Steve Nix is a member of the Society of American Foresters and a former forest resources analyst for the state of Alabama. Leaf shapes play an important role in tree identification, providing key ...

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 ...

Plant biologists are facing pressure to quantify the response of plants to changing environments and to breed plants that can respond to such changes. One method of monitoring the response of plants ...

Annals of Botany, Vol. 93, No. 2 (February 2004), pp. 149-156 (8 pages) • Background and Aims In some dicotyledonous leaves and leaflets, the secondary veins run more-or-less straight to the margins ...

Life scientists have discovered new laws leaves follow as they grow and evolve. These easy-to-apply mathematical rules can be used to better predict the climates of the past, as determined from the ...

• Leaf vein network geometry can predict levels of resource transport, defence and mechanical support that operate at different spatial scales. However, it is challenging to quantify network ...
