"Longitudinal Patterns in the Fish Assemblages of An Ozark Stream,"
Fish species diversity in Spring Creek (Oklahoma) of the Neosho River drainage was positively correlated with habitat diversity, and in the upper half of the stream was inversely correlated with distance from the stream source. Diversity was comparably high at downstream and upstream locations. The unusual pattern in species diversity, which is contrary to the usual pattern of low upstream and high downstream diversity, is likely the result of high fish species diversity existing only in diverse habitats, while in interrupted Spring Creek habitat diversity does not generally increase in a downstream direction.
