Leaf mines: their effect on leaf longevity

Oecologia, 1984
The effects of a number of factors, notably leaf mining insects, on the longevity of beech and holm oak leaves have been studied. The regular monitoring of individually labelled leaves was complemented by analysis of leaf fall data. Both methods confirm that these mining insects have only a slight impact on their host trees.

Leaf‐Critical and Leaf‐Stable Graphs

Journal of Graph Theory, 2016
AbstractThe minimum leaf number ml(G) of a connected graph G is defined as the minimum number of leaves of the spanning trees of G if G is not hamiltonian and 1 if G is hamiltonian. We study nonhamiltonian graphs with the property for each or for each . These graphs will be called ‐leaf‐critical and l‐leaf‐stable, respectively.

Leaf Senescence

Annual Review of Plant Biology, 2007
Leaf senescence constitutes the final stage of leaf development and is critical for plants’ fitness as nutrient relocation from leaves to reproducing seeds is achieved through this process. Leaf senescence involves a coordinated action at the cellular, tissue, organ, and organism levels under the control of a highly regulated genetic program.
