Soil nitrogen (N) is an important component in maintaining ecosystem stability, and the introduction of non-native plants can alter N cycling by changing litter quality and quantity, nutrient uptake patterns, and soil food webs. Our goal was to determine the effects of Bromus tectorum (C3) invasion on soil microbial N cycling in adjacent non-invaded and invaded C3 and C4 native arid grasslands. We monitored resin-extractable N, plant and soil δ13C and δ15N, gross rates of inorganic N… 

Response of the soil microbial community composition and biomass to a short-term Spartina alterniflora invasion in a coastal wetland of eastern China

AimsPlant invasion has been reported to alter ecosystem carbon (C) and nitrogen (N) cycling processes and pools. The mechanisms involved in how plant invasion affects the soil microbial community—the

The invasive annual cheatgrass increases nitrogen availability in 24-year-old replicated field plots

Previous studies comparing invaded and non-invaded sites suggest that cheatgrass (Bromus tectorum L.) causes soil N cycling to increase. Unfortunately, these correlative studies fail to distinguish

The Influence of Plant-Soil Interactions on Plant and Soil Microbial Responses to Nitrogen Deposition

A common response of plant communities to increased nitrogen (N) deposition is a shift in species’ abundances. Multiple factors have been proposed to explain the changes in abundance, notably

Soil–plant N processes in a High Arctic ecosystem, NW Greenland are altered by long‐term experimental warming and higher rainfall

The findings indicate that warmer, wetter High Arctic tundra will be cycling N and C in ways that may transform these landscapes in part leading to greater C sequestration, but simultaneously, N losses from the upper soil profile that may be transported to depth dissolved in water and or transported off site in lateral flow.

Linkages of litter and soil C:N:P stoichiometry with soil microbial resource limitation and community structure in a subtropical broadleaf forest invaded by Moso bamboo

Invasive plants not only alter aboveground biodiversity but also belowground microbial community composition to facilitate their growth and competitiveness. However, how plant invasion affects soil

Plant-soil feedbacks and invasion in sagebrush steppe ecosystems

Invasion by non-native species is a serious ecological threat and the susceptibility of ecosystems to invasion is often highly correlated with soil resource availability. Understanding the role of


ABSTRACT The function and change of global soil carbon (C) reserves in natural ecosystems are key regulators of future carbon-climate coupling. Microbes play a critical role in soil carbon cycling

The invasive annual cheatgrass releases more nitrogen than crested wheatgrass through root exudation and senescence

The results provide the first evidence for the underlying mechanism by which the invasive annual cheatgrass increases N availability and establishes positive plant-soil feedbacks that promote its success in western rangelands.




The introduction of nonnative plant species may decrease ecosystem stability by altering the availability of nitrogen (N) for plant growth. Invasive species can impact N availability by changing

Pulse additions of soil carbon and nitrogen affect soil nitrogen dynamics in an arid Colorado Plateau shrubland

It is observed that increases in available C lead to greater ecosystem immobilization and retention of N in soil microbial biomass and also lowered rates of gaseous N loss, which has implications for the competitive relationships between plants species, plants and microbes, or both.

Bromus tectorum invasion alters nitrogen dynamics in an undisturbed arid grassland ecosystem.

It is suggested that invasion has altered the mechanisms driving nitrogen dynamics in recently invaded, undisturbed vegetation associations, resulting in reduced total soil N in the invaded/disturbed communities.

Effects of Exotic Plant Invasions on Soil Nutrient Cycling Processes

This work has reviewed studies that compare pool sizes and flux rates of the major nutrient cycles in invaded and noninvaded systems for invasions of 56 species and suggests that invasive plant species frequently increase biomass and net primary production, increase N availability, alter N fixation rates, and produce litter with higher decomposition rates than co-occurring natives.

The Influence of Soil Inoculum and Nitrogen Availability on Restoration of High‐Elevation Steppe Communities Invaded by Bromus tectorum

Soil inoculum additions and reduced N availability both contributed toward restoring a perennial-dominated community and demonstrates that addition of native soil inoculum may be a useful tool for restoration efforts.

Soil biota can change after exotic plant invasion: Does this affect ecosystem processes?

Invasion of the exotic annual grass Bromus tectorum into stands of the native perennial grass Hilaria jamesii significantly reduced the abundance of soil biota, especially microarthropods and nematodes, although populations generally increased after 50+ years of invasion.

Comparison of Soil Bacterial Communities in Rhizospheres of Three Plant Species and the Interspaces in an Arid Grassland

This study provides a baseline for monitoring bacterial community structure and dynamics with changes in plant cover and environmental conditions in the arid grasslands and identifies broad-scale, consistent differences in the bacterial communities in different soil locations.

Microbial dynamics and carbon and nitrogen cycling following re-wetting of soils beneath two semi-arid plant species

Evidence is provided that the high N availability often associated with wetting ofcheatgrass soils is a result of cheatgrass supplying substrates to microbes that are of high decomposability and N content, which promotes faster N cycling rates and greater N availability.

Microbial community utilization of recalcitrant and simple carbon compounds: impact of oak-woodland plant communities

The results demonstrate that the presence of distinctly different plant communities did not alter the microbial community profile responsible for decomposition of relatively labile C-substrates but did alter the profiles of microbial communities responsible for decompposition of the more recalcitrant substrates, pine litter and indigenous soil organic matter.
