"A New Bog Lemming (Genus Synaptomys) From Nebraska" by J. Knox Jones is a scientific publication written in the mid-20th century. This work focuses on the discovery and classification of a new subspecies of bog lemming in Nebraska. It presents detailed morphological descriptions and comparisons against other subspecies, contributing to the understanding of biodiversity in North America. The document introduces the newly identified subspecies, named "Synaptomys cooperi relictus", obtained from Rock Creek State Fish Hatchery in Dundy County, Nebraska. Jones discusses the unique characteristics of this population, noting differences in size, coloration, and skull features compared to related subspecies like "S. c. gossii" and "S. c. paludis". The publication emphasizes the small size of the population and its potential to be a remnant of more widespread distributions during earlier geological periods, shedding light on the ecological history of the region. Overall, this work highlights the significance of field studies and specimen collection in enhancing scientific knowledge of lesser-known wildlife species.
