| Abstract: | Previous studies have proposed that species within the genus Galago exhibit a secondary sex ratio that is strongly skewed (approximately 70%) in favour of males. It has further been suggested that this sex ratio is maintained into adulthood. We present data obtained from 669 adult galagos, representing eight wild populations and five species, to indicate that the sex ratio among sexually mature individuals is close to parity. If the observations regarding sex ratios at birth are correct, this implies that juvenile/sub-adult males suffer significantly higher mortalities than do their female counterparts. |
