Summary
This dataset includes total phosphorus (TP), total nitrogen (TN), and total carbon (TC) concentrations as well as δ15N and δ13C composition, and overall C:N:P stoichiometry for adult emergent Diptera from the Colorado River, Grand Canyon, AZ. The samples were collected before and after a fire and subsequent storm occurred in the Shinumo Watershed, a tributary to the Colorado River in Northern Arizona. Diptera specimens were collected via light traps placed on the banks of the Colorado River 25 miles above and 25 miles below Shinumo Creek (river miles 85-135) between 2013 and 2015. This data series contains Diptera TP concentrations (in mg P per mg Diptera) for 44 samples from 11 location/date combinations. We also report TN and TC [...]

The samples were collected before and after a fire and subsequent storm occurred in the Shinumo Watershed, a tributary to the Colorado River in Northern Arizona.

This data series contains Diptera TP concentrations (in mg P per mg Diptera) for 44 samples from 11 location/date combinations. We also report TN and TC concentrations (in mg TN or TC per mg Diptera) and δ15N and δ13C for 9 single samples. Average TC, TN, and TP concentrations were then compared for 8 date/location combinations to estimate C:N:P stoichiometry of Diptera samples.

Purpose
The purpose of this dataset is to report the concentrations of total phosphorus, nitrogen, and carbon in adult emergent Diptera from the Colorado River near Shinumo Creek (Grand Canyon). The data were collected in order to assess differences in Diptera nutrient assimilation, nutrient stoichiometry, and carbon (C) and nitrogen (N) isotope composition after a fire and subsequent storm occurred in the Shinumo Creek watershed, a tributary to the Colorado River. These data could be useful to researchers interested in the natural variation in macroinvertebrate nutrient concentrations and isotopic signatures. It could also be useful in informing site specific (Colorado River) food web and bioenergetic investigations.
