Effects of Temperature on Calcium Uptake in BOSSIELLA ORBIGNIANA ORBIGNIANA

<p>The effect of temperature on calcification in <em>Bossiena orbigniana orbigniana</em> (Decaisne, 1842) [Manza, 1940; Silva, 1957] (Corallinaceae) was studied using calcium-45 labeling of terminal segments under laboratory conditions. <em>B. orbigniana</em> has optimum calcium uptake for the temperatures 17-21°C within a temperature range of 3-37°C. These results suggest that optimum calcification in <em>B. orbigniana</em> should take place from late spring to early autumn. Q₁₀values for 3-21°C averaged 3.39 indicating an enzyme-governed reaction. It is proposed that thallus growth rate and calcification are not directly related. It is believed that the optimum temperatures (17-21°C) affect the enzymes towards an increase in the rate of calcification and perhaps the rates of photosynthesis and respiration.</p>
