Document Summary
Communication: definition, difference between signals and cues, learn the definition of honesty, deceit, eavesdropping, spite. The 4 main mating systems: monogamy, polygyny, polyandry, promiscuity. The 2 components of sexual selection: male-male competition and female choice. Relationship between differential parental investment, reproductive rate, variance in reproductive success, and degree of sexual selection. If you"re given a graph showing reproductive success or pictures of males and females, you should be able to predict the mating system of the species and explain why. The polygyny threshold model how females make decisions about resources versus parental care. Quality signals are honest because they are costly. How does male pickiness about a mate vary with mating system, parental care, variance in reproductive success. Polyandry learn and understand the benefits of polyandry for females. Understand how changing frequency of a strategy in the population (away from equilibrium) will change the reproductive success of the strategies.
