Data and R code from: Resource quantity and quality co-limit consumer production in forest streams

This dataset includes estimates of annual secondary production (mg ash-free dry mass/m2/yr) of macroinvertebrate communities (total community=Tot, primary consumers=Prim, and leaf-shredding invertebrates=Shred) in several small forest streams located at the Coweeta Hydrologic Laboratory in North Carolina, USA. Accompanying each estimate of annual secondary production are estimates of mean annual discharge (Q, L/s), soluble reactive phosphorus (SRP, μg/L) and dissolved inorganic nitrogen (DIN, μg/L) concentrations and mean annual leaf litter standing stock (avgLeaf.core, g ash-free dry mass/m2). Additionally estimates of average %N (N) and %P (P) of leaf litter are included for each stream and year of study. These data are from three separate, multi-year projects aimed at assessing the impacts of experimental whole-stream N and P additions on stream communities and ecosystems conducted between 1999-2001, 2003-2004, 2010-2013.

Methods
This datasets compiles data from three previously published studies of the effects of experimental N and P fertilization in small, forest streams at the Coweeta Hydrologic Laboratory in Macon County, North Carolina, USA. Associated methods can be found in the original papers (citations below).
