Pollination and evolution

TL;DR: In this article, the authors used demographic models to understand the population viability of Furbish's lousewort, Pedicularis furbishiae, a perennial plant species endemic to the St. John River Valley in northern Maine.

TL;DR: The strong convergent evolution evident in bird-pollinated flowers raises a question about the nature of the genetic mechanisms underlying such transitions and whether the same gene systems are involved in most cases.

TL;DR: This review attempts a synthesis of the recent literature on selectivity in pollinator foraging behaviour, in terms of the species, patch and individual flowers that they choose to visit, so that foragers can respond to the pattern of rewards that they encounter.

TL;DR: This work reconstructs the historical distribution of bumble bees in a temporal framework, estimating divergence times using fossil data and molecular rates derived from the literature, and reveals movements of Bombus concordant with geographic and climatic events of the late Cenozoic.
