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 scaling relationships of ...

Research by Assistant Professor Jacob S. Suissa at the University of Tennessee, Knoxville, is revealing complexity in how ferns have evolved. Instead of the vascular structure inside fern stems ...

A comprehensive analysis of global patterns in leaf size offers an answer to one of the longest-standing questions in plant ecology - why plant leaf size increases at lower latitudes -- scientists now ...

Scientists have determined how key developmental genes influence growth of cells to produce such differences in leaf form. The researchers were able to make thale cress, which typically produces ...

For centuries, artists, biologists and mathematicians have been inspired by the recurring patterns of the plant world: the exquisite symmetry of flowers, the sweeping spirals of seeds, spines and ...

Salt farmers have taken a leaf out of nature's book to create these incredible shapes on a dry lake. The patterns in the lake bed are an astonishing 100 metres long and look just like leaves - and ...
