Such movements are revealed by trapping procedures that yield deviations from the expected 1:1 sex ratio.

Of course, such hiatuses are to be expected; even in man such enigmas as the disparate sex ratio still challenge the investigator.

I regard the summer sex ratio as a distorted one, brought about by the greater activity of the males in the breeding season.

Judging from trends in the small samples available, sex ratio in hatchlings is approximately 1:1.

Even the sex ratio of adult deer killed in wolf-free areas shows a preponderance of males (Erickson et al. 1961).
