Biodiversity today has the unusual property that 85% of plant and animal species live on
land rather than in the sea, and half of these live in tropical rainforests. An explosive boost to …

During the Paleocene-Eocene Thermal Maximum (PETM),∼ 56 Mya, thousands of
petagrams of carbon were released into the ocean-atmosphere system with attendant …

The world's most revered and eloquent interpreter of evolutionary ideas offers here a work of
explanatory force unprecedented in our time—a landmark publication, both for its historical …

Our ability to correlate biological evolution with climate change, geological evolution, and
other historical patterns is essential to understanding the processes that shape biodiversity …

Mammals are the most encephalized vertebrates, with the largest brains relative to body
size. Placental mammals have particularly enlarged brains, with expanded neocortices for …

The stable isotope compositions of biogenic materials record a combination of
environmental parameters and biological processes. In general, the environment provides a …

Water plays a critical role in erosion and sediment transport and this relationship is most
evident in the hyperarid Atacama Desert of Northern Chile, a region characterized by …

Abstract CHANGES in the isotope content of the large marine carbon reservoir can force
shifts in that of the smaller carbon pools in the atmosphere and on land. The carbon isotope …

Rapid global warming of 5° to 10° C during the Paleocene-Eocene Thermal Maximum
(PETM) coincided with major turnover in vertebrate faunas, but previous studies have found …

Detailed investigations of high latitude sequences recently collected by the Ocean Drilling
Program (ODP) indicate that periods of rapid climate change often culminated in brief …
