Experimental exposure to elevated CO2 demonstrates that understory trees in the Amazon initially increase their carbon uptake and growth, though this long-term capacity is ultimately constrained by soil nutrient availability.

Amazon understory forests show short-term boost in CO₂ uptake – but this comes at a cost

Experimental increases in CO₂ stimulated plant growth are facilitated by re-distributed root systems to extract nutrient resources more efficiently

💧 Aggressive groundwater and the long memory of contamination

Even after more than a decade of monitoring, the groundwater in this carbonate aquifer remains undersaturated with respect to calcite — consistently showing negative SI values across nearly all observation wells.

This means that the system is still chemically aggressive toward limestone, slowly dissolving the host rock.
The impoundment, operating since 1976, continues to influence the aquifer — with the geometry of possible subsurface voids still uncertain to this day.
