An abandoned stream valley, here called Florence Valley, was found in eastern Erie County, Ohio. Florence Valley is about one mile long and connects the valleys of Chappel Creek and the Vermilion River. There is evidence that Florence Valley was formed as a result of the capture of a tributary of the Vermilion River by Chappel Creek. Chappel Creek, at the junction of Florence Valley and the val...

Wine-Spring Creek basin, in the mountains of North Carolina’s Nantahala National Forest, is an ecosystem management demonstration site, iu which ecological concepts for management and restoration are tested. Large woody debris (LWD) is an important link between streams and the adjacent riparian forest, but evidence for the connection between LWD and trout in southern Appalachian streams is limi...

The Deckers Creek watershed in northern West Virginia (USA), containing a land area of 166 km2 (63 mi2), has a long history of industrial development and attendant environmental abuses from both land and water pollution practices. The water in Deckers Creek was sampled in 1974 at 29 locations along the main stem and resampled in 1999-2000 to determine water quality changes over this 25-year per...

Fecal coliform bacteria cause water quality problems for many urban areas across the United States. The objective of this study is to determine if the Irwin Creek and Sugar Creek wastewater treatment plants, located near Charlotte in Mecklenburg County, North Carolina, contribute significantly to the fecal coliform concentrations in the creeks. Fecal coliform densities in the wastewater effluen...

Caffeine has been suggested as a chemical indicator for domestic wastewater in freshwater systems, although it is not included in water quality monitoring programs. The Third Fork Creek watershed in Durham, NC, is highly urbanized, with a history of receiving untreated wastewater from leaking and overflowing sanitary sewers. The poor water quality originating in the Third Fork Creek watershed t...

Beaver dams tend to increase habitat heterogeneity by breaking up streams into lentic and lotic sections. I investigated the impact of beaver dams on macroinvertebrates in and near Cart Creek in Newbury, MA. I found that the high spatial density of dams on this small creek suppresses aquatic species diversity, but the ponds might be increasing the species diversity of terrestrial macroinvertebr...

In previous years, studies h.;.ve been conducted on several tributaries of Otsego Lake and the upper Susquehanna River that analyzed the concentrations offecal coliforms. a group of bacteria found in the intestines ofwarm blooded animals and thus indic' ve offecal contamination. Research was conducted for the duration of the SUIll:.ler ,f 1996 on the upper Susquehanna River, Hayden Creek, Shado...

Mumbai, a megacity of India, and its adjacent marine environment, though heavily stressed from various anthropogenic interferences, harbor approximatley 146 km(2) of mangrove cover. Manori creek, in the close vicinity of Mumbai, sustains relatively better mangrove formations. A creek habitat had been evaluated for its biological and environmental characteristics, and is compared with similar bu...

Questions of biotic and environmental change during deposition of the Upper Maastrichtian Hell Creek Formation require a robust and replicable system for intraformational correlation of fossil localities. In this paper, we present a carbon isotope chemostratigraphic curve based on terrestrial organic carbon. Data were taken from a complete measured section spanning the full 93 m of the Hell Cre...
