The Social Behavior of the Bees - Charles D. Michener - Bog - Harvard University Press - Plusbog.dk

The Social Behavior of the Bees - Charles D. Michener - Bog - Harvard University Press - Plusbog.dk

Although the honeybee is without doubt man's favorite social insect, and the most studied by him, there are twenty thousand other species of bees, many of which are social. This book is the first to offer a systematic account of social behavior in the entire super family Apoidea. Of all the social insects, the various species of bees exhibit perhaps the broadest spectrum of social behavior, including intermediate stages which are scarce or totally extinct in other groups; in this respect the bees are particularly appropriate subjects for evolutionary study. With the aid of more than 200 illustrations, Charles Michener characterizes and describes all levels of social organization in the bees—from simple aggregations of solitary nests to elaborate, eusocial colonies. He reviews the entire repertoire of social behavior in bees and gives detailed attention to mechanisms of communication, division of labor, determination of sex and caste, maintenance and control of nest conditions, and organization of defense. In a major chapter the evolutionary context of the bee societies is extensively explored; the author examines the selective advantages and disadvantages entailed in evolving nonreproductive castes, the problem of multiple, independent origins of eusociaI behavior, and the question of “direction” in the evolution of social behavior. The final section is an account of the life history and behavioral attributes of each of the groups of social bees.

No Property in Man - Sean Wilentz - Bog - Harvard University Press - Plusbog.dk

No Property in Man - Sean Wilentz - Bog - Harvard University Press - Plusbog.dk

“Wilentz brings a lifetime of learning and a mastery of political history to this brilliant book.”—David W. Blight, author of Frederick DouglassA New York Times Book Review Editors’ ChoiceA Foreign Affairs Best Book of the YearAmericans revere the Constitution even as they argue fiercely over its original toleration of slavery. In this essential reconsideration of the creation and legacy of our nation’s founding document, Sean Wilentz reveals the tortured compromises that led the Founders to abide slavery without legitimizing it, a deliberate ambiguity that fractured the nation seventy years later. Contesting the Southern proslavery version of the Constitution, Abraham Lincoln and Frederick Douglass pointed to the framers’ refusal to validate what they called “property in man.” No Property in Man has opened a fresh debate about the political and legal struggles over slavery that began during the Revolution and concluded with the Civil War. It drives straight to the heart of the single most contentious issue in all of American history. “Revealing and passionately argued…[Wilentz] insists that because the framers did not sanction slavery as a matter of principle, the antislavery legacy of the Constitution has been…‘misconstrued’ for over 200 years.”—Khalil Gibran Muhammad, New York Times“Wilentz’s careful and insightful analysis helps us understand how Americans who hated slavery, such as Abraham Lincoln and Frederick Douglass, could come to see the Constitution as an ally in their struggle.”—Eric Foner
