Taxonomic Status of Some Mice of The Peromyscus boylii Group in Eastern Mexico, With Description of a New Subspecies

"Taxonomic Status of Some Mice of The Peromyscus boylii Group in Eastern Mexico, With Description of a New Subspecies" by Ticul Alvarez is a scientific study from the early 1960s that untangles the classification of mice belonging to the Peromyscus boylii group in Eastern Mexico. The study scrutinizes differences in the family of mice, subspecies, and where they are found, offering a revised look at how they're categorized. Alvarez checks past classifications and shines a light on the unique traits that separate species like Peromyscus aztecus and Peromyscus boylii levipes. By looking at mice taken from Veracruz, Puebla, and Nuevo León areas, Alvarez provides detailed insight, about the newly found, small-sized Peromyscus b. ambiguus. This study aims to clarify the exact taxonomic position of these mice and their unique make-up, highlighting how they contribute to the diverse environment of Mexico.
