Variable Variation: Annual and Seasonal Changes in Offspring Sex Ratio in a Bat

  title={Variable Variation: Annual and Seasonal Changes in Offspring Sex Ratio in a Bat},
  author={Robert M. R. Barclay},

Many organisms produce offspring with sex-ratios that deviate from equal numbers of males and females, and numerous adaptive explanations have been proposed. In some species, offspring sex-ratio varies across the reproductive season, again with several explanations as to why this might be adaptive. However, patterns for birds and mammals are inconsistent, and multiple factors are likely involved. Long-term studies on a variety of species may help untangle the complexity. I analyzed a long-term… CONTINUE READING
