“…Thirty-eight papers have been published that either stated that they used the criteria (with no description of how the criteria were used), or used the criteria with a description of how they applied the criteria. At least seven research groups (Kelly et al, 2003;Xavier et al, 2009;Concepcion et al, 2010;Geller et al, 2010;de Araujo Bumbeer and da Rocha, 2012;Campbell et al, 2016;Pociecha et al, 2016) have suggested alterations to the criteria. The alterations being either consideration of whether a species is detected on artificial substrate(s) (Kelly et al, 2003; de Araujo Bumbeer and da Rocha, 2012; Pociecha et al, 2016), or the use of molecular tools (Xavier et al, 2009;Concepcion et al, 2010;Geller et al, 2010).…”
