"The ghost of Robert H. MacArthur continues to haunt community ecology. In the 1960s, MacArthur and his colleagues revolutionized community ecology by developing simple but effective models of species interactions based on the unifying principles of competitive exclusion and the ecological niche. . . . [T]he most profound challenge to MacArthur's work came from experimental ecologists. . . . [T]hese ecologists added and removed species in communities, monitored the result, and evaluated the models in this light. . . . Experimental ecology has since developed rapidly, and ecologists have carried out sophisticated manipulative experiments in terrestrial, marine, and freshwater habitats. Experimental Ecology . . . is an edited volume with 22 contributions from the leaders of experimental ecology. . . . This symposium volume gives a state-of-the-art look at experimental ecology. . . . [T]his book was thought-provoking and enjoyable. I highly recommend it to all ecologists." BioScience
