In order to develop biological indicators capable of assessing the biological conditions of state rivers and streams, the North Dakota Department of Health is developing a calibrated multi-metric index of biotic integrity (IBI) based on aquatic macroinvertebrate data for each ecoregion. Macroinvertebrates are common inhabitants of rivers and streams and vital links in the movement of energy through the food web.

The purpose of this project is to develop a set of benthic macroinvertebrate multimetric IBIs that can be used to assess the biological condition of perennial rivers and streams in North Dakota ... Macroinvertebrates are excellent indicators of aquatic health. Additionally, due to the range of life spans and varying needs throughout their life span, macroinvertebrates are excellent indicators of chronic and acute pollution impacts.

Download Riparian Areas Book in PDF, Epub and Kindle
The Clean Water Act (CWA) requires that wetlands be protected from degradation because of their important ecological functions including maintenance of high water quality and provision of fish and wildlife habitat. However, this protection generally does not encompass riparian areasâ€"the lands bordering rivers and lakesâ€"even though they often provide the same functions as wetlands. Growing recognition of the similarities in wetland and riparian area functioning and the differences in their legal protection led the NRC in 1999 to undertake a study of riparian areas, which has culminated in Riparian Areas: Functioning and Strategies for Management. The report is intended to heighten awareness of riparian areas commensurate with their ecological and societal values. The primary conclusion is that, because riparian areas perform a disproportionate number of biological and physical functions on a unit area basis, restoration of riparian functions along America's waterbodies should be a national goal.

Download Urban Stormwater Management in the United States Book in PDF, Epub and Kindle
The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.

Download The Black-Tailed Prairie Dog Book in PDF, Epub and Kindle
In The Black-Tailed Prairie Dog, John L. Hoogland draws on sixteen years of research at Wind Cave National Park, South Dakota, in the United States to provide this account of prairie dog social behavior. Through comparisons with more than 300 other animal species, he offers new insights into basic theory in behavioral ecology and sociobiology. Hoogland documents interactions within and among families of prairie dogs to examine the advantages and disadvantages of coloniality. By addressing such topics as male and female reproductive success, inbreeding, kin recognition, and infanticide, Hoogland offers a broad view of conflict and cooperation. Among his surprising findings is that prairie dog females sometimes suckle, and at other times kill, the offspring of close kin. Enhanced by more than 100 photographs, this book illuminates the social organization of a burrowing mammal and raises fundamental questions about current theory. As the most detailed long-term study of any social rodent, The Black-Tailed Prairie Dog will interest not only mammalogists and other vertebrate biologists, but also students of behavioral and evolutionary ecology.

Download Successes, Limitations, and Frontiers in Ecosystem Science Book in PDF, Epub and Kindle
Ecosystem research has emerged in recent decades as a vital, successful, and sometimes controversial approach to environmental science. This book emphasizes the idea that much of the progress in ecosystem research has been driven by the emergence of new environmental problems that could not be addressed by existing approaches. By focusing on successes and limitations of ecosystems studies, the book explores avenues for future ecosystem-level research.
