THE NATURAL FLOW REGIME. A PARADIGM FOR RIVER CONSERVATION AND RESTORATION
- N. Poff, J. Allan, J. Stromberg
- Environmental Science
- 1 December 1997
H umans have long been fascinated by the dynamism of free-flowing waters. Yet we have expended great effort to tame rivers for transportation, water supply, flood control, agriculture, and power…
Global biodiversity scenarios for the year 2100.
This study identified a ranking of the importance of drivers of change, aranking of the biomes with respect to expected changes, and the major sources of uncertainties in projections of future biodiversity change.
Landscape Filters and Species Traits: Towards Mechanistic Understanding and Prediction in Stream Ecology

- 1 June 1997
Multi-scale, mechanistic understanding of species-environment relations will likely contribute to better predictions about large scale problems, such as the establishment and spread of exotic species or alterations in community composition with changing land use or climate.
The ecological limits of hydrologic alteration (ELOHA): a new framework for developing regional environmental flow standards
- N. Poff, B. Richter, A. Warner
- Environmental Science
- 2007
SUMMARY 1. The flow regime is a primary determinant of the structure and function of aquatic and riparian ecosystems for streams and rivers. Hydrologic alteration has impaired riverine ecosystems on…
Redundancy and the choice of hydrologic indices for characterizing streamflow regimes
The utility of hydrologic indices for describing various aspects of streamflow regimes has resulted in their increased application in riverine research. Consequently, researchers are now confronted…
The Network Dynamics Hypothesis: How Channel Networks Structure Riverine Habitats
- L. Benda, N. Poff, M. Pollock
- Environmental Science
- 1 May 2004
The spatial structure of river networks regulates how stochastic watershed disturbances influence the morphology and ages of fluvial features found at confluences, and allows the development of testable predictions about how basin size, basin shape, drainage density, and network geometry interact to regulate the spatial distribution of physical diversity in channel and riparian attributes throughout a river basin.
The challenge of providing environmental flow rules to sustain river ecosystems.

- 1 August 2006
A generic approach is proposed that incorporates essential aspects of natural flow variability shared across particular classes of rivers that can be validated with empirical biological data and other information in a calibration process and can bridge the gap between simple hydrological "rules of thumb" and more comprehensive environmental flow assessments and experimental flow restoration projects.
Ecological responses to altered flow regimes: a literature review to inform the science and management of environmental flows
- N. Poff, J. Zimmerman
- Environmental Science
- 2010
SUMMARY 1. In an effort to develop quantitative relationships between various kinds of flow alteration and ecological responses, we reviewed 165 papers published over the last four decades, with a…
Functional trait niches of North American lotic insects: traits-based ecological applications in light of phylogenetic relationships

- 1 December 2006
A new database on species-trait composition of North American lotic insects is created and some ideas about how specific trait linkages, statistical correlations among traits, and evolutionary lability of traits can be used in combination with a mechanistic understanding of trait response along environmental gradients to select robust traits useful for a more predictive community ecology are concluded.
