Predation Vulnerability and Trophic Interactions of Pallid Sturgeon Scaphirhynchus albus
Recruitment of the federally endangered pallid sturgeon Scaphirhynchus albus in the Missouri River has been absent or at levels too low to sustain the population. Mortality of juvenile fishes is often greatest during their first year of life, and may have large implications for recruitment dynamics …

The Development and Application of a Larval Pallid Sturgeon (Scaphirhynchus albus) Bioenergetics Model
<p>Pallid Sturgeon Scaphirhynchus albus are native fish of the Missouri and lower Mississippi River basins and currently listed as an endangered species under the Federal Endangered Species Act. As a result of anthropogenic alterations within the Missouri River, including dredging, channelization, …

Determinants of Growth and Survival of Larval Pallid Sturgeon: A Combined Laboratory and Field Approach
… which was identified as potential cause for pallid sturgeon Scaphirhynchus albus recruitment failure. Consequently, recovery effort has focused on habitat restoration, however, ecological requirements of larval pallid sturgeon are largely unknown. To inform recovery efforts, we studied the …

Influence of Diet and Environmental Variation on Physiological Responses of Juvenile Pallid Sturgeon (Scaphirhynchus albus)
Shortly after the pallid sturgeon Scaphirhynchus albus was listed as federally endangered in 1990, a recovery plan was drafted to outline efforts to restore the pallid sturgeon throughout its’ native range in the Missouri and middle and lower Mississippi rivers. The plan set forth a number of …

Modeling Spatial Distribution and Habitat Associations for Juvenile Pallid Sturgeon (Scaphirhynchus albus) in the Missouri River
Monitoring and assessment of the endangered pallid sturgeon Scaphirhynchus albus population is essential to the recovery of the species. Movement and distribution of pallid sturgeon is generally documented using radio telemetry methods. However, because of the time and cost involved in tracking …

Factors affecting habitat separation in the pallid flycatcher Melaenornis pallidus and Marico flycatcher Melaenornis mariquensis
Factors affecting habitat separation in Pallid Flycatchers Melaenornis pallidus and Marico Flycatchers Melaenornis mariquensis were studied from June 1980 to June 1982 at the Nylsvley Nature Reserve in the central Transvaal. The main emphasis of the study, which is divided into two sections, was to …

ECOLOGY AND COEXISTENCE OF SCAPHIRHYNCHUS STURGEON AT MULTIPLE SCALES
… and habitat loss. The federally endangered pallid sturgeon (Scaphirhynchus albus) and a congener, the threatened shovelnose sturgeon (S. platorynchus) are two species that depend solely on the large rivers of North America. Both species have experienced declines from habitat loss within the …

Isolation and Characterization of Regulatory Peptides from Two Tetraploid Species, the Pallid Sturgeon, Scaphirhynchus albus, and the African Clawed Frog, Xenopus laevis
… from gastroenteropancreatic (GEP) tissue of the pallid sturgeon, Scaphirhynchus albus. Two forms of gastrin-releasing peptide (GRP), neuromedin C, two forms of PYY, glucagon-like peptide IB (GLP-1B), and VIP were isolated from gastrointestinal extracts from the African clawed frog, Xenopus …

Development and Application of a Spatially-explicit Model for Estimating Growth of Age-0 Pallid Sturgeon in the Missouri River
… to the Missouri and Mississippi rivers, the Pallid Sturgeon (Scaphirhynchus albus) has been listed as an endangered species since 1990. Construction of six main-stem dams along the Missouri River has altered spawning and nursery habitats, while obstructing upstream migrations of adults and …

Macroinvertebrate Composition and Patterns of Prey Use By Juvenile Pallid Sturgeon (Scaphirhynchus albus) in the Missouri River, South Dakota, and Nebraska
… of the Niobrara River. We collected 31 juvenile pallid sturgeon during summer 2006 for diet analysis, of which 21 had prey in their stomachs. Percent occurrence of predominant prey was Ceratopogonidae (81%), Isonychiidae (67%), Chironomidae (52%), and fish (24%). Diets as percent composition by …
