Terrestrial record of recovery The extinction that occurred at the end Cretaceous period is best known as nonavian dinosaurs. In theory, this paved way for expansion mammals well other taxa, including plants. However, there are very few direct records loss and biotic diversity across event. Lyson et al. describe a new from Cretaceous-Paleogene in Colorado includes unusually complete vertebrate plant fossils event detail, mammalian body size increasing animal within first million years....
Abstract Premise Leaf mass per area (LMA) links leaf economic strategies, community assembly, and climate can be reconstructed from woody non‐monocot angiosperm (WNMA) fossils using the petiole metric (PM; width 2 /leaf area). Reliable interpretation of LMA fossil record is limited by an incomplete understanding how PM are correlated at scale what climatic parameters drive variation both measured WNMAs globally. Methods A modern, global, community‐scale data set in situ WNMA was compiled to...
PREMISE The Eocene–Oligocene transition (EOT; 34–33 Ma) was marked by global cooling and increased seasonality aridity, leading to a shift in North American floras from subtropical forests deciduous hardwood similar today. This is well documented taxonomically biogeographically, but its ecological nature less known. METHODS Using the relationship between petiole cross‐sectional area leaf mass, we estimated dry mass per (LMA), functional trait tied plant resource investment expenditure, at 22...
Leaf mass per area (LMA) is a widely used functional trait in both neobotanical and paleobotanical research that provides window into how plants interact with their environment. Paleobotanists have site-level measures of LMA as proxy for climate, biome, deciduousness, community-scale plant strategy, yet many these relationships not been grounded modern data. In this study, we evaluated from the perspective, seeking to add context interpretations discover what combined fossil data set can...
The Chicxulub bolide impact has been linked to a mass extinction of plants at the Cretaceous-Paleogene boundary (KPB; ∼66 Ma), but how this affected plant ecological strategies remains understudied. Previous work in Williston Basin, North Dakota, indicates that pursuing with slow return-on-investment nutrients abruptly vanished after KPB, consistent hypothesis selection against evergreen species during globally cold and dark winter followed impact. To test whether was widespread pattern we...
Climate and environment strongly influence the size, shape, toothiness (physiognomy) of plants' leaves. These relationships, particularly in woody non-monocotyledonous angiosperms, have been used to develop leaf-based proxies for paleoclimate paleoecology that applied reconstruct ancient terrestrial ecosystems last ~120 million years Earth's history. Additionally, given these relationships documented living plants, they are important understanding aspects plant evolution how plants respond...
