Anderson, Sydney 1927-2018 creator text utu 2010 monographic en 1 online resource : multiple file formats "Subspeciation in the Meadow Mouse, Microtus pennsylvanicus, in Wyoming, Colorado, and Adjacent Areas" by Sydney Anderson is a scientific publication written in the mid-20th century. This book presents an in-depth study on the subspeciation of the meadow mouse in the specific regions of Wyoming and Colorado, focusing on the morphological variations among different subspecies. The work highlights not only the distinctions between subspecies but also the geographical aspects influencing their distribution. The text elaborates on the processes of subspeciation observed within the meadow mouse, delineating specific subspecies based on color, size, and other morphological traits across various localities. Anderson conducts a thorough examination of 762 specimens, comparing skull measurements and physical characteristics to identify and describe three new subspecies, each adapted to their unique environments. The findings underscore the importance of ecological factors in shaping the physical traits of animal populations over a wide geographic area, providing insights into the evolutionary dynamics of these rodents.
