Investigations of the Illinois Chorus Frog: 'Pseudacris streckeri illinoensis.' Long Term Resource Monitoring Program

摘要

A description of naturally-occurring newly transformed froglets of the Illinois chorus frog, Pseudacris streckeri illinoesis, is presented. Coloration of all froglets is a uniform reddish brown in color with a much darker shaded tail stub. Uniform coloration is cryptic when associated with the wet sand on which the frogs emerge. Mean snout-vent length for 208 specimens averages 19 mm with a mean tail stub length of 10 mm. Mean snout-vent length for frogs that reabsorbed the tail stub was 21 mm for 506 specimens. Snout-vent length of froglets in this population is large compared to congeners.
