species-richness

And the higher the species richness, landform presents heterogeneity, and the fewer hummocks , the bigger the surface roughness.

Species diversity consist of species richness, the total number of species, species evenness, and the distribution of species.

Species richness of family, genera, species, tree, and shrub decreased at the early stage and then increased with community succession.

As a consequence, the species richness of different communities were gradually lowered with the aggravating of grazing intensity.

But it looks as though their species richness is caused by the same underlying mechanism.

The herbage had the highest species richness in park green belts, shrub species secondly, the arbor was a little lower than shrub.

A stronger complementary effect was observed inside the assemblage, presenting a hump-shaped variation with increasing species richness.

No significant correlation was observed between species richness and latitudinal or longitudinal variations.

The species richness and species diversity index of the tree layer and shrub layer were obviously bigger than those of the herb layer.

The species richness and individual changes correspond well with the diversity indexes change .

As for distribution of plant species, richness of native plant decreases along rural, rural-urban fringe and urban gradient.

The colony specific growth rate in the exponential growth phase increased with increasing species richness.

Species richness and diversity index show an upward trend, but species evenness index shows reveres variation.

From shrub canopy to open space, the herb plant coverage and height decreased, while the species richness increased.

This thesis mainly discusses the species diversity, evenness and species richness of three main factor.

The altitudinal patterns of species richness at family, genus and species levels were consistent with the mid-domain effect hypothesis.

The variety of species richness in seed band within gap is large, which is a important factor determining the distribute of seedlings.

With the increase of N addition, both the species richness and the diversity decreased.

Insect species richness was high, and the community structure complex and stable.

As mentioned above, the fish nematodes from Yellow Sea has a low species richness.

Area Serai, intertwined vines and plant species richness.

In this paper, we examined the breeding bird species richness along an elevational gradient in northern Taiwan.

while dry land had the highest abundance and dominance, and the lowest species richness and diversity.

Species richness of shrubland in the Project Area is considered very low.

Very few showed significant declines in species richness with distance froms ubplot boundaries.

Species richness of conifer forest was 15 and more than that of broad-leaved mixed forest.
