River restoration
[1] River restoration is at the forefront of applied hydrologic science. However, many river restoration projects are conducted with minimal scientific context. We propose two themes around which a
Relationships between Woody Debris and Fish Habitat in a Small Warmwater Stream
Abstract Abundance of woody debris was manipulated in a small Illinois stream to determine the importance of this material to fish. When a stream reach was divided along midchannel, and debris was
Fish Traits: A Database of Ecological and Life‐history Traits of Freshwater Fishes of the United States
A database of > 100 traits for 809 fish species found in freshwaters of the conterminous United States, including 37 native families and 145 native genera is compiled.
Ecological Attributes of Extinction‐Prone Species: Loss of Freshwater Fishes of Virginia
I examined patterns of extirpation among Virginia’s 197 historically native freshwater fish species to address the following questions: (1) Are extinction-prone species ecologically distinct? and (2)
Local vs. regional influences on local diversity in stream fish communities of Virginia
Local species richness is a function of many factors operating at multiple spatial and temporal scales. We examined stream fish communities from regions throughout Virginia to assess (1) the relative
Ecological correlates of fish movement in a network of Virginia streams
Relationships between three attributes of movement and 15 ecological variables are examined in order to identify factors that influence fish movement and predict how populations respond to environmental change.
Biological Integrity versus Biological Diversity as Policy DirectivesProtecting biotic resources
Two phrases — biological integrity and biological diversity — have joined the lexicon of biologists and natural resource managers during the past two decades and are widely used by the media, citizens, policy makers, and some biologists without adequate attention to the concepts they embody.
The Natural Imperative for Biological Conservation
Five aspects of naturalness are examined in the context of biological conservation, including its utility, its assessment, its relationship to values and ethics, its relation to Values and Ethics, and the implications of adopting it as a guiding concept.
