We consider a spatial (line) model for invasion of a population by a single mutant with a stochastically selectively neutral fitness landscape, independent from the fitness landscape for non-mutants. This model is similar to those considered in Farhang-Sardroodi et al. [PLOS Comput. Biol., 13(11), 2017; J. R. Soc. Interface, 16(157), 2019]. We show that the probability of mutant fixation in a population of size $N$ is greater than $1/N$, which would be the case if there were no variation in… Expand

The effect of spatial randomness on the average fixation time of mutants
This work investigates the effect of spatial randomness on the mean conditional fixation time of mutants in a constant population of cells, N, and finds that randomness has a strong impact on fixation time. Expand
Environmental Variability Promotes Coexistence in Lottery Competitive Systems
The analysis confirms the view that coexistence can occur in a system where space is allocated largely at random, provided environmental variability is sufficiently great (Sale 1977); but the explanations and predictions differ in detail with those of Sale. Expand
Environmental spatial and temporal variability and its role in non-favoured mutant dynamics
This paper considers both birth–death (BD) or death–birth (DB) Moran processes, which are set up on a circular or a complete graph, and investigates spatial and temporal variability affecting division and/or death parameters. Expand
Species coexistence and self-organizing spatial dynamics
IN a patchy environment, dispersal between neighbouring local populations can allow the total (regional) population to persist1–5; even where all patches are identical and the within-patch dynamicsExpand
An expanded modern coexistence theory for empirical applications.
This work presents a general computational approach that extends the previous solution for the storage effect to all of standard MCT's spatial and temporal coexistence mechanisms, and also process-defined mechanisms amenable to direct study such as resource partitioning, indirect competition, and life history trade-offs.

Sources, Sinks, and Population Regulation
If the surplus population of the source is large and the per capita deficit in the sink is small, only a small fraction of the total population will occur in areas where local reproduction is sufficient to compensate for local mortality, and the realized niche may be larger than the fundamental niche.

Self-generated diversity produces "insurance effects" in biofilm communities.
It is shown that the opportunistic pathogen Pseudomonas aeruginosa undergoes extensive genetic diversification during short-term growth in biofilm communities, suggesting that self-generated diversity in biofilms provides a form of biological insurance that can safeguard the community in the face of adverse conditions.

Ecology, genetics, and evolution of metapopulations
This book discusses metapopulation dynamics in changing environments, including butterfly responses to habitat and climate change, and the consequences of source-sink population dynamics. Expand
Universality of the asymptotics of the one-sided exit problem for integrated processes
We consider the one-sided exit problem for (fractionally) integrated random walks and L\'evy processes. We prove that the rate of decrease of the non-exit probability -- the so-called survivalExpand
Random Walk: A Modern Introduction
This text meets the need for a modern reference to the detailed properties of an important class of random walks on the integer lattice and is suitable for probabilists, mathematicians working in related fields, and for researchers in other disciplines who use random walks in modeling. Expand
