The structure of the community of moss springtails on oak and fir bark in the forests at the NW slope of Iztaccihuatl Volcano, State of Mexico, is analyzed. The study included four samplings (November 2003, March-June-August 2004), carried out in three altitudes I: 2750 m, II: 2 930 and 3 250 m a.s.l. Calculated indexes were: species richness (S), Shannon's diversity index (H'), Pielou's evenness index (J') and Simpson dominance (lamda). An ANOVA of two way test was used to evaluate the effect of altitude and sampling date on the total density of the springtails. The total number of species was 24 (altitude I=17, altitude II=14, altitude III=13). The greatest density was at altitude III and the highest species richness at altitude I. Americabrya arida and Willowsia mexicana were dominant. There is a positive significant effect of altitude on their density. The highest Sörensen similarity between communities was 59% (altitudes II and III).
对墨西哥州伊兹塔西瓦特尔火山北坡森林中橡树和冷杉树皮上的苔藓跳虫群落结构进行了分析。该研究包括四次采样（2003年11月、2004年3月 - 6月 - 8月），在三个海拔高度进行：I：2750米，II：2930米和III：3250米（海拔高度）。计算的指标有：物种丰富度（S）、香农多样性指数（H'）、皮洛均匀度指数（J'）和辛普森优势度（λ）。采用双向方差分析来评估海拔高度和采样日期对跳虫总密度的影响。物种总数为24种（海拔I = 17种，海拔II = 14种，海拔III = 13种）。密度最大的是在海拔III处，物种丰富度最高的是在海拔I处。干旱美洲藓和墨西哥维罗氏藓占主导地位。海拔对它们的密度有显著的正向影响。群落之间最高的索伦森相似度为59%（海拔II和III）。
