Leaf nutrient resorption, leaf lifespan and the retention of nutrients in seagrass systems [PDF]

open access: yesAquatic Botany, 1999
Efficient nutrient resorption from senescing leaves, and extended leaf life spans are important strategies in order to conserve nutrients for plants in general.

Effects of leaf emergence on leaf lifespan are independent of life form and successional status

open access: yesAustral Ecology, 2008
The longevity of a leaf is related to the benefit that the plant is able to derive from it.This benefit varies among seasons and as more leaves emerge, such that leaf lifespan can be limited by canopy position rather than physiological age.

Tissue‐level leaf toughness, but not lamina thickness, predicts sapling leaf lifespan and shade tolerance of tropical tree species

open access: yesNew Phytologist, 2010
Leaf toughness is thought to enhance physical defense and leaf lifespan. Here, we evaluated the relative importance of tissue-level leaf traits vs lamina thickness, as well as their ontogenetic changes, for structure-level leaf toughness and regeneration

A process-based model of conifer forest structure and function with special emphasis on leaf lifespan [PDF]

open access: yesGlobal Biogeochemical Cycles, 2002
We describe the University of Sheffield Conifer Model (USCM), a process-based approach for simulating conifer forest carbon, nitrogen, and water fluxes by up-scaling widely applicable relationships between leaf lifespan and function. The USCM is designed
