The stepwise rise of angiosperm‐dominated terrestrial ecosystems

Biological Reviews, Volume 100, Issue 5, Page 2131-2149, October 2025.
ABSTRACT Angiosperms are the most diverse and abundant plant taxon today and dominate the majority of Earth's terrestrial ecosystems. They underwent rapid divergence and biogeographic expansion from the early to the middle Cretaceous. Yet, transformative ecosystem change brought about by the increased ecological dominance of angiosperms unfolded ...

Capturing Vegetation Gradients Along the West African Margin Using Terrestrial Plant Biomarkers in Marine Sediments

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 7, July 2025.
Abstract Understanding the transport mechanisms of terrestrial biomarkers to marine sediments is critical for interpreting past environmental and climate changes from these valuable archives. Here, we produce new estimates of two classes of terrestrial plant biomarkers, n‐alkane waxes and pentacyclic triterpene methyl ethers (PTMEs), from a transect of

Historic rewiring of grass flowering time pathways and implications for crop improvement under climate change

New Phytologist, Volume 245, Issue 5, Page 1864-1878, March 2025.
Summary Grasses are fundamental to human survival, providing a large percentage of our calories, fuel, and fodder for livestock, and an enormous global carbon sink. A particularly important part of the grass plant is the grain‐producing inflorescence that develops in response to both internal and external signals that converge at the shoot tip to ...
