  abstract = {{B}iological nitrogen fixation ({BNF}) isa fundamental part of nitrogen cycling in tropical forests, yet little is known about the contribution made by free-living nitrogen fixers inhabiting the often-extensive forest canopy. {W}e used the acetylene reduction assay, calibrated with {N}-15(2), to measure free-living {BNF} on forest canopy leaves, vascular epiphytes, bryophytes and canopy soil, as well as on the forest floor in leaf litter and soil. {W}e used a combination of calculated and published component densities to upscale free-living {BNF} rates to the forest level. {W}e found that bryophytes and leaves situated in the canopy in particular displayed high mass-based rates of freeliving {BNF}. {A}dditionally, we calculated that nearly 2 kg of nitrogen enters the forest ecosystem through free-living {BNF} every year, 40% of which was fixed by the various canopy components. {O}ur results reveal that in the studied tropical lowland forest a large part of the nitrogen input through free-living {BNF} stems from the canopy, but also that the total nitrogen inputs by free-living {BNF} are lower than previously thought and comparable to the inputs of reactive nitrogen by atmospheric deposition.},
