Deterministic models of vegetation often summarize, at a macroscopic scale, a multitude of intrinsically random events occurring at a microscopic scale. We bridge the gap between these scales by demonstrating convergence to a mean-field limit for a general class of stochastic models representing each individual ecological event in the limit of large system size. The proof relies on classical stochastic coupling techniques that we generalize to cover spatially extended interactions. The mean…

Unifying deterministic and stochastic ecological dynamics via a landscape-flux approach

The ecodynamics of a forest–savanna model under fluctuations via a landscape-flux theoretical framework from nonequilibrium statistical physics is studied and it is found that the average flux, entropy production rate, and free energy have significant changes near bifurcations under both finite and zero fluctuation.

Impulsive Fire Disturbance in a Savanna Model: Tree–Grass Coexistence States, Multiple Stable System States, and Resilience

It is found that large transitions (“tipping”) in the valued quantity can be triggered by small changes in disturbance regime and the resilience of the social value to different disturbance regimes is examined.

Population model of Temnothorax albipennis as a distributed dynamical system: I. self-consistent threshold is an emergent property in combination of quorum sensing and chemical perception of limited resource

This work borrows the idea from bacteria quorum sensing to clarify the definition of quorum threshold through biological plausible mechanism related to limited resource model, and makes use of the contraction analysis to explore the trade-off between decision split and decision consensus within ant population.



On the complex dynamics of savanna landscapes

Analysis of a set of simple, yet realistic, models for savanna–forest vegetation dynamics based on minimal ecological assumptions reveals that diverse cyclic behaviors occur for broad ranges of parameter space and that large shifts in landscape structure can result from endogenous dynamics and not just from external drivers or from noise.

Tropical tree cover in a heterogeneous environment: A reaction-diffusion model

The Maxwell point of the homogeneous reaction-diffusion equation without savanna trees is derived and it is shown that the front between forest and nonforest settles at this point as long as savanna tree cover near the front remains sufficiently low.

Mean field limit for disordered diffusions with singular interactions

Motivated by considerations from neuroscience (macroscopic behavior of large ensembles of interacting neurons), we consider a population of mean field interacting diffusions in $\mathbf {R}^m$ in the

Propagation of chaos in neural fields

The propagation of chaos property is proved in this setting under mild assumptions on the neuronal dynamics, valid for most models used in neuroscience, in a mesoscopic limit, the neural-field limit, in which the authors can resolve quite fine structure of the neuron's activity in space and where averaging effects occur.

Allee Effects, Invasion Pinning, and Species’ Borders

The properties of invasion models when a species cannot persist below a critical population density known as an “Allee threshold” are studied, suggesting caution when interpreting abrupt range limits as stemming either from competition between species or a hard environmental limit that cannot be crossed.

Spatial feedbacks and the dynamics of savanna and forest

Theoretical models and empirical analyses have combined to suggest that, for some ranges of climate, alternative stable states in vegetation structure may be possible: positive feedbacks with fire

Transient phenomena in ecology

Current knowledge of transient dynamics is reviewed, showing that hitherto idiosyncratic and individual patterns can be classified into a coherent framework, with important general lessons and directions for future study.

Dispersal increases the resilience of tropical savanna and forest distributions

This work examines the contributions of dispersal to determining savanna and forest distributions using a reaction-diffusion model, and suggests that both models are limited in that they ignore spatial processes, such as dispersal.

Seed Dispersal Near and Far: Patterns Across Temperate and Tropical Forests

Dispersal affects community dynamics and vegetation response to global change. Understanding these effects requires descriptions of dispersal at local and regional scales and statistical models that

Spatial aspects of interspecific competition.

It is proved rigorously that if one species has a competitive advantage over each of the others, then eventually it takes over all the sites in the system and produces a stationary distribution with an interesting spatial structure.
