As shown, the marcescent oak woodlands in Southern Portugal are intimately connected with mountainous areas, or specific edaphic typologies which understanding has led to several advances, including taxonomic aspects of this theme.
xneomairei) referring to hybridisation in marcescent oaks.
Ungulates strongly selected against branches with marcescent leaves of beech and hornbeam, but showed no preference in common oak (ANOVA: leaves: [F.
The most noticeable difference in fiber was higher levels of lignin in the marcescent leaves of beech and hornbeam compared with stems.
The feeding trial I conducted clearly demonstrated that ungulates avoided branches of beech and hornbeam with marcescent leaves, but not branches of common oak (Fig.
Marcescent leaves of beech and hornbeam likely reduced overall digestibility (Table 1) of available forage for ungulate herbivores because of their high lignin and low protein content (Van Soest 1994).
When marcescent leaves constitute most of the diet, ungulates spend more time processing food, especially increased rumination time because of lower food quality (Robbins 1993).
As a consequence, they would not require large amounts of low-quality browse, which may explain why common oak with marcescent leaves was not avoided.
In addition, Salix pulchra in arctic environments of Alaska and eastern Siberia has marcescent leaves (Hulten 1968).
