Investigation on population distribution and seasonal change of flies in Yancheng city;

Comparison of population distribution pattern of evergreen broadleaved forests between Nanling Dadingshan Nature Reserve and Dinghushan;

Preliminary investigation of the community structure and population distribution of rotifera in Dongchang Lake;

The distribution population-based genetic algorithm for parameters optimization of two-degree-of-freedom PID controllers;

The ramet population structures of the clonal bamboo Fargesia nitida in different canopy conditions of sulbalpine dark coniferous forest in Wolong Nature Reserve,China;

Compared with the ramet population in the semi-fixed dunes,the ramet population in the fixed dunes exhibited higher ramet density,smaller average ramet spacing and similar ramet height.

Stoloniferous herb Fragaria vesca was sampled in the unshading (open fields) and the shading conditions (forest undergrowth) at the five different altitudes (2426m, 2750m, 3200m, 3484m and 3944m) in the eastern edge of Qing-Zang Platea u in China in order to investigate the characteristics of its ramet population a nd their variation along the altitudinal gradient.
