To maximize net gain of a tree, leaves must be replaced when net gain of a leaf per unit time over the leaf's life span is maximum. A model in which leaf longevity is determined to maximize the net gain of a leaf per unit time is constructed. The model predicts that leaf longevity is short when initial net photosynthetic rate of the leaf is large, long when the construction cost of the leaf is large, and short when the decrease in net photosynthetic rate with time is large. The model describes… Expand
The basis for variation in leaf longevity of plants
Any theory of leaf phenology must predict leaf longevity, leaf habit, leaf expansion and its timing among other variables. These phenological traits may be important keys to understand the responseExpand
The basis for variation in leaf longevity of plants.
TLDR
Theories of leaf longevity were re-evaluated and leaf longevity is concluded to be optimized to maximize plant carbon gain. Expand
Significance of leaf longevity in plants
TLDR
The results suggest that the construction and maintenance costs of supporting structures significantly influence life span of individual leaves, which connects the ecophysiology of the individual leaf to growth of the Individual plant and energy and matter cycling at the ecosystem level. Expand
Geographical distribution of leaf life span and species diversity of trees simulated by a leaf-longevity model
The leaf life span, leaf habit (evergreenness and deciduousness), and species diversity of trees were simulated by a cost-benefit model of leaf longevity (Kikuzawa 1991), using monthly meanExpand
Leaf Photosynthesis Integrated over Time
TLDR
A series of papers based on Kikuzawa's (1991) cost-benefit model for leaf longevity are reviewed, including its extension to whole plants and entire communities in seasonal environments, suggesting the possibility that the lifetime carbon gain by a single leaf can be extended by analogy to predict the productivity of forest ecosystems.

Decline of photosynthetic capacity with leaf age and position in two tropical pioneer tree species.
The effect of leaf age on photosynthetic capacity, a critical parameter in the theory of optimal leaf longevity, was studied for two tropical pioneer tree species, Cecropia longipes and UreraExpand
Leaf phenology as an optimal strategy for carbon gain in plants
TLDR
Leaf longevity is shown to maximize carbon gain through three parameters: leaf photosynthetic rate, the decrease in photosynthesis rate with leaf age, and the initial construction costs of the leaf. Expand
Photosynthetic capacity, integrated over the lifetime of a leaf, is predicted to be independent of leaf longevity in some tree species.
TLDR
It may be predicted that CO2 assimilation integrated over the lifetime of the leaf should be independent of leaf longevity. Expand
Toward Synthesis of Relationships among Leaf Longevity, Instantaneous Photosynthetic Rate, Lifetime Leaf Carbon Gain, and the Gross Primary Production of Forests
TLDR
The gross production of forest ecosystems then can be predicted to a first approximation simply by the annual duration of the period favorable for photosynthetic activity in any given region. Expand
Leaf lifespan and lifetime carbon balance of individual leaves in a stand of an annual herb, Xanthium canadense.
TLDR
The results suggest that the mechanism by which leaf lifespan is determined changes depending on the availability of the resource that is most limiting to plant growth. Expand

Relationships Among Leaf Construction Cost, Leaf Longevity, and Light Environment in Rain-Forest Plants of the Genus Piper
TLDR
It is concluded that the more general hypothesis, predicting a positive relationship between longevity and the ratio of cost to carbon gain, is conceptually more robust and consistent with the data presented. Expand

TLDR
Differences in leaf dynamics of early and late species are related to the successional niches they occupy in the forest community. Expand
Leaf Structure and Photosynthetic Performance as Related to the Forest Succession of Deciduous Broad‐Leaved Trees1
TLDR
Photosynthetic response to light intensity and leaf anatomy was measured in trees of 30 seral deciduous broad-leaved species native to the northern part of Japan and there was a positive correlation between cuticle ratio and leaf longevity and a negative correlation between the leaf stable period and saturated photosynthetic rates.

The Ecology of Leaf Life Spans
TLDR
This review considers the question "How is the length of a leaf's life span related to environmental factors?" and what are the comparative advantages of the evergreen and deciduous habits and how can adaptive differences be related to distributional patterns and climatic gradients. Expand
Photosynthetic rates in relation to nitrogen recycling as an adaptation to nutrient deficiency in peat bog plants
TLDR
The hypothesis is advanced that the increased time available to use nitrogen photosynthetically before it is recycled is adaptive in bog plants, especially in evergreens, because of the difficulty in acquiring nitrogen from the extremely nutrient-deficient bog substrate. Expand
