Much of what we know about speciation comes from detailed studies of well‐known model
systems. Although there have been several important syntheses on speciation, few (if any) …

The order Hymenoptera (wasps, ants, sawflies, and bees) represents one of the most
diverse animal lineages, but whether specific key innovations have contributed to its …

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

Chalcidoidea are mostly parasitoid wasps that include as many as 500 000 estimated
species. Capturing phylogenetic signal from such a massive radiation can be daunting …

Banyan trees are distinguished by their extraordinary aerial roots. The Ficus genus includes
species that have evolved a species-specific mutualism system with wasp pollinators. We …

The animal gut is a habitat for diverse communities of microorganisms (microbiota).
Honeybees and bumblebees have recently been shown to harbour a distinct and species …

Background Next-generation sequencing technologies are rapidly generating whole-
genome datasets for an increasing number of organisms. However, phylogenetic …

Studies investigating the evolution of flowering plants have long focused on isolating
mechanisms such as pollinator specificity. Some recent studies have proposed a role for …

Hemiepiphytic plants are defined by their ontogeny. They germinate on a host tree but later
establish root contact with the soil. Most hemiepiphytes remain structurally dependent on …

Abstract In macroevolution, the Red Queen (RQ) model posits that biodiversity dynamics
depend mainly on species-intrinsic biotic factors such as interactions among species or life …
