Ecological correlates of single-seededness in a woody tropical flora

Oecologia, 1992
A reduction in seed number per fruit is recognized as a common evolutionary trend among flowering plants. In order to evaluate the ecological role of single-seededness and its possible adaptive significance, we used van Roosmalen's (1985) descriptions of fruits for woody species in the Guianan flora to identify fruit and seed characters and dispersal ...

Woody flora as a predictor of vascular plant richness: An insight in Italy

Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology, 2014
A key problem in quantifying biodiversity is whether it is possible to infer the overall diversity using suitable data subsets. The aim of this article, based on the updated data on the native woody flora of Italy, is to evaluate the reliability of such data as a predictor of vascular plant richness at a medium scale represented by the 20 ...

Severe Drought Effects on Mediterranean Woody Flora in Spain

Forest Science, 2001
Abstract The severe drought in 1994 damaged the woody flora of central and southern Spain (80% of the 190 studied sites presented drought-damaged species). In 1996, after a wet year, 67% of the sites were still affected. Different degrees of damage and recovery were found among different functional types (trees or shrubs), and genera of ...

Ecological Wood Anatomy of the Woody Southern Californian Flora

IAWA Journal, 1985
Wood of 207 species, representing all 178 woody genera of the Munz flora of southern California, was studied by means of sections and macerations. Data were gathered on features relating to the conducting system: number of vessels per mm2, diameter of vessels, length of vessel elements, number of bars per perforation plate, presence of true tracheids ...

Winter leaf loss in the New Zealand woody flora

New Zealand Journal of Botany, 2004
Abstract Approximately 27 species (c. 5%) of the New Zealand woody flora have a marked loss of leaves in winter, although only 10 species are consistently fully deciduous and no extensive vegetation type is dominated by them. There are no summer deciduous species.
