Buch. Zustand: Neu. Neuware - Providing coverage of sand-wasp tribes, this work offers a tribe-by-tribe, species by species review of studies of the Bembicinae. It is intended for those working on solitary wasps and serves as a useful reference for scientists interested in insect behavioural evolution.

Buch. Zustand: Neu. Neuware - Ramsey describes the constitutional law of foreign affairs derived from an historical understanding of the Constitution's text. Examining recurring foreign affairs controversies such as the power to enter armed conflict, the author shows how the words, structure, and context of the Constitution can resolve pivotal court cases and modern disputes.

Buch. Zustand: Neu. Neuware - In the crab spider, Misumena vatia, Douglass H. Morse and his colleagues found an ideal species on which to test basic questions associated with lifetime fitness. From the moment a female crab spider selects a flower on which to sit and wait for her prey, there unfolds a cascade of lifetime fitness variables that determine her evolutionary success. Did she choose a flower that attracts suitable prey Will she encounter a competitor or predator Will she survive long enough to breed, and will her offspring contribute to the gene pool Ecologists had previously identified variables that shape populations, but lacked the experimental data needed to make comprehensive tests of individuals that made different foraging decisions. Morse found that Misumena is particularly well suited to both field study and laboratory experiments. Over the last 25 years, his simple yet elegant experiments have contributed to our understanding of lifetime fitness and helped to develop study techniques that can be applied to animals with other, more complex, life histories. Predator upon a Flower recounts these influential discoveries in a gracefully crafted narrative that moves ever outward from individuals to communities to ecosystems, and concludes by suggesting directions for future research in spider biology.
