“…Many studies evaluating the similarities and differences between interspecific and intraspecific diversity and their effect on ecosystem functioning (e.g., Cook‐Patton et al, 2011; Crawford & Rudgers, 2012; Jiang et al, 2021) use a factorial design in which an interspecific diversity gradient is created by varying the numbers of interspecific groups used and the number of intraspecific groups within one or multiple focal interspecific groups is varied by controlling the number of genotypes or seed families (Figure 3a). Consider, for example, an experimental design in which one varies the number of interspecific groups (here species) from one or two to four species and the seed families within species from one or two to four (e.g., Zeng et al, 2017).…”

Rapid environmental changes result in massive biodiversity loss, with detrimental consequences for the functioning of ecosystems. Recent studies suggest that intraspecific diversity can contribute to ecosystem functioning to an extent comparable to contributions of interspecific diversity. Knowledge on the relative importance of these two sources of biodiversity is essential for predicting ecosystem consequences of biodiversity loss and will aid in the prioritization of conservation targets and implementation of management measures. However, our quantitative insights into how interspecific and intraspecific biodiversity loss affects ecosystem functioning and how the effects of these two sources of biodiversity loss on ecosystem functioning can be compared are still very limited. To facilitate such quantitative insights, we extend the interspecific Price partitioning method originally introduced by J. Fox in 2006, previously used to quantify species loss and gain effects on ecosystem functioning, to also account for the effects of intraspecific diversity loss and gain on ecosystem function. Using this extended version can yield the quantitative information required for answering research questions addressing correlations between interspecific and intraspecific diversity effects on ecosystem functioning, identifying interspecific and intraspecific groups with large effects, and assessing whether intraspecific diversity can compensate for losses in interspecific diversity. Applying this method to carefully designed experiments will provide additional insights into how biodiversity loss at different ecological levels contributes to and changes ecosystem functioning.

“…Fundamentally, dominant plant species directly affect ecosystem function because their high biomass determines the rate of ecosystem-level processes, as described by the mass-ratio hypothesis (Grime, 1998). Additionally, dominant plant species may affect soil nutrient cycling by changing plant species diversity (Jiang et al, 2021) or the quality and quantity of senesced material (Hern andez et al, 2022;Koukoura et al, 2003). Finally, the removal or loss of a dominant plant species increases light availability and subsequently changes plant community structure (Emery & Gross, 2007;Hern andez et al, 2022).…”

Dominant plant species are locally abundant and have large impacts on ecological communities via a variety of mechanisms. However, few studies have evaluated the influence of a dominant plant species both within and among trophic levels and on key ecosystem functions such as productivity. In this study, we evaluated the effect of the dominant plant species Solidago canadensis on plant and arthropod communities in an old‐field ecosystem in southeastern Michigan. We found that S. canadensis negatively correlated with the richness and combined biomass of all other plant species in the community, likely by reducing light availability. In turn, less biomass of all other plant species led to lower arthropod abundance. Specifically, detritivore and predator arthropod abundance was lower with less biomass of all plant species excluding S. canadensis, but herbivore and omnivore abundance was unaffected. Our results highlight the significant role of dominant plants in determining plant diversity and ecosystem function, and further suggest that the effect of a dominant plant species on a community is observed at higher trophic levels.

“…Soil microbial stability is affected not only by the degree of disturbance but also depends on the species composition. Previous studies have primarily focused on the impact of variations in abundant subgroups on soil microbial community stability and functions following disturbances (Hernández et al, 2022; Jiang et al, 2021; Jiao et al, 2019; Liu et al, 2022; Tao et al, 2023). Unfortunately, the rare sub‐community is often excluded from the dataset for being below the detection line, systematically neglecting a significant portion of the biosphere and thus underestimating the roles of rare species in maintaining microbial community stability and functions within agroecosystems (Jousset et al, 2017).…”

Stable bacterial communities are essential for maintaining soil functions. However, the role of abundant and rare bacterial taxa in maintaining bacterial community stability remains controversial. To explore the relationship between abundant and rare taxa and bacterial community stability, we used high‐throughput sequencing technology and molecular ecological networks to characterize the distribution of abundant and rare bacterial taxa under different nitrogen (N) fertilization rates (0, 150, 200, and 250 kg N hm−2). Our findings revealed that rare taxa had much higher Simpson's diversity index values than abundant taxa. Moreover, rare taxa Simpson's diversity decreased with increasing N application, while bacterial community differences (Bray–Curtis distance dissimilarity) increased (i.e., bacterial community stability decreased with increasing N application). The network topology showed that rare sub‐communities had higher modularity and a greater proportion of positive links than abundant taxa. The rare bacterial Simpson's diversity was significantly and negatively correlated with bacterial community differences, no correlation occurred between abundant bacterial Simpson's diversity and bacterial community differences. This study underscores the importance of rare species in maintaining bacterial community stability. Consequently, when optimizing agricultural management practices to ensure the stability of bacterial communities and soil functions, it is crucial not only to concentrate consider the roles of abundant species involved in nutrient cycling but also to give greater consideration to the role of rare taxa.
