Erratum: Do honey bee (Apis mellifera) foragers recruit their nestmates to native forbs in reconstructed prairie habitats? (PLoS ONE (2020) 15: 2 (e0228169) DOI: 10.1371/journal.pone.0228169)

Abstract

In section 2.6.3 of the Materials and methods, there is an error in the estimated relationship between waggle run duration and distance advertised, taken from a linear regression of the combined calibration datasets collected during this study and a previous study (Schürch et al. 2013). The correct estimated relationship is: D = 809.4d – 206.5. This discrepancy was due to an error in copying the coefficients, which then caused the converted slope to be 14.3 m higher and the intercept to be 20.1 m lower than they should have been. Due to the error, there are also errors in the third and fourth paragraphs of section 3.1 of the Results. The correct paragraphs are: We also compared the average distances of advertised nectar sources across the foraging season. At Belwin Conservancy, dancers advertised nectar sources that were an average of 953.86±33.14 meters (mean±SEM) away from the hive, with a maximum advertised distance of 4,805.06 meters. However, there was a significant decrease across the season from an average of 1,126.26±61.16 in May and June to an average of 717.07±48.76 in August and September (F(2,398) = 13.83, p<0.0001; Figure 4). At Carleton College, the average distance of advertised nectar sources was 806.91±29.02 and did not change significantly across the season (F(2,493) = 0.37, p = 0.69). The averages and trends for dances advertising pollen sources were very similar to those for nectar sources. Pollen dances at Belwin Conservancy advertised sources at an average distance of 927.40±40.13 meters with a significant seasonal decrease from May to August (F(2,220) = 5.79, p<0.01). Pollen dances at Carleton College advertised an average distance of 797.83 ±26.47 meters with no significant seasonal change (F(2,405) = 0.89, p = 0.41).
