500 |a"Threatened, 2015."
500 |a"COSEWIC would like to acknowledge Ray Poulin ... [et al.] for writing the draft of the status reportwould like to acknowledge Ray Poulin, Chris Somers, Laura Gardiner, and Jessica Martino for writing the draft of the status report [...]. This report was overseen, edited, revised, and updated by Jim Bogart and Kristiina Ovaska, Co-chairs of the COSEWIC Amphibians and Reptiles Specialist Subcommittee"--Cf. (p. ii).
504 |aIncludes bibliographical references (p. 43-52).
520 |a"Since the previous status report (COSEWIC 2004), new survey information has helped refine distributions of both the Eastern and Western Yellow-bellied Racers, and several previously unknown den sites have been documented. New molecular work completed on 150 Eastern Yellow-bellied Racers from two river valleys (Frenchman and the Big Muddy river valleys) indicates that there may be several genetically distinct subpopulations in Canada. A major terrain slump event occurred in the spring of 2011 at the largest known den site of the Eastern Yellow-bellied Racer and displaced or killed a potentially significant but unknown proportion of racers at the den. No new information exists on population size and trends of Western Yellow-bellied Racers, but threats have been assessed and remain substantial”--Preface, p. xvi.
