In the published article, there was an error in Figure 5 as published. An error was made when calculating pollen accumulation rate (PAR). The R package “rbacon” was used to create the age–depth model and extract the sediment accumulation rate or deposition time. By default, the argument “cmyr” is set to FALSE and sediment accumulation rates are calculated in years per cm. To obtain the sediment accumulation rate, the cmyr argument must be set to TRUE. Due to the wording in the manual, we thought that the sediment accumulation rate was extracted, but deposition time was extracted. In the paper, we used the incorrect formula to calculate PAR given that we extracted the deposition time and not the sediment accumulation rate. In the correction, we used . The corrected Figure 5 and its caption appear below.
Figure 5. Pollen accumulation rate (×10 grains/cm2/year) of the most common non-aquatic taxa present at Arnold’s Pond, classified by pollen zone.
In the published article, there was an error in Figure 6 as published. Several pollen concentration values were incorrect due to the volume not being standardized to 1 cm3. An error was also made when calculating pollen accumulation rate (PAR). The R package “rbacon” was used to create the age–depth model and extract the sediment accumulation rate or deposition time. By default, the argument “cmyr” is set to FALSE and sediment accumulation rates are calculated in years per cm. To obtain the sediment accumulation rate, the cmyr argument must be set to TRUE. Due to the wording in the manual, we thought that the sediment accumulation rate was extracted, but deposition time was extracted. In the paper, we used the incorrect formula to calculate PAR given that we extracted the deposition time and not the sediment accumulation rate. In the correction, we used . The corrected Figure 6 and its caption appear below.
Figure 6. (a) Percentage of Betula spp. grains originating from trees and shrubs, (b) Pollen accumulation rate (×102 grains/cm2/year), (c) Pollen concentration (×103 grains/cm3) for Arnold’s Pond, classified by pollen zone.
A correction has been made to Discussion, Influence of vegetation on the fire regime, paragraph 3. This sentence previously stated:
“The fire-facilitated Picea was also likely in low density stands for much of zone 2, as the average pollen influx of ~1,750 grains/cm2/year was lower than the average Picea influx of pollen zone 4b where a closed canopy was likely present (~3,100 grains/cm2/year) (Figure 6b).”
The corrected sentence appears below:
“The fire-facilitated Picea was also likely in low density stands for much of zone 2, as the average pollen influx of ~1,900 grains/cm2/year was lower than the average Picea influx of pollen zone 4b where a closed canopy was likely present (~4,800 grains/cm2/year) (Figure 6b)”.
A correction has been made to the Acknowledgments. This sentence previously stated:
“We would like to thank K. Costanza, D. Łucówand J.M. St-Jacques for constructive comments used to improve the manuscript. We would also like to thank R. Skinner and K. Gaudet for their aid in the field and lab. The contents of this manuscript build upon the thesis of NL.”
The corrected sentence appears below:
“AA as the principal investigator received a Parks Canada Research and Collection Permit to sample within Terra Nova National Park (Permit Number: TNP-2017-25138). We would like to thank K. Costanza, D. Łucówand J.M. St-Jacques for constructive comments used to improve the manuscript. We would also like to thank R. Skinner and K. Gaudet for their aid in the field and lab. The contents of this manuscript build upon the thesis of NL.”
The original article has been updated.
