Spatially explicit habitat models for 28 fishes from the Upper Mississippi River System (AHAG 2.0) Spatially explicit habitat models for 28 fishes from the Upper Mississippi River System (AHAG 2.0)
Environmental management actions in the Upper Mississippi River System (UMRS) typically require pre-project assessments of predicted benefits under a range of project scenarios. The U.S. Army Corps of Engineers (USACE) now requires certified and peer-reviewed models to conduct these assessments. Previously, habitat benefits were estimated for fish communities in the UMRS using the...

Are two systemic fish assemblage sampling programmes on the upper Mississippi River telling us the same thing? Are two systemic fish assemblage sampling programmes on the upper Mississippi River telling us the same thing?
We applied an Index of Biotic Integrity (IBI) used on Wisconsin/Minnesota waters of the upper Mississippi River (UMR) to compare data from two systemic sampling programmes. Ability to use data from multiple sampling programmes could extend spatial and temporal coverage of river assessment and monitoring efforts. We normalized for effort and tested fish community data collected by the...

Challenges in merging fisheries research and management: The Upper Mississippi River experience Challenges in merging fisheries research and management: The Upper Mississippi River experience
The Upper Mississippi River System (UMRS) is a geographically diverse basin extending 10?? north temperate latitude that has produced fishes for humans for millennia. During European colonization through the present, the UMRS has been modified to meet multiple demands such as navigation and flood control. Invasive species, notably the common carp, have dominated fisheries in both...

Nonnative Fishes in the Upper Mississippi River System Nonnative Fishes in the Upper Mississippi River System
The introduction, spread, and establishment of nonnative species is widely regarded as a leading threat to aquatic biodiversity and consequently is ranked among the most serious environmental problems facing the United States today. This report presents information on nonnative fish species observed by the Long Term Resource Monitoring Program on the Upper Mississippi River System a...

Flood trends and river engineering on the Mississippi River system Flood trends and river engineering on the Mississippi River system
Along >4000 km of the Mississippi River system, we document that climate, land-use change, and river engineering have contributed to statistically significant increases in flooding over the past 100-150 years. Trends were tested using a database of >8 million hydrological measurements. A geospatial database of historical engineering construction was used to quantify the response of flood...

Assessing habitat use by breeding Great Blue Herons (Ardea herodias) on the Upper Mississippi River, USA Assessing habitat use by breeding Great Blue Herons (Ardea herodias) on the Upper Mississippi River, USA
Approximately 7,610 to 3,175 pairs of Great Blue Herons (Ardea herodias) nested along 420 river km of the Upper Mississippi River (UMR) from 1993 to 2003. Numbers declined precipitously in the mid-1990s stabilizing somewhat in the early 2000s. The average number of nests in colonies was 349 (SD = 283). Annual colony turn over rate for the eleven year period was 0.15 and ranged from 0.06...

Influential environmental gradients and spatiotemporal patterns of fish assemblages in the unimpounded Upper Mississippi River Influential environmental gradients and spatiotemporal patterns of fish assemblages in the unimpounded Upper Mississippi River
We investigated variation of fish assemblages in response to environmental factors using Long Term Resource Monitoring Program data. Data were collected from 1993 to 2000 from five physical habitats in the unimpounded upper Mississippi River. We captured 89 species composing 18 families. Of these, 26% were fluvial specialists, 25% were fluvial dependent and 49% were generalists. The...

Fecundity of walleyes in western Lake Erie, 1966 and 1990-91 Fecundity of walleyes in western Lake Erie, 1966 and 1990-91
Ovaries were collected from walleyes (Stizostedion vitreum vitreum) in western Lake Erie just prior to spawning in 1990 and 1991 to determine current fecundity. Results were compared with fecundity determined in 1966 prior to stock rehabilitation when walleye abundance was lower and fish size at age was greater. Fecundity estimates determined from 121 fish aged 3-10 ranged from 53,000 to...
