Stability and the competition-dispersal trade-off as drivers of speciation and biodiversity gradients
Frontiers in Ecology and Evolution
The geography of speciation is one of the most contentious topics at the frontier between ecology and evolution. Here, building on previous hypotheses, I propose that ecological constraints on species co-existence mediate the likelihood of speciation, via a trade-off between competitive and dispersal abilities. Habitat stability, as found in the tropics, selects for the evolution of stronger competitive abilities. Since resource investment in competitive and dispersal abilities should tradedoi:10.3389/fevo.2015.00052 fatcat:tatziurux5aolda6pktl67ioci
