FIG. 1.
(A) Diel changes in air temperature and relative humidity above decomposing J. effusus during field studies conducted on 7 and 8 September 1994. (B) Diel changes in water potential of J. effusus plant litter. (C) Rates of CO2 evolution. (D) Total polyol and trehalose concentrations extracted from plant litter. The relative humidity data are from single measurements; all other data are means ± standard errors (n = 3). The solid horizontal bar in panel D indicates nighttime, and the cross-hatched horizontal bars indicate daytime. OM, organic matter.
