Hi Tom,
I might like to know if my general view of uptake pathways is right:
From report 4/05 I've learned that about half of all SAMs are capable of using HCO3-. There are only very few plants which need CO2 for survival since they can't uptake HCO3- at all, e.g. Tonina sp., Neaea sp., Eriocaulon setaceum etc. On the other hand there are plants like Anacharis, Ceratophyllum, Egeria, Najas, Vallisneria which can exist from HCO3- exclusively without any free CO2 in the water column. But all plants prefer CO2 over HCO3- and, if capable, start taking in HCO3- when CO2 gets low/deficient.
Anything wrong with this or would you concur?
Regards,
Detlef
