New ECOSS study suggests phosphorus matters everywhere

New research from Northern Arizona University researchers challenges long-held assumptions that phosphorus limits aboveground plant growth mainly in tropical regions but not others. The paper, published this week in Nature Communications, suggests that this important nutrient actually helps govern plant production in temperate regions, too, and on every continent except […]

The inhibitory effects of nitrogen deposition on asymbiotic nitrogen fixation are divergent between a tropical and a temperate forest

Asymbiotic nitrogen (N) fixation (ANF) is an important source of N in pristine forests and is predicted to decrease with N deposition. Previous studies revealing N fixation in response to N deposition have mostly applied understory N addition approaches, neglecting the key processes (for example, N retention and uptake) occurring […]

Snowmelt and early to mid-growing season water availability augment tree growth during rapid warming in southern Asian boreal forests

Boreal forests are facing profound changes in their growth environment, including warming-induced water deficits, extended growing seasons, accelerated snowmelt, and permafrost thaw. The influence of warming on trees varies regionally, but in most boreal forests studied to date, tree growth has been found to be negatively affected by increasing temperatures. […]

Soil water availability drives changes in community traits along a hydrothermal gradient in Loess Plateau Grasslands

Plant functional traits can be used to predict ecosystem responses to climate gradients, yet precipitation explains very little variation for most traits. Soil water availability directly influences plant water uptake and thus may assist with the improvement of plant trait–water relationships. However, this promise remains poorly realized due to rare […]

Straw incorporation influences soil organic carbon sequestration, greenhouse gas emission, and crop yields in a Chinese rice (Oryza sativa L.) –wheat (Triticum aestivum L.) cropping system

Crop straw management plays important roles in sustainable agriculture and environmental protection. Straw incorporation has multiple influences on soil organic carbon (SOC) sequestration, greenhouse gas (GHG) emissions, and crop yields, but these influences have rarely been studied simultaneously in a single cropping system. This study was conducted to examine the […]
