Applications of sexual selection theory to humans lead us to expect that because of mammalian sex differences in obligate parental investment there will be gender differences in fitness variances, and males will benefit more than females from multiple mates. Recent theoretical work in behavioral ecology suggests reality is more complex. In this paper, focused on humans, predictions are derived ...

Bateman's experimental study of Drosophila melanogaster produced conclusions that are now part of the bedrock premises of modern sexual selection. Today it is the most cited experimental study in sexual selection, and famous as the first experimental demonstration of sex differences in the relationship between number of mates and relative reproductive success. We repeated the experimental metho...

In this paper, we present some monogamy relations of multiqubit quantum entanglement in terms the $$\beta $$ th power concurrence, formation and convex-roof extended negativity. These are proved to be tighter than existing ones, together with detailed examples showing tightness.
