Seasonal patterns in microbial communities inhabiting the hot springs of Tengchong, Yunnan Province, China

Studies focusing on seasonal dynamics of microbial communities in terrestrial and marine environments are common; however, little is known about seasonal dynamics in high-temperature environments. Thus, our objective was to document the seasonal dynamics of both the physicochemical conditions and the microbial communities inhabiting hot springs in Tengchong County, Yunnan […]

Global warming and shifts in cropping systems together reduce China’s rice production

Climate warming is widely expected to affect rice yields, but results are equivocal and variation in rice cropping systems and climatic conditions complicates country-scale yield assessments. Here we show, through meta–analysis of field warming experiments, that yield responses to warming differ strongly between China’s rice cropping systems. Whereas warming increases […]

Associations between riparian plant morphological guilds and fluvial sediment dynamics along the regulated Colorado River in Grand Canyon

Effects of riparian vegetation on fluvial sediment dynamics depend on morphological traits of the constituent species. Determining the effects of different morphological guilds on sedimentation rates, as influenced by multiple aspects of dam operations, can help identify viable strategies for streamflow and vegetation management to achieve riparian resource goals. Plants […]

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 […]
