Nitrogenase activity in mangrove forests at two locations in the North Island, New Zealand, was measured by acetylene reduction and N(2) uptake. Nitrogenase activity (C(2)H(2) reduction) in surface sediments 0 to 10 mm deep was highly correlated (r = 0.91, n = 17) with the dry weight of decomposing particulate organic matter in the sediment and was independent of light. The activity was not correlated with the dry weight of roots in the top 10 mm of sediment (r = -0.01, n = 13). Seasonal and… CONTINUE READING
