H092:
Plants as Builders and Plumbers of the Critical Zone





Session ID#: 24933

Session Description:
The critical zone (CZ) – Earth's permeable veneer from the tops of trees to the bottom of groundwater aquifers – is a constantly evolving layer where rock, soil, water, air, and living organisms interact, regulating habitats and determining the availability of life-sustaining resources, including food production and water quality. Like an elaborate piece of industrial machinery, plants build the CZ by altering the physical architecture and chemistry of the subsurface. Like a complex network of pipes, plants plumb the CZ by impacting reservoirs and pathways of water and nutrients. We solicit contributions that explore plants’ effects on the CZ and the CZ’s effects on plants. We are interested in abstracts contributing to understanding the evolving relationships of plants and the CZ over multiple timescales: (1) complex plant-CZ relationships that regulate the flows of energy, water, carbon and nutrients and (2) how plant-CZ interactions and organization shape landscapes and sculpt soils.
