▪ Abstract An important aim of plant ecology is to identify leading dimensions of ecological
variation among species and to understand the basis for them. Dimensions that can readily …

Abstract The Paleocene-Eocene Thermal Maximum (PETM) hyperthermal,~ 56 million years
ago (Ma), is the most dramatic example of abrupt Cenozoic global warming. During the …

The geological record encodes the relationship between climate and atmospheric carbon
dioxide (CO2) over long and short timescales, as well as potential drivers of evolutionary …

The end-Cretaceous event was catastrophic for terrestrial communities worldwide, yet its
long-lasting effect on tropical forests remains largely unknown. We quantified plant …

The early Eocene (56 to 48 million years ago) is inferred to have been the most recent time
that Earth's atmospheric CO 2 concentrations exceeded 1000 ppm. Global mean …

Leaf size varies by over a 100,000-fold among species worldwide. Although 19th-century
plant geographers noted that the wet tropics harbor plants with exceptionally large leaves …

Community assembly processes are thought to shape the mean, spread, and spacing of
functional trait values within communities. Two broad categories of assembly processes …

Paleobotanists have long used models based on leaf size and shape to reconstruct
paleoclimate. However, most models incorporate a single variable or use traits that are not …

Leaf size and venation show remarkable diversity across dicotyledons, and are key
determinants of plant adaptation in ecosystems past and present. Here we present global …

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 …
