There are three kinds of causes that cause functional difficulty in predicting the dynamics of community tree species.

Functionality refers to a series of properties that an organism has closely related to its planting, survival, growth and death.
natural communities, functional differences between organisms have been considered an important prerequisite for biodiversity coexistence.
functional-based community ecology studies generally believe that the functionality of species determines the suitability of species in the community, thus affecting the dynamic changes of community species, such as species survival rate, growth rate and mortality rate.
However, many studies around the world have shown that the most commonly used plant morphological traits are not closely related to the dynamics of community species, especially in tree species with long life history cycles. Based on this
, Yang Jie, an associate researcher in the Forest Ecological Structure, Function and Dynamic Research Group of xishuangbanna Tropical Botanical Garden of the Chinese Academy of Sciences, in cooperation with Nathan Swenson, a researcher at the University of Maryland, combined with the previous research on the dynamic changes of functional and community tree species and a comprehensive analysis of the relationship between functional and tree growth of tropical rainforest sedud in Xishuangbanna Tropical Rain Garden, put forward a new insight.
the author points out three reasons that lead to functional difficulty predicting the dynamics of community tree species in the current study, and expounds the limitations of the current research from three aspects: ignoring the correlation background of functional traits and the dynamic changes of community tree species, ignoring individual characteristic changes, and lacking hard patterns that better reflect the acquisition and distribution of tree species resources.
finally pointed out the development direction of future research from the three aspects of comprehensiveness, individual level characteristics and combined transcription group and metabolomics.
the study, based on why e-did not predict tree demographic rates, was published in the international journal Ecology and Evolutionary Biology, Trends in Ecology and Evolution.
the research was supported by the Chinese Academy of Sciences's Strategic Pilot Special Cultivation Special (XDPB0203), the "135th Five-Year Plan" special breakthrough of the Banna Botanical Garden (2017 XTBG-T01), the National Natural Science Foundation (31670442), the Chinese Academy of Sciences Youth Innovation Promotion Association (2016352), the Chinese Academy of Sciences Southeast Asia Biodiversity Research Center Youth Cultivation Project (Y4ZK111B01) and the National Key Development Planning Project (20144050).
