Competing Interests
The authors have read the journal’s policy and have noted the potential conflict of interest arising from one of the co-authors, Yolande Steenkamp, being affiliated with the South African National Biodiversity Institute, which can be viewed as a commercial company. However, this institute did not fund the study or otherwise influence the study, and does not gain financially from the results or the publication. Further, this affiliation does not alter the authors’ adherence to all the PLoS ONE policies on sharing data and materials.
