Andean uplift and consequences for species evolution in the Amazon drainage basin

Carina Hoorn

University of Amsterdam, Netherlands, The

The Neogene uplift of the Andes strongly influenced environments, geography, and climate through time. In combination with global climate, sea level change and dynamic topography, this process (re)shaped the biogeography of the Amazon drainage basin. The western Amazon, was formed by a vast wetland that was controlled by orbital forcing and episodic marine influence, with dispersal of coastal flora and fauna into the Amazon heartlands. As uplift accelerated, the effects extended across the continent, leading to the birth of the Amazon River and sediment transport across continent and into the Atlantic. The river formed a bridge and a barrier for biotic dispersal but also affected the coastal environment. Here I will review recent geological and paleobiological data to illustrate the effects of geological change on neotropical biogeography.
