Abstract Background Changes in foliar nitrogen (N) and phosphorus (P) stoichiometry play important roles predicting the effects of global change on ecosystem structure function. However, there is substantial debate P addition N stoichiometry, particularly under different levels addition. Thus, we conducted a meta-analysis to investigate how alters across rates durations plant growth types based...

Potassium channel openers (KCOs; e.g., P1075, pinacidil) exert their effects on excitable cells by opening ATP-sensitive potassium channels. These channels are heteromultimers composed with a 4:4 stoichiometry of an inwardly rectifying K(+) channel subunit plus a regulatory subunit comprising the receptor sites for hypoglycemic sulfonylureas and KCOs (a sulfonylurea receptor). To elucidate stoi...

Flux balance analysis (FBA) determines theoretical capabilities of metabolic networks using only stoichiometry and fundamental physiochemical capacity constraints. Metabolic networks reconstructed from annotated genome and literature. Capacity constraints include maximum uptake rates of oxygen and substrates such as glucose, acetate, and lactose. FBA determines optimal flux distribution for giv...

We lack both a theoretical framework and solid empirical data to understand domestication impacts on plant chemistry. We hypothesised that domestication increased leaf N and P to support high plant production rates, but biogeographic and climate patterns further influenced the magnitude and direction of changes in specific aspects of chemistry and stoichiometry. To test these hypotheses, we use...

Understanding the contents and stoichiometry of carbon (C), nitrogen (N), phosphorus (P) is vital to evaluate function processes a forest ecosystem. Overall, 18 sites in Shennongjia Forest from an altitude 800 3000 m were selected collect litterfall, humus, soil (0–20 20–40 cm) samples May, August, December. The spatio-temporal distribution C, N, P their quantified, underlying driving factors a...

The ability of oligomeric membrane proteins to assemble in different functional ratios of subunits is a common feature across many systems. Recombinant expression of hetero-oligomeric proteins with defined stoichiometries facilitates detailed structural and functional analyses, but remains a major challenge. Here we present two methods for overcoming this challenge: one for rapid virus titratio...

There has been important progress in understanding ecological dynamics through the development of the theory of ecological stoichiometry. For example, modeling under this framework allows food quality to affect consumer dynamics. While the effects of nutrient deficiency on consumer growth are well understood, recent discoveries in ecological stoichiometry suggest that consumer dynamics are not ...

Under the current paradigm, organic matter decomposition and nutrient cycling rates are a function of the imbalance between substrate and microbial biomass stoichiometry. Challenging this view, we demonstrate that in an individual-based model, microbial community dynamics alter relative C and N limitation during litter decomposition, leading to a system behaviour not predictable from stoichiome...

Abstract Eutrophication is the most widespread water quality issue globally. To date, efforts to control eutrophication have focused on reductions of external nutrient inputs, yet importance stoichiometry and subsequent shift in plankton composition aquatic ecosystem has been largely neglected. address eutrophication, improved sanitation one United Nations Sustainable Development Goals, spurrin...

Aim While physical constraints influence terrestrial primary productivity, the extent to which geographical variation in productivity is influenced by physiological adaptations and changes in vegetation structure is unclear. Further, quantifying the effect of variability in species traits on ecosystems remains a critical research challenge. Here, we take a macroecological approach and ask if va...
