Abstract

Mass loss and changes in the microarthropod assembleges were monitored in six types of decomposing surface leaf-litter confined in mesh-bags and set across a Chihuahuan Desert watershed for 17 months. High initial mass losses were observed in all litter types. Except for black grama grass litter, mass loss trends were described by the double exponential decay model............................The study supported the idea that depth and stability of the surface litter determine the size of the microarthropod community. The data did not provide clear evidence of the role played by the microarthropod fauna on surface litter breakdown.
