Plasticity to daylength of Iris pumila leaf phenological traits
Population Ecology, 2003AbstractPlastic responses to photoperiod of Iris pumila leaf phenological traits were investigated in two populations experiencing contrasting light conditions in the dune system at Deliblato Sands (44°48′ N, 38°58′ E; Serbia, Yugoslavia). The population “Dune” occupied an exposed area at the top and slope of a relatively large dune, and the population

Leaf Phenology of Trees in the Pasoh Forest Reserve
2003We studied the phenology of leaf emergence in 94 trees and the leaf dynamics of 17 selected trees in the Pasoh Forest Reserve (Pasoh FR), Malaysia. We tested the following hypotheses: (i) the phenology of leaf emergence differs among trees of different heights because of differences in the relative importance of meteorological factors, and (ii) the ...

Leaf phenology in relation to canopy closure in southern Appalachian trees
American Journal of Botany, 2008Leaf phenology varies markedly across tree species of temperate deciduous forests. Early leafing in spring may increase light capture and carbon gain prior to canopy closure, allowing saplings to survive in understory sites deeply shaded in midsummer.

Leaf Phenology and Leaf Damage of Saplings in the Luquillo Experimental Forest, Puerto Rico1
Biotropica, 2000ABSTRACTChanges in light or water availability can result in synchronous leaf production, concentrating food availability for herbivores of young leaves to only a few months. To determine the importance of food availability on herbivory, leaf phenology and leaf damage were studied in the Luquillo Experimental Forest (LEF) of Puerto Rico.

Leaf Life-Span and Leafing Phenology of Lianes and Associated Trees During a Rainforest Succession
The Journal of Ecology, 1990In a predominantly evergreen Queensland subtropical rainforest leafing phenology was very similar in lianes and trees, with maximum activity in spring. Mean number of leaves in the standing crop of leaves present per species increased by 27% in trees (10 species) and 70% in lianes (10 species) between autumn and early summer, before returning to within

Journal of Vegetation Science, 1995
Abstract. In this study, we documented patterns of variation in leaf phenology and leaf herbivory in scrub oak (Quercus ilicifolia Wang) along the slope of a closed topographical depression, 15 m deep and 400 m wide, in the pine barrens of eastern Massachusetts.

Phenological indicators of resources offered to leaf herbivores in restinga communities
American Journal of BotanyAbstractPremisePlants can limit the leaf tissue consumed by insect herbivores through chemical, structural, and nutritional leaf defenses or by escaping in space and time. Escaping is related to the phenological patterns of plants, which in turn respond to climatic factors.

Extended leaf phenology and the autumn niche in deciduous forest invasions
Nature, 2012The phenology of growth in temperate deciduous forests, including the timing of leaf emergence and senescence, has strong control over ecosystem properties such as productivity and nutrient cycling, and has an important role in the carbon economy of understory plants. Extended leaf phenology, whereby understory species assimilate carbon in early spring

Leaf Mottling: Relation to Growth Form and Leaf Phenology and Possible Role as Camouflage
Functional Ecology, 1990The arguments of Smith (1986) bearing on the adaptive significance of leaf mottling are criticized and an alternative hypothesis is presented. I propose that mottling may serve to camouflage the foliage of certain groups of shortstatured forest herbs, by disrupting their outline as perceived by colour-blind vertebrate herbivores in sun-dappled ...
