Simultaneous sampling for microorganisms was accomplished at altitudes of 690, 1,600, and 3,127 meters. The location of temperature inversions in relation to the collection altitude determined, to a great extent, the micropopulation. High micropopulations were found when an inversion was above the sampling altitude, and low populations when the inversion was below the sampling altitude. Diurnal periodicity which could be generally correlated with periods of minimal and maximal convective activity was observed. Evidence is presented showing that the micropopulation is more stable at higher altitudes than at lower altitudes.
在海拔690米、1600米和3127米处同时进行了微生物采样。温度逆温层相对于采样高度的位置在很大程度上决定了微生物种群数量。当逆温层在采样高度之上时,发现微生物种群数量较高;当逆温层在采样高度之下时,种群数量较低。观察到了昼夜周期性,这通常与对流活动的最小和最大时期相关。有证据表明,较高海拔处的微生物种群比较低海拔处更稳定。
