摘要: I investigated the scale and pattern of mortality among feral cattle ( Bos taurus ) occurring on Amsterdam Island in 1988 to test hypotheses related sexual dimorphism. Because are sexually dimorphic ungulates all deaths apparently were due starvation, was expected be biased towards males. Mortality juvenile males higher than that females (22.4 versus 11.7%), but adult lower (18.3 47.7%). Causes for differential survival age-classes uncertain, could involve sex differences use habitat, or consequences previous selection during domestication.
