"From 2009 to 2022, we conducted a series of field surveys in South China and collected a number of specimens of the Calotes versicolor species complex, and found that the population of what we thought was Calotes versicolor in South China and Northern Vietnam was a new undescribed species and two subspecies," says Yong Huang, whose team described the new species. Wang's garden lizard (Calotes wangi) is less than 9 cm long, and one of its distinguishing features is its orange tongue.

The protocol employs a streamlined extraction from a single sample, which reduces variation, improves efficiency, preserves data fidelity and maximizes use of precious biospecimens. "Our new technique enables researchers to study metabolic phenotypes in a unique way while getting the most information we can out of single samples," said Ryan Sheldon, Ph.D., director of VAI's Mass Spectrometry Core.
