标题：Edad, tamaño corporal en la madurez sexual, longevidad y potencial reproductivo de Leptodactylus latinasus y Leptodactylus mystacinus en un cultivo de soja y un bosque nativo del centro este de Argentina
摘要：Age and size at sexual maturity, longevity, and potential reproductive in 2 anuran species Leptodactylusmystacinus and Leptodactylus latinasus from a soybean crop (CS) and at the natural reserve Parque General SanMartín (PGSM) (Entre Ríos-Argentina) were estimated and compared using skeletochronology methods. L. latinasusdiffered (p< 0.01) in average age between sites. Sexual maturity was not observed in L. latinasus from CS while inL. mystacinus it was reached at 3 years in PGSM and 4 years at CS. Younger anurans of PGSM begin to reproduceearlier respect to findings in soybean crop.
