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 scientific publication produced in the mid-20th century. This thorough biological study focuses on the prairie vole, detailing aspects of its reproduction and development in relation to ecological factors and population dynamics. Written in the context of the University of Kansas Museum of Natural History publications, it sheds light on the species' mating habits, gestation, litter sizes, and other demographic characteristics over a four-year period. The book provides an extensive examination of the prairie vole's reproductive cycle, identifying that the species breeds year-round, with varying rates of reproduction influenced by environmental conditions. Fitch's study includes data on litter sizes averaging around 3.37 young, gestation periods of approximately 21 days, and observations about the social behavior of voles that suggest a non-territorial and somewhat communal lifestyle. Through live-trapping and careful observations, Fitch presents critical insights into the care of young, potential cannibalism among voles, and the impact of environmental factors on population stability and changes over time. The combination of meticulous data collection and detailed observations makes this publication a valuable resource for understanding the ecology and lifecycle of the prairie vole.
