The Bolivian chinchilla rat (Abrocoma boliviensis) is one of the most threatened mammal species in the world. This photo, is the result of several years of field work, showing an individual, possibly a female, being preyed upon by a Geoffroy cat.  A. boliviensis was described by William Glanz and Sydney Anderson in 1990. However, so far, scientific information on the species is virtually non-existent.  In this issue of THERYA, with articles dedicated to the memory of Dr. Sydney Anderson, a work dedicated to the ecology of A. boliviensis is presented showing that populations of the species still exist, apparently more or less healthy, in the center from Bolivia (photo: Carmen Julia Quiroga).
