Environmental and specific diversity in the Chihuahuan desert in
general, and in the Cuatro Cienegas Basin in particular, has long
been recognized as outstanding. This book provides a global
ecological overview, together with in-depth studies of specific
processes. The Chihuahuan desert is the warmest in North America,
and has a complex geologic, climatic and biogeographical history,
which affects today's distribution of vegetation and plants and
generates complex phylogeographic patterns. The high number of
endemic species reflects this complex set of traits. The modern
distribution of environments, including aquatic and subaquatic
systems, riparian environments, gypsum dunes and gypsum-rich soils,
low levels of phosphorous and organic matter, and high salinity
combined with an extreme climate call for a range of adaptations.
Plants are distributed in a patchy pattern based on punctual
variations, and many of them respond to different resources and
conditions with considerable morphological plasticity. In terms of
physiological, morphological and ecological variability, cacti were
identified as the most important group in specific environments
like bajadas, characterized by high diversity values, while
gypsophytes and gypsovagues of different phylogenies, including
species with restricted distribution and endemics.

This book takes readers on a journey through the history of water
in the Coahuila desert. It starts by describing the beauty and
mysteries of the landscape, and then explores the rock art of the
original desert cultures in Coahuila, offering readers a glimpse of
the sacred nature of water in the desert, as well as the rituals
surrounding it. Moving on to the colonial times and the post-
independence development of the region, it discusses early water
management, and explores how water is managed in modern times, as
well as the legal complications of the law, and how these faulty
laws, designed for less arid regions, have affected a highly
diverse wetland, the Cuatro Cienegas oasis. The book then examines
the biological consequences of the water loss for the aquatic
plants and animals in Churince - a now extinct system within Cuatro
Cienegas. Further, it addresses how even bacteria can become
extinct in this hyper-diverse microbial oasis. Lastly, after this
despair and sense of loss, the book provides hope, offering
suggestions for how we can transform the future, from a social and
educational point of view as well as through good science and
changes in policy.
