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 کاملPositive climate feedbacks of soil microbial communities in a semi-arid grassland.
Soil microbial communities may be able to rapidly respond to changing environments in ways that change community structure and functioning, which could affect climate-carbon feedbacks. However, detecting microbial feedbacks to elevated CO(2) (eCO(2) ) or warming is hampered by concurrent changes in substrate availability and plant responses. Whether microbial communities can persistently feed ...
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 کاملDifferent Fire Frequency Impacts Over 27 Years on Vegetation Succession in an Infertile Old-Field Grassland
We examined the effect of fire on vegetation composition with the use of an experiment with four different fire frequencies (annual, 2-yr interval, 4-yr interval, and an intended control with no burning) over a 27-yr period in an infertile, old-field grassland at the Cedar Creek Ecosystem Science Reserve, located in Minnesota, United States. We measured the plant species’ aboveground biomass in...
