A team of scientists from Northern Arizona University’s Center for Ecosystem Science and Society (Ecoss) and Lawrence Livermore National Laboratory (LLNL) recently announced a major achievement in ecosystem science. Their research, published as “Estimating taxon-specific population dynamics in diverse microbial communities” in the journal Ecosphere, illustrates a powerful new technique Read more…
Measuring the growth rates of individual bacteria taxa within a mixed sample gives a powerful view of the moving parts of a living ecosystem, especially when that sample is soil, where so many ecological processes occur. Ecoss research pioneered “qSIP” — a new method for gathering many simultaneous bacterial growth Read more…
Native soil carbon (C) can be lost in response to fresh C inputs, via the “priming effect,” a phenomenon observed for decades yet still not understood. Using dual-stable isotope probing, Ecoss research showed that priming involves changes in the diversity and composition of two functional bacterial groups: a single-substrate pulse Read more…
