We investigated the effects of removing near-stream Rhododendron and of the natural blowdown of canopy trees on nutrient export to streams in the southern Appalachians. Transects were instrumented on adjacent...

Gaps in the forest canopy can increase the diversity of tree regeneration. Understory shrubs also compete with tree seedlings for limited resources and may depress tree recruitment. We compared effects of shrub...

Understanding and predicting the extent, location, and function of biogeochemical hot spots at the watershed scale is a frontier in environmental science. We applied a hydropedologic approach to identify (1)...

Nutrient uptake capacity is an important parameter in modeling nutrient uptake by plants. Researchers commonly assume that uptake capacity measured for a species can be used across sites. We tested this...

Elevated atmospheric CO2 may cause long-term changes in the productivity and species composition of the sagebrush steppe. Few studies, however, have evaluated the effects of increased CO2 on growth and...

We examined relationships between denitrification (DNF) and nitrous oxide (N2O) fluxes and potentially important chemical and physical predictors to build a predictive understanding of gaseous N losses from...

Sediment deposition is the main mechanism of nutrient delivery to tidal freshwater marshes (TFMs). We quantified sediment nutrient accumulation in TFMs upstream and downstream of a proposed water withdrawal...

In order to address the ecological and social problems of sustainability in our modern times, citizens need to be empowered with an understanding of science, technology, engineering, and math (STEM) concepts...

In Learning Gardens and Sustainability Education: Bringing Life to Schools and Schools to Life, Williams and Brown (2011) place living soil at the center of the discourse on sustainability education. One of the...

After we spread the chicken poop, we covered it with hay... the poop was the fertilizer and the hay was the stuff that kept the plaHts warm. After school l checked the garden. Empty. Nobody. I climbed the fence...
