New Zealand has long been a conundrum to biogeographers, possessing as it does
geophysical and biotic features characteristic of both an island and a continent. This schism …

New Zealand biogeography has been dominated by the knowledge that its geophysical
history is continental in nature. The continental crust (Zealandia) from which New Zealand is …

Frogs (Anura) are one of the most diverse groups of vertebrates and comprise nearly 90% of
living amphibian species. Their worldwide distribution and diverse biology make them well …

The evidentiary basis of the currently accepted classification of living amphibians is
discussed and shown not to warrant the degree of authority conferred on it by use and …

Amphibia comprises over 7000 extant species distributed in almost every ecosystem on
every continent except Antarctica. Most species also show high specificity for particular …

Dating the tree of life is a core endeavor in evolutionary biology. Rates of evolution are
fundamental to nearly every evolutionary model and process. Rates need dates. There is …

The fossil record of modern amphibians (frogs, salamanders, and caecilians) provides no
evidence for major extinction or radiation episodes throughout most of the Mesozoic and …

Most extant genus-level radiations in gymnosperms are of Oligocene age or younger,
reflecting widespread extinction during climate cooling at the Oligocene/Miocene boundary …

How should characters and taxa be sampled to resolve efficiently the phylogeny of ancient
and highly speciose groups? We addressed this question empirically in the treefrog family …

Abstract The Late Cretaceous was a time of tremendous global change, as the final stages
of the Age of Dinosaurs were shaped by climate and sea level fluctuations and witness to …
