Beschreibung:
<jats:p>The climatic similarity of desert environments everywhere has engendered parallelism and the evolution of ecological analogues in different regions of the world. This tends to mask the actual diversity of their inhabitants. Although biodiversity may be poor in the desert, at least compared with most other terrestrial ecobiomes, deserts are extremely vulnerable to degradation and therefore deserve as much as, or even more, consideration than many biologically richer habitats.</jats:p>
