Retention of nitrogen (N) is a critical ecosystem function, especially in the face of widespread anthropogenic N enrichment; however, our understanding of the mechanisms involved is limited. Here, we tested under glasshouse conditions how plant community attributes, including variations in the dominance, diversity and range of plant functional traits, influence N uptake and retention in tempera...

Stormwater wet ponds (SWPs) are engineered structures used to collect and retain stormwater runoff from developed areas. SWPs generally regarded as important nitrogen (N) sinks, but seasonal variation in SWP N cycling that influences pond removal has not been characterized. To inform function across seasons, we sampled the sediments water columns of three southeastern US coastal plain measured ...

A combined proteomic and isotope tracer approach was used to investigate the impact of supplying N as glycine to roots of Lolium perenne. Initially, ammonium nitrate was supplied to all plants, after which half received glycine as their sole N source, while the remainder continued to receive ammonium nitrate. Plants supplied with glycine acquired less N than those receiving the mineral source, ...
