Far more than an aquarium adornment, the guppy has been at the cutting edge
of evolutionary ecology for many years. Anne Houde鈥檚 well-written and
excellently referenced book explores the evolution and natural history of one of
the tropic鈥檚 most colourful and familiar fish. With few concessions to popular
science, Sex, Color and Mate Choice in Guppies probably requires readers to have
an undergraduate foundation course in genetics and evolutionary theory for full
enjoyment. Published by Princeton University Press, 拢14.95/$19.95,
