Research Advance in Forest Community Assembly research
Supported by National Natural Science Foundation of Chaina (NNSFC) and US National Science Foundation, doctorial student in the group led by Prof Zhanqing Hao, in our institute, cooperated with Dr Nate Swenson and others in Michigen State University, investigated the relative contributions of deterministic process and random process to the forest assembly of East United States. Theyuse a new statistic and deduction way—the maximum entropy theory—and illustrated that the relative importance has scale-dependence: when the environment change not much, environmental screening to species traits haveno detectable effect at small scales but has significant effect at middle and large scales. The mass effect of species pool
(spatial diffusion of species caused by difference in species abundance ) has higher contributions at different scales ,indicating regional process has important role in local community assembly. The results were published on line Journal Ecology and Biography(IF:7.2)(doi:10.1111/ge.12167).
