In 2001, the U.S. Geological Survey, in cooperation with Colorado Springs City Engineering, began a study to better understand the relations between environmental characteristics and biological communities in the Fountain Creek basin in order to aide water-resource management and guide future monitoring activities. To accomplish this task, environmental (streamflow, habitat, and water chemistry) aAuthorsRobert E. Zuellig, James F. Bruce, Robert W. Stogner, Sr.Changes in dissolved organic material determine exposure of stream benthic communities to UV-B radiation and heavy metals: Implications for climate change
Changes in regional climate in the Rocky Mountains over the next 100 years are expected to have significant effects on biogeochemical cycles and hydrological processes. In particular, decreased discharge and lower stream depth during summer when ultraviolet radiation (UVR) is the highest combined with greater photo-oxidation of dissolved organic materials (DOM) will significantly increase exposureAuthorsW.H.

In 2005, the U.S. Geological Survey and the City of Longmont, Colo., began a study to document chemical characteristics of St. Vrain Creek that had previously been unavailable either due to high cost of analysis or lack of analytical capability. Stream samples were collected at seven sites on St. Vrain Creek during the spring of 2005 and 2006 for analysis of wastewater compounds. A Lagrangian-sampAuthorsRobert E. Zuellig, Lori A.

In 2003, the U.S. Geological Survey, in cooperation with Colorado Springs City Engineering, began a study to evaluate the influence of urbanization on stream ecosystems. To accomplish this task, invertebrate, fish, stream discharge, habitat, water-chemistry, and land-use data were collected from 13 sites in the Fountain Creek basin from 2003 to 2005.

The U.S. Geological Survey (USGS) conducted a study from 2002 through 2003 through its National Water-Quality Assessment (NAWQA) Program to determine the effects of urbanization on the physical, chemical, and biological characteristics of stream ecosystems along the Front Range of the Rocky Mountains.

This report describes the effects of urbanization on physical, chemical, and biological characteristics of stream ecosystems in 28 basins along an urban land-use gradient in the South Platte River Basin, Colorado and Wyoming, from 2002 through 2003. Study basins were chosen to minimize natural variability among basins due to factors such as geology, elevation, and climate and to maximize coverageAuthorsLori A. Sprague, Robert E. Zuellig, Jean A.

The U.S. Geological Survey, in conjunction with the Great Sand Dunes National Park and Preserve and its cooperators, did an extensive inventory of certain targeted aquatic-insect groups in the Sand Creek Basin, Great Sand Dunes National Park and Preserve, to establish a species list for future monitoring efforts. Study sites were established to monitor these groups following disturbance events. SuAuthorsRobert E. Zuellig, Boris C. Kondratieff, David E. Ruiter, Richard A.

Pteronarcys pictetii Hagen nymphs were collected and reared from the South Platte River at Julesburg in eastern Colorado. Including P. pictetii, eight species are now known from Colorado that exhibit eastern North American affinities, Paracapnia angulata Hanson, Taeniopteryx burksi Ricker and Ross, Taeniopteryx parvula Banks, Acroneuria abnormis (Newman), Perlesta decipiens (Walsh), Isoperla bilinAuthorsR.E.

Qualitative collections of aquatic insects were made at Fort Sill, Lawton, Oklahoma, between 2002 and 2004. Ephemeroptera, Plecoptera, Trichoptera, Odonata, Coleoptera, aquatic Heteroptera, Neuroptera, and Megaloptera were targeted. Additional records are included from a survey that took place in 1999. More than 11,000 specimens from more than 290 collections were examined. Based on the current unAuthorsR.E. Zuellig, B.C. Kondratieff, J.P. Schmidt, R.S. Durfee, D.E. Ruiter, I.E.

In summary, 88 species of stoneflies are now known from MRNP, representing 65% of the recorded Washington State fauna (Stark and Baumann 2005). At least two of these species are apparently restricted to the MRNP, Soliperla fenderi (Jewett) (Stark and Gustafson 2004) and P. lechleitneri.AuthorsB.C. Kondratieff, R.A. Lechleitner, R.E.
