Nonmetric multidimensional scaling analysis. In the map, the abbreviations are formulated as season_location tag number (for example, S_T36 is the sample collected from the coral tagged as number 36 from Tiaoshi in the summer). The parameters in plotting the map were 25 for restarts, 0.01 for minimum stress, and Kruskal fit scheme set 1. 2D Stress, two-dimensional stress.
