AbstractQuestion: Do thick‐twigged/large‐leaf species have an advantage in leaf display over their counterparts, and what are the effects of leaf habit and leaf form on the leaf‐stem relationship in plant twigs of temperature broadleaf woody species?Location: Gongga Mountain, southwest China.Methods: (1) We investigated stem cross‐sectional area and

Foliar Habit and Leaf Longevity
2011The origins of the study of leaf longevity lie in the distinction between evergreen and deciduous plant species, which is not as simple as it first seems. The evergreen habit basically is defined by the retention of functional leaves in the plant canopy throughout the year, as opposed to the deciduous habit in which a plant is leafless for some part of

Adaptive role of leaf habit in extinct polar forests
International Forestry Review, 2004Fossils provide clear evidence of forests covering the Arctic and Antarctic throughout most of the past 250 million years. Ancient polar forests experienced the extreme seasonality of high latitude daylength, but flourished in a warm, temperate climate. For the past 50 years, it has been argued that deciduous trees in these ecosystems conserved carbon

The Leaf-Mining Habit in the Hymenoptera
Annals of the Entomological Society of America, 1925Our knowledge of the leaf-mining habit in the Hymenoptera dates back to De Geer (1752). Although Reaumur (1737) and Swammerdam (1758) speak of the leaf-mining habit, they make no mention of the Hymenoptera. Since the time of De Geer, several comprehensive papers have appeared, dealing wholly or in part with the leaf-mining Hymenoptera.

Biogeography of Leaf Longevity and Foliar Habit
2011There is, apparently, no general restriction on variation in leaf longevity per se along local and regional spatial gradients. Leaf longevity is only part of a suite of foliar traits that act in concert to ensure effective photosynthetic function in a given environmental regime (Wright et al. 2004; Shipley et al. 2006).

The Evolution and Adaptive Significance of the Leaf-Mining Habit
Oikos, 1997Feeding inside leaves by leaf-mining insects has been viewed as an adaptive innovation for consuming foliage. The leaf mine presumably provides its occupant shelter from the detrimental effects of the physical environment, protection from attack by natural enemies, and potentially a means of avoiding plant defenses concentrated in particular layers of ...

Leaf lifespans of five dominant shrub species, belonging to the Asteraceae (Compositae), were determined at a high elevation paramo site (4060 m a.s.l.) in Ecuador. Although climatic conditions in this cold, aseasonal environment appear to be quite constant year-round, leaf half-lifes of shrubs varied by nearly an order of magnitude (2.7 to 21.7 months)

Functional relationships of leafing intensity to plant height, growth form and leaf habit
Acta Oecologica, 2012Leafing intensity, i.e. the number of leaves per unit of stem volume or mass, is a common developmental correlate of leaf size. However, the ecological significance and the functional implications of variation in leafing intensity, other than its relation to leaf size, are unknown. Here, we explore its relationships with plant height, growth form, leaf

It is well known that evergreen and deciduous species have different functional traits and utilize different strategies in growth and adaptation to environments, however little work has been done to elucidate whether leaf habit mediate the effect of trait-environment interactions on plant performance.

Plant Ecology, 2020
Spring leaf phenology has been intensively studied in temperate deciduous broad-leaved tree species, but the phenology of evergreen broad-leaved tree species has seldom been focused on. Evaluation of the difference in spring leaf phenology between coexisting deciduous and evergreen species is essential to predict their responses to climate change.
