Coevolutionary diversification is cited as a major mechanism driving the evolution of
diversity, particularly in plants and insects. However, tests of coevolutionary diversification …

Events of both hybridization and polyploidy are capable of completely restructuring the
genome, modifying phenotypic traits and affecting ecological interactions. For plants, these …

At a glance, most species seem adapted to the environment in which they live. Yet species
relentlessly evolve, and populations within species evolve in different ways. Evolution, as it …

Coevolutionary interactions between species are thought to be an important cause of
evolutionary diversification. Despite this general belief, little theoretical basis exists for …

Coevolution, reciprocal adaptation between two or more taxa, is commonly invoked as a
primary mechanism responsible for generating much of Earth's biodiversity. This …

Abstract The Mojave Desert contains the hottest, driest regions in North America and is also
one of the most ecologically intact regions in the contiguous United States. However, a …

Coevolution is thought to be especially important in diversification of obligate mutualistic
interactions such as the one between yuccas and pollinating yucca moths. We took a three …

The ways that plant‐feeding insects have diversified are central to our understanding of
terrestrial ecosystems. Obligate nursery pollination mutualisms provide highly relevant …

Brood pollination mutualisms—interactions in which specialized insects are both the
pollinators (as adults) and seed predators (as larvae) of their host plants—have been …

Yucca moths (Tegeticula and Parategeticula) are specialized pollinators of yucca plants,
possessing unique, tentacle-like mouthparts used to actively collect pollen and deposit it …
