The application of ecological stoichiometry to plant–microbial–soil organic matter transformations

Ecological Monographs, Journal Year: 2015, Volume and Issue: 85(2), P. 133 - 155

Published: April 24, 2015

Elemental stoichiometry constitutes an inherent link between biogeochemistry and the structure processes within food webs, thus is at core of ecosystem functioning. Stoichiometry allows for spanning different levels biological organization, from cellular metabolism to nutrient cycling, therefore particularly useful establishing links compartments. We review elemental carbon : nitrogen phosphorus (C:N:P) ratios in terrestrial ecosystems (from vegetation, leaf litter, woody debris, dead roots, soil microbes organic matter). While plant, compartments well understood, heterotrophic microbial communities, which dominate web drive have received increasing interest recent years. This highlights effects resource on microorganisms decomposition, specifically function communities suggests several general patterns. First, latitudinal gradients litter are reflected community function. Second, may cause changes interactions dynamics that lead feedbacks availability. Third, global change alters C:N, C:P, N:P primary producers, with repercussions decomposer critical services such as fertility. argue ecological provides a framework analyze predict various scales.

Carbon use efficiency of microbial communities: stoichiometry, methodology and modelling

Ecology Letters, Journal Year: 2013, Volume and Issue: 16(7), P. 930 - 939

Published: April 30, 2013

Abstract Carbon use efficiency ( CUE ) is a fundamental parameter for ecological models based on the physiology of microorganisms. determines energy and material flows to higher trophic levels, conversion plant‐produced carbon into microbial products rates ecosystem storage. Thermodynamic calculations support maximum value ~ 0.60 max ). Kinetic stoichiometric constraints growth suggest that in multi‐resource limited natural systems should approach 0.3 /2). However, mean values reported aquatic terrestrial ecosystems differ by twofold (~ 0.26 vs. 0.55) because methods used estimate generally soil estimates are less likely capture full maintenance costs community metabolism given difficulty measurements water‐limited environments. Moreover, many simulation lack adequate representation spilling pathways metabolism, which can also lead overestimates . We recommend broad‐scale 0.30, unless there evidence lower as result pervasive nutrient limitations. Ecosystem operating at finer scales consider resource composition, biomass well environmental drivers, predict communities.

Nitrogen limitation of decomposition and decay: How can it occur?

Global Change Biology, Journal Year: 2017, Volume and Issue: 24(4), P. 1417 - 1427

Published: Nov. 9, 2017

The availability of nitrogen (N) is a critical control on the cycling and storage soil carbon (C). Yet, there are conflicting conceptual models to explain how N influences decomposition organic matter by microbial communities. Several lines evidence suggest that limits decomposition; earliest stages leaf litter decay associated with net import from environment, both observations show high decomposes more rapidly. In direct contrast these findings, experimental additions inorganic soils broadly suppression activity, which inconsistent limitation decomposition. Resolving this apparent contradiction representing nutrient dynamics in predictive ecosystem under multitude global change factors alter availability. Here, we propose new framework, Carbon, Acidity, Mineral Protection hypothesis, understand effects C explore predictions framework mathematical model. Our model simulations demonstrate addition can have opposing separate pools (particulate mineral-protected carbon) because they differentially affected biomass growth. Moreover, changes frequently linked shifts pH or osmotic stress, independently affect mask stimulation activity. Thus, effect dependent upon interactions among physiology, mineralogy, acidity. We believe our synthesis provides applicable predict change.
