Estudo comparativo de ninhadas de Bothrops moojeni (Serpente, Viperidae) em cativeiro

Abstract

The main objective of this work was to evaluate data on birth of Bothrops moojeni newborns from the Laboratory of Herpetology at Instituto Butantan, in the period of 2002 and 2021, in order to establish relationships between different litters. For this study, females of Bothrops moojeni admitted from the wild, and females born in captivity were compared and analyzed. All females and their offspring had their data collected and analyzed, regarding the proportion of males and females per litter, mass, size, fertility rate, mortality, correlations about mother size and mass, number of offspring and relative litter mass. No significant relationship between maternal investment indices of females in relation to their size and mass were found, however the number of newborns was positively influenced by the body size of females. Data such as average gestation time, time of birth and number of newborn per litter found, were close to data recorded in literature.
