Spatial variability of African dust in soils in a montane tropical landscape in Puerto Rico

Creator:: McClintock, M. A., Brocard, G., Willenbring, J., Tamayo, C., Porder, S., and Pett-Ridge, J. C.
Abstract:: Dust deposition provides rock-derived nutrients such as phosphorus (P) to terrestrial ecosystems. Over pedogenic timescales, as bedrock sources of P are depleted, dust sources of P may support productivity in certain ecosystems, but controls on the spatial variability of dust in montane forested systems are largely unknown. Here, we use...

Response of the nitrogen-fixing lichen Lobaria pulmonaria to phosphorus, molybdenum, and vanadium

Creator:: Marks, Jade A., Pett-Ridge, Julie C., Perakis, Steven S., Allen, Jessica L., and McCune, Bruce
Abstract:: Nitrogen-fixing lichens (cyanolichens) are an important source of nitrogen (N) in Pacific Northwest forests, but limitation of lichen growth by elements essential for N fixation is poorly understood. To investigate how nutrient limitation may affect cyanolichen growth rates, we fertilized a tripartite cyanobacterial lichen (Lobaria pulmonaria) and a green algal...

Mineral protection of soil carbon counteracted by root exudates

Creator:: Keiluweit, Marco, Bougoure, Jeremy J., Nico, Peter S., Pett-Ridge, Jennifer, Weber, Peter K., and Kleber, Markus
Abstract:: Multiple lines of existing evidence suggest that climate change enhances root exudation of organic compounds into soils. Recent experimental studies show that increased exudate inputs may cause a net loss of soil carbon. This stimulation of microbial carbon mineralization ('priming') is commonly rationalized by the assumption that exudates provide a...

Nano-scale investigation of the association of microbial nitrogen residues with iron (hydr)oxides in a forest soil O-horizon

Creator:: Keiluweit, Marco, Bougoure, Jeremy J., Zeglin, Lydia H., Myrold, David D., Weber, Peter K., Pett-Ridge, Jennifer, Kleber, Markus, and Nico, Peter S.
Abstract:: Amino sugars in fungal cell walls (such as chitin) represent an important source of nitrogen (N) in many forest soil ecosystems. Despite the importance of this material in soil nitrogen cycling, comparatively little is known about abiotic and biotic controls on and the timescale of its turnover. Part of the...
