Evidence from field studies suggests that some plant species enhance their persistence by reinforcing patterns of N availability through differences in litter quality. Using mathematical models of nutrient flow, we explore whether and how recycling affects plant growth, competition, and coexistence and whether it leads to positive feedbacks. Two mechanisms are considered: the ability of plants to access two forms of soil N, complex (e.g., organic) and simple (e.g., nitrate), and the effect of… 

Recycling‐Mediated Facilitation and Coexistence Based on Plant Size

The model provides a context where recycling can generate negative feedback between competitors that differ in size and so promote coexistence, opposite to the positive recycling‐mediated feedback commonly expected on the basis of litter chemistry differences between competitors.

Nutrient enrichment and local competition influence the evolution of plant mineralization strategy: a modelling approach

The results suggest that plant mineralization strategy may evolve provided that the mineral resource is not fully shared by all individuals, and shows that evolutionary feedbacks of plants to nutrient enrichment are likely to differ from purely ecological feedbacks.

Grassland establishment under varying resource availability: a test of positive and negative feedback.

In a developing ecosystem, positive feedback between soil N supply and plant productivity may promote enhanced long-term N availability and override progressive N limitation as C accrues in plant and soil pools.

Plant Water Use Affects Competition for Nitrogen: Why Drought Favors Invasive Species in California

It is shown that soil moisture–mediated competition for nitrogen can explain the annual species’ dominance in drier areas, with coexistence expected in wetter regions, and are concordant with larger biogeographic patterns of grassland invasion in the Pacific states of the United States.

Plant Size and Competitive Dynamics along Nutrient Gradients

It is found that invader success and competitive ability are unimodal functions of maximum potential size, such that plants that are too large (or too small) are disproportionately suppressed by competition.

Functional diversity of microbial decomposers facilitates plant coexistence in a plant–microbe–soil feedback model

The results suggest that the microbial community plays a central role in PSF function and the plant community structure, and strongly imply that the plant-centered view of nutrient cycling should be changed to a plant–microbe–soil feedback system.

Creating Invasion Resistant Soils via Nitrogen Management

The overall objective of this review paper is to provide the ecological background of invasion by exotic plants and propose a concept to facilitate the use of soil nitrogen management to achieve desired plant communities that resist invasion.

Incorporating the soil environment and microbial community into plant competition theory

A theoretical framework is presented to illustrate that although the two models for PSF are typically presented separately, their behavior can be understood together by invasibility analysis and suggestions are made for future directions in PSF theoretical studies.

Mechanisms of nutrient limitation and nutrient acquisition in managed and unmanaged forest ecosystems

It is widely accepted that nitrogen limits primary production in temperate forests, although co-limitation by N and P has also been suggested, and on some soils Ca and base cations are in short

The lack of relationship between root biomass and species richness and evenness suggests that, even though root competition in grasslands is intense, belowground interactions may not play an important role in structuring community diversity or composition.

GRAZING OPTIMIZATION AND NUTRIENT CYCLING: WHEN DO HERBIVORES ENHANCE PLANT PRODUCTION?

Grazing optimization is most likely to occur in systems with large losses of the limiting nutrient during recycling of plant detritus, or where herbivores bring nutrient from outside the ecosystem considered (which acts to reduce, or even make negative, the fraction of nutrient lost along the herbivoredetritus pathway).

Effect of Herbivory and Plant Species Replacement on Primary Production

It is shown that two major plant traits determine primary production at equilibrium: plant recycling efficiency and plant ability to deplete the soil mineral nutrient pool through consumption of this resource.

Feedbacks between nutrient cycling and vegetation predict plant species coexistence and invasion

To investigate the role of species-specific litter decomposability in determining plant community structure, we constructed a theoretical model of the codevelopmental dynamics of soil and vegetation.

Plant Community Dynamics, Nutrient Cycling, and Alternative Stable Equilibria in Peatlands

A model of peatlands that constructs and analyze a set of six coupled differential equations that defines the flow of nutrients from moss and vascular plants to their litters, then to peat, and finally to an inorganic nutrient resource pool and allows for an early transient spike in vascular plant dominance followed by approach to near moss monoculture and then eventual approach to coexistence equilibrium.

Interspecific competition in natural plant communities: mechanisms, trade-offs and plant-soil feedbacks

It is argued that selection in nutrient-poor habitats is not necessarily on a high competitive ability for nutrients and a high growth rate, but rather on traits which reduce nutrient losses (low tissue nutrient concentrations, slow tissue turnover rates, high nutrient resorption efficiency).

The results of these experiments suggest that nutrient supplies may significantly affect the competitive dynamics between salt-marsh perennials and their resultant zonation across an environmental gradient in tidal stress.

Species effects on resource supply rates: do they influence competitive interactions?

The results suggest that species effects on supply rates may influence competitive interactions, particularly if these effects are complemented by other sources of temporal or spatial variation such as pulses in resource availability.

The book shows that relative growth rate, which is predicted to be strongly influenced by a plant's proportional allocation to leaves, is a major determinant of the transient dynamics of competition.

Species effects on nitrogen cycling: a test with perennial grasses

If individual plant species can affect N mineralization and N availability, then competition for N may lead to positive or negative feedbacks between the processes controlling species composition and ecosystem processes such as N and C cycling.
