Sex Differences and Evolution: Notes of a Darwinian Feminist (G,P)
Singing under Pressure: Acoustically-Orienting Parasitoids and their Cricket Hosts (G,S)
Parasites, Sexual Selection and Immune Function in Red Jungle Fowl (G,S)
Sexual Selection (G)

Marlene Zuk received her B.A. at the University of California, Santa Barbara, and obtained her Ph.D. from the University of Michigan. After doing postdoctoral work at the University of New Mexico, she took a position as associate professor of biology at the University of California at Riverside. Her research interests center on animal behavior, particularly mate choice and the evolution of sex differences; and the effects of parasites on host ecology and behavior. More recently, her longstanding commitment to feminism has dovetailed with her academic interests, particularly the relationship between feminism and science.
