title: Data from: The impact of plant genetic variation, drought, and leaf nitrogen on plant-herbivore interactions

description: Plant genotype, drought stress, and their interaction are among the
 factors contributing to the susceptibility of plants to herbivory. The
 plant's nitrogen concentration, a critical and often limiting
 nutrient, differs with plant genotype and drought. Still, few studies have
 investigated the impact of the interaction of genotype and drought on
 herbivory and plant nitrogen. We established a common garden in
 Duluth, MN, of tall goldenrod, Solidago altissima, collected from a local
 Minnesota site to analyze the effects of goldenrod genotype and drought
 stress on leaf nitrogen and the preference and performance of the
 chrysanthemum lace bug, Corythucha marmorata. Lace bugs had
 oviposition, nymph, and adult preferences among host plant genotypes,
 water treatments, and among genotype and water treatment combinations.
 Nymph and adult survival and adult mass varied significantly due to plant
 genotype, water treatment, the interaction of plant and water treatment,
 and the interaction of treatment with lace bug density. Oviposition
 preference and offspring performance were significantly positively
 related. Leaf nitrogen increased with the increasing severity of
 the water limitation in the absence of lace bugs. However, in the presence
 of lace bugs, there was no difference in nitrogen among water treatments.

 ## DESCRIPTION OF THE DATA AND FILE STRUCTURE
 ChoiceandNoChoiceExperiments.csv dataset was used to determine lace bug
 preference and performance among plant genotypes and water treatments in
 the choice and no choice experiments Variable List * Experiment:
 experimental treatment based on whether insects had a choice to colonize
 plants * Genotype: unique identifier for the individual plant genotype,
 randomly labeled with a letter between A-T * Water Treatment: low,
 moderate, or high-water treatment assigned to plant * Adult Abundance: the
 number of lace bug adults * Nymph Abundance: the number of lace bug nymphs
 * Egg Number: the number of lace bug eggs * S.Leaves (%): the percentage
 of senescing leaves on the plant replicate Missing data codes: NA

 genotypes and water treatments in the no choice experiments Variable List
 * Genotype: unique identifier for the individual plant genotype, randomly
 labeled with a letter between A-T * Water Treatment: low, moderate, or
 high-water treatment assigned to plant * Sex: lace bug sex * Mass(µg):
