Estimating taxon-specific population dynamics in diverse microbial communities

Understanding how population-level dynamics contribute to ecosystem-level processes is a primary focus of ecological research and has led to important breakthroughs in the ecology of macroscopic organisms. However, the inability to measure population-specific rates, such as growth, for microbial taxa within natural assemblages has limited ecologists’ understanding of how microbial […]

Ecoss scientists develop technique for measuring bacterial growth rates

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 […]

Science on Tap by Bruce Hungate

Bruce Hungate, Ecoss Director, Regents’ Professor, and McAllister Chair in Community, Culture, and Environment is presenting in Science on Tap on ‘Climate Change and Culture on the Colorado Plateau‘.  How will climate change affect our region? How can we respond? Explore the science of climate change, its relationship to society […]

Multi-decadal time series of remotely sensed vegetation improves prediction of soil carbon in a subtropical grassland

Soil carbon sequestration in agroecosystems could play a key role in climate change mitigation but will require accurate predictions of soil organic carbon (SOC) stocks over spatial scales relevant to land management. Spatial variation in underlying drivers of SOC, such as plant productivity and soil mineralogy, complicates these predictions. Recent […]

Losing legacies, ecological release, and transient responses: Key challenges for the future of northern ecosystem science

Northern ecosystem processes play out across scales that are rare elsewhere on contemporary earth: large ranging predator–prey systems are still operational, invasive species are rare, and large-scale natural disturbances occur extensively. Disturbances in the far north affect huge areas of land and are difficult to control or manage. Historically, disturbance […]

Ecosystem vs. community recovery 25 years after grass invasions and fire in a subtropical woodland

Despite a large body of research documenting invasive plant impacts, few studies have followed individual invaded sites over decades to observe how they change, and none have contrasted how compositional impacts from invasion compare to ecosystem-process impacts over a multi-decadal time-scale. Using direct measurements of plant density and composition and […]
