Whether interspecific hybridization is important as a mechanism that generates biological
diversity is a matter of controversy. Whereas some authors focus on the potential of …

Density-dependent processes play a key role in the spatial structuring of biodiversity.
Specifically, interrelated demographic processes, such as gene surfing, high-density …

Modern attempts to produce biogeographic maps focus on the distribution of species, and
the maps are typically drawn without phylogenetic considerations. Here, we generate a …

Phylogeography is a discipline concerned with various relationships between gene
genealogies—phylogenetics—and geography. The word “phylogeography” was coined in …

Astraptes fulgerator, first described in 1775, is a common and widely distributed neotropical
skipper butterfly (Lepidoptera: Hesperiidae). We combine 25 years of natural history …

Phylogenetic trees in insects are frequently dated by applying a “standard” mitochondrial
DNA (mtDNA) clock estimated at 2.3% My− 1, but despite its wide use reliable calibration …

Many hypotheses have been proposed to explain high species diversity in Amazonia, but
few generalizations have emerged. In part, this has arisen from the scarcity of rigorous tests …

A fully updated guide to the increasingly prevalent use of molecular data in ecological
studies Molecular ecology is concerned with how molecular biology and population genetics …

Evolutionary theory has gained tremendous insight from studies of adaptive radiations. High
rates of speciation, morphological divergence, and hybridization, combined with low …

For over half a century, it has been known that the rate of morphological evolution appears
to vary with the time frame of measurement. Rates of microevolutionary change, measured …
