Will sympatric speciation fail due to stochastic competitive exclusion?
Sympatric speciation requires coexistence of the newly formed species. If divergence proceeds by small mutational steps, the new species utilize almost the same resources initially, and full speciation may be impeded by competitive exclusion in stochastic environments. We investigate this primarily ecological problem of sympatric speciation by studying the population dynamics of a diverging ase...
متن کاملComplex food webs prevent competitive exclusion among producer species.
Herbivorous top-down forces and bottom-up competition for nutrients determine the coexistence and relative biomass patterns of producer species. Combining models of predator-prey and producer-nutrient interactions with a structural model of complex food webs, I investigated these two aspects in a dynamic food-web model. While competitive exclusion leads to persistence of only one producer speci...
متن کاملCompetitive supply of durable goods under stochastic fluctuation in stock
This paper presents a theoretical model in which the stock growth rate of durable goods has stochastic fluctuation over time. It concludes that a social planner increases the expected percentage rate of production since uncertainty increases the user cost from consumer’s point view.

متن کاملNeanderthal Extinction by Competitive Exclusion
BACKGROUND Despite a long history of investigation, considerable debate revolves around whether Neanderthals became extinct because of climate change or competition with anatomically modern humans (AMH). METHODOLOGY/PRINCIPAL FINDINGS We apply a new methodology integrating archaeological and chronological data with high-resolution paleoclimatic simulations to define eco-cultural niches associ...
