Speciation remains a central enigma in biology, and nowhere is this more apparent than in
shallow tropical seas where biodiversity rivals that of tropical rainforests. Obvious barriers to …

The importance of islands in revealing evolutionary processes was highlighted already at
the birth of evolutionary biology as a science (Darwin 1859; Darwin and Wallace 1858) …

DNA barcoding has attracted attention because it is a potentially simple and universal
method for taxonomic assignment. One anticipated problem in applying the method to …

Molecular studies reveal highly ordered geographic patterns in plant and animal
distributions. The tropics illustrate these patterns of community immobilism leading to …

Some of the best evidence for rapid evolutionary change comes from studies of
archipelagos and oceanic islands. City parks are analogous systems as they create …

Although many classic radiations on islands are thought to be the result of repeated lineage
splitting, the role of past fusion is rarely known because during these events, purebreds are …

It is well known that land snails can be dispersed by birds, both by attachment to the body
(ectozoochory) and by passing intact and alive through the bird's digestive tract …

Nations have recently committed to protecting 20–30% of the ocean at various global
summits; however, marine protected areas currently cover< 3% of the ocean. Large‐scale …

In this contribution, the aspects of reptile and amphibian speciation that emerged from
research performed over the past decade are reviewed. First, this study assesses how …

Species flocks are proliferations of closely-related species, usually after colonization of
depauperate habitat. These radiations are abundant on oceanic islands and in ancient …
