The Baculum in Microtine Rodents

"The Baculum in Microtine Rodents" by Sydney Anderson is a scientific exploration of the baculum, a bone present in the penis of particular mammals, with a focus on its role in classifying and understanding the relationships among different types of microtine rodents, especially within the "Microtus" genus. The publication examines the anatomy of this bone, detailing how specimens were collected and analyzed, and how these observations contribute to understanding differences and evolutionary connections between species, providing a fresh method of identification that can be used with other anatomical features. The writing carefully reviews existing studies on the baculum as it appears in various rodent species, such as "Microtus", "Synaptomys", and "Clethrionomys", including details of how the baculum is preserved and studied, alongside how variations in its structure are observed.
