Arid and Semi-Arid Zones of Mexico: A Comprehensive Exploration of Biodiversity, Ecology, and Conservation is an in-depth, multidisciplinary examination of one of Mexico's most ecologically distinctive and biologically rich landscapes. Comprising 14 chapters authored by subject-matter experts, this reference work investigates the climatic, physical, and biological characteristics of Mexico's principal arid and semi-arid regions. The volume presents detailed assessments of emblematic plant and animal species, while also exploring the ecological roles of nursery processes and the consequences of human activity on fragile desert ecosystems. Conservation priorities are addressed through evaluations of protected natural areas and the safeguarding of native germplasm resources. Additionally, the contributors document the medicinal and biologically active products derived from arid-zone flora, highlighting their ecological and cultural significance. Each chapter integrates case studies and findings from Mexico's key arid regions — the Baja California Peninsula, Chihuahuan Desert, Sonoran Desert, and Tehuacán-Cuicatlán Valley.
