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.

Global Ecology and Biogeography, 1998
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)

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.

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

Leaf Gas Exchange Activity in Soybean as Related to Leaf Traits and Stem Growth Habit
Crop Science, 2008Understanding the relationships between leaf photosynthetic activity and physiological and morphological traits of soybeans [Glycine max. (L.) Merr.] with different stem growth habits could be exploited for yield improvement. Leaf photosynthetic rate (Pn), stomatal conductance (gs), leaf mass per unit area (LMA), and leaf nitrogen content per unit area

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 economic traits from fossils support a weedy habit for early angiosperms
American Journal of Botany, 2010Many key aspects of early angiosperms are poorly known, including their ecophysiology and associated habitats. Evidence for fast‐growing, weedy angiosperms comes from the Early Cretaceous Potomac Group, where angiosperm fossils, some of them putative herbs, are found in riparian depositional settings.

A possible link between hydraulic properties and leaf habits in Hevea brasiliensis
Functional Plant Biology, 2015A link exists between hydraulic traits and leaf habit. However, few attempts have addressed a possible link between hydraulic traits and altered leaf habit in introduced ranges. Within its native range, the Amazon rainforest, Hevea brasiliensis (Willd. ex A. Juss) Muell. Arg. is an evergreen but it becomes drought-deciduous in non-native ranges.

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.
