There is a strong natural light gradient from the top to the bottom in plant canopies and along
gap-understorey continua. Leaf structure and photosynthetic capacities change close to …

The purpose of this review is to discuss sources of variation in osmotic potentials (ψπ), with
special reference to North American tree species. Lowering of osmotic potentials by solute …

Our knowledge of the ecology of tropical rain-forest trees is limited, with detailed information
available for perhaps only a few hundred of the many thousand of species that occur. Yet a …

Why do Australian rainforests occur as islands within the vast tracts of Eucalyptus? Why is
fire a critical ecological factor in every Australian landscape? What were the consequences …

Many excellent reviews have been written about plant water status and its measurement (eg
Slaty er, 1967; Barrs, 1968; Boyer, 1969; Brown and van Haveren, 1972; Slavik, 1974; …

Abstract Knowledge of variations in morphophysiological leaf traits with forest height is
essential for quantifying carbon and water fluxes from forest ecosystems. Here, we …

Leaf structure in 17 temperate, broad—leaved tree species on xeric, mesic, and wet—mesic
sites in central Pennsylvania (USA) was compared to leaf gas exchange and tissue—water …

Variations in the partitioning of foliar carbon and nitrogen in combination with changes in
needle and shoot structure were studied in trees of Picea abies along a vertical gradient of …

Vertical profiles in leaf mass per unit leaf area (MA), foliar 13 C composition (δ 13 C),
nitrogen (N), phosphorus (P), carbon (C) and major cation concentrations were estimated for …

Foliar morphology and chemical composition were examined along a light gradient in the
canopies of five deciduous temperate woody species, ranked according to shade-tolerance …
