On the Young Savannas in the Land of Ancient Forests
Original language description
Covering an ancient geomorphological landscape, and surrounded by some of the most diverse forests on Earth, the Neotropical savannas were oncenperceived by naturalists as ancient environments. However, current evidence suggests that tropical forests have existed in the Neotropics since the Paleocene, and that most plant lineages present in South American savannas are recently derived from clades from the surrounding forested biomes. This chapter provides a multidisciplinary overview on the origin,nassembly and expansion of Neotropical savannas, with focus on South America. For this, we consider available evidence from the fossil record,npaleoenvironmental proxies (phytoliths), and phylogenetic information for both plants and animals. Paleoenvironmental reconstructions indicatensuitable climates for central South American savannas since the middle Miocene, which is also when molecular phylogenies are used to infer the origin of some vertebrate groups typical of savannas. Fossil data indicate the ecological expansion of both C3 and C4 grasses in southern South America by the late Miocene. Fossil information indicates the onset of savannas innnorthern South America during the Pliocene, a period in which most woody thought to have diversified, as inferred by dated phylogenies. Although the combined lines of evidence indicate that Neotropical savannas in South America are indeed younger than their surrounding forests, the precise timing and factors that influenced the origin, assembly and expansion ofnNeotropical savannas remain contentious. Future research should aim at (1) increasing and integrating knowledge about the diversification of important taxa characteristic to Neotropical savannas, (2) establishing continuous sequences of fossils, and (3) building accurate paleoenvironmental reconstructions for the entire Neogene.
