O conceito de bioma [PDF]

Acta Botanica Brasilica, 2006
O termo fitofisionomia foi proposto praticamente ao mesmo tempo que o termo formação. O termo bioma, proposto mais tarde, apenas adicionou a fauna à uniformidade fitofisionômica e climática, características desta unidade biológica. Várias modificações conceituais foram apresentadas por diversos autores, ao longo do tempo, acrescentando outros fatores ...
