XXIX. 372 In paleo-ecology the concept of the biome, or biotic community, seems to have peculiar value, as it directs special attention to the causal relations and reactions of the three elements—habitat, plant, and animal. Ibid. 374 Climatic changes and biotic movements..are involved in..the appearance of new biomes and the disappearance of preceding ones. 1931Ecology XII. 456 Because the larger and more influent animals tend to range throughout units of largest (formational) size including their seral stages, the biome or biotic formation is the natural ecological unit with some properties which are well illustrated by comparison with an organism. 1935Ibid. XVI. 399 Migratory species..are frequently seasonal influents classed in seasonal communities in two biomes. 1957G.
