 SNOUT-UROSTYLE LENGTH (mm)


Figure 7. Size-class structure of multi-year recaptured Gastrophryne carolinensis at Breezeway Pond,
Putnam Co., Florida, 1986 1990. Recaptures occurred after 1 year (N = 88), 2 years (N = 12), 3 years (N
= 11), or 4 years (N = 2).


years were quite similar to one another and included only larger adults. Only two
toads were captured four years after marking.
 For the three years with the most multi-year recaptures, recaptured males
were larger than unmarked males in 1987 (mean=26.6 mm, N=13) but smaller
than unmarked males in 1988 (mean=27.3 mm, N=27) and 1989 (mean=27.8 mm,
N=30). Lengths for multi-year recaptured females were larger in 1987 (mean=26.9
mm, N=10) and 1989 (mean=30.6 mm, N=17) but slightly smaller in 1988
(mean=29.0 mm, N=20) than unmarked females. The weights of multi-year
recaptured males were nearly identical with unmarked males in 1988 (mean=1.6 g,
N=11), but multi-year recaptured females were substantially heavier (mean=2.3 g,
N=6) than unmarked females. In 1989, female weight was nearly identical
between marked and unmarked (mean=2.2 g, N=17) animals, whereas unmarked
males weighed more than multi-year recaptured males (mean=1.6 g, N=30). The
sex ratio of multi-year recaptured animals in 1987 was one female per 1.3 males;
in 1988, one female per 1.35 males; and in 1989, one female per 1.76 males.
