Species abundances: S = single (<0.1 %), R = rare (0.1-1 %), F = frequent (1-10 %), C = common (10-30 %), A = abundant (30-50%), D = dominant (>50 %), - = not present.

物种丰度分级标准:S = 零星(single,<0.1%),R = 稀有(rare,0.1%~1%),F = 频现(frequent,1%~10%),C = 常见(common,10%~30%),A = 丰富(abundant,30%~50%),D = 优势(dominant,>50%),- = 未检出(not present)。
