“…Shifts in biomass C:N have also been observed in response to altered substrate stoichiometry (Fanin et al, 2013) and changes in community composition under drought (Cregger et al, 2012). Increasing biomass C:N may enhance soil C storage if biomass turnover is slow (Treseder et al, 2010) or if microbes synthesize extremely recalcitrant compounds that are difficult to decompose (Rillig et al, 2001). However, if microbial residues are decomposed more rapidly than plant litter inputs (e.g., Throckmorton et al, 2012) or larger microbial biomass C pools correspond to higher respiration rates over the long term, increases in the size or C content of the microbial biomass may actually enhance soil C loss.…”

“…The actual hyphal growth mechanisms or rates over a biotite surface (or any other mineral surface for that matter) are unknown. The only values available for hyphal turnover rates in soils vary from 7 days (Staddon et al, 2003) to 145 days (Treseder et al, 2010). Thus, an independent check of our hyphal growth rate estimate is difficult.…”

“…Moreover, the rate of change in microbial communities can vary depending on microbial growth strategies (de Vries and Shade ), severity, and type of disturbance (Allison and Martiny ), and habitat (Lauber et al , Shade et al ). In some cases, for example, composition and abundance of bacteria and fungi can shift in days to months after disturbance (Treseder et al ), whereas in other communities similar shifts can take years (Treseder et al ).…”

The spatial and temporal linkages between turnover of soil microbial communities and their associated functions remain largely unexplored in terrestrial ecosystems. Yet defining these relationships and how they vary across ecosystems and microbial lineages is key to incorporating microbial communities into ecological forecasts and ecosystem models. To define linkages between turnover of soil bacterial and fungal communities and their function we sampled fungal and bacterial composition, abundance, and enzyme activities across a 3‐ha area of wet tropical primary forest over 2 yr. We show that fungal and bacterial communities both exhibited temporal turnover, but turnover of both groups was much lower than in temperate ecosystems. Turnover over time was driven by gain and loss of microbial taxa and not changes in abundance of individual species present in multiple samples. Only fungi varied over space with idiosyncratic variation that did not increase linearly with distance among sampling locations. Only phosphorus‐acquiring enzyme activities were linked to shifts in septate, decomposer fungal abundance; no enzymes were affected by composition or diversity of fungi or bacteria. Although temporal and spatial variation in composition was appreciable, because turnover of microbial communities did not alter the functional repertoire of decomposing enzymes, functional redundancy among taxa may be high in this ecosystem. Slow temporal turnover of tropical soil microbial communities and large functional redundancy suggests that shifts in abundance of particular functional groups may capture ecosystem function more accurately than composition in these heterogeneous ecosystems.
