Global change and root production: how does land use and climate change affect life belowground? — Uthara Vengrai

Posted on by Madeline Gupta

Roots do everything. They are the connector between plants and soil–the interface at which many of the transactions of life are made. Roots (with the help of their mycorrhizal associates) conduct a plant’s search for nutrients, water, and shelter. They scour the soil for the ingredients of life and support whole ecosystems of microorganisms, plants, Read more about Global change and root production: how does land use and climate change affect life belowground? — Uthara Vengrai[…]

The importance of a few places and a few organisms: soil methane fluxes in the West—Uthara Vengrai

Posted on by ucross-admin

Drylands cover about 40% of the world and the vast majority of the American West. They are expansive, diverse places all united by one thing: water limitation. These ecosystems are slow to build up carbon and slow to decompose it, which leaves rich pools of old carbon, the majority of which is stored in the Read more about The importance of a few places and a few organisms: soil methane fluxes in the West—Uthara Vengrai[…]

Impacts of global change and land use on biogeochemical dynamics in Southwestern Wyoming

Posted on by ucross-admin

Uthara’s research focuses on the interactive effect of global change scenarios and land use practices on soil carbon and nitrogen dynamics in sagebrush ecosystems of the American West. Drylands contain about 20% of the world’s carbon stock, with the majority being held in slow-cycling belowground pools. Despite playing a critical role in the global carbon Read more about Impacts of global change and land use on biogeochemical dynamics in Southwestern Wyoming[…]
