Species Diversity Distribution Patterns of Chinese Endemic Seed Plants Based on Geographical Regions

Species Diversity Distribution Patterns of Chinese Endemic Seed Plants Based on Geographical Regions

Based on a great number of literatures, we established the database about the Chinese endemic seed plants and analyzed the compositions, growth form, distribution and angiosperm original families of them within three big natural areas and seven natural regions. The results indicate that the above characters of Chinese endemic plants take on relative rule at the different geographical scales. Am...

Diversity distribution patterns of Chinese endemic seed plant species and their implications for conservation planning

Endemism is an important concept in biogeography and biodiversity conservation. China is one of the richest countries in biodiversity, with very high levels of plant endemism. In this study, we analysed the distribution patterns of diversity, the degree of differentiation, and the endemicity of Chinese endemic seed plants using the floristic unit as a basic spatial analysis unit and 11 indices....

Determination of effective environmental factors on plants functional diversity and species diversity in Ravar rangelands

The aim of the study was to investigate affecting environmental factors on functional diversity indices and species diversity for the fluctuation of the management according to the ecological conditions in Raver rangeland. To determine the functional attributes of rangeland plants, 12 height points were selected along elevation gradient those were distance between them100 meters. 5 sampling plo...

Heteroploid reticulate evolution and taxonomic status of an endemic species with bicentric geographical distribution

Reticulate evolution is considered to be among the main mechanisms of plant evolution, often leading to the establishment of new species. However, complex evolutionary scenarios result in a challenging definition of evolutionary and taxonomic units. In the present study, we aimed to examine the evolutionary origin and revise the species status of Campanula baumgartenii, a rare endemic species f...
