Rates of speciation and extinction are often linked to many ecological factors, traits
(emergent and nonemergent) such as environmental tolerance, body size, feeding type, and …

Mass extinctions are known to be extraordinary events during which the normal rules of
natural selection do not apply. Evidence points to the operation of a different selective …

Mass extinctions have altered the trajectory of evolution a number of times over the
Phanerozoic. During these periods of biotic upheaval a different selective regime appears to …

The isolation of Zealandia in the latest Cretaceous and early Paleogene following the final
break-up of Gondwana fostered significant provincialism in molluscan faunas, concomitant …

Factors shaping the geographic range of a species can be identified when phylogeographic
patterns are combined with data on contemporary and historical geographic distribution …

Conservation biologists and palaeontologists are increasingly investigating the phylogenetic
distribution of extinctions and its evolutionary consequences. However, the dearth of …

The Lower Tertiary Gulf Coast was subjected to repeated transgressive-regressive cycles of
varying rate and extent which had a marked effect on species longevities. In some …

Genera by their very nature are expected to be monotypic and geographically and
environmentally restricted at their origin, and most genera do not endure past their stage of …

We use the trace-fossil record left by the shell-drilling and crushing predators of marine
mollusks to investigate the paleoecology of mass extinction. The pulsed extinction of …

Raphidioptera, the group of snakeflies, is a rather species-poor in-group of Holometabola.
Yet, fossils of snakeflies indicate that the group was more diverse in the past. Here we …
