The hypothesis to be tested is that blue-green algae (Cyanobacteria) will in general be found to be more efficient in using CO2 than will most non blue-green algae, thus leading to blue-green dominance when pH is high and CO2 is low. The hypothesis will be tested during a whole growing season in two lakes using + and - enrichments with CO2 by changing pH. The experiments will be evaluated by measuring CO2 uptake with 14C microautoradiography.

有待验证的假设是蓝绿藻 （蓝细菌）通常会被发现在 比大多数非蓝绿藻使用二氧化碳，从而导致 当pH高而CO2低时，蓝绿色占优势。 的 假设将在整个生长季节在两个测试 湖泊使用+和-富集与CO2通过改变pH值。 实验将通过用14 C测量CO2吸收来评估 显微放射自显影术
