Abstract:
Abstract. Inorganic carbon and nutrient biogeochemical responses were studied during the 2005 Pelagic Ecosystem CO2 Enrichment (PeECE III) study. Inverse analysis of the temporal inorganic carbon dioxide system and nutrient variations was used to determine the net community stoichiometric uptake characteristics of a natural pelagic ecosystem production perturbed over a range of pCO2 scenarios (350, 700 and 1050 μatm). Nutrient uptake showed no sensitivity to CO2 treatment. There was enhanced carbon production relative to nutrient consumption in the higher CO2 treatments which was positively co

Abstract:
Carbon, nitrogen, and phosphorus—nutrient and restrictive elements for plant growth and important components of the plant body—are mainly transferred and exchanged between plants and the soil environment. Changes in the carbon, nitrogen, and phosphorus eco-stoichiometry greatly impact the growth and expansion of Spartina alterniflora, and understanding these changes can reveal the nutrient coordination mechanism among ecosystem components. To explore the relationship between leaf and soil eco-stoichiometry and determine the key soil factors that affect leaf eco-stoichiometry, we collected leaf

Abstract:
Clarifying carbon (C), nitrogen (N), and phosphorus (P) ecological stoichiometry helps us to understand the ecological functions of wetland ecosystems. This study investigated the variations in ecological stoichiometry and their driving factors in the Yellow River wetland. Soil and plant samples were collected and analyzed from riparian lower-beach wetland (LBW), riparian higher-beach wetland (HBW), and depressional wetland (DW) at the junction of the middle and lower reaches of the Yellow River, respectively. Compared with HBW, DW exhibited higher soil C/N (9.15 ± 0.13), C/P (11.17 ± 0.52), a

Abstract Aims The theory of ecological stoichiometry mostly builds on studies of natural terrestrial ecosystems, whereas only limited stoichiometry information is available in response to agronomic practices. Methods We designed a greenhouse experiment in order to disentangle the specific role of cover crop identity and soil characteristic in affecting nutrient stoichiometry of a plant-microbe-soil system. Results Nutrient ratios of cover crop biomass were species-specific and the growth rate explained, for most species considered, the stoichiometric differences in response to soil type. In co

Abstract. Marine phytoplankton stoichiometry links nutrient supply to marine carbon export. Deviations of phytoplankton stoichiometry from Redfield proportions (106C : 1P) could therefore have a significant impact on carbon cycling, and understanding which environmental factors drive these deviations may reveal new mechanisms regulating the carbon cycle. To explore the links between environmental conditions, stoichiometry, and carbon cycling, we compared four different models of phytoplankton C : P: a fixed Redfield model, a model with C : P given as a function of surface phosphorus concentrat

Abstract:
Carbon (C), nitrogen (N), and phosphorus (P) are vital nutrients in the soil, exerting a profound influence on the primary productivity of ecosystems. However, our understanding of how the understory influences soil nutrients and their stoichiometry remains limited, especially in cold-temperate forests where the understory plays a crucial role in mediating soil nutrient cycling. To elucidate the effect of understory vegetation on soil nutrients, three typical larch forests, namely Sphagnum–Bryum–Rhododendron tomentosum–Larix gmelinii forest (SLL), Rhododendron dauricum–Larix gmelinii forest (R

Abstract:
Wetland ecosystems can store large amount of carbon (C) and serve as a biogeochemical ‘hotspot’ for nutrient retention. According to Ramsar Convention, wetlands are defined as areas permanent or temporary with fresh, brackish or saltwater, including areas of marine water the depth of which at low tide does not exceed 6 metres. The C and nutrient dynamics in soil depends on an array of biotic and abiotic factors as well as their interactions. Soil microbial demand of C and nutrients is regulated by the elemental stoichiometry of microbial biomass and resource availability in the environment. Gl

Nutrient ratios have long been analyzed in primary producers, but their application to animals is more recent. Here, we summarize the ecological stoichiometry framework and highlight three key contexts in stream fish ecology: body stoichiometry, dietary stoichiometry, and roles in ecosystem nutrient cycling.

Abstract:
Nitrogen forms an essential element for marine organisms and plays a pivotal role in controlling productivity in various parts of the ocean. Nitrogen, being present in various oxidation states ranging from ammonium to nitrate, acts both as an electron acceptor and donor. Nitrification, the oxidation of ammonia to nitrite and nitrate, is probably the dominant type of chemoautotrophic metabolism in the ocean and may be unique in that it takes place in the oxidized water column. Nitrification is a central process in the nitrogen cycle, which is closely associated with phosphorous, carbon and othe
