Ecology of the Opossum on a Natural Area in Northeastern Kansas

This 1954 monograph offers a meticulous portrait of the opossum's life in mid-century Kansas, drawn from three years of intensive fieldwork (1949-1952) on the University of Kansas Natural History Reservation. Henry S. Fitch and his colleagues employed live-trapping to track these nocturnal marsupials across changing landscapes where larger predators had vanished, capturing a pivotal moment in American ecology when scientists were first documenting how ecosystems reshaped themselves. The research reveals opossums as surprisingly adaptable creatures: home-ranging across roughly 50 acres, surviving on varied diets of wild fruits and crustaceans, navigating breeding cycles marked by high population turnover and steep odds for juveniles. The prose is that of careful science, but the subject matter possesses its own quiet drama: a common animal rarely studied with such patience, rendered in data and observation that still inform wildlife biology today. For ecologists, naturalists, and anyone curious about the roots of American field research, this document offers both historical insight and genuine scientific value.
