Resumen:
We studied 20 nesting female Caimnan latirostris and their clutches in Santa Fe Province, Argentina. We regressed clutch and egg parameters and hatchling size with several measurements of female size (In-transformed) to evaluate the allometry of reproduction in the wild. Larger females produced relatively smaller clutches. Larger feniales produced larger eggs and hatchlings. Egg width, not length, limits egg size relative to female body size. Future studies should address the relationship between female fecundity and hatchling fitness.studied 20 nesting female Caimnan latirostris and their clutches in Santa Fe Province, Argentina.
