- Abstract
Field surveys and empirical integrated methods are commonly used in the ecological research to understand the altitudinal pattern of plant diversity of mountains. However, few studies have compared the differences between the two methods on the same scale. Here, we addressed and compared the altitudinal patterns of species richness (SR), phylogenetic diversity (PD), the standardized effect size of phylogenetic diversity (PDses) and mean phylogenetic distance (MPDses) of about 580 angiosperms growing on Mount Kenya from two independent datasets: one is based on our several times field surveys in this mountain and another one is based on empirical data integrated from literatures. We found that the altitudinal diversity patterns of field surveys dataset were consistent with the empirical integrated dataset. Both SR and PD showed hump-shaped patterns along the altitude, and both PDses and MPDses showed monotonically decreasing patterns along the altitude. The ratio of diversity between field surveys dataset and empirical integrated dataset were gradually increase along the altitude. Our research provides new insight for understanding the altitudinal diversity patterns of plants of a tropical mountain.
