Data were collected from adult and sapling trees in six forest fragments. Adult and sapling density was compared among fragment sizes by the Mann鈥揥hitney test, while diameter distributions were compared by a summary statistic calculated using the scores of a PCA produced with the results of ...
Since different gender determining systems probably evolve separately SCIENTIFIC REPORTS | 5 : 9076 | DOI: 10.1038/srep09076 1 www.nature.com/scientificreports Figure 1 | Flowers of the female and male trees in Salicaceae species. On willow and poplar, the male or female flowers are separately ...
A progressive decrease in tree height on roadsides was observed after the road construction, suggesting tall trees could not withstand the dry and windy roadside environment. The edge effect on the canopy tended to be larger at higher elevation sites. The spatio-temporal pattern of species ...
The existing studies mainly focused on the distribution of tree size, the degree of size heterogeneity, the spatial correlation of trees in different forest layers, and various methods, including distance-related spatial structure function and distance-independent spatial structure–function. For example,...
All trees were planted in a homogeneous matrix, which helped to reduce P. fremontii neighborhood effects. One sample was comprised of few P. fremontii genotypes with many clones. A second sample was comprised of many P. fremontii genotypes with few clones. A second data set was used to ...

Two trees were instrumented with heat pulse sapflux sensors in the Southern Sierra Critical Zone Observatory (SSCZO) within the Kings River Experimental Watershed (KREW) to better understand transpiration as it relates to water availability from deeper sources. At the first instrumented site, CZT-1...
The primary growth of trees consists of germination and flowering in the spring and the growth of branches, leaves, and roots during the growing season [3]. Secondary growth includes cambium differentiation and xylem formation. These are developmental processes driving the radial expansion of woody ...
