Description of the data and file structure

Key for headers in "fieldwork_data.csv" and "herbivory_leaf_data.csv"

Data collected from a common garden field experiment conducted with* Ipomoea purpurea* and the herbicide glyphosate.

Files and variables

File: fieldwork_data.csv

Description: Plant growth and resistance data

Variables

• random: ID number of each plant
• labelID: unique ID (population.maternalline.treatment&block.replicate)
• pop: population
• matid: maternal line number
• pop_mat: unique maternal line identifier (population_maternal line)
• treatment: glyphosate treatment group (ctrl: control group, trtmt: treatment group)
• block: experimental block (1 or 2)
• germDate: germination date (YYYYMMDD; NA - plant did not germinate)
• leafct2: number of leaves on date of second leaf count (NA - no plant)
• herbiv_0719: presence (1) or absence (0) of foliar herbivory on 7/19/2021 (NA - no plant)
• wk2_pct: proportion of leaves showing glyphosate damage 2 weeks post-spray (NA - control group plant; if in treatment group, no plant)
• trtmtdeath: binomial status of treated plants (0 - alive, 1 - dead; NA - control group plant, if in treatment group, no plant)
• pct_herbiv: percentage of leaf tissue missing as estimated from three leaves per plant (NA - no plant)
• hole: proportion of leaves with hole damage present, as estimated from three leaves per plant (NA - no plant)
• margin: proportion of leaves with margin damage present, as estimated from three leaves per plant (NA - no plant)
• surface: proportion of leaves with sueface damage present, as estimated from three leaves per plant (NA - no plant)
• seedct: final seed count done in two complete rounds of collection (NA - no plant)

File: herbivory_leaf_data.csv

Description: herbivory data breakdown by individual leaf

Variables

• date: date photo was taken
• num: plant ID number
• treatment: control vs. treatment group
• area_cm2: area of entire leaf in cm^2 as measured by LeafByte
• missing_cm2: missing area of leaf in cm^2 as measured by LeafByte
• pct_herbiv: percentage of leaf tissue missing as measured by LeafByte
• herbic_dmg: presence (1) or absence (0) of herbicide damage
• browned: presence (1) or absence (0) of browning of leaf tissue
• yellowed: presence (1) or absence (0) of yellowing leaf tissue
• unknown_missing: an unknown area of the leaf has been consumed and is not captured in LeafByte measurements (1) or the leaf was measured normally (0)
• outofbounds: the leaf was outside the boundaries of the scale dots so LeafByte is under-measuring the area (1) or the leaf was measured normally (0)
• DT01-DT143: presence (1) or absence (0) of feeding damage types as defined by Labadiera et al., 2007 (Labandeira CC, Wilf P, Johnson KR, Marsh F. 2007. Guide to Insect (and Other) Damage Types on Compressed Plant Fossils. Version 3.0. Smithsonian Institution.)
  • Hole-feeding DTs: 01-07, 10, 57, 63-64, 78, 126
  • Margin-feeding DTs: 12-15, 26, 143
  • Surface-feeding DTs: 29-30

Code/software

We used the program R (version 4.2.1) to conduct all statistical analyses. Script is included with data.
