Photochemical Degradation of Strong Natural Iron-Binding Ligands in the California Current Ecosystem

Poster Number:  388 Presenter/Primary Author:  Randelle Bundy The speciation of iron has been shown to be significantly affected by photochemical processes in the surface ocean, altering both the redox state and organic complexation of iron.

Does Crop Rotation Influence Soil Microbial Function?

Poster Number:  344 Presenter/Primary Author:  Marshall McDaniel Crop rotations, which increase plant diversity through time, are considered key to sustainable agroecosystem management.  Crop rotations have been shown to alter soil carbon (C) and nitrogen (
