Sawfly diversity along an altitude gradient in Mao er Mountain of Guangxi;

Distribution of organic matternitrogen and phosphorus along an altitude gradient and productivity change and their relationships with environmental factors in the Alpine meadow;

Changes of the diversity in plant community along altitude gradient in Dongling Mountain,Beijing,China,were studied in 2000 and 2003.

The paper studys the β-diversity pattern of subalpine meadows in Wutai Mountain with the altitude above sea level by analyzing diversity index in terms of the binary and numerical data,Cody index,Wilson index,Shmida index and Sorenson index,and Bray-Curtis index in term of numerical data.

By observing and analyzing the shooting rhythm of Chimonbambusa hejiangensis that grow at differ-ent altitudes from 400 m to 1200 m, the paper come to the conclusion that at different altitudes there weresignificant or appreciably significant differences not only in the early and late shooting period but also in buddedshoots.
