This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal). This article has been retracted at the request of the Editor-in-Chief. Following receipt of a whistle-blower complaint, an investigation of this paper was conducted. The Editor-in-Chief no longer has confidence in the scientific integrity of this paper. The paper exhibits evidence of authorship manipulation. Seven co-authors were added to the paper during the review and revision process, in contravention of the journal policies on authorship changes. One of these has indicated to the Editor-in-Chief that they were entirely unaware of having been listed as a co-author [this author does not appear in the published version of the paper having indicated to the publisher that they were not a co-author in advance of publication]. In the course of the investigation two issues of potential data manipulation were also identified. When raw data was requested from the corresponding author, of the initial submission [not the corresponding author listed in the published version, but still a co-author] curated data was provided. The metadata on the curated data predates the reported conduct of the study by five years. Photos of test specimens provided as ‘proof’ the study was conducted were clearly of different dimension than those reported in the paper. The corresponding author of the published paper is unable to provide more clarifying information and has indicated agreement with this retraction.
