Abstract This study compared patterns of δ15N and δ13C enrichment of pallid sturgeon Scaphirhynchus albus and shovelnose sturgeon S. platorynchus in the Missouri River, United States, to infer their trophic position in a large river system. We examined enrichment and energy flow for pallid sturgeon in three segments of the Missouri River (Montana/North Dakota, Nebraska/South Dakota, and Nebraska/Iowa) and made comparisons between species in the two downstream segments (Nebraska/South Dakota and Nebraska/Iowa). Patterns in isotopic composition for pallid sturgeon were consistent with gut content analyses indicating an ontogenetic diet shift from invertebrates to fish prey at sizes of >500-mm fork length (FL) in all three segments of the Missouri River. Isotopic patterns revealed shovelnose sturgeon did not experience an ontogenetic shift in diet and used similar prey resources as small (<500-mm FL) pallid sturgeon in the two downstream segments. We found stable isotope analysis to be an effective tool for evaluating the trophic position of sturgeons within a large river food web.

One of the consequences of the Missouri Basin development program will be the virtual obliteration of the Missouri River between Yankton, South Dakota, and the Montana-North Dakota line. The lakes to be created by the various dams proposed or under construction by the Army Corps of Engineers will inundate all but short stretches of the terraces on which are situated literally hundreds of fortified and unfortified earth-lodge villages and other, earlier, occupational sites. Situated near the northern limit of agriculture but heavily populated by sedentary, horticultural people for a period of several hundreds of years, this anthropologically fascinating area has been barely touched scientifically.
