Chapter 10 Opener: The female (left) and the male (right) of the gorgeous lizard

10.1 Bowerbird courtship revolves around the bower

10.2 Evolutionary relationships among 15 populations of bowerbirds

10.3 Different bowers in different populations of the same bowerbird species

10.4 Bower building may be an indicator of brain size

10.5(1) Variance in reproductive success is greater for males than females in the satin bowerbird

10.5(2) Variance in reproductive success is greater for males than females in the satin bowerbird

10.6 Male and female gametes differ greatly in size

10.7 Parental investment takes many forms

10.8 Sexual behavior differences between sexes may arise from differences in parental investment

10.9 Male sex drive is intense

10.10 A sex role reversal in which females, not males, advertise for mates

10.11(1) Phylogenetic relationship between complex parental care by males and sex role reversal

10.11(2) Phylogenetic relationship between complex parental care by males and sex role reversal

10.15 Sexually selected “ornaments” of males

10.16 Males of many species fight, using whatever weapons they have at their disposal

10.17 Dominance usually correlates strongly with reproductive success in savanna baboons

10.18 Dominant male baboons fail to control fertile females as completely as expected (Part 1)

10.18 Dominant male baboons fail to control fertile females as completely as expected (Part 2)

10.21 Satellite male mating tactics

10.22 A conditional strategy model in the horseshoe crab

10.24 Three different forms of the sponge isopod

10.25 Three different egg fertilization behaviors coexist in the bluegill sunfish

10.26 A male black-winged damselfly removes a rival’s sperm before transferring his own

10.27 Sperm competition has shaped the evolution of the black-winged damselfly’s penis

10.28 Sperm competition in the dunnock requires female cooperation

10.29 The reproductive anatomy of fertilization in birds

10.35 A potential nuptial gift

10.36 Sperm transfer and the size of nuptial gifts

10.37 Sexual suicide in the redback spider

10.40 A sexually selected ornament

10.41 Has cryptic female mate choice resulted in the evolution of stimulating male genitalia?

10.44 Do male ornaments signal good genes? (Part 1)

10.44 Do male ornaments signal good genes? (Part 2)

10.45 Chase-away selection theory
