Severe Drought Effects on Mediterranean Woody Flora in Spain
Forest Science, 2001Abstract 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, 1985Wood 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 ...

Summary Resting bud cataphylls are often assumed to play an essential protective role in winter due to their widespread presence among temperate, woody plants. This view is challenged by our documentation of significant numbers of temperate woody angiosperm taxa with naked buds that overwinter without cataphyll protection.

Chinese Geographical Science, 1998
There are 463 species of woody plant, belonging to 166 genera and 70 families in Shanxi, North China. The floristic composition types of genera and species are abundant, in which the compositions distributed in temperate zones (including North Temperate, Old World Temperate and Temperate Asia), having 62 genera, are dominant and account for 38.27% in ...

Chorology of the Euxinian and Hyrcanian element in the woody flora of Asia
Plant Systematics and Evolution, 1989The Euxinian and the Hyrcanian floristic province are analysed in respect to their trees and shrubs. These provinces mark the southern limit of the Euro-Siberian Region in SW. Asia. Mesophyllic forests dominate; they are deciduous, but there is a substantial component of evergreen shrubs in the understorey.

Patterns of endemism in the woody flora of north-east and east Africa
1996Tree and shrub species of restricted distribution do not occur randomly throughout the vegetation types and geomorphological formations of eastern Africa, but rather, show distinct concentrations of high endemism. Four geographical areas of high endemism are considered, the Eastern Arc mountain forests, the Eastern Arc rain shadow, the dry transitional

Effect of forest fragmentation on the woody flora of the highlands of Chiapas, Mexico
Biodiversity & Conservation, 2004This study was conducted in the Chiapas Highlands, a tropical mountain region where traditional agricultural practices have resulted in a mosaic landscape of forest fragments embedded in a matrix of secondary vegetation and crop fields. The question addressed was how may woody species richness be affected by forest fragment attributes derived from ...

Threatened woody flora as an ecological indicator of large herbivore introductions
Biodiversity and Conservation, 2017Rewilding and translocations of large herbivores for conservation purposes have increased in recent times, with numerous introductions inside and outside their native range. This study aims to analyze the use of threatened plant taxa as a possible ecological indicator of large herbivore introductions.

Altitudinal distribution patterns of the native and alien woody flora in Kashmir Himalaya, India
Environmental Research, 2011(Uploaded by Plazi for the IPBES Invasive Alien Species Assessment) Background: Many studies have shown that alien species richness pattern follows that of native species richness patterns along environmental gradients, without taking the specific composition of the two groups into account. Objectives: To compare species richness patterns of native and
