Project Gutenberg 2012-06-30 Public domain in the USA. 359 Krutzsch, Philip H. (Philip Henry) 1919 54062615 North American Jumping Mice (Genus Zapus) Produced by Chris Curnow, Joseph Cooper, Tom Cosmas and the Online Distributed Proofreading Team at http://www.pgdp.net "North American Jumping Mice (Genus Zapus)" by Philip H. Krutzsch is a scientific publication written in the mid-20th century. The paper presents a comprehensive study of the genus Zapus, focusing on the taxonomy, geographic distribution, and evolutionary history of North American jumping mice. It aims to record the known variations and relationships among the species and subspecies within this genus, providing essential insights into their ecological and evolutionary significance. The opening of the work introduces the genus Zapus, noting the distribution of jumping mice across northern North America, from the Arctic Circle to regions as far south as central California. The author emphasizes the general lack of comprehensive taxonomic attention for these rodents since a prior revision in the late 19th century, despite the identification of new subspecies. Additionally, the section outlines the research methods and acknowledgment of collaboration with various institutions, underscoring the extensive study based on thousands of specimens collected from multiple geographic locations. This establishes a strong foundation for the detailed analysis that follows, delving into the paleontological aspects, species characteristics, and systematic accounts of the identified species.
