Sensitivity of leaf size and shape to climate: global patterns and paleoclimatic applications.
• 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 physiologically orExpand

Sharply increased insect herbivory during the Paleocene–Eocene Thermal Maximum
The Paleocene–Eocene Thermal Maximum (PETM, 55.8 Ma), an abrupt global warming event linked to a transient increase in pCO2, was comparable in rate and magnitude to modern anthropogenic climateExpand

Fossil insect folivory tracks paleotemperature for six million years
Paleoecological studies enhance our understanding of biotic response to climate change because they consider timescales not accessible through laboratory or ecological studies. From 60 to 51 millionExpand

Plant response to a global greenhouse event 56 million years ago.
PREMISE OF THE STUDY The fossil record provides information about the long-term response of plants to CO2-induced climate change. The Paleocene-Eocene Thermal Maximum (PETM), a 200000-yr-long periodExpand

No post-Cretaceous ecosystem depression in European forests? Rich insect-feeding damage on diverse middle Palaeocene plants, Menat, France
Insect herbivores are considered vulnerable to extinctions of their plant hosts. Previous studies of insect-damaged fossil leaves in the US Western Interior showed major plant and insect herbivoreExpand

Patchiness and long-term change in early Eocene insect feeding damage
Abstract Many studies have examined temporal changes in insect feeding on angiosperm leaves, but none have considered variability within a single stratigraphic level. If spatial variability within aExpand

Paleogene plants fractionated carbon isotopes similar to modern plants
The carbon isotope composition (δ13Cδ13C) of terrestrial plant biomarkers, such as leaf waxes and terpenoids, provides insights into past carbon cycling. The δ13Cδ13C values of modern plantExpand

Inferring ecological disturbance in the fossil record: A case study from the late Oligocene of Ethiopia
Abstract Environmental disturbances profoundly impact the structure, composition, and diversity of modern forest communities. A review of modern studies demonstrates that important characteristicsExpand

Cretaceous/Paleogene Floral Turnover in Patagonia: Drop in Diversity, Low Extinction, and a Classopollis Spike
Nearly all data regarding land-plant turnover across the Cretaceous/Paleogene boundary come from western North America, relatively close to the Chicxulub, Mexico impact site. Here, we present aExpand

Cell anatomy and leaf δ13C as proxies for shading and canopy structure in a Miocene forest from Ethiopia
Abstract Plant fossils are most commonly preserved as isolated organs, making it difficult to determine plant life habit or ecosystem structure from fossils. In particular, paleoecologists haveExpand
