Variance partitioning of stream diatom, fish, and invertebrate indicators of biological condition
Stream indicators used to make assessments of biological condition are influenced by many possible sources of variability. To examine this issue, we used multiple-year and multiple-reach diatom, fish, and invertebrate data collected from 20 least-disturbed and 46 developed stream segments between 1993 and 2004 as part of the US Geological Survey...

Development and application of indices to assess the condition of benthic algal communities in U.S. streams and rivers
Multi-metric indices (MMIs) are a measure of a combination of characteristics of biological communities and are used as indicators of water quality and ecological health. Although MMIs for algal communities have been developed for specific regions of the United States, none of the indices have national applicability. The MMIs described in this...
Potapova, Marina; Carlisle, Daren M. Alteration of streamflow magnitudes and potential ecological consequences: A multiregional assessment
Human impacts on watershed hydrology are widespread in the US, but the prevalence and severity of stream-flow alteration and its potential ecological consequences have not been quantified on a national scale. We assessed streamflow alteration at 2888 streamflow monitoring sites throughout the conterminous US. The magnitudes of mean annual (1980–...
Carlisle, Daren M.; Wolock, David M.; Meador, Michael R. The relative importance of physicochemical factors to stream biological condition in urbanizing basins: Evidence from multimodel inference
Many physicochemical factors potentially impair stream ecosystems in urbanizing basins, but few studies have evaluated their relative importance simultaneously, especially in different environmental settings. We used data collected in 25 to 30 streams along a gradient of urbanization in each of 6 metropolitan areas (MAs) to evaluate the relative...
Carlisle, Daren M.; Bryant, Wade L. GAGES: A stream gage database for evaluating natural and alteredflow conditions in the conterminous United States
Stream flow is a controlling element in the ecology of rivers and streams. Knowledge of the natural flow regime facilitates the assessment of whether specific hydrologic attributes have been altered by humans in a particular stream and the establishment of specific goals for stream-flow restoration. Because most streams are ungaged or have been...
Falcone, James A.; Carlisle, Daren M.; Wolock, David M.; Meador, Michael R. Quantifying human disturbance in watersheds: Variable selection and performance of a GIS-based disturbance index for predicting the biological condition of perennial streams
Characterizing the relative severity of human disturbance in watersheds is often part of stream assessments and is frequently done with the aid of Geographic Information System (GIS)-derived data. However, the choice of variables and how they are used to quantify disturbance are often subjective. In this study, we developed a number of disturbance...
Falcone, James A.; Carlisle, Daren M.; Weber, Lisa C. Using propensity scores to estimate the effects of insecticides on stream invertebrates from observational data
Analyses of observational data can provide insights into relationships between environmental conditions and biological responses across a broader range of natural conditions than experimental studies, potentially complementing insights gained from experiments. However, observational data must be analyzed carefully to minimize the likelihood that...
Lester L. Yuan; Amina I. Pollard; Carlisle, Daren M. Predictive models for fish assemblages in eastern USA streams: implications for assessing biodiversity
Management and conservation of aquatic systems require the ability to assess biological conditions and identify changes in biodiversity. Predictive models for fish assemblages were constructed to assess biological condition and changes in biodiversity for streams sampled in the eastern United States as part of the U.S. Geological Survey's National...

A database of lotic invertebrate traits for North America
The assessment and study of stream communities may be enhanced if functional characteristics such as life-history, habitat preference, and reproductive strategy were more widely available for specific taxa. Species traits can be used to develop these functional indicators because many traits directly link functional roles of organisms with...
Vieira, Nicole K.M.; Poff, N. LeRoy; Carlisle, Daren M.; Moulton, Stephen R.; Koski, Marci L.; Kondratieff, Boris C. Macroinvertebrate assemblages associated with patterns in land use and water quality
Most national parks were designated to preserve significant natural resources. Park borders often reflect political rather than ecological boundaries. Consequently, catchments of many streams are only partially within park boundaries, and are therefore subject to land use changes and potential contamination from non-point sources outside the park...
