We used trait-based approaches to reveal the functional responses of springtails communities to organic matter inputs in a rubber plantation in Côte d’Ivoire. Pitfall traps were used to sample springtails in each practice. The results showed that the total abundance of springtails increased significantly with the amount of organic matter (R0L0 < R2L1). Larger springtails (body length, furca and antennae) were observed in plots with high organic matter. Practices with logging residues and legume recorded the highest functional richness. The principal coordinate analysis showed different functional composition patterns between practices with logging residues (R1L1 and R2L1) and those without inputs (R0L0 and R0L1). This difference in functional composition (PERMANOVA analysis) was related to the effect of practices. These results highlight the pertinence of the functional trait approach in the characterization of springtail communities, a bioindicator of soil health, for organic matter management practice.
我们采用基于性状的方法,揭示了科特迪瓦橡胶种植园中跳虫群落对有机质输入的功能响应。在每种实践中,使用陷阱诱捕法对跳虫进行采样。结果表明,跳虫的总丰度随有机质含量的增加而显著增加(R0L0 < R2L1)。在有机质含量高的地块中观察到体型较大的跳虫(体长、尾叉和触角)。有伐木剩余物和豆科植物的实践记录了最高的功能丰富度。主坐标分析显示,有伐木剩余物的实践(R1L1和R2L1)与无输入的实践(R0L0和R0L1)之间存在不同的功能组成模式。功能组成的这种差异(PERMANOVA分析)与实践的影响有关。这些结果突出了功能性状方法在表征跳虫群落(土壤健康的生物指标)以进行有机质管理实践方面的相关性。
