Ghost shiner
The ghost shiner (''Notropis buchanani'') is a North American species of freshwater fish belonging to the Cyprinidae family. It is generally characterized as being a small bodied, silvery and fusiform shaped cyprinid.〔Holm, E. and J. Houston. 1993. "Status of the ghost shiner, ''Notropis buchanani'', in Canada". ''Can. Field Naturalist'' 107:440-445.〕 ''Notropis buchanani'' is morphologically similar to and often mistaken for the Mimic Shiner (''Notropis volucellus''), which is evident by its former classification as a subspecies of ''Notropis volucellus''.〔Trautman, M. B. 1981. ''The Fishes of Ohio''. Ohio State University Press. 782 pp.〕
==Geographic distribution==
The current range for ''Notropis buchanani'' extends from the Mississippi River basin in the southern United States to Ontario in southern Canada. Populations have been reported in eastern Kansas, southeastern Nebraska, western Oklahoma and south to northern Alabama, Mississippi, and Louisiana. Populations of ''N. buchanani'' are also present in Gulf slope drainages in Texas,〔Hubbs, C., R. J. Edwards, and G. P. Garrett. 1991. "An annotated checklist of the freshwater fishes of Texas, with keys to the identification of species". ''The Texas Journal of Science''. 43(4):1-56.
〕 Louisiana, and Mexico. In 1993, populations were found in southern Ontario.〔 The trend in the United States is that the farther north the state is from the Gulf Coast, the less secure populations of ''N. buchanani'' become. In Ontario, the population is apparently stable.
The first population of ''Notropis buchanani'' in Ontario was discovered in the Thames River watershed in 1979.〔Holm, E. and G.A. Coker. 1981. "First Canadian records of the ghost shiner (''Notropis buchanani'') and the orangespotted sunfish (''Lepomis humilis'')". ''Can. Field Naturalist'' 95: 210-211.〕 After the discovery, the Canadian Museum of Nature was checked for similar species of ''Notropis'', and a specimen of ''Notropis buchanani'' was found to have previously been collected from Mollys Creek in 1972.〔Knott, Edward and Dean Fitzgerald. 2000. "Comparative Morphology and Taxonomic status of the Ghost Shiner, ''Notropis buchanani'' in Canada". ''Environmental Biology of Fishes'' 59: 385-392.〕 The population in southern Ontario has been thought to have been introduced in the 1970s; however, recent studies suggest that it is native to Canada due to natural migration after deglaciation.
