“…To quantify the contribution of potential water sources of plants, a variety of mixing models were developed, such as IsoSource, SIAR, and MixSIR (Moore & Semmens, 2008;Parnell et al, 2013;Phillips & Gregg, 2003;Phillips, Newsome, & Gregg, 2005;Wu, Liu, & Chen, 2016a;Wu, Liu, & Chen, 2016b). In the recent years, a new Bayesian mixing model of MixSIAR was applied to calculate the relative waterabsorbing proportions of potential sources (Ma & Song, 2016;Wu, Liu, & Chen, 2017). This model incorporates uncertainty in source means/variances, and the ranges of solutions can be interpreted as probabilities, which combine the advantages of SIAR and MixSIR .…”
