RELATIONSHIP BETWEEN IN UTERO PRODUCTIVITY OF MOOSE AND POPULATION SEX RATIOS: AN EXPLORATORY ANALYSIS
We investigated the in utero productivity of moose (Alces alces) in the central interior of British Columbia from 1981 to 1990. Variations in the ovulation, fertilization, fetal and in-utero twinning rates were correlated to adult sex ratios. Significant correlations between the fetal rates and bull...

Summary: | We investigated the in utero productivity of moose (Alces alces) in the central interior of British Columbia from 1981 to 1990. Variations in the ovulation, fertilization, fetal and in-utero twinning rates were correlated to adult sex ratios. Significant correlations between the fetal rates and bull:cow ratios as well as between the twinning rates and bull:cow ratios are presented. Implications of these relationships on moose management and harvest strategies are discussed. |
