Shear Adhesive Performance Of Leaf-Cutting Ant Workers (Atta Cephalotes) (Vol 51, Pg 572, 2019)

In our previous article,Shear adhesive performance of leaf-cutting ant workers(Atta cephalotes), a technical error occurred when calculating shear adhesive performance divided by tarsal pad area of worker ants carrying leaves (Stark, A. Y., Davis, H. R., & Harrison, W. K. (2019). Biotropica, 51(4), 572-580). Shear adhesive performance of worker ants carrying leaves was mistakenly divided by the tarsal pad area of workers riding on leaves. This has slightly changed our results. After correcting for this error, there is now no statistically significant difference in shear adhesive performance divided by tarsal pad area of worker ants riding on leaves and those carrying leaves. Shear adhesive performance of these groups remains statistically different than soldiers, and our original results (shear adhesive performance of all three groups differ from one another) are consistent with the reported trend in the original article using true pad area for each individual (rather than estimated). We list below the pages and figures in the original article that this correction applies to. All authors agree with this change, apologize for their error, and appreciate the opportunity granted by the editors and publisher to make this correction. Our original conclusion, that there is variation in shear adhesive performance per unit area among worker roles ofAtta cephalotes,is still supported by these corrected results.
