Water Quality Sampling, Analysis and Annual Load Determinations for TSS, Nitrogen and Phosphorus at the Washington County Road 76 Bridge on Ballard Creek [PDF]
The Illinois River Basin has experienced water quality impairment from non-point source pollution for many years. This fact was well documented in the State of Arkansas\u27 Water Quality Assessment report, the Soil Conservation Service River Basin Study,

A numerical tool to integrate biophysical diversity of a large regulated river: hydrobiogeochemical bases. The case of the Garonne River (France) [PDF]
This article presents the bases of a hydrobiogeochemical model of the Garonne River (southwest France) which has been developed to integrate physical and biological processes during summer low-water periods. The physical part of this model is composed of

Phenotypic Plasticity Across Gradients of Predation and Competition in Larval Amphibians
Many taxa encounter a wide range of conditions for any particular environmental variable and they experience variation in multiple environmental variables simultaneously, which may have interactive effects if different environmental types induce opposing phenotypes.

Konza Prairie Biological Station, located within one of the largest remaining areas of native tallgrass prairie, is unique in that grazing and prescribed burn treatments, as well as surface water permanence, vary spatially. We found that aquatic macroinvertebrate communities vary with streamflow permanence, but not grazing presence or prescribed burns ...

Despite several negative effects of browning, there are no sufficient bioindicators to monitor it. In this study, the effects of water quality on the photosynthetic pigment content of periphyton grown on artificial substrata in different depths were ...

Changes in the algal composition, bacterial metabolic activity and element content of biofilms developed on artificial substrata in the early phase of colonization [PDF]
Changes in the algal composition and metabolic profiles of bacterial communities as well as the inorganic components were studied on artificial substrata during the early phase of biofilm formation under laboratory conditions in September 2002 and 2003 ...

Abstract All organisms contain carbon, nitrogen, and phosphorus in widely ranging amounts and proportions. Integrating existing datasets enables quantification of this variation at global scales. Such efforts could leverage ecological stoichiometry theory, the study of elemental supply and imbalances in ecological interactions, to connect ecological ...

In a benthic community on a continuous flat granite substrate in a third-order coastal forest stream, the dominant chironomid (Cricotopus) increased in number when shrimps (Macrobrachium olfersi and Potimirim glabra) and baetid ephemeropterans were ...
