The history of ecology: achievements and opportunities, part two.

Among ecologists, historians of science, and environmentalists there is growing interest in the history of ecology. The editor of theJournal of the History of Biology therefore requested that I write a new bibliographic essay to supplement the one published in 1977. My earlier essay, which covered relevant writings from ancient to recent times, concentrated on general ecology and population ecology. The present article, limited to the 19th and 20th centuries, covers the general history of ecology, terrestrial plant ecology, marine ecology, limnology, population ecology, and animal ecology. In Part Two I shall survey the history of applied ecology in North America.
