Water response of ecosystem respiration regulates future projection of net ecosystem productivity in a semiarid grassland

Recent evidences show that terrestrial biogeochemical models have large uncertainty in estimating climate-change effect on grassland net ecosystem productivity (NEP), which is defined as the difference between gross ecosystem photosynthesis (GEP) and respiration (ER). It remains unclear that whether GEP or ER limits the model capability to simulate NEP responses […]

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 […]

NAU illustrator uses art to translate science

A brand new staff member at Northern Arizona University’s Center for Ecosystem Science and Society, Leshyk’s charge is to use the power of art to help interpret and communicate science produced by the center’s researchers as well as others at the university. It’s a unique opportunity to highlight fascinating science that […]

The economic value of grassland species for carbon storage

Ecoss research demonstrated that grasslands with more diverse plant species pull down and store more carbon per acre: in this illustration, the same plot of soil from a diverse vs.  depauperate grassland shows more belowground investment in deeper roots and denser storage of carbon in a diverse array of plants. […]

The economic value of grassland species for carbon storage

In a groundbreaking study, Ecoss research produced a monetary value for biodiversity by demonstrating that having more diverse plant species enables a grassland to draw down and store more carbon.  This finding allows calculations of how much carbon storage is lost or gained per species added or lost from a […]

The economic value of grassland species for carbon storage

Carbon storage by ecosystems is valuable for climate protection. Biodiversity conservation may help increase carbon storage, but the value of this influence has been difficult to assess. We use plant, soil, and ecosystem carbon storage data from two grassland biodiversity experiments to show that greater species richness increases economic value: […]

Slowed Biogeochemical Cycling in Sub-arctic Birch Forest Linked to Reduced Mycorrhizal Growth and Community Change after a Defoliation Event

Sub-arctic birch forests (Betula pubescens Ehrh. ssp. czerepanovii) periodically suffer large-scale defoliation events caused by the caterpillars of the geometrid moths Epirrita autumnata and Operophtera brumata. Despite their obvious influence on ecosystem primary productivity, little is known about how the associated reduction in belowground C allocation affects soil processes. We […]
