Coexistence under positive frequency dependence.
Negative frequency dependence resulting from interspecific interactions is considered a driving force in allowing the coexistence of competitors. While interactions between species and genotypes can also result in positive frequency dependence, positive frequency dependence has usually been credited with hastening the extinction of rare types and is not thought to contribute to coexistence. In ...
متن کاملCan positive frequency dependence facilitate plant coexistence?
In his opinion piece, Pauw [1] advocated a niche theoretical approach for studying the coexistence of plant species that differ in pollinator use, but are otherwise ecologically equivalent. By treating pollinators as a resource, one can apply the conceptual framework of the Lotka–Volterra model, which shows that coexistence can occur when each species limits its own growth rate more than that o...
متن کاملWhen rarity has costs: coexistence under positive frequency-dependence and environmental stochasticity
Stable coexistence relies on negative frequency-dependence, in which rarer species invading a patch benefit from a lack of conspecific competition experienced by residents. In nature, however, rarity can have costs, resulting in positive frequency-dependence particularly when species are rare. Many processes can cause positive frequency-dependence, including a lack of mates, mutualist interacti...

متن کاملPlant-soil feedbacks promote negative frequency dependence in the coexistence of two aridland grasses.
Understanding the mechanisms of species coexistence is key to predicting patterns of species diversity. Historically, the ecological paradigm has been that species coexist by partitioning resources: as a species increases in abundance, self-limitation kicks in, because species-specific resources decline. However, determining coexistence mechanisms has been a particular puzzle for sedentary orga...
