It is difficult for me to recollect a time when I was not fascinated with the very notion of a desert. Walt Disney's film, The Living Desert, which I initially saw when I was 8 years of age, provided me with my first glimpse of this wondrous yet seemingly ho stile environment. The images were hypnotic and captivating. I looked on in amazement at the promenade Cl deux of the male and female scorpions during courtship. Their rhythmic and coordinated movements as they grasped one another made them appear to glide in unis on over the surface of the sand, each individual totally absorbed with its partner. In the next minute the fern ale had suddenly and utterly transformed herself like some Jekyll and Hyde act, into an aggressive predator whose prior gregarious embrace was now a hold of death for the male. The indomitable desert grasshopper mouse, the ever sentient kit fox, the graceful shovel-nosed snake swimming in an endless sea of sand.

Annual desert plant species of unrelated taxa in the Negev Desert of Israel have developed complementary sets of adaptations and survival strategies as ecological equivalents with physiological, morphological and anatomical resemblances, in the various stages of their life cycles. After 40 years of research in hot deserts Yitzchak Gutterman provides a comprehensive treatise of such adaptations and strategies. In doing so he covers the following topics: post-maturation primary seed dormancy, which prevents germination of maturing seeds before the summer; seed dispersal mechanisms with escape or protection strategies; cautious or opportunistic germination strategies; seedling drought tolerance. The day-length is an important factor in regulating flowering as well as the phenotypic plasticity of seed germination which is also affected by maternal factors.

There are two basic strategies for coping with life in the desert. The first involves withstanding the extreme conditions using behavioural or physiological tactics. The second strategy is to be a migrant and to opportunistically or seasonally move to where the necessary resources are. Nomadism, i.e. the opportunistic and irregular movements from resource-poor to resource-rich patches, is a tactic that birds, with their mobility, can use, and it is explored by W.R.J. Dean in this volume. For many bird species, such movements between habitats or across landscapes to find patches of resources are essential for their continued existence. The relationship between climate, habitat and movements in the avifauna of arid and semi-arid regions and the advantages and disadvantages of a seasonally migratory or opportunistically nomadic lifestyle are elucidated.
