The drainage of the Negro River is the most important watercourse in the Patagonia ecoregion and, together with the Colorado river basin, define an ecotone, i.e., a zoogeographic transition, where coexist the Brazilian and Patagonian lineages of freshwater fishes. The Patagonia ecoregion has 29 fish species, 15 native and the remaining introduced. For this study, the ichthyofauna of seven locations in the lower course of the Negro river drainage were sampled along two years. Gillnets, coastal trawls, cast nets, river trammel nets and fishing rods were used to catch specimens. A total of 13 species belonging to nine orders and 11 families were collected. The families Atherinopsidae and Characidae show the highest species richness and one exotic species, Cyprinus carpio Linnaeus, 1758, was recorded. The origin and distribution of some species is discussed, considering the role of human action and certain environmental factors.

Abstract Pb isotope data from over 2400 detrital K-feldspars in >50 modern sands sampled across the Mississippi-Missouri River drainage basin of North America have been collected in order to construct the first basin-wide provenance model using geochemical signals in a framework, rather than an accessory, mineral. This study represents a critical initial step in understanding the long-term routing of framework sand grains through the Mississippi-Missouri River drainage basin. Four unique Pb isotopic groups, otherwise petrographically and geochemically indistinguishable, are identifiable. Source comparisons reveal two groups corresponding to the Archean Superior and Wyoming terranes to the north of the catchment. The remaining two Pb groups represent a mixture of Appalachian, Grenville and older Granite-Rhyolite, and Yavapai-Mazatzal sourced-grains in the east of the catchment, with noteworthy input from Cenozoic volcanic rocks along the western fringe of the catchment to tributaries west of the Mississippi River, confirming prior assertions of zircon recycling in the lower drainage basin. Tracing suites of Pb isotopic groups provide a detailed map of previously undocumented tributary mixing and reveals the importance of long-lived, naturally formed impoundments in the Upper Mississippi River, which locally sequester and release sand. Tentative proportioning of sediment contributions to the terminus of the Mississippi River from individual tributaries produces similar results to recent U-Pb zircon models, boding well for the use of framework grain based modeling of sediment fluxes. The study is the largest application of Pb-in-K-feldspar fingerprinting to date and advocates its potential as a new and necessary tool for constraining relative source contributions to sinks—which will have wide applicability—especially if combined with provenance information from detrital grains of varying resilience, within large drainage systems.

Topographic and geologic map interpretation strongly suggests the eastern Montana Redwater River valley eroded headward across large southeast-oriented ice-marginal melt water floods. The north-oriented Redwater River heads in an area to the south of recognized continental glaciation and flows into the recognized glaciated region before joining the east-oriented Missouri River. Detailed topographic maps show the eastern drainage divide is asymmetric with steeper slopes on the Redwater River side and is crossed by shallow dry valleys linking northwest-oriented Redwater River tributaries with southeast-oriented streams that flow as barbed tributaries to the northeast-oriented Yellowstone River. The western drainage divide is also crossed by shallow dry valleys linking northwest-oriented drainage routes to north-oriented Missouri River tributaries with southeast-oriented and barbed tributaries to the northeast- and north-oriented Redwater River. Alluvium from upstream Yellowstone River source areas found within the Redwater River drainage basin suggests the Redwater River and much longer Yellowstone River valleys eroded headward from a continental ice sheet margin as headward erosion of the larger Yellowstone River valley across the southeast-oriented flood flow was supplemented by northeast- and north-oriented flow moving at the present day Redwater-Yellowstone River drainage divide elevation.

The ongoing research has the following objectives. 1. Establish baseline data on vertebrate populations and their ecological distributions. 2. Identify and estimate population sizes for state and federally listed threatened or endangered species and develop management recommendations for them. 3. Identify and estimate population sizes of exotic species. The study will provide basic management information relative to threatened or endangered species and relative to maintenance of native species in the remnants of native prairie and Missouri River bottom land on the KNRI.
