Data from: Annual Compensation for Floral Herbivory by an Iterocarpic Thistle
Summary:
View help for Summary
We tested the extent to which reproductive effort by an iterocarpic native thistle Cirsium undulatum provided within-season tolerance for insect floral herbivory through plant response to apical damage. We imposed apical damage and used insecticide to reduce herbivory damage to manipulate plant response and potential outcomes in reproductive compensation. Data include: 1) detailed size and fecundity data per plant individual under different treatments; and 2) insect damage score and seeds produced per individual flower head.
