Figure from McMurdo Dry Valleys LTER: Phosphorus deficiency and alkaline phosphatase activity in lakes of Taylor Valley, Antarctica

Return to the article from which this figure is taken.

Figure 2. Substrate response of alkaline phosphatase (APase) activity at 5 meters in Lake Bonney (east lobe), with single data point from 5 meters in Lake Hoare for comparison. Incubations were carried out in the dark at a temperature near that in situ (4-5C). APase activity is estimated by the rate of hydrolysis of the MUP substrate analog.
