Loss of deep roots limits biogenic agents of soil development that are only partially restored by decades of forest regeneration
Roots and associated microbes generate acid-forming CO2 and organic acids and accelerate mineral weathering deep within Earth’s critical zone (CZ). At the Calhoun CZ Observatory in the USA’s Southern Piedmont, we tested the hypothesis that deforestation-induced deep root losses reduce root- and microbially-mediated weathering agents well below maximum root density (to 5 m), and impart land-use legacies even after ~70 y of forest regeneration. In …
The Anthropocene is functionally and stratigraphically distinct from the Holocene
Evidence of an Anthropocene epoch Humans are undoubtedly altering many geological processes on Earth—and have been for some time. But what is the stratigraphic evidence for officially distinguishing this new human-dominated time period, termed the “Anthropocene,” from the preceding Holocene epoch? Waters et al. review climatic, biological, and geochemical signatures of human activity in sediments and ice cores. Combined with deposits of new mater…
Colonization of the Americas, 'Little Ice Age' climate, and bomb-produced carbon
A recently published analysis by Lewis and Maslin (Lewis SL and Maslin MA (2015) Defining the Anthropocene. Nature 519: 171-180) has identified two new potential horizons for the Holocene−Anthropocene boundary: 1610 (associated with European colonization of the Americas), or 1964 (the peak of the excess radiocarbon signal arising from atom bomb tests). We discuss both of these novel suggestions, and consider that there is insufficient stratigraph…
The Accrual of Land Use History in Utah's Forest Carbon Cycle
The out-of-control global carbon cycle is driven not only by greenhouse gas emissions from fossil-fuel combustion but also from accelerated carbon cycling through human-impacted ecosystems. Here I estimate that forests in Utah are currently accumulating atmospheric carbon in biomass, detritus, and soil largely in response to 150 years of domestic livestock grazing, altered fire regimes, and logging. I attribute forest-carbon accumulation, which r…
