A comparison of injectable fluorescent marks in two genera of darters: Effects on survival and retention rates
Visible implant elastomer (VIE) and injectable photonic dye (IPD), two types of injectable fluorescent marks, have shown promise in previous applications in a variety of fishes but have not been extensively tested on darters. We marked a species from each of two genera of darters, Percina and Etheostoma, in a laboratory experiment to determine the influence of VIE and IPD marks on survival and the

Using fish communities to assess streams in Romania: Initial development of an index of biotic integrity
Multimetric biotic indices increasingly are used to complement physicochemical data in assessments of stream quality. We initiated development of multimetric indices, based on fish communities, to assess biotic integrity of streams in two physiographic regions of central Romania. Unlike previous efforts to develop such indices for European streams, our metrics and scoring criteria were selected la

Ecological correlates of fish movement in a network of Virginia streams
Identifying factors that influence fish movement is a key step in predicting how populations respond to environmental change. Using mark-recapture (four species) and trap capture (eight species) data, we examined relationships between three attributes of movement and 15 ecological variables. The probability of emigrating from a reach was positively related to intermittency (one species) and body s

Demographic characteristics of American eel in the Potomac River drainage, Virginia
Studies of the demographic characteristics of the American eel Anguilla rostrata over broad spatial scales are scarce. Eels in the Shenandoah River drainage and lower Potomac River tributaries of Virginia were sampled over 2 years in both inland and near-coastal areas to describe the demographic characteristics in each area and document drainagewide patterns. Eels from the inland Shenandoah River

Development of a multimetric index for assessing the biological condition of the Ohio River
The use of fish communities to assess environmental quality is common for streams, but a standard methodology for large rivers is as yet largely undeveloped. We developed an index to assess the condition of fish assemblages along 1,580 km of the Ohio River. Representative samples of fish assemblages were collected from 709 Ohio River reaches, including 318 "least-impacted" sites, from 1991 to 2001

Designing mark-recapture studies to reduce effects of distance weighting on movement distance distributions of stream fishes
Mark-recapture studies generate biased, or distance-weighted, movement data because short distances are sampled more frequently than long distances. Using models and field data, we determined how study design affects distance weighting and the movement distributions of stream fishes. We first modeled distance weighting as a function of recapture section length in an unbranching stream. The additio

Meeting ecological and societal needs for freshwater
Human society has used freshwater from rivers, lakes, groundwater, and wetlands for many different urban, agricultural, and industrial activities, but in doing so has overlooked its value in supporting ecosystems. Freshwater is vital to human life and societal well-being, and thus its utilization for consumption, irrigation, and transport has long taken precedence over other commodities and servic

Sampling effort affects multivariate comparisons of stream assemblages
Multivariate analyses are used widely for determining patterns of assemblage structure, inferring species–environment relationships and assessing human impacts on ecosystems. The estimation of ecological patterns often depends on sampling effort, so the degree to which sampling effort affects the outcome of multivariate analyses is a concern. We examined the effect of sampling effort on site and g

Intercontinental convergence of stream fish community traits along geomorphic and hydraulic gradients
Community convergence across biogeographically distinct regions suggests the existence of key, repeated, evolutionary mechanisms relating community characteristics to the environment. However, convergence studies at the community level often involve only qualitative comparisons of the environment and may fail to identify which environmental variables drive community structure. We tested the hypoth

Determining a regional framework for assessing biotic integrity of virginia streams
The utility of an index of biotic integrity (IBI) depends on its ability to distinguish anthropogenic effects on biota amid natural biological variability. To enhance this ability, we examined fish assemblage data from least-disturbed stream sites in Virginia to determine the best way to regionally stratify natural variation in candidate IBI metrics and their scoring criteria. Specifically, we exa
