Expression of Concern: Environ Earth Sci (2016) 75:246

The Editors-in-Chief of Environmental Earth Sciences are issuing an editorial expression of concern to alert readers that the original article shows substantial indication of irregularities in authorship during the submission process. The authors suggested peer reviewers whose identity was not possible to verify. This article contains overlap with Piri et al. (2015) and Valian et al. (2013) (amongst others). All authors disagree with this editorial expression of concern.
