Changing the climate conversation in Arizona

NAU joins with ASU, UA and Arizona communities to confront climate crisis As Arizona confronts the impacts of a hotter world, Northern Arizona University is joining partners from Arizona State University, the University of Arizona and communities from throughout the state to convene the first statewide, solutions-focused climate summit.

Ecogeomorphic feedbacks in regrowth of travertine step-pool morphology after dam decommissioning, Fossil Creek, Arizona

The linkages between fluvial geomorphology and aquatic ecosystems are commonly conceptualized as a one-way causal chain in which geomorphic processes create the physical template for ecological dynamics. In streams with a travertine step-pool morphology, however, biotic processes strongly influence the formation and growth of travertine dams, creating the potential for […]

Interactions between geomorphology and ecosystem processes in travertine streams–implications for dam decommissioning in Fossil Creek, Arizona.

Travertine deposits of calcium carbonate can dominate channel geomorphology in streams where travertine deposition creates a distinct morphology characterized by travertine terraces, steep waterfalls, and large pools. Algae and microorganisms can facilitate travertine deposition, but how travertine affects material and energy flow in stream ecosystems is less well understood. Nearly […]
