Abstract
Benthic, free-living marine nematodes from two stations, one subtidal, one intertidal, in the North Inlet Estuary, South Carolina, USA, have been characterized by measurement of adenosine triphosphate (ATP), carbon, caloric content, and ash-free dry weight. Two methods of extracting the organisms from the sediment were used. Resulting carbon to ATP ratios and population density data from ongoing North Inlet meiofauna studies show that the nematodes account for 0.11 to 6.33 μg ATP per g dry weight of sediment, varying seasonally. The percentage of nematode ATP/g sediment is higher in the winter and lowest in the summer, and accounts for 68% to over 90% of the total sediment ATP. The findings of this study indicate that meiofauna, particularly nematodes, can no longer be overlooked as a separate entity in attempts to partition benthic systems.
