Oscar Francke has written a chapter about the scorpion distribution in the Cuatro Ciénegas Basin in Mexico in the recently published book "Animal Diversity and Biogeography of the Cuatro Ciénegas Basin".
Twelve species of scorpions, belonging to three families and seven genera, have been recorded from the Cuatro Cienegas Basin (CCB). Two are considered endemic, but this might be due to poor sampling efforts in other areas of the state of Coahuila; the other ten species are widely distributed in the Chihuahuan Desert and are not threatened at the time. However, there is concern about the populations inside the Basin because the increasing aridification is causing a loss in primary productivity, which in turn has an impact on the arthropods that scorpions feed upon.
