In deterministic approaches to modeling, two species are generally regarded as capable of coexistence if the model has a stable equilibrium with both species in positive numbers. Temporal environmental variability is assumed to reduce the likelihood of coexistence by keeping species abundances away from equilibrium. Here we present a contrasting view based on a model of competition for space among coral reef fishes, or any similarly territorial animals. The model has no stable equilibrium point… Expand
Species coexistence in a neutral dynamics with environmental noise.
TLDR
This paper analyzes the case of two species competing for the resources within the framework of the neutral theory in the presence of environmental noise, devoting special attention on how such a variability modulates species fitness. Expand
Coexistence in a variable environment: eco-evolutionary perspectives.
TLDR
This work extends a well-studied coexistence mechanism depending on resource fluctuations by allowing evolution along a tradeoff between maximum growth rate and competitive ability, and examines how evolutionary forces may alter predicted ecological dynamics. Expand
Species coexistence in a variable world.
TLDR
It is proposed that critical tests for species coexistence must account for niche differentiation arising from this variability and should be based explicitly on notions of stability and ecological drift. Expand
Species coexistence by permanent spatial heterogeneity in a lottery model.
TLDR
It is found that between-habitat variation in the ratio of mortalities of two species promotes coexistence, while that of reproductive rates does not, the opposite of the role of temporal variations in the standard lottery model. Expand
Dispersal, Variability, and Transient Niches: Species Coexistence in a Uniformly Variable Environment
TLDR
It is shown that random environmental variation, with no long-term spatial inhomogeneity (i.e., a uniformly variable environment), can promote species' coexistence in models of lottery competition for establishment sites and infer that the spatial distributions of rarer species in sessile organism guilds may be highly clumped. Expand
Coexistence of competitors in marine metacommunities: environmental variability, edge effects, and the dispersal niche.
TLDR
Investigation of coexistence in spatially homogeneous metacommunities where there is no partitioning of resources, no competition-colonization trade-off, and no possibility of source-sink dynamics demonstrates that a subordinate species may persist by occupying a dispersal niche that differs sufficiently from that of the dominant species.

Coexistence of Competitors in Spatially and Temporally Varying Environments: A Look at the Combined Effects of Different Sorts of Variability
A stochastic model is developed for competition among organisms living in a patchy and varying environment. The model is designed to be suitable for species with sedentary adults and widelyExpand
The Effects of Dynamical Rates on Species Coexistence in a Variable Environment: The Paradox of the Plankton Revisited
TLDR
Fast resource depletion ensures strong coupling of environmental processes and competition, which leads to enhancement over time of intraspecific competition relative to interspecific competition as environmental shifts favor different species at different times. Expand
Coexistence and invasibility in a two-species competition model with habitat-preference.
TLDR
It is shown that invasibility properties depend on habitat preference in a non-trivial way and the neutral model results more invasible or less Invasible depending on whether the comparison is made at equal immigration rate or at equal distribution of population size. Expand
Competition and coexistence: modelling approaches
TLDR
Competition and coexistence are discussed in the framework of multispecies and simple food web models such that inter- and intraspecific interactions of the many species occur via few collective variables. Expand

TLDR
The stability described here is such that the ecosystem will return to the same dynamic balance even when severely perturbed, and can be either favored or prevented in certain cases by random fluctuations in the environment affecting season length, kill factor, etc. Expand

There is an effective limit to niche overlap in the real world, and this limit is insensitive to the degree of environmental fluctuation, unless it be very severe. Expand
Coexistence in a Variable Environment
TLDR
It is shown that there is no long term correlation between the abundance of a species and its rates of increase and the number of consumer species cannot exceed thenumber of resources plus distinct nonlinearities. Expand
Competition and Regional Coexistence
TLDR
A model of the competition between two species is developed and it is found that in some cases it is possible for one species to exclude another species from a geographic region, but there is no possibility of a "priority effect" where the first species in the region can always exclude the other.

TLDR
The general conclusion from the model is that there is an effective limit to niche overlap in the real world, and that this limit is insensitive to the degree of environmental fluctuation, unless it be very severe, which seems in accord with an increasing body of field data. Expand
