Enthusiasm for Orchids by John Alcock
Book DescriptionThe male thynnine wasp's extreme sexual enthusiasm is crucial to reproduction of hammer orchids in the wild. Hammer orchids have co-evolved to produce odors identical to those manufactured by female thynnine wasps. The male wasp's superb sensitivity to the scent of his female mate is the basis for the hammer orchid's deceit--in effect, orchids exploit the male insect's highly adaptive sense of smell for their own propogation. While pollinating orchids is a waste of time, and thus a maladaptive activity for a wasp, his mistake comes about because he must react quickly whenever he senses a possible mate nearby. Alcock suggests that, "for insects, he who hesitates is lost, although perhaps it would be better to say that he who hesitates often loses a chance to pass on his genes." This book abounds with clever explanations for how these exceptionally complex flowers came to be shaped as they are. The reader can explore many aspects of orchid biology and history ranging from how some species avoid inbreeding, to the origins of orchids from an ancestor that belonged to the asparagus family. Examining each component of an orchid's flower, Alcock explains how the various parts work together to produce the plant's minute offspring. Each element of an orchid, as quirky as it may seem, is biologically significant, bearing the imprint of natural selection. Readers can share in the delight that Darwin and all other orchid enthusiasts have felt in making sense of even the smallest of details of these most wonderful plants.

Exploring Animal Behavior, Paperback (August 2013)
This anthology contains 37 articles published since 1974 in American Scientist, the journal of the scientific society Sigma Xi. The richly illustrated articles provide a picture of how behaviourists think about and conduct their research, as well as insights into the behaviour of selected vertebrate and invertebrate species.
Animal Behavior, Paperback (July 2013)
The tenth edition features a major reorganisation, focusing first on the evolutionary basis of behavior followed by the underlying proximate mechanisms. Enduring features of previous editions also remain; the clear engaging writing style, the beautifully illustrated text with many new photographs and numerous references to new scientific articles.
Triumph of Sociobiology, Paperback (March 2003)» View all books by John Alcock
Looks at how sociobiologists study behavior in all species. This work provides an analysis of case histories that involve such topics as sexual jealousy, beauty, gender difference, parent-offspring relations, and rape. It shows that sociobiology provides satisfactory evolutionary analysis of social behavior.

Author Biography - John Alcock
Dr. Alcock's research deals with the evolution of diversity in insect mating systems. He studies selected species of desert insects in Arizona and Western Australia, in an attempt to document the variety of male mate-locating techniques in various bees, wasps, butterflies, dragonflies, and other insects. The goal of his research is to test hypotheses on the adaptive value of the different ways in which males find mating partners.
