Abstract
Floating and attached cyanobacterial mats are a permanent feature of the nearshore marine environment at La Parguera, Puerto Rico. Nitrogenase activity exhibited a diel cycle with daytime inhibition and enhanced nocturnal activity. Nitrogenase activity in M. lyngbyaceus mats is closely regulated by concentrations of NH4 + and NO3 - within the range of values common to their environment. The opportunistic strategy of N utilization used by M. lyngbyaceus, whereby molecular N is primarily consumed only in the absence of significant concentrations of alternate inorganic N sources, assures the success of these communities. -from Authors
