Neutral theories have played a crucial and revolutionary role in fields such as population genetics and biogeography. These theories are critical by definition, in the sense that the overall growth rate of each single allele/species/type vanishes. Thus each species in a neutral model sits at the edge between invasion and extinction, allowing for the coexistence of symmetric/neutral types. However, in finite systems, mono-dominated states are ineluctably reached in relatively short times owing…

The advantage of being slow: The quasi-neutral contact process
TLDR
This work examines competitive advantage in the context of quasi-neutral population models, including stochastic models with spatial structure as well as macroscopic (mean-field) descriptions, and finds that a species with a slower biological clock has an advantage if resources are limited, winning the competition against aspecies with a faster clock, in relatively small systems.
Stochastic Spatial Models in Ecology: A Statistical Physics Approach
TLDR
This review discusses the state of the art in spatial neutral theory, and focuses on non-trivial scaling laws arising at the critical dimension $$D = 2$$D=2 of spatial neutral models, and their relevance for biological populations inhabiting two-dimensional environments.

Characterization of the Nonequilibrium Steady State of a Heterogeneous Nonlinear $q$-Voter Model with Zealotry
TLDR
This work focuses on the characterization of the model's non-equilibrium stationary state (NESS) in terms of its probability distribution and currents in the distinct regimes of low and high density of zealotry, by computing the opinion distribution and the circulation of probability currents.

Neutral theory and relative species abundance in ecology
TLDR
A theoretical framework for the unified neutral theory of biodiversity and an analytical solution for the distribution of the RSA both in the metacommunity (Fisher's log series) and in the local community, where there are fewer rare species.

Density dependence explains tree species abundance and diversity in tropical forests
TLDR
It is shown that the framework of the current neutral theory in ecology can easily be generalized to incorporate symmetric density dependence and precisely the strength of the rare-species advantage that is needed to explain a given RSA distribution is calculated.
Spontaneously broken neutral symmetry in an ecological system.
TLDR
It is demonstrated that dynamical evolution can lead to a stationary state characterized simultaneously by both biodiversity and spontaneously broken neutral symmetry.

Quasi-Neutral Theory of Epidemic Outbreaks
TLDR
It is shown that the theory of accidental pathogens is a (quasi) neutral model, analogous to those used in Population Genetics and Ecology, with the same critical behavior as the voter-model, which allows the system phenomenology, including generic scale invariance and the associated scaling exponents, to be explained in a parsimonious and simple way.

▪ Abstract Edge effects have been studied for decades because they are a key component to understanding how landscape structure influences habitat quality. However, making sense of the diverse
Habitat destruction and the extinction debt
TLDR
A model is described that explains multispecies coexistence in patchy habitats and which predicts that their abundance may be fleeting, a future ecological cost of current habitat destruction.

TLDR
The dynamics of the voter model and of the monomer-monomer catalytic process in the presence of many "competing" inhomogeneities are considered and it is shown that their presence results in a non-trivial fluctuating steady state whose properties turn out to specifically depend on the dimensionality of the system, the strength of the inhomogenities, and their separating distances.
