1. First record of growth rings for 11 native subtropical anuran species of South America
Abstract: Skeletochronology is the most accurate method to estimate a population age structure. The methodology is based on the analysis of secondary bone tissue in order to count growth rings. This study aimed to provide initial data, allowing researchers to further work out in the age of individuals and populations, sampling evidence of the presence of gro

2. Contrasting life-histories in two syntopic amphibians of the Leptodactylus fuscus group (Heyer 1978)
Abstract Abstract: We used skeletochronology to compare age, size, reproductive parameters and growth patterns of two related, anuran amphibians from Northern Argentina: Leptodactylus bufonius(n=69) andL. latinasus(n=56), in order to better understand their coexistence in syntopy. Previous studies showed that the two species overlap in their dietary requirem

3. Idade e crescimento da tartaruga-cabeçuda (Caretta caretta) no litoral sul do Rio Grande do Sul / Age and growth of loggerhead sea turtle (Caretta caretta) in Southern Brazil
The juvenile and sub-adult stages of loggerhead sea turtles (Caretta caretta) are poorly studied in Brazil. We present age estimates and a growth model for loggerhead sea turtles in the South Atlantic Ocean obtained through skeletochronological analysis of humeri obtained from both neritic and oceanic stage individuals. Since it was validated that each incre
