Vital Stain Results
Note: the CMFDA stain technique commonly underestimates the abundance of live
organisms in this size class because not all live organisms reliably take up this stain.

Total Counts
This approach commonly overestimates the abundances of live organisms in this size
class because all individuals in fixed samples are counted unless obviously dead (significant
damage to organism).
