Nitrogen-bedrock interactions regulate multi-element nutrient limitation and sustainability in forests
Nutrient limitation of tree growth can intensify when nutrients are lost to forest harvest, creating challenges for forest growth and sustainability. Forest harvest accelerates nutrient loss by removing nutrie...

Extreme drought conditions increase variability of nitrate through a stream network, with limited influence on the spatial patterns of stream phosphate
Nutrient availability is an important control on ecosystem processes in streams. In this study, we explored how an extreme summer drought affected spatial patterns of nutrient availability along a fourth-order...

Decadal-scale decoupling of soil phosphorus and molybdenum cycles by temperate nitrogen-fixing trees
Symbiotic nitrogen- (N) fixing trees can influence multiple biogeochemical cycles by fixing atmospheric N, which drives net primary productivity and soil carbon (C) and N accumulation, as well as by mobilizing...

Nutrient feedbacks to soil heterotrophic nitrogen fixation in forests
Multiple nutrient cycles regulate biological nitrogen (N) fixation in forests, yet long-term feedbacks between N-fixation and coupled element cycles remain largely unexplored. We examined soil nutrients and he...

Contributions of dust to phosphorus cycling in tropical forests of the Luquillo Mountains, Puerto Rico
The input of phosphorus (P) through mineral aerosol dust deposition may be an important component of nutrient dynamics in tropical forest ecosystems. A new dust deposition calculation is used to construct a br...
