  19. Mammalian Reproduction Modes • Prototherians (monotremes) • Oviparous • Hatchlings mature in pouch and suckle from mammary gland • Metatherians (marsupials) • Vivparous • Very immature young mature in pouch and suckle from mammary gland • Eutherian (placentals) • Vivaparous • Precocial & altricial young • Suckle young

  20. Reproductive Cycles • Estrous cycle • Time of ovulation following a peak in estrogen production (estrus) • Monestrous • 1 ovulation period per year • Polyestrous • Multiple ovulation periods per year • Menstrual cycle • Estrus followed by menstruation • Shedding of uterine lining • Only in humans, apes, & old world monkeys

  22. Gestational & Lactational Differences between Marsupials & Mammals

  23. Gestation Periods • Large mammals (herbivores) • Longer gestations • Precocial newborns • Small insectivores, rodents, carnivores • Shorter gestations • Altricial newborns • Sightless • Hairless
