dc.description.abstractFêmeas ovígeras de U. thayeri e de U. uruguayensis foram utilizadas para se avaliar e comparar o padrão reprodutivo. O tamanho médio das fêmeas foi de 6,6 ± 0,8mm para U. uruguayensis, variando de 17,3 ± 4,4mm para U. thayeri. A fecundidade média obtida para U. uruguayensis foi 1883 ± 490 ovos (N = 27) e para U. thayeri de 31068 ± 11185 ovos (N = 31). As diferenças observadas no padrão reprodutivo de U. thayeri e U. uruguayensis sugerem estratégias adaptativas: U. thayeri apresenta uma reprodução sazonal, com atividade pronunciada de janeiro a março e alta fecundidade, enquanto U. uruguayensis reproduz-se continuamente, mas com proles menores.
dc.description.abstractOvigerous females of Uca thayeri and U. uruguayensis were used to achieve and compare their reproductive pattern. The females mean size was 6.6 ± 0.8mm for U. uruguayensis and 17.3± 4.4mm for U. thayeri. The mean fecundity obtained for U. uruguayensis was 1883 ± 490 eggs (N = 27) and for U. thayeri was 31068 ± 11186 eggs (N = 31). The differences observed in reproductive pattern of U. thayeri and U. uruguayensis suggest an adaptive strategy by each species: U. thayeri presented seasonal reproduction with a pronounced intensity from January to March and higher fecundity, while U. uruguayensis reproduction was continuous all year round, but with lower fecundity.
