    Tree and shrub diversity in native rainforest fragments in southern Chile

    Pincheira-Ulbrich1 J, JR Rau2, E Hauenstein3

    Phyton-International Journal of Experimental Botany, Vol.77, pp. 321-326, 2008, DOI:10.32604/phyton.2008.77.321

    Abstract We sampled the diversity of trees and shrubs, and built the rarefaction and accumulation species curve in 10 native forest fragments in southern Chile. Results indicated that: (1) there were 23 species in all sampled fragments, (2) species richness increased significantly with fragment size, (3) all fragments require a minimal sampling from 40 to 170 individuals to reach the maximum theoretical species richness, and (4) sampling richness was greater than that theoretically expected (20 species).

    Utility of taxonomic unit and life form in the analysis of plant diversity patterns in a temperate meadow steppe, China

    Han DY1,2, YF Yang2

    Phyton-International Journal of Experimental Botany, Vol.87, pp. 113-122, 2018, DOI:10.32604/phyton.2018.87.113

    Abstract Rapid and precise assessment of biodiversity is a central issue in conservation biology and biodiversity science. Higher taxonomic units and life form-based morphospecies were utilised to assess plant diversity patterns at the habitat scale in temperate meadow steppe, Songnen Plain, China. Patch area, taxonomic composition (families and genera) and life form (based on Raunkiaer’s life forms, and stem and root growth forms) were recorded in five communities. Taxonomic unit-based hierarchical diversity indices (HDI) and life form-based hierarchical diversity indices (HLDI) were calculated. Twenty-six families, 67 genera, and 87 species were recorded in the five communities. HDI and HLDI were significantly… More >
