ItemAn Annotated Checklist of the Freshwater Fishes of Texas, With Keys to Identification of Species(Texas Academy of Science, 2008-07) Hubbs, Clark; Edwards, Robert; Garrett, GaryForty-nine families and 268 species of fishes are known to inhabit the freshwaters of Texas. We report on the distribution and status of these fishes and provide a key to their identification. Of the native fishes originally found in Texas, five taxa, Cyprinella lutrensis blairi (Maravillas red shiner), Notropis orca (phantom shiner), N. simus simus (Rio Grande bluntnose shiner), Gambusia amistadensis (Amistad gambusia) and G. georgei (San Marcos gambusia) are apparently extinct, and four, Hybognathus amarus (Rio Grande silvery minnow), Notropis simus pecosensis (Pecos bluntnose shiner), Oncorhynchus clarki virginalis (Rio Grande cutthroat trout) and Gambusia senilis (blotched gambusia) appear to be extirpated from the state. Over 40 percent of the remaining primary freshwater species are of conservation concern and in some need of protection. ItemClark Hubbs Student Research Award: A Synoptic Vita of his Lifetime Achievements in Fisheries Biology for Which this Award is Honored(2005-01) Texas Chapter of the American Fisheries Society ItemGeographic variation in morphology of Agosia chrysogaster, a Sonoran desert cyprinid fish(Arizona State Univeristy, Tempe, AZ, 1987-05) Hendrickson, Dean A.Morphometric analyses of Agosia chrysogaster (Girard) indicated a northern morph native to Bill Williams, Gila, Sonoyta and de la Concepcion basins of Arizona, New Mexico and Sonora, and a southern form from Willcox Playa of Arizona and Rios Sonora, Yaqui, Mayo, Fuerte and Sinaloa of Sonora and Sinaloa, Mexico. The latter is smaller, and less sexually dimorphic, but has longer pre- and postdorsal body lengths. Populations in the geographically intermediate Rios Sonoyta and Sonora are morphologically intermediate. Males differ more between morphs than do females. Meristic characters show considerable overlap between morphs, but the northern form has higher mean lateral line scale counts. Highly tuberculate nuptial males, characteristic of the northern morph, were not found in the south, nor were "spawning" pits characteristic of breeding activities of the former. Morphs differ on a multivariate axis on which temporal variation at single localities is also reflected. Distances among some intra-locality samples on this axis were greater than least inter-morph morphological distances. Measures of morphological dissimilarity were weakly correlated with inter-sample differences in elevation, latitude, and longitude, but more highly correlated with an index of hydrologic isolation among localities. Differentiation among basins thus appears to reflect hydrographic isolation, rather than ecological conditions. Electrophoretic data on A. chrysogaster produced relationships patterns largely incongruent with results of the morphological analyses, and with unexpected geographic area relationships. ItemInventory of the Clark Hubbs' Papers, 1946-1999(2011-08-12) D'Antonio, SaraDr. Clark Hubbs was a professor in the School of Biological Sciences, Section of Integrative Biology at The University of Texas at Austin, for his entire career, from 1949 until his death in 2008. He founded the University’s Fish Collection, which is now part of the Texas Natural History Collections and deposited more fish specimens than anyone else has, or likely ever will. Hubbs published over 300 articles during his career and his idea for a book on the fishes of Texas began the Fishes of Texas Project. The Clark Hubbs Papers measures 24.5 linear feet and includes research notes, reprints, field notes, manuscripts, and some student records dating from 1946-1999.
