Modeling soil metabolic processes using isotopologue pairs of position-specific 13C-labeled glucose and pyruvate
Most organic carbon (C) in soils eventually turns into CO2 after passing through microbial metabolic pathways, while providing cells with energy and biosynthetic precursors. Therefore, detailedExpand

Phosphorus and soil development: does the Walker and Syers model apply to semiarid ecosystems?
The Walker and Syers model of phosphorus (P) transformations during pedogenesis is widely accepted for the development of humid ecosystems, but long-term P dynamics of more arid ecosystems remainExpand

Realistic plant species losses reduce invasion resistance in a California serpentine grassland
Summary 1. The majority of experiments examining effects of species diversity on ecosystem functioning have randomly manipulated species richness. More recent studies demonstrate that realisticExpand

Carbon and nitrogen elemental and isotopic patterns in macrofungal sporocarps and trees in semiarid forests of the south‐western USA
Summary 1Previous studies in humid forests have shown that the 13C and 15N isotopic composition differs between ectomycorrhizal (ECM) and saprotrophic (SAP) fungi, and that this ECM–SAP ‘divide’ mayExpand

Soil responses to management, increased precipitation, and added nitrogen in ponderosa pine forests.
Forest management, climatic change, and atmospheric N deposition can affect soil biogeochemistry, but their combined effects are not well understood. We examined the effects of water and N amendmentsExpand

Baseline and projected future carbon storage and carbon fluxes in ecosystems of Hawai‘i
This is the fifth regional report produced by the U.S. Geological Survey (USGS) as part of the national LandCarbon program (https://www2.usgs.gov/climate_landuse/land_ carbon/). As with priorExpand

Probing carbon flux patterns through soil microbial metabolic networks using parallel position-specific tracer labeling
In order to study controls on metabolic processes in soils, we determined the dynamics of 13 CO2 production from two position-specific 13 C-labeled pyruvate isotopologues in the presence and absenceExpand

Simulated nitrogen deposition enhances the performance of an exotic grass relative to native serpentine grassland competitors
Previous research suggests that atmospheric nitrogen (N) deposition may facilitate the invasion and persistence of exotic plant species in serpentine grasslands, but the relative impact of increasedExpand

Does dissolved organic carbon regulate biological methane oxidation in semiarid soils?
In humid ecosystems, the rate of methane (CH4 ) oxidation by soil-dwelling methane-oxidizing bacteria (MOB) is controlled by soil texture and soil water holding capacity, both of which limit theExpand

Flowering phenology shifts in response to biodiversity loss
Significance Advanced spring flowering has been described as a fingerprint of climate change—a public, visible display of the detrimental effects of global warming. However, warming experiments failExpand
