PROCEEDINGS OF THE DESERT FISHES COUNCIL 1992 - VOLUME MV <br />WILLIAMS, J. E.*; WILLIAMS, C. D. (JW - Bureau of Land Management, Washington, D.C.; CW - USDA Forest Service, Washington. <br />D.C.) <br />A cooperative strategy to "Bring Back The Natives" to our public lands / Una estrategia <br />cooperativa para "Regresar a los Nativos" a nuestros terrenos publicos <br />KEYWORDS: biodiversity; watershed; restoration; public lands; native species <br />ABSTRACT <br />The 191 million acres of National Forest System lands together with the more than 270 million acres of Bureau of <br />Land Management public lands comprise nearly 70% of all federal lands in the United States. These multiple-use lands <br />provide vast opportunities for restoration of aquatic biodiversity. In 1991, the National Fish and Wildlife Foundation <br />joined both of these agencies in a cooperative effort to restore the biotic integrity of entire streams where the USDA <br />Forest Service and BLM manage large portions of the watersheds. Twenty-one streams in 10 states were targeted under <br />this strategy in 1992. During 1993, the program has expanded to 34 projects in 13 states. Projects are based on the <br />premises of changes in land management prescriptions, watershed level restoration, and the involvement of as many <br />landowners as possible. <br />RESUMEN <br />Los 191 millones de acres de terreno, del sistema de Bosques Nacionales junto con los mas de 270 millones de <br />acres de terrenos p6blicos de la Agencia de Manejo del suelo comprenden cerca de los del 70% de todo el terreno federal <br />en los Estados Unidos. Estos terrenos de use multiple proveen de oportunidades pars la restauraci6n de la biodiversidad <br />acuatica. En 1991,1a Fundaci6n National para la vida silvestre y la pesca se uni6 con estas agencies en un esfuerzo <br />cooperativo para restaurar la integridad bi6tica'de rfos completos donde el servicio forestal y de la Agencia de Manejo <br />de Suelo manejan grandes porciones de las cuencas hidrograficas. Veintidn rios en 10 estados fueron seleccionados bajo <br />esta estrategia en 1992. Durante 1993, el programa se ha expandido a 34 proyectos en 13 estados. Los proyectos estan <br />basados en las premisas de cambios en las prescriptions del manejo del suelo, nivel de restauraci6n de cuencas y el <br />mayor involucramiento de propietarios de tierra como file posible. L.*; MAYDEN, R. WOOD,.R. M. (Department of Biological Sciences, University of Alabama) <br />Allozyme evolution in the Cyprinella fornzosa species group (Teleostei: Cyprinidae): A case <br />study of speciation and historical biogeography in the desert southwest / Evoluci6n <br />aloenzimatica en el grupo de especies Cyprinellaformosa (Teleostei: Cyprinidae): Un caso <br />de estudio de especiacidn y biogeografia histdrica en el desierto del Suroeste <br />KEYWORDS: allozymes; systematics; speciation; Cyprinidae; Cyprinella; biogeography <br />ABSTRACT <br />The Cyprinella formosa species group is a monophyletic group inclusive of two species: Cyprinella formosa and <br />Cyprinella bocagrande. The beautiful shiner, Cyprinella formosa, occurs in the interior drainages of the Guzman Basin <br />and disjunct northern and southern headwaters of the Rio Yaqui. The largemouth shiner, Cyprinella bocagrande, is <br />endemic to Ojo Solo in the Bols6n de los Muertos, part of the Guzman Basin. <br />During Kansan period rivers of the Guzman Basin (and Ojo Solo) formed tributaries to the extensive pluvial Lake <br />Palomas. This once continuous aquatic system presumably provided suitable habitat for a widespread ancestral species <br />to the C. formosa species group. Subsequent isolation of portions of Lake Palomas resulted in a series of endorheic <br />drainages and isolated gene pools for members of the C. formosa species group. <br />In this study we investigate genetic variability (43 loci) in C. formosa from five drainages and C. bocagrande from <br />Ojo Solo. Using Cyprinella lepida and Cyprinella lutrensis as outgroups, phylogenetic hypotheses (distance Wagner, <br />PAUP, FREQPARS) are used to evaluate likely modes of speciation and rates of divergence operating within this species <br />group. <br />RESUMEN <br />El grupo de especies Cyprinella formosa es un grupo monofiletico integrado por dos especies: Cyprinella formosa <br />y Cyprinella bocagrande. La sardinita yaqui, Cyprinella formosa, ocurre en los cauces internos de la cuenca del Rfo <br />Guzman y cabeceras disyuntas del norte y Sur de el Rfo Yaqui. La sardinita bocagrande, C. bocagrande, es endemica <br />a la localidad Ojo Solo en el Bols6n de Muertos, el cual es parte de la cuenca del Rfo Guzman. <br />Durante el perfodo Kansaniano, los rios de la cuenca del Rfo Guzman (y Ojo Solo) formaron tributarios al extenso <br />lago pluvial Palomas. Este entonces sistema acudtico continuo, presumiblemente provey6 de habitat adecuado para una <br />especie ancestral bien distribuida del grupo C. formosa. El aislamiento subsecuente de las porciones del Lago Palomas <br />result6 en una serie de cauces endorreicos y grupos de genes aislados para miembros del grupo de especies C. forntosa. <br />17
