  • interaction between Plant Competition and rhizospheric bacterial community influence secondary succession of abandoned farmland on the loess plateau of china
    2018
    Co-Authors: Caili Sun, Guobin Liu, Sha Xue
    Abstract:

    Interactions between Plant and soil have important implication for Plant Competition, development and succession. In order to explore the internal mechanism behind natural succession of abandoned farmland, we test the effect of Plant-soil interaction on Plant growth and competitive ability through performing a pot experiment, which included three grasses in different successional stages on the Loess Plateau of China (Setaria viridis, Stipa bungeana and Bothriochloa ischaemum) in monoculture and all possible two- and three-way combinations, along with a Plant-free control pot. The Plants were harvested after about four months, and the rhizospheric soil was collected. The bacterial communities of the soils were analyzed by high-throughput sequencing of the 16S rRNA gene. Plant Competition affected richness of bacterial communities. Proteobacteria and Bacteroidetes were generally higher and Actinobacteria and Acidobacteria were lower in relative abundance in the mixed treatments associated with B. ischaemum. Photosynthetic bacterium, Genus Rhodobacter family Rhodospirillaceae, affected the growth condition and increased the competitive ability of B. ischaemum. Differences in the amounts of soil organic carbon, water-soluble organic carbon and nitrate nitrogen and available phosphorus drove the differences in bacterial communities. Our study has an important significance for understanding the trend of natural succession on the abandoned farmland on the Loess Plateau of China.

  • incorporating the soil environment and microbial community into Plant Competition theory
    2015
    Co-Authors: Takeshi Miki
    Abstract:

    Plants affect microbial communities and abiotic properties of nearby soils, which in turn influence Plant growth and interspecific interaction, forming a Plant-soil feedback (PSF). PSF is a key determinant influencing Plant population dynamics, community structure, and ecosystem functions. Despite accumulating evidence for the importance of PSF and development of specific PSF models, different models are not yet fully integrated. Here, we review the theoretical progress in understanding PSF. When first proposed, PSF was integrated with various mathematical frameworks to discuss its influence on Plant Competition. Recent theoretical models have advanced PSF research at different levels of ecological organizations by considering multiple species, applying spatially explicit simulations to examine how local-scale predictions apply to larger scales, and assessing the effect of PSF on Plant temporal dynamics over the course of succession. We then review two foundational models for microbial- and litter-mediated PSF. We present a theoretical framework to illustrate that although the two models are typically presented separately, their behavior can be understood together by invasibility analysis. We conclude with suggestions for future directions in PSF theoretical studies, which include specifically addressing microbial diversity to integrate litter- and microbial-mediated PSF, and apply PSF to general coexistence theory through a trait-based approach.

  • interspecific Plant Competition increases soil labile organic carbon and nitrogen contents

    Abstract:

    Abstract Plant Competition can impose species-specific effects on the dynamics of soil carbon (C) and nitrogen (N) through rhizosphere processes and litter input. Therefore, it is crucial to quantify these effects in various terrestrial ecosystems for a better understanding of the mechanisms. Here, we collected subsoils containing low N from a subtropical forest and Planted eight dominant tree species (two deciduous and six evergreens) in these soils in a greenhouse to explore the effects of interspecific Plant Competition on Plant growth, soil C and N contents, and soil C and N mineralization rates after the Plants had grown for 12 months. Soil labile organic C and N contents were represented by soil extractable organic C (EOC) and extractable organic N (EON) contents. We assessed the magnitude of the interspecific Plant Competition via the relative interaction intensity (RII) index, which was calculated from the biomass of seedlings in the mixed treatments compared with the single treatments. Our results showed that interspecific Plant Competition had species-specific effects on Plant biomass and soil total C and N contents as well as soil C mineralization rates, whereas it tended to decrease soil N mineralization rates. However, interspecific Plant Competition significantly decreased Plant C and N contents, and significantly increased soil EOC and EON contents with increasing RII. After classifying the communities into two functional types (i.e., deciduous–evergreen versus evergreen–evergreen), similar relationships were observed. These findings address the importance of quantifying interspecific Plant Competition on soil labile organic C and N contents, which is helpful for understanding soil C and N cycling in forest ecosystems.
