Aspects of Reproduction and Development in the Prairie Vole (Microtus ochrogaster)

"Aspects of Reproduction and Development in the Prairie Vole (Microtus ochrogaster)" by Henry S. Fitch is a scientifically detailed record from the mid-20th century that uncovers the secret lives of prairie voles. The study, born from research at the University of Kansas Museum of Natural History, follows the reproductive and developmental aspects of this small mammal, revealing how ecological factors play a role in their population. It is a carefully constructed account of their habits, including mating rituals, the length of pregnancy, and litter sizes, documented over four years. The book exposes findings, such as year-round breeding cycles and the impact of the environment on making baby voles. Figures of about 3.37 young per litter, a 21-day pregnancy, plus observations on communal living and hints of possible cannibalism among voles, are supported by live-trapping evidence. The study highlights how environmental worries affect the ups and downs of vole numbers, making the publication a key source for understanding the prairie vole's life.
