Comment:
Species abundance: V = very abundant (100+ specimens per field of view), A = abundant (11 to 100 specimens per field of view), C = common (1 to 10 specimens per field of view), F = few (1 specimen per 2 to 10 fields of view), R = rare (1 specimen per 50 fields of view), P = present (1 specimen 50 or more fields of view), lowercase letters = reworked.
