Summary: This study examines the nutrient dynamics in Flathead Lake over a period of 38 years. Despite low nutrient levels, the lake maintained high nitrogen to phosphorus ratios. This stoichiometric imbalance led to phosphorus limitation in phytoplankton growth and affected the nutrient cycling in the entire ecosystem.

Summary: Over the past 15 years in China, there has been excessive input of nitrogen and phosphorus, resulting in a significant decrease in the nitrogen to phosphorus ratio. While nitrogen use efficiency has increased, most crops have shown a decreasing trend in phosphorus use efficiency. This highlights the need for further exploration in phosphorus management for sustainable agriculture.

Summary: The conversion of paddy cropping to vegetable and jasmine production resulted in increased soil CO2 emissions and decreased CH4 and N2O emissions. Global warming potential increased, while TP concentration increased in vegetable soils and TN concentration decreased in jasmine soils.

Summary: This study investigated the biogeographical patterns of nutrient content in bryophytes and their relationship with environmental factors in Sichuan province, China. The results showed that the nutrient content of bryophytes was positively correlated with soil nutrient content and negatively correlated with mean annual precipitation and shrub and herb cover. Soil nutrient content and mean annual temperature were found to be the main driving factors for the nutrient content of bryophytes. This study provides valuable insights into the ecological role of bryophytes in nutrient cycling in ecosystems.

Summary: The seasonal drawdown of dissolved inorganic carbon in the subtropical upper ocean contributes significantly to net community production globally. While surface macronutrients are chronically depleted, nanomolar increases in surface nitrate plus nitrite and phosphate from summer to winter in the western subtropical North Pacific are found to be in near-stoichiometric balance with microbial C:N:P ratios. These findings suggest that the nanomolar upward supply of phosphorus and its preferential recycling play a vital role in sustaining net community production in oligotrophic ocean environments.

Summary: This study investigated the effects of elevation gradients on the C, N, and P content of different tissues of Qinghai spruce, and found that Qinghai spruce is more susceptible to N limitation. The N content and N:P ratio of Qinghai spruce were significantly negatively correlated with temperature, and the P content was lower at high elevation. Soil-climate interactions on the elevation gradient predominantly drove the variation in C, N, and P content and stoichiometry of Qinghai spruce trees in each tissue type. These findings are important for future forest management in coniferous tree growing regions and contribute to understanding the elevational patterns of forest ecosystem stoichiometry in arid and semiarid regions.

Summary: This study examined the C:N:P stoichiometry of temperate orchids and found that the trophic mode of plants influences their elemental composition. The results suggest that mycoheterotrophic orchids have higher nutrient requirements compared to other mycoheterotrophic plants, which may result in higher fungal specificity. These findings provide insights into the evolution of nutrient acquisition in mycoheterotrophic plants.

Summary: This study investigated the impact of water supply on plant stoichiometry, specifically the ratio of carbon to nitrogen (C:N) and nitrogen to phosphorus (N:P) ratios, in four dominant grass species in the Inner Mongolia steppe. The results showed that water supply significantly affected C:N and N:P, and the responses varied among grass species.

Summary: The chemical composition and stoichiometry of vertebrate bodies change significantly during development, and this study quantifies the ontogenetic variation in 10 species of fish. The results show that there is relatively similar variation in body composition and ratios among species, and these trends are better reflected in relative size rather than age. Phosphorus and nitrogen concentrations increase rapidly in early development, while carbon and ratios of C:N, C:P, and N:P decrease. As fish grow, changes in body composition and ratios become less significant.

Summary: The study found that although salps produce 4 times more carbon fecal pellets than krill, both species contribute equally to carbon flux at 300 meters depth, accounting for 75% of total carbon. While 72% of krill fecal pellets are exported to 300 meters depth, 80% of salp fecal pellets are retained in the mixed layer due to fragmentation.

Summary: Aquatic plant nutrient concentrations can vary greatly, with Juncus bulbosus able to thrive in nutrient-dilute waters due to its high carbon-to-nutrient ratios and slow growth. Stoichiometric ratios of C, N, P, and C:N:P in Juncus bulbosus vary with the time of year, habitats, and organs, but do not differ significantly between growth forms. The mass development of J. bulbosus requires C, N, and P, regardless of the ecosystem, challenging previous studies that suggested only CO2 and NH4 were essential nutrients.

Summary: This study investigates the long-term trends in carbon (C), nitrogen (N), and phosphorus (P) exports in a river system in Quebec, Canada. The results show that N exports have increased over time, largely driven by changes in precipitation and net anthropogenic N inputs on land. On the other hand, P exports have tended to decrease, despite higher net anthropogenic P inputs. The study also reveals changes in ecosystem stoichiometry over the years, reflecting the differential elemental exports influenced by natural and anthropogenic drivers.

Summary: Our study found that the capability of microbial community to reduce its demand for external nutrients is responsible for the difference between the predictions and observations. The active part of microbial community instantly recycled N from decaying part of microbial community and very likely utilized internal P sources (i.e. polyphosphates). The results suggest that N recycling from dead microbial biomass and the internal microbial P sources warrant further investigation.

Summary: This research explores the common trait of nitrate-uptake restraint in Proteaceae and co-occurring plant species in south-western Australia. It was found that many plant species in this region have evolved to have this trait as a response to the severely phosphorus-impoverished soils.

Summary: Rice-crayfish integrated farming can significantly enhance the accumulation of soil carbon, nitrogen, and phosphorus. Long-term farming has an impact on soil CNP storage and stoichiometry. Regulation of fertilizer input and improving feed utilization efficiency are crucial for ensuring soil nutrient balance and sustainable development.
