relationship.csv relates to
Appendix S1. Part V. Exploration of diversity–abundance relationship in​Physalis angulata.

These data are from leaf samples of Physalis angulata that were extracted and extractions
divided into
"D" and "ND" aliquots. The "D" aliquots were differentially diluted prior to HPLC analysis
at a set ratio of extract mass to solvent. The "ND" aliquotes were diluted prior to HPLC
analysis at a set ratio of dry plant mass to solvent. See methods in paper for details. 

Variable descriptions are as follows:  

*ID: Plant ID
*Aliquot.mg: Mass of aliquot in mg of dry weight plant material used in the extraction
*insert.D.mg:  initial mass of "D" vial to be used in differentially diluted extracts
*insert.ND.mg: initial mass of "ND" vial to be used for equally diluted extracts
*insert.D.w.extract: final mass of "D" vial after adding a 100 uL aliquot of extract (of
500uL total extract volume) and evaporating to dryness
*insert.ND.w.extract: final mass of "ND" vial cafter adding a 100 uL aliquot of extract
(of 500uL total extract volume) and evaporating to dryness
*Extract.mass.D.mg: the mass of the extract in the "D" vials (final mass - initial mass) 
*Extract.mass.ND.mg: the mass of the extract in the "ND" vials (final mass - initial mass)
*PeakArea.D: the total peak area in chromatograms from "D" samples
*PeakNum.D: the total number of peaks in chromatograms from "D" samples
*PeakArea.ND: the total peak area in chromatograms from "ND" samples
*Peak.Num.ND: the total number of peaks in chromatograms from "ND" samples
