- •
Cyst/Lycopodium spore ratios between 0.5 and 2.0 are recommended to facilitate counting.
- •
Using powdered sediment and sonicating for more than 5 min is not recommended.
- •
The largest loss of cysts and Lycopodium spores occurs during sieving.
- •
This loss leads to overestimates in calculated cyst concentrations of only ~ 4.8%
