Migrations, Population Size Structure, and Reproduction of the Dwarf Salamander,
Eurycea quadridigitata, in South Carolina
D. Semlitsch and Michael A. McMillan
Life history parameters of
Eurycea quadridigitata from two populations on the upper Coastal
Plain of South Carolina were examined. Breeding
migrations into Carolina bays occurred during September and October in 1978 and
July through October in 1979. The initiation of breeding migrations was associated with a
drop in air temperature during late summer or early autumn.
The sex ratio of E. quadridigitata entering the breeding
sites was 1:1. Egg deposition
probably occurs during November and early December.
Sexual dimorphism in snout-vent length (SVL) was not present, but there
was significant local variation in SVL of adults (x=26 and 29 mm).
The number of ovarian eggs was positively correlated with SVL and varied
between populations (x=21 and 33).
