Explore alternative breeding strategies in a 44-minute lecture from Yale University's "Principles of Evolution, Ecology and Behavior" course. Examine how breeding strategies vary among males and females of the same species and across different species, often linked to frequency dependence. Discover how species at evolutionary equilibrium maintain equal fitness across diverse strategies. Investigate examples from bullfrogs, figs, fig wasps, and wrasse fish, including "sneaky copulators." Learn about gamete-related behaviors and their evolutionary implications. Gain insights into the complex world of reproductive strategies in nature through this comprehensive exploration of alternative breeding methods.
