Combining the different aspects of biodiversity is an important method to explore different spatial and tempor scales to reveal the mechanism of community construction.
at present, the study of the formation mechanism of bird community in combination with species, functional ity and systematic development already has little report, and the study based on system development or functionality is mainly concentrated in some groups.
whether there will be changes in the leading ecological process of bird community construction between different seasons is an ecological topic to be discussed for temperate bird communities with obvious seasonal species composition changes.
recently, the Chinese Academy of Sciences Xishuangbanna Tropical Botanical Garden community construction and species coexistence research group assistant researcher and snow lotus in the bird breeding period and winter, respectively, in the breeding period and winter of the west slope of the mountain has been the bird population of the species as the research object, analysis of community species, functional and systematic development diversity, and build a zero model, obtained the bird-shaped bird-like and functional and systematic development structure.
functional and systematic developmental structure analysis shows that whether in the breeding period or winter, the environment filter is the leading ecological process of the construction of high-altitude bird colonies, and competitive exclusion is more important in the construction of low-altitude bird colonies.
the study also found that, at all altitude gradients, competitive rejection was enhanced in the construction of the bird community during the breeding period, while the environmental filtering effect decreased, which may be related to increased resources available to birds during the breeding period but the resulting increased breeding competition.
research on A taxonomic, functional, and phylogenetic perspective on the community assembly of passerine birds long an gradient in southwest China, published in the ecological journal Ecology and Evolution.
the research was supported by the National Natural Science Foundation of China Youth Science Fund, the "135" project of the Chinese Academy of Sciences, and the Project of the Southeast Asian Biodiversity Research Center of the Chinese Academy of Sciences.
