In this symposium international speakers will review how organisms not only respond to the Earth’s surface, but also directly modify and control it to promote their own persistence. Plants and animals can directly control the fluxes of energy and matter that underlie biogeochemical cycles, gas fluxes, sediment transport and form new habitats. Recent recognition of biotic interactions with Earth surface processes has led to a new Geoscience paradigm: The Earth’s surface is not only the product of tectonic forces (mountain building) and climate (destroying relief by weathering and erosion), but also through biotic processes that are active over micro- to macroscopic scales. Biota moderates tectonic and climate controls on surface processes and is an equally important player in shaping the Earth.
This symposium will review the findings that triggered this paradigm shift, for example that 1) the activity of biota extends to great depth (the “deep biosphere”); 2) soil development is related to plant diversity and burrowing animals; 3) plants diverge the flow and evaporation of water; 4) higher plants can induce the uptake of mineral nutrients that vastly exceeds the rock weathering of these elements; 5) vegetation moderates soil erosion; 6) large river floodplains are stabilized by plants.
