The search for a topographic signature of life

  title={The search for a topographic signature of life},
  author={William E. Dietrich and J. Taylor Perron},
Landscapes are shaped by the uplift, deformation and breakdown of bedrock and the erosion, transport and deposition of sediment. Life is important in all of these processes. Over short timescales, the impact of life is quite apparent: rock weathering, soil formation and erosion, slope stability and river dynamics are directly influenced by biotic processes that mediate chemical reactions, dilate soil, disrupt the ground surface and add strength with a weave of roots. Over geologic time, biotic… 
Climate and the Pace of Erosional Landscape Evolution
Earth's climate affects nearly all aspects of landscape evolution, from the breakdown of rock to the delivery of sediment to the oceans. Yet quantifying climate's influence on landscapes is a major
Human topographic signatures and derived geomorphic processes across landscapes
Evidence for biotic controls on topography and soil production
Geomorphometric characterisation of natural and anthropogenic land covers
AbstractThe scientific community has widely discussed the role of abiotic and biotic forces in reshaping the Earth’s surface. Currently, the literature is debating whether humans are leaving a
Climatic and anthropogenic effects on soil transport rates and hillslope evolution
Vegetation change, whether it be of anthropogenic or climatic origin, can have dramatic effects on landscape form, processes and sediment yield. General conceptual models for relationships between
Arid geomorphic processes revealed by erosion of pre -Columbian archaeological earthworks in southern Peru
Earthworks of assumed age and their initial and current morphologies provide an ideal basis for developing and testing models for long-term landform erosion. Inca agricultural terraces abandoned at
Modelling landscape evolution
Geomorphology is currently in a period of resurgence as we seek to explain the diversity, origins and dynamics of terrain on the Earth and other planets in an era of increased environmental
Bedrock composition regulates mountain ecosystems and landscape evolution
Thealyses presented here show that differences in forest cover can be explained by variations in geochemical composition of underlying bedrock, demonstrating that bedrock geochemistry is on par with climate as a regulator of vegetation in the Sierra Nevada and likely in other granitic mountain ranges around the world.


Vegetation-modulated landscape evolution: Effects of vegetation on landscape processes, drainage density, and topography
[1] Topography acts as a template for numerous landscape processes that include hydrologic, ecologic, and biologic phenomena. These processes not only interact with each other but also contribute to
The illusion of diffusion: Field evidence for depth-dependent sediment transport
Soil-covered upland landscapes are common in much of the habitable world, and our understanding of their evolution as a function of different climatic, tectonic, and geologic regimes is important
Fire and the evolution of steep, soil-mantled landscapes
Recent burns in the western United States attest to the signif- icant geomorphic impact of fire in mountainous landscapes, yet we lack the ability to predict and interpret fire-related erosion over
Modeling the effects of vegetation‐erosion coupling on landscape evolution
[1] From rainfall interception at the canopy to added soil cohesion within the root zone, plants play a significant role in directing local geomorphic dynamics, and vice versa. The consequences at
Landsliding and the evolution of normal‐fault‐bounded mountains
Much of the tectonic and climatic history in high-relief regions, such as the mountains of the western U.S. Basin and Range province, is contained in the morphology of hillslopes, drainage networks,
Stochastic processes of soil production and transport: erosion rates, topographic variation and cosmogenic nuclides in the Oregon Coast Range
Landscapes in areas of active uplift and erosion can only remain soil‐mantled if the local production of soil equals or exceeds the local erosion rate. The soil production rate varies with soil
Erosional dynamics, flexural isostasy, and long-lived escarpments: A numerical modeling study
Erosional escarpments are common features of high-elevation rifted continents. Fission track data suggest that these escarpments form by base level lowering and/or marginal uplift during rifting,
Hillslope processes, drainage density, and landscape morphology
Catchment morphology and drainage density are strongly influenced by hillslope processes. The consequences of several different hillslope process laws are explored in a series of experiments with a
The soil production function and landscape equilibrium
Hilly and mountainous landscapes are partially to completely covered with soil under a wide range of erosion and uplift rates, bedrock type and climate. For soil to persist it must be replenished at
Orogeny and orography: The effects of erosion on the structure of mountain belts
A numerical model of the coupled processes of tectonic deformation and surface erosion in convergent orogens is developed to investigate the nature of the interaction between these processes. Crustal
