Our goal for creating this digital reference collection is to provide regional aquatic biology labs with a graphic tool to aid in the identification and verification of aquatic macroinvertebrates. Most aquatic labs possess a collection of ‘reference’ specimens so that technicians/ taxonomists may compare and confirm specimens collected from a sample with expertly identified and verified type specimens of a particular taxa type. Unfortunately, specimens in these collections are often delicate and subject to damage, eventually rendering them unusable for verification purposes. Because of the unstable nature of individual type specimens, the Aquatic Experimental Lab at the Fort Collins Science Center has developed...

Carbon, nitrogen, and phosphorus content of adult emergent Diptera before and after a fire-storm sequence in the Colorado River near Shinumo Creek, Grand Canyon, AZ

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...
