Species knowledge is essential for protecting biodiversity. The identification of plants by
conventional keys is complex, time consuming, and due to the use of specific botanical …

The design and function of leaf venation are important to plant performance, with key
implications for the distribution and productivity of ecosystems, and applications in …

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

Plant identification systems developed by computer vision researchers have helped
botanists to recognize and identify unknown plant species more rapidly. Hitherto, numerous …

Plants are of fundamental importance to life on Earth. The shapes of leaves, petals and
whole plants are of great significance to plant science, as they can help to distinguish …

Across plant species, leaves vary enormously in their size and their venation architecture, of
which one major function is to replace water lost to transpiration. The leaf hydraulic …

Although they are relative latecomers on the evolutionary scene, having emerged only 135?
170 million years ago, angiosperms—or flowering plants—are the most diverse and species …

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 …

We report a time-calibrated stratigraphic section in Colorado that contains unusually
complete fossils of mammals, reptiles, and plants and elucidates the drivers and tempo of …

Abstract Background and Aims Leaf size has considerable ecological relevance, making it
desirable to obtain leaf size estimations for as many species worldwide as possible. Current …
