Bryophytes and Lichens,cies of mosses and liverworts can recover after many years of nearly complete dehydration, a characteristic that enables them to form an important, though scientifically neglected, part of the vegetation of arid and semiarid environments.

Montane and Wadi vegetation,rogeology of the region. From the Tertiary onwards the mountains were important phytogeographically, providing a relatively equable climatic ‘corridor’ between Africa and Asia, and ., during the Late Tertiary (see Chapter 4), and today the higher altitudes provide a climatic refuge for species that once had much wider distributions.

Biogeography and Introduction to Vegetation,graphical structures and the effects of man and his livestock have all played a part in the establishment and development of the flora and vegetation of Arabia. The varied and often dramatic terrain of the 2.7 million km. of the Peninsula (Figures 3.1–3.4) is subject to a climate that ranges from th

Bryophytes and Lichens,n an early evolutionary ‘branch’ from ancestral chlorophytes (green algae). These ‘primitive’ plants have no highly differentiated tissues for water conduction or mineral transport, and they absorb nutrients, water and carbon dioxide directly through their cell walls. They can survive under very var

Montane and Wadi vegetation,more remote regions have yet to yield their final secrets. These mountain chains, lying on the western, southwestern and eastern periphery of the Peninsula, were uplifted during the period of the great Alpine orogeny from the Mid Tertiary onwards, and they were thereafter eroded, often dramatically,
