In most places on Earth, many similar species are found coexisting. This key observation is often explained in terms of ecological differences in how species interact with their shared environment, that is, in terms of their niche differences. Niche differences can to lead to stable coexistence in contrast to the ecological drift predicted by the ...

Reconciling empirical interactions and species coexistence
Ecology Letters, 2019AbstractCoexistence in ecological communities is governed largely by the nature and intensity of species interactions. Countless studies have proposed methods to infer these interactions from empirical data, yet models parameterised using such data often fail to recover observed coexistence patterns.

Coexistence of species in a defensive switching model
Mathematical Biosciences, 2003We consider a simple mathematical model of two-predators and one-prey system which has the defensive switching property of predation-avoidance. We assume that the prey remains vigilant against relatively abundant predator species and guards against it by switching to another (relatively rare) predator species.

Species Differences in Phenology Shape Coexistence
The American Naturalist, 2020Ecological theory produces opposing predictions about whether differences in the timing of life-history transitions, or "phenology," promote or limit coexistence. Phenological separation is predicted to create temporal niche differences, increasing coexistence, yet phenological separation could also competitively favor one species, increasing fitness ...

Coexistence of many species in random ecosystems
Nature Ecology & Evolution, 2018Rich ecosystems harbour thousands of species interacting in tangled networks encompassing predation, mutualism and competition. Such widespread biodiversity is puzzling, because in ecological models it is exceedingly improbable for large communities to stably coexist.

Competitive Intransitivity Promotes Species Coexistence
The American Naturalist, 2006Using a spatially explicit cellular automaton model with local competition, we investigate the potential for varied levels of competitive intransitivity (i.e., nonhierarchical competition) to promote species coexistence. As predicted, on average, increased levels of intransitivity result in more sustained coexistence within simulated communities ...

Disturbances and Coexistence of Species
2016Some conceptual models have been proposed to attempt an explanation of the mechanisms of coexistence of species groups inside environmental systems subjected to disturbances. Some of these models emphasize the role disturbances (and, more specifically, their regimen) may have in maintaining or altering the diversity of species observed in the ...

Intraspecific Adaptation Load: A Mechanism for Species Coexistence
Trends in Ecology & Evolution, 2020Evolutionary ecological theory suggests that selection arising from interactions with conspecifics, such as sexual and kin selection, may result in evolution of intraspecific conflicts and evolutionary 'tragedy of the commons'. Here, we propose that such an evolution of conspecific conflicts may affect population dynamics in a way that enhances species

Coexistence of species competing for shared resources
Theoretical Population Biology, 1976Abstract In this paper we develop a mathematical model in which any number of competing species can coexist on four resources which regenerate according to an algebraic relationship. We show that previous attempts to prove that n species cannot coexist on fewer that n resources (the “competitive exclusion principle”) all make use of the very ...

Coexistence of competing species by the oscillation of polymorphisms
Journal of Theoretical Biology, 2005Scale-eating cichlids in Lake Tanganyika exhibit genetically determined lateral asymmetry, especially in their mouth-opening. Frequencies of the morphs oscillate due to strong frequency-dependent selection caused by the switching of prey's attention, and its delayed effect by their growth period.
