Abstract

The reproductive cycle of snakes are coordinate evolutionarily for genetic factories and synchronize by seasonal weather (four seasons). In the tropical regions, the cold of winter is less marked than temperate zones and there is a diversity microclimate inside of biome. It's uncertainty if the difference of temperature and rainfall are capable to change the reproductive cycle in the specie and if these species has plasticity to modify their reproductive strategies. The aim of this research was analyze the influence of climate variation in reproductive cycle of Micrurus corallinus e Micrurus frontalis inside of each specie and between both species. The reproductive cycle was examined by biometric and histology data from biological collections. The result attained with this search, indicate that M. corallinus have a plasticity to adapt the cycle according environment conditions. In addition, the result of this work there is the first confirmation of the reproductive strategy of sperm storage by females in genus Micrurus. (AU)
