  abstract = {Examination of the distribution of sighting distances for the Roanoke
	darter \textit{Percina roanoka}, Roanoke logperch \textit{P. rex}
	and black jumprock \textit{Moxostoma cervinum} indicates that strip
	transect sighting models that assume probability of sighting remaining
	constant out to the limits of observer visibility are not appropriate
	for these benthic species. Distance sampling models that assume decreased
	sighting probability with increasing distance of the target from
	the observer provide a reasonable alternative to strip transect sighting
	models. -from Authors},
