WebHowever, given the large pool of CO 2 in the atmosphere, algal yield in these lakes will never be carbon-limited, but instead will be phosphorus-limited ( Schindler, 1977). Hence, it is possible for growth rate and yield to be limited by different nutrients or the same nutrient.

WebAug 13, 2014 · The level of carbon limitation ( LC) can then be defined as the reduction in carbon uptake due to low carbon availability: LC = (1− fC )×100%. Accordingly, if CO 2 and bicarbonate are both available in saturating concentrations, LC will be close to 0%. Conversely, if CO 2 and bicarbonate are available only in trace amounts, LC approaches … WebNov 1, 2024 · Little research has been done to examine the role of available carbon in increasing inland freshwater lake productivity, partly because the chemistry of carbon usually results in available C concentrations far in excess of biological demand. However, low alkalinity has been suggested to limit production in aquaculture ponds ( Boyd, 1997 ).
