The decomposition of soil organic matter (SOM) can be described by a set of kinetic principles, environmental constraints, and substrate supply. Here, we hypothesized that SOM decomposition rates (R) and its temperature sensitivity (Q 10) would increase steadily with the N:C ratios of added substrates by alleviating N limitation on microbial growth. We tested this hypothesis by investigating SO...

Global warming and nitrogen (N) deposition have an important influence on terrestrial ecosystems; however, the influence of warming and N deposition on plant photosynthetic products and nutrient cycling in plants is not well understood. We examined the effects of 3 years of warming and N addition on the plant photosynthetic products, foliar chemistry and stoichiometric ratios of two dominant sp...

Abstract Extreme precipitation is occurring with greater frequency and intensity as a result of climate change. Such events boost the transport allochthonous organic matter (allo-OM) to freshwater ecosystems, yet little known about impacts on dissolved (DOM) quality seston elemental stoichiometry, especially for lakes in warm climates. A mesocosm experiment located Turkish lake was designed sim...

Boreal forests have been evidenced to be highly sensitive enhanced nitrogen (N) deposition due prevailing N limitations, and external inputs from atmospheric are expected alter plant nutrient stoichiometry. Previous studies mostly focused on the dominant tree species while neglecting understory plants that often play important role in cycles forest ecosystems. By conducting a six-year N-additio...

Agriculture alters the biogeochemical cycling of nutrients such as nitrogen (N), phosphorus (P), and silicon (Si) which contributes to stoichiometric imbalance among these in aquatic systems. Limitation Si relative N P can facilitate growth non-siliceous, potentially harmful, algal taxa has severe environmental economic impacts. Planting winter cover crops retain on landscape, yet their effect ...
