A dataset containing weight-batch fecundity relationships
for St. Johns, York, and Connecticut Rivers from Olney and McBride (2003).
Regressions fit log10 batch fecundity as a function of
log10 body weight (g).
A data frame with 3 observations of 4 variables:
system Study system
region Life-history region: NI = Northern iteroparous,
SI = Southern iteroparous, SP = Semelparous
alpha Intercept
beta Slope
