Speciation rates for some taxa increase from the poles towards the equator. augmenting the number of species in the tropics. The causes of latitudinal variation in speciation rates are presently unknown. Here we present and discuss the Asynchrony of Seasons Hypothesis that invokes latitudinal differences in the spatial asynchrony of climate. https://www.ngetikin.com/amazing-find-Bolia-Loop-Rug-limited-choice/
