Abstract
Samples of bark without visible lichen or moss cover were taken from a Juglans nigra located in a city lot in Des Moines, Iowa, remote from water. Euglypha ciliata, E. cuspidata, Microchlamys patella, Centropyxis aerophilus, and two unidentified species of Difflugia were found, ranging from ground level to heights of 35 feet. An estimate of population density, based on a modification of the most probable number count, showed evidence of zonation on the tree surface, with C. aerophilus restricted to near ground level, M. patella occurring approximately evenly up to 35 feet, and E. cuspidata most abundant at moderate heights. Some of the factors related to distribution on the tree surface are discussed.
