Abstract The Channeled Scabland of eastern Washington State, USA, brought megafloods
to the scientific forefront. A 30,000-km 2 landscape of coulees and cataracts carved into the …

The cause, or causes, of the Pleistocene megafaunal extinctions have been difficult to
establish, in part because poor spatiotemporal resolution in the fossil record hinders …

Loss of megafauna, an aspect of defaunation, can precipitate many ecological changes over
short time scales. We examine whether megafauna loss can also explain features of lasting …
