Characterizing fish community diversity across Virginia landscapes: Prerequisite for conservation Characterizing fish community diversity across Virginia landscapes: Prerequisite for conservation
The number of community types occurring within landscapes is an important, but often unprotected, component of biological diversity. Generally applicable protocols for characterizing community diversity need to be developed to facilitate conservation. We used several multivariate techniques to analyze geographic variation in the composition of fish communities in Virginia streams. We...

Transport, retention, and ecological significance of woody debris within a large ephemeral river Transport, retention, and ecological significance of woody debris within a large ephemeral river
The spatiotemporal patterns and ecological significance of the retention of coarse particulate organic matter and large woody debris have been intensively studied in perennial rivers and streams but are virtually unknown in ephemeral systems. We examined the influence of 2 features characteristic of ephemeral systems, downstream hydrologic decay and in-channel tree growth, on the...

Factors influencing stream fish recovery following a large-scale disturbance Factors influencing stream fish recovery following a large-scale disturbance
We examined fish distribution and abundance in erosional habitat units in South Fork Roanoke River, Virginia, following a fish kill by using a reachwide sampling approach for 3 species and a representative-reach sampling approach for 10 species. Qualitative (presence-absence)and quantitative (relative abundance) estimates of distribution and abundance provided consistent measures of fish...

Estimating number of species and relative abundances in stream-fish communities: effects of sampling effort and discontinuous spatial distributions Estimating number of species and relative abundances in stream-fish communities: effects of sampling effort and discontinuous spatial distributions
We sampled fishes and measured microhabitat in series of contiguous habitat units (riffles, runs, pools) in three Virginia streams. We used Monte Carlo simulations to construct hypothetical series of habitat units, then examined how number of species, similarity in relative abundances, and number of microhabitats accumulated with increasing number of habitat units (i.e., sampling effort)
