A method for estimating fall adult sex ratios from production and survival data A method for estimating fall adult sex ratios from production and survival data

This basic adult sex ratio is an average value derived from average production and survival rates. It is an estimate of the average sex ratio about which the fall adult ratios will fluctuate according to annual variations in production and...
