Phenotypic plasticity promotes species coexistence

Nature Ecology & Evolution, 2022
Ecological explanations for species coexistence assume that species' traits, and therefore the differences between species, are fixed on short timescales. However, species' traits are not fixed, but can instead change rapidly as a consequence of phenotypic plasticity.

Intraspecific Variation and Species Coexistence

The American Naturalist, 2007
We use a two-species model of plant competition to explore the effect of intraspecific variation on community dynamics. The competitive ability ("performance") of each individual is assigned by an independent random draw from a species-specific probability distribution.

On the Origin of Coexisting Species

Trends in Ecology & Evolution, 2021
Speciation is frequently initiated but rarely completed, a phenomenon hypothesized to arise due to the failure of nascent lineages to persist. Although a failure to persist often has ecological causes, key gaps exist between ecological and evolutionary theories that, if filled, would clarify when and why speciation succeeds or fails.

Competitive Intransitivity Promotes Species Coexistence

The American Naturalist, 2006
Using 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 ...

Phenotypic Plasticity and Species Coexistence

Trends in Ecology & Evolution, 2016
Ecologists are increasingly interested in predicting how intraspecific variation and changing trait values impact species interactions and community composition. For many traits, much of this variation is caused by phenotypic plasticity, and thus the impact of plasticity on species coexistence deserves robust quantification.

Species Differences in Phenology Shape Coexistence

The American Naturalist, 2020
Ecological 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 cryptic species

Ecology Letters, 2004
AbstractRecent discovery of cryptic species in fig‐pollinating wasps creates a puzzle for the ecological competition theory: how do two or more apparently identical species coexist? Conventional theory predicts that they should not. Chesson (Trends Ecol.

Reconciling empirical interactions and species coexistence

Ecology Letters, 2019
AbstractCoexistence 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.
