FIG. 2.
(A) Diel changes in air temperature and relative humidity above decomposing J. effusus during field studies conducted on 14 to 16 June 1994. (B) Diel changes in precipitation and 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 values for precipitation (bars) indicate the amounts accumulated over 1-h periods. The solid horizontal bar in panel D indicates nighttime; and the cross-hatched horizontal bars indicate daytime. OM, organic matter.
