North American Recent Soft-Shelled Turtles (family Trionychidae)

Published in the early 1960s, 'North American Recent Soft-Shelled Turtles' by Robert G. Webb is a scientific examination of the genus 'Trionyx', focusing on various species and subspecies of soft-shelled turtles in North America. The work discusses their taxonomy, natural history, and evolutionary relationships, aimed at biologists and herpetologists. Webb's research is informed by his field observations and addresses the geographical distribution and variations among turtle populations, contributing to the understanding of river ecology and evolution.
