ABSTRACT In soil, the link between microbial diversity and carbon transformations is challenged by concept of functional redundancy. Here, we hypothesized that redundancy may decrease with increasing source recalcitrance coupling C cycling change accordingly. We manipulated to examine how affects decomposition easily degradable (i.e., allochthonous plant residues) versus recalcitrant autochthonous organic matter) sources. found a in (i) affected both sources, thereby reducing global CO 2...
Summary Despite the central role of microbes in soil processes, empirical evidence concerning effect their diversity on stability remains controversial. Here, we addressed ecological insurance hypothesis by examining microbial communities along a gradient response to mercury pollution and heat stress. Diversity was manipulated dilution extinction approach. Structural functional stabilities were assessed from patterns genetic structure respiration after Dilution led establishment consistent...
Summary The characteristics of dissolved organic matter ( DOM ) in soils are often determined through laboratory experiments. Many different protocols can be used to extract from soil. In this study, we five air‐dried compare three extraction methods for water‐extractable WEOM as follows: (i) pressurised hot‐water‐extractable carbon PH‐WEOC ), a percolation at high pressure and temperature; (ii) WEOC 1‐hour end‐over shaking; (iii) leaching‐extractable LEOC leaching soil columns ambient...
Soil respiration (RS) is the primary source of atmospheric carbon dioxide from terrestrial ecosystems. RS has been shown to respond exponentially temperature, a relationship summarized by Q10 parameter, which quantifies increase in with 10°C rise temperature. depends on both temperature and soil water content, but latter’s effect remains unclear, especially temperate forests. Unlike whose influence widely accepted, content’s more site-due multiple factors such as...
A multiproxy sedimentary record from Lake Igaliku in southern Greenland documents 1450 years of human impacts on the landscape. Diatoms, scaled chrysophytes, and C N geochemistry show perturbations consistent with recent agricultural activities (post-ad 1980), superimposed upon long-term environmental variability. While response to Norse agriculture (~ad 986–1450) is weak, biological last 30 modern sheep farming marked, drastic changes diatom taxa, δ 13 15 isotopic ratios, a sharp increase...
Abstract. Soil water availability deeply affects plant physiology. In viticulture it is considered as a major contributor to the "terroir" expression. The assessment of soil in field conditions difficult task especially over large surfaces. New techniques, are therefore required better explore variations content space and time with low disturbance great precision. Electrical Resistivity Tomography (ERT) meets these requirements, for applications sciences, agriculture ecology. this paper,...
Most of the aquatic vegetation produces organic substances via C3 photosynthetic pathway (mosses, isoetids-
In a climate change scenario, successful modeling of the relationships between plant-soil-meteorology is crucial for sustainable agricultural production, especially perennial crops. Grapevines (Vitis vinifera L. cv Chardonnay) located in eight experimental plots (Burgundy, France) along hillslope were monitored weekly three years leaf water potentials, both at predawn (Ψpd) and midday (Ψstem). The stress experienced by grapevine was modeled as function meteorological data (minimum maximum...
