Higher density: 1.5 m 2 m; low density: 1.five m four m.Based on Tables three and S2, the niche overlap of dominant shrubs within the patterns of diverse compositions and densities can be obtained (Table four), as well as the diversity of shrubs is higher in the patterns with reduced niche overlap of dominant shrubs. By way of example, theForests 2021, 12,9 ofoverlap of dominant shrubs in high-density pure forests is decrease than that of low-density pure forests, along with the overlaps of dominant shrubs in the Cf pattern would be the highest, although the overlap of dominant shrubs within the two mixed tree species patterns is reduced than that of pure forests plus the three tree species mixed with the similar density, which is opposite to the distribution of shrub diversity in every model.Table 4.

Discussion For plantations with poor tree diversity, understory vegetation is definitely an critical a part of the diversity of your whole plantation, giving a habitat and food for a lot of organisms, promoting nutrient cycling, stopping erosion, and affecting seed germination andForests 2021, 12,10 ofseedlings within the forest ecosystem with regard to survival and growth [22]. Within this study, we Olesoxime References carried out distinct patterns of cypress forest transformation, and studied and revealed the diversity of understory shrubs in stands with unique tree compositions and density as well as the connection involving their shrub niches. The outcomes showed that the tree composition and density had a important impact around the diversity of shrubs, and that the niche is closely connected for the diversity of shrubs. In every single transformation pattern, the overlap in the niche from the shrub diversity plus the dom.
